Online social networks share similar topological characteristics as real-world social networks. Many studies have been conducted to analyze the online social networks, but it is difficult to link human interests with social network software design.


The goal of this work is to propose a methodology involving the analysis of human interactions for use in designing online social network software.


We propose a novel use of social network analysis techniques to elicit requirements in order to design better  online Social network-based software. The validation  case study involved the collection of real-world data by means of a questionnaire to perform a network design construction and analysis. The key idea is to examine social network to  help in the identification of  behaviors and interests of people for better software requirements elicitation.


The validation case study demonstrates how unexpected centrality measures can emerge in real world networks. Our case study can thus conducted as a baseline for better requirement elicitation studies for online social network software design. This work also indicates how sociometric methods may be used to analyze any social domain as a possible standard practice in online social network software design. Overall, the study proved the effectiveness of the proposed novel methodology for the design of online social network software.  The methodology specifically improves upon traditional methods for software design by involving social network modeling and analysis to first study the behavior and elicit requirements to develop more resilient online social network sites.


Online social network Social network analysis Centrality measures Software requirements elicitation Software Engineering


Online social networks, also known as Social Network Sites (SNS) are web-based services allowing users to communicate with each other - whether for personal or professional usage. Boyd and Ellison have defined SNS in their  paper as “Web Based Services that allow individuals to (1) construct a public or semi-public profile within a bounded system (2) to articulate a list of other users with whom they share a connection and (3) view and traverse their list of connections and those made by others within the systems” (Ellison 2007). These social network sites not only  allow individuals to meet strangers, but also provide them the opportunity to regularly interact with their connections living across the world.

Over time, however, it is clear that many social network sites have been launched and closed due to various reasons ranging from security issues to unsatisfactory and missing features and from the launch of new and more interesting social network sites. Still, the current software design methodologies do not have any means to ensure the effective requirements elicitation for SNS. As a result, many SNS projects have failed due to hitherto unidentified reasons (Ellison 2007). We believe that the complexity of larger groups of end users is something which is currently not catered for in existing software design methodologies. The broad application of social network sites and the virtual presence of users make it challenging to elicit user requirements.

Requirement elicitation has always been considered  a long and complicated process—especially when it comes to web-based services—such as web-based information system (Yang and Tang 2003), web-based social networks, or in general, any software custom-designed for online social-network software for interaction in communities. Yang and Tang have discussed these difficulties of requirement elicitation in web-based services and have presented a three stage model of requirement elicitation:
  • When we come to web-based services, users are generally diverse.

  • It is very hard to identify key users in such a large population.

  • User requirements are always changing and even differ from culture to culture.

  • Users may grow in future.

  • There are no traditional methods to gather requirements (Interviews or observations) for web-based services as they become impractical if we consider the facts we have discussed above.

Sorenson and Skouby have  proposed the approach of requirement elicitation by using interviews (Sorensen and Skouby 2008). They however have also subsequently discussed the disadvantages of using interviews. The biggest problem is the limited number of users to be interviewed. In another paper, Tang and Yang (2006) have  discussed the drawbacks of taking survey-based studies of online users. They note  that a key problem is getting no response back from the intended members of the network.

Therefore, by considering all these previous studies, it is quite clear that online social networks are unlike traditional software. They involve building software for a much larger and much diverse group of users from the ones who can be practically interviewed. As a result, traditional software engineering approaches such as interview-taking and conducting surveys are not enough to ascertain the specific requirements related to behavior of the end-users-requirements which, if not elicited, can result in possible failure of the software. One key reason, Online SNS can fail is because traditional software requirement elicitation techniques do not have any means of discovery of human behavioral influences. The key novel idea in the proposed methodology is to employ the  use of social network modeling and analysis (Niazi and Hussain 2012) to understand the behaviors and interests of people for better elicitation of  software requirements.

Social networks can be analyzed by analyzing structural characteristics of the network. The key identifying features of social networks are the users and their connections (Howard 2008; Oinas-Kukkonen et al. 2010). These connections make the structure of the network. While not without their inherent problems, as noted by Batool and Niazi (Batool and Niazi 2014), structural and topological characteristics have been used in various studies to understand the nuances of human behavior in social networks (Shapiro and Varian 2013). Online social network sites can also be analyzed in detail by applying social network analysis (Bonchi et al. 2011).  Previous researchers have found many similarities between offline and online social networks. E.g.  both  type of networks can be scale-free and, at times, some of them can also follow the power law distribution (Chun et al. 2008). Several measures have been suggested yet to analyze the structural characteristics of the network. One of these is commonly known as the centrality measures (Hanneman et al. 2001). The centrality measures are important because they tell us about the most influential and powerful node in the network. Many centrality measures have been proposed yet; the most famous ones are degree centrality, closeness centrality, eccentricity and betweenness centrality (Hanneman and Riddle 2005). The fifth, most popular one is eigenvector centrality measure which has been proposed by Bonacich (Bonacich 1972). This centrality measure are usually used to find the most influential person in the network. Still researchers have noted that using these measures mechanically may not be the most effective means of understanding the interaction structure of the social network (Batool and Niazi 2014).

There are numerous studies that have been conducted to understand the social influences on behaviors of people by using social network analysis (Goyal et al. 2010; Blansky et al. 2013; Hill et al. 2010; Christakis and Fowler 2007; Christakis and Fowler 2008; Mednick et al. 2010). However, the goal of this work is to propose a novel software requirements elicitation methodology involving the analysis of human interactions for use in designing online social network software. Using a network of 498 girls living in a university hostel, we have analyzed the role of the strength of friendship  relationship (for example best friend, friend and acquaintance) besides their everyday life habits (1) whether strength of relationship with different friends affects their sleeping habit (2) whether a girl’s eating habits are associated with her social contacts (3) whether girls take influence of each other while doing exercise or not. We believe that the conducting of social network modeling and analysis has allowed for a better understanding of the hidden behaviors of the large-scale group.

This design methodology gives us the idea to understand human aspects for online social networks by using social network analysis.

The outline of the rest of the paper is as follows: we first present background related to the failure of online social networks or SNS. In the methodology section, we give the details of the proposed design methodology. We also present the social network analysis techniques used.  In the results section, we discuss the analysis results and a detailed discussion on the implications of this proposed design methodology to understand human aspects for online social networks by using social network analysis (SNA).

Failure and Timeline of Online Social Network Sites

Here, we present the timeline and failures of online SNS.

Six Degree

It was founded by Andrew Weinreich in 1997 (New York) by using the concept of six degrees of separation. In few years, this Six Degree attracted almost 1 million users (Heidemann et al. 2010; Hanneman and Riddle 2005).

Failure of Six Degree

But within 3 years, this site had to face failure due to poorly developed web technology (Mednick et al. 2010) whereas the founder of this site had accepted this failure with the statement “It was simply ahead of its time” (Ellison et al. 2007). Despite the failure, six degree has proved as a trendsetter for  future online SNS.

Live Journal

Live Journal was a SNS based in San Francisco California. It was founded by Brad Fitzpatrick in April 1999. By using this site, users were able to keep a diary, a blog, or a journal with another blogging company. In 2007, six apart sold Live Journal to another Russian company. In 2009, they laid off some employees and moved product development and design to Russia.

Failure of Live Journal

In 2007, 2010, and 2012 this site was  blocked by different countries due to several issues such as extremist propaganda perpetuated in its blogs etc (Ellison 2007).

Ethnic sites

In the following years, many other online sites had been launched such as Asian Avenue, Mi Gente, and Black Planet. These can be classified as ethnic community sites.

Failure of ethnic sites

These sites had tried to fill the gap of technical functionality but they also failed  in a few years possibly due to limited friendship  options. Limited options did not allow users to connect with the maximum possible nodes. This way, the question of better designing of social network sites still remained unsolved (Ellison 2007).


In 2001 (San Francisco) Adrian Scott founded Ryze as a business network. Ryze can therefore be considered to serve as a trendsetter and an example model for future business networks (e.g., Linked In).

Failure of Ryze

Ryze too had to shut down  in a few years. To the best of our knowledge, the exact reasons  of the failure of this site are still unidentified (Ellison 2007).


In 2002, Jonathan Abrams founded “Friendster”—primarily as a competitor to online dating sites. It was created on the assumption that  friends of friends would make better romantic partners (Boyd 2004). Friendster allowed the access to the profiles within 4 degrees of separation (Boyd and Heer 2006). Till 2004, Friendster enjoyed considerable popularity and was possibly the biggest site of its time.

In 2011, Friendster was relaunched and a number of registered users reached over 115 million. In 2012, it remained notably popular in Indonesia. In 2015, Friendster finally suspended their services.

Failure of Friendster

Due to its extremely popular nature, the site began to face technical and social issues. These problems included unscalability in part due to servers and databases not being able to handle the interactions of such a large group of people. Secondly, people often ending up a social dilemma by having to deal with undesired contacts. Furthermore, fake users started to become a part of the system, thereby becoming a viable threat to the  privacy of the users. In the  meanwhile, expulsion of a group from Friendster for not complying with the regulations resulted in a chain reaction that ended in a large departure of end-users  (Ellison et al. 2007).


In 2003, MySpace was launched in California. It was able to attract frustrated Friendster users. At the start, music bands from the Los Angeles started using MySpace for advertising VIP passes for popular clubs. MySpace put in a better effort by continuously adding features based on users demand (Ellison 2007). It also allowed users to personalize their pages.

Failure of MySpace

In 2005, News Corporation bought MySpace for $580 million but later sold it for $35 million. The reported reason for this loss was issues pertaining to safety such as sexual interactions between adults and minors. Although some researchers reported it as an exaggerated reason (Boyd and Heer 2006), the end result was a complete failure.

After gathering all the identified reasons of the failures of online social network sites, we propose the idea of modifying traditional methods of software requirements elicitation by the addition of social network modeling and analysis of the expected group of end users.

Previous Offline Behavioral Studies

In the past, social network analysis has been enormously used to analyze the behavioral influence and the spread of habits or information across the network. Christakis et al. (2011) have widely presented their research over the spread of behavior across the networks by using social network analysis and statistical analysis. Specifically they have observed the spread of obesity (Christakis and Fowler 2007), spread of happiness in human society (Fowler et al. 2009), diffusion of emotional states either positive or negative (Hill et al. 2010), social contagion of sleep behavior and drug use behavior (Mednick et al. 2010), spread of smoking behavior (Christakis and Fowler 2008), spread of alcohol consumption (Rosenquist et al. 2010) etc. In all these studies they have taken a large social network of people and applied centrality measures and statistical analysis such as logistic regression and generalized estimation equation (GEE) procedures on longitudinal data. In all these studies they have focused on the spread of behavior.

To analyze the spread of academic success, Hiroki Sayama (Blansky et al. 2013) has also used social network analysis, linear regression, and correlation and observed the relatively higher influence of intermediate level friendship for the spread of academic success in school students.

Use of Behaviorial influence in the Proposed Approach

We have used the approach of analyzing behavioral influences in offline social networks to identify the hidden requirements of a person representing a specific social domain or society. As we have discussed earlier that targeting each individual for requirement elicitation in online social networks (OSN) is impossible. The approach of analyzing behavioral influences suggest the idea of taking requirements from an influential person (who can be identified by using centrality measure) who can possibly influence his/her contacts or befriend similar people regarding their choices and interests. In this way, we can analyze the software design requirements of the society by targeting minimum people.

Proposed design methodology

This section introduces the set of activities related to the design of online social network software.

The proposed design methodology for online social network software is based on the concept of a traditional method of software development design process. Our idea encapsulates the traditional method of software development in addition to  social network analysis of human aspects.

The methodology diagram Fig. 2 represents several phases of the development of online social network software design.
Fig. 2

Proposed design methodology diagram, the proposed idea encapsulates the traditional software development processes in addition with social network analysis of human aspects

  1. 1.

    The first activity of the proposed design methodology takes the social network analysis of human aspects into account.

  2. 2.

    Once the network analysis is performed, identification of influential people is the next task.

  3. 3.

    After finding influential people, the process of requirement engineering would be performed. Requirements gathering from the influential people of the society or that specific social domain would be performed. After requirements gathering, requirements would be analyzed.

  4. 4.

    After requirement engineering process, design phase will start.

  5. 5.

    After the design phase of online social network software, implementation, testing, version release, software validation processes would be performed.

  6. 6.

    In software validation process, the software would be validated against our identified influential people’s requirements.



Source data

All the data was obtained from the girl’s hostel of International Islamic University, Islamabad by developing the questionnaire related to their choices. Girls were asked to list their three best friends and rate them, according to the strength of the relationship. Girls freely recalled their friends and listed their names. We targeted their friends and collected their data. For this purpose, we delivered 600 Questionnaires in the hostels of International Islamic University Hostels and got almost 498 responses.

Social network analysis

The diagram in Fig. 3 presents the sequence of techniques of SNA performed to understand the human behaviors and their influence.
Fig. 3

Social network analysis techniques, the diagram presents the sequence of the network analysis techniques we have performed to conduct the study. First of all the data was gathered and then a network was generated for the analysis. Centrality measures have been calculated to find the prominent actors in the network. After analyzing prominent actors, statistical analysis was conducted in order to validate the results of social network analysis

  1. 1.

    At the first step of our case study, we design a survey in order to collect data. We target 600 people and get 498 responses.

  2. 2.

    After data collection, we first generate a network of friends and represented friends as “nodes” in the network and their relationship as “edges” (directed links) and then manipulate it by deletion of unnecessary nodes (nodes representing girls having no friends), insertion of necessary nodes (targeting missing friends whose presence are necessary to establish the links between friends in the network) and then develop a social network ready for the network analysis.

  3. 3.

    Next, we apply visualization and social network analysis on the network.

  4. 4.

    We also measure centralities in order to identify the prominent actors and their positions. We have also observed the power law behavior of these centrality measures. After performing centrality based analysis on the whole network, we find a unique node in the network which we have termed as the focal node in our study. This node can be considered as the most influential node having highest eigenvector centrality. Then we extract a cluster of the most influential node and her neighbors (friends) located at the one degree of separation.

  5. 5.

    In the end, we have performed statistical analysis to validate the behavioral influence of a focal node in a real life.


The main idea of this study design is to understand the behavioral influence and interests of people for better software requirements.

Methodology used for analysis of social network

First of all, the social network of friends is developed. The main components of the network are friends and their links as nodes and edges respectively. Attributes of the edges represent the strength of the relationship between friends. The basic idea in this social network analysis is that friends according to their position in the social network take the influence of other friends by whom they are surrounded in a social network. Social network analysis is often referred as a structural analysis because this approach is used for exploring structures of the networks. First of all, we made an analysis of the whole network.

Structural characteristics of the network

In the following section, we have described different structural properties of the network.

Network size

Network size of our network is 498 nodes connected by 1226 edges. To calculate the network size is the first step to analyze any network in order to get interesting structural properties of the network.

Cluster size

A cluster is a group of people who are strongly connected to each other but sparsely connected to the rest of the people, 64 Clusters are observed in the network.


The degree is the number of connections of a node in a network. The average degree of our network is 4.9196, where one node represented the highest degree of 24.

See Fig. 4a for degree partition of a network.
Fig. 4

Network analysis and visualization. a This figure represents specific degree measure of every node such as the nodes with yellow color are labeled with 1 which indicates nodes with 1 degree, the nodes with green color have 2 degree, red have 3, blue have 4, pink have 5, white have 6 and so on. b This figure represents 210 strong components. Digits labeled on the nodes (circles) show the component number. c This figure represents 1 weak component in yellow color. d This figure represents 6 cores in the network, yellow colored nodes belong from core 1, green from core 2, red from core 3, blue from core 4, pink from 5 and white colored nodes represent core 6


Components of a network show the level of connectivity of a network, our data set has 1 Weak and 210 Strong components.

See Fig. 4b for strong components and Fig. 4c for weak components.


Cores are the denser regions of the network. These are helpful in identifying the denser parts of the network. 6 Cores are observed on the network (see Fig. 4d).

These structural properties of the network help us in identifying the denser and strongly connected cluster in the network. In the strongly connected cluster of the nodes (representing people) we can identify friends having strong bonds among friends.

Centrality-based analysis

To measure the location of each actor, these centrality measures are required. Centrality is a metric for one node, whereas centralization metric tells us about the whole network.

Degree centrality

A number of links a node has presents the degree centrality of a node. Directed networks are analyzed by using the metrics of in degree and out degree. In degree is referred as the number of links coming towards nodes. Regarding our friendship network, in degree correlates with the popularity of girl among her friends. Out degree is referred as the number of links going out from the node. In the friendship network out degree correlates with the social nature of the girl in a network.

Degree centrality (Freeman 1979) can be calculated by using Freeman’s formula of Degree centrality:
$$C_{D}(v)=\frac{K_{v}}{n-1}= \sum_{j \in G}\frac{a_{vj}}{n-1}$$
where Kv is the number of connections of a node and n is the total number of nodes in the network.

We found one unique (focal) node in a network having the highest degree of 24.

Betweenness centrality

According to the Freeman’s approach betweenness centrality is defined as the proportion of times that the node acts as a bridge between two different nodes for sending information. So this is the most favored position of the actors in the network. So the actor offering shortest (geodesic) pathway between other pairs of actors tend to have high betweenness centrality (Hanneman and Riddle 2005).

Betweenness centrality can be calculated using the Freeman’s formula:
$$C_{B}(v)=\sum_{s\neq v\neq t}\frac{\delta{st(v)}}{\delta{st}}$$
where δst represents the sum of the shortest path, where "s" and "t" can be considered as two different nodes. δst(v) represents the sum of paths that intersect node v.

Our focal nodes betweenness centrality is 0.05.

Closeness centralization
Closeness centrality referred as how far a node from all other nodes in the network (Hanneman and Riddle 2005). If we consider the distance of node as a farness of the node. The closeness would be “the inverse of the farness”. The less total distance of a node, lesser will be the closeness centrality. A node having low closeness centrality considered to be more central in the network. Closeness centrality can be calculated using the Freeman’s formula:
Here v and t are the nodes.

Our focal node’s closeness centrality is 0.31.

Eigenvector centrality
Bonacich’s eigenvector centrality is used to calculate the centrality of a node as a function of the centrality of its neighbors. Eigenvector centrality focuses on the fact that a node having the connection to high centrality nodes are more important than the node having links with low centrality nodes (Boudin 2013). This is a measure for finding the most influential node in a network.
$$\rightthreetimes \, \text{v} = \text{Av}$$
\(\rightthreetimes\) is constant, v is the eigenvector and A is the adjacency matrix. Highest eigenvector value is 1 in our network and only one unique (focal) node is observed with 1 eigenvector centrality.

After doing this network analysis, we took that unique node as a focal person and analyzed her friends (best friend, friend or just an acquaintance) and their social influence over each other. We used the Kamada–Kwai algorithm to get the clear image of the focal person and her neighboring friends at the one degree of separation.

(Focal person/node is the term, we are using here for the most influential person according to the network analysis report; person with the highest degree and the highest eigenvector centrality).

Statistical analysis

To validate the results of structural analysis of the social network we have performed statistical analysis over attribute data of the nodes. Our goal was to evaluate whether a focal person’s habits are associated with her friends in a real life. To test this hypothesis, we took a cluster of friends and analyzed the habits of the focal person and her friends by using the statistical tool named “R”.

Results and discussion

In the following subsection, results of the study are presented in detail.

Network analysis and visualization

Our complete network consists of 498 nodes with 1226 edges. Figure 4a shows all degree partition of a network. 24 is the highest degree of one unique node and the average degree of a network is calculated as 4.9196.

Figure 4b shows the strong component in the network. The size of the largest strong component of a network is 18 vertices having 3.614 of the total network. We used Kamada–Kwai algorithm for the spatialisation of the network.

Figure 4c shows the weak component consists of a whole network. The size of the weak component is 498 nodes which are 100 % of a whole network.

Figure 4d shows cores of the network. Our network consists of 6 cores.

Centrality based visual analysis

For Centrality based visual analysis, we used Gephi software with “Frutcherman Rheingold layout”. Increasing size of the node correlates with the highest centrality value. Figure 5a shows partition of the network, on the basis of degree. The one having purple color with the biggest size is the focal node having the highest degree in a network. Figure 5b shows the visual display of the ranking (size) of the nodes according to the high betweenness centrality and partitioned (colored) on the basis of degree. Figure 5c shows the ranking (size) of nodes with high closeness centrality. Though the network is partitioned (colored) on the basis of degree. Our focal node in purple color is not showing the high closeness centrality. Figure 5d shows the ranking (size) of the nodes with high eigenvector centrality. Again the network is partitioned (colored) on the basis of degree. Our focal node (purple colored) is showing highest eigenvector centrality value in the network, which is the indication of the most influential node.

Centrality-based visual analysis: focal node is in purple color in all networks, size correlates with centrality measures, whereas colors represent the degrees of the nodes in each network. a The one having purple color with the biggest size are the focal node having the highest degree in a network. b A visual display of the ranking (size) of the nodes with the highest betweenness centrality and partitioned (colored) on the basis of degree. c The ranking (size) of nodes with high closeness centrality. d The ranking (size) of the nodes with high eigenvector centrality

After having the complete report of the network, we started focusing the node having the highest degree and eigenvector centrality. These measures have proved this node as the most influential and popular node (person) in the network. We looked for the neighbors of the focal person located at the one degree of separation. We have extracted the cluster including focal person and her neighboring friends located at the one degree of separation from the entire network using “Pajek software”. We have used Kamada–Kwai algorithm to get the clear image of the neighboring friends and the focal person. Figure 6a, b shows the focal person with her neighbors in the network.

(Focal node is the term, we are using here for the most influential node/person according to the network analysis report; the node with the highest degree and the highest eigenvector centrality).

Focal node and the neighboring nodes in a network

Power law distribution of centrality measures of the focal node and the neighboring nodes

Power Law distributions are typically fitted to empirical data when the frequency of an event varies with the power of some attribute of that event however, Clauset et al. (Clauset, 2009) have noted the problems in fitting these distributions on data. In this case we have seen if the frequency of nodes varies as a power of centrality measures.

These plots in Fig. 7 represent the correlation of centrality metrics and the frequency of nodes in the cluster of the focal node (focal person) and the neighboring nodes (friends) located at one degree of separation.
Fig. 7

Centrality plots. a Our focal node has a maximum degree centrality 24. b Our focal node betweenness centrality is 0.05. c Our focal node’s closeness centrality is 0.31. d Our focal node’s eigenvector centrality is 1

Behavioral analysis results

Statistical analysis over the attribute data of the focal node and her neighboring nodes (friends) is performed to analyze the behavioral influences. We took contact type as a function of different variables such as their sleeping habit, the frequency of physical activity in a week, fast food intake and fresh fruits and juices intake to analyze whether the focal person and her contact type (Best friend, friend, acquaintance) share same interests or not.

Figure 8 show the strip charts of the habits of focal person and her contacts. The goal of statistical analysis of their behavior is to understand either people living in the same community take the influence of their friends or not. Additionally, we have tried to validate our network analysis result which has indicated 1 unique node as the most influential node in the network (which we have termed as the focal node in our study).
Fig. 8

Behavioral analysis using strip chart. a Focal node sleeps 7 h in a day. b Physical activity of a focal node in a week is 0. c Focal node’s fast food intake is 8 times in a week. d Focal node’s intake is 3 times in a week

These results showed a slight similarity in their interests.

“R” statistical tool has been used to perform statistical analysis.


Next generation of social media and understanding of behavioral and cultural motives

Adam Smith in “The theory of Moral Sentiments” noted that to understand the social phenomenon, one must incorporate the multitude of psychological and cultural motives. Pent et al. (Cebrian et al. 2016) in their paper have referred the Smith and suggested that “modeling the observable processes and the underlying motivational dynamics can pay tribute to the Smith’s nuanced understanding of human nature and this way next generation of social media can be designed”.

Manifestation of actual real life personalities in online social networks

Gosling et al. (2011) have stated that how offline personalities reflect in the online social domain. To map out the connection between original personality and online social network behavior, they have presented two studies and examined how real personality traits are expressed in Facebook. Their correlation results showed the number of links between Facebook information and respondents actual personality. So they concluded that social and real personality processes are parallel in virtual and non-virtual environment. They suggested that future research should examine how other processes such as social influence and other aspects of personality (attitude, value etc.) are manifested in virtual and non-virtual environment.

Lately in 2015 (Dunbar et al. 2015), latest research has been conducted on Facebook, twitter, and offline social network data sets. They have found sociological similarities between online and offline environments, as implied by the data. In addition, they have also found similar structural characteristics between offline (non-virtual) and online networks (virtual environments).

In another research Lewis et al. (2012) discussed the problem that, do people pick friends who are similar to them or do they take the influence of their friends over time? By using Facebook activity data of college students they analyzed the choice of students regarding their music and movie interests. They picked the people who were already friends in their real life too. Their finding suggests that friends share their interest not because they influence each other but also because they become friends due to similar nature. They have stated that selection and influence play a very important role in relationships and tastes expressed online not only show their psychological preferences but also their presentation of actual self.

By considering these reported ideas, we have proposed this design methodology involving the social network analysis techniques on the offline social network in order to elicit requirements for designing the online social network software. Similar structural properties of network and psychological preferences of people participating in virtual and non-virtual environments suggests the idea of taking an efficient approach of analyzing real life interests of influential people in order to establish future online social network sites.

If we consider the fact of the success of Facebook, and get back to the history this fact is inevitable that Facebook too was first launched for a specific social domain (Harvard only) and then it became famous worldwide in coming years.

Summary of discussion

From 1997 to 2004, many famous online social networks have been launched and had to face drastic failures. The reasons behind many of these failures have remained unidentified. The solution to these problems needs to be worked on. To the best of our knowledge, no one has tried to analyze the behaviors of people participating in the network before launching the website. All the websites were launched on the trial basis and the fate decided their success and failures.

By considering the failed ideas of taking interviews and online surveys of social networks. The idea of offline social network analysis is proposed in our study. By using this approach, we can elicit requirements for use in the design of social network based software. The main idea is to use SNA to understand the behaviors (in terms of influence) and interests of people for better software requirements. Our goal is to conduct an example case study acts as a baseline for better software design.

In this study, we have performed the social network analysis of the offline network to gather the information about human behaviors and their influence over each person participating in a network. The structural characteristics of the whole network have been studied and then the centrality measures are calculated of the cluster of friends.

By applying these measures and then after statistically analyzing the attribute data of the people under study, we have deduced that social network analysis in combination with statistical analysis techniques is an effective method to analyze the interest of people participating in the large social network. The best implication of this design methodology is to link the behaviors of people to online networks in order to perceive the patterns of basic human interests and behaviors where targeting single human for requirement gathering seems impossible.

This case study is considered as just a proof of analyzing hidden requirements, as a standard practice in software design.


In this paper, we have proposed a design methodology by using social network analysis of human aspects for online social network software.

This methodology presents an idea of analysis of human behaviors, participating in large social networks. We have used the approach of analyzing human choices in offline social networks to identify the hidden requirements of a person representing a specific social domain or society. As we have discussed earlier that targeting each individual for requirement elicitation in OSN is impossible, the proposed approach of analyzing behavioral influences suggests the idea of taking surveys to develop models for analysis using social network methods from the intended group of end users. The presented case study has demonstrated the effectiveness of the proposed approach.
