Exponential growth of information in the cyber space alongside rapid advancements in its related technologies has created a new mode of competition between societies to gain information domination in this critical and invaluable space. It has thus become quite critical to all stakeholders to play a leading and dominant role in generation of information and monitoring of voluminous information uploaded to this space. However, to achieve domination in monitoring large amount of information in cyberspace requires real-time monitoring using new techniques and approaches instead of traditional techniques. Concerned with the latter case, we limit our focus in this paper on Web blogs as an important part of the cyber space and propose a novel notification system for quick reporting of changes made to Web blogs. This is achieved by restricting the search for changes to high volumes of Web blogs only to changes to the abstracts of Web blogs derived from Web blogs. We show that this system works favorably compared to systems that require cooperation and synchronization between information providers. Manuscript profile

With the growing popularity of social networks, identifying Profile Cloning Attacks (PCAs) is an important challenge within the scope of privacy in the communications world. Until now, researchers have identified these attacks by using features such as profile information, link information, and interactions information that are based on methods like similarities and network structure. Previously suggested approaches lack specific routine and logic to track an attacker, and begin identifying PCAs with victim direct requests or according to the time of a friend request from an attacker. This research offers a new approach with a total of two major steps. Step one emphasizes that legitimate users are attracted to interactions within their local communities; conversely, attackers are attracted to more dense areas. Step two was designed according to the analysis of the interactive behavior that is obtained from users 'earlier research. With this approach, according to a logic based on network structure, search cloned profiles can be identified. Finally, a list of suspicious nodes to cloned nodes has been introduced with their scores that show the accuracy of selection. During the research, a logical relation between the average degrees of social network graph and the selection of the appropriate suspicious nodes with high priority was extracted. Finally, a general framework is proposed. Manuscript profile

The aim of this study is to investigate the effect of using variety of marketing strategies in social networks to build customers’ trust. Marketing through social networks has made appropriate opportunities for companies to attract more customers. Building customers' trust and attracting the customers can be mentioned as marketing challenges on these networks. So, in order to create competitive advantages, companies need to use appropriate strategies of building trust. The population of this study consists of all Iranian users of social networking sites that affected by companies advertisements. Also the sample size by using snowball sampling method is 446. The research method is descriptive survey research and data collection tool is questionnaire. To test hypotheses the partial least squares (PLS) technique and SmartPLS 3 software has been used. The results show that all four variables include: transactional, relationship, database and knowledge-based marketing strategies in social networks have a significant impact to build customers’ trust. Indeed, transactional strategy has negative impact on trust so the relation between this variable and dependent variable is reverse. knowledge-based marketing strategy has the most positive impact on customers’ trust.

This essay would explore the media dimension of operations of takfiri-terrorist IS group. To do so we will study the discourse making process of IS throughout virtual space and Virtual Networks. This article argues that establishing a discoursive system and articulating ideational concepts that construct the positions of Self and Other and give them a hegemonic status is possible via virtual networks and with enjoying of media ploys. In this regard the main question of this essay is about the evaluation of the level of efficacy of these media arenas for IS and assesing the opportunities or by contrast the threats offered by them for IS’s activism. Our hypothesis is that virtual space is useful for IS and this group thanks to a professional approach to social networks and knowing the function of media, can establish a media terrorism by psychological operation and therefore complete its geopolitics actions.

With the pervasiveness of social networks and the growing information shared on them, users of these networks are exposed to potential threats to data security and privacy. The privacy settings included in these networks do not give users complete control over the management and privatization of access to their shared information by other users. In this article, using the concept of social graph, a new model of user access control was proposed to the user, which allows the expression of privacy policies and more accurate and professional access control in terms of pattern and depth of relationships between users in social networks. In this article, by using the regular index method, indirect relationships among users are examined and analyzed, and more precise policies than previous models are presented. The evaluation of the results showed that for 10 neighbors for each user, the probability accumulation of a qualified path for the first three counter loops is 1, 10.5 and 67.3%, respectively, and finally for the fourth counter it reaches 100%. As the defined counting characteristic increases, the average execution time of the proposed algorithm and previously proposed algorithms increases. However, for the higher limits of the counting characteristic, the proposed algorithm performs better than the previous ones. Manuscript profile

Social network analysis is an important problem that has been attracting a great deal of attention in recent years. Such networks provide users many different applications and features; as a result, they have been mentioned as the most important event of recent decades. Using features that are available in the social networks, first discovering a complete and comprehensive communication should be done. Many methods have been proposed to explore the community, which are community detections through link analysis and nodes content. Most of the research exploring the social communication network only focuses on the one method, while attention to only one of the methods would be a confusion and incomplete exploration. Community detections is generally associated with graph clustering, most clustering methods rely on analyzing links, and no attention to regarding the content that improves the clustering quality. In this paper, to scalable community detections, an integral algorithm is proposed to cluster graphs according to link structure and nodes content, and it aims finding clusters in the groups with similar features. To implement the Integral Algorithm, first a graph is weighted by the algorithm according to the node content, and then network graph is analyzed using Markov Clustering Algorithm, in other word, strong relationships are distinguished from weak ones. Markov Clustering Algorithm is proposed as a Multi-Level one to be scalable. The proposed Integral Algorithm was tested on real datasets, and the effectiveness of the proposed method is evaluated.

Predicting collaboration between two authors, using their research interests, is one of the important issues that could improve the group researches. One type of social networks is the co-authorship network that is one of the most widely used data sets for studying. As a part of recent improvements of research, far much attention is devoted to the computational analysis of these social networks. The dynamics of these networks makes them challenging to study. Link prediction is one of the main problems in social networks analysis. If we represent a social network with a graph, link prediction means predicting edges that will be created between nodes in the future. The output of link prediction algorithms is using in the various areas such as recommender systems. Also, collaboration prediction between two authors using their research interests is one of the issues that improve group researches. There are few studies on link prediction that use content published by nodes for predicting collaboration between them. In this study, a new link prediction algorithm is developed based on the people interests. By extracting fields that authors have worked on them via analyzing papers published by them, this algorithm predicts their communication in future. The results of tests on SID dataset as coauthor dataset show that developed algorithm outperforms all the structure-based link prediction algorithms. Finally, the reasons of algorithm’s efficiency are analyzed and presented Manuscript profile

This paper addresses the community detection problem as one of the significant problems in the field of social network analysis. The goal of the community detection problem is to find sub-graphs of a network where they have high density of within-group connections, while they have a lower density of between-group connections. Due to high practical usage of community detection in scientific fields, many researchers developed different algorithms to meet various scientific requirements. However, single-objective optimization algorithms may fail to detect high quality communities of complex networks. In this paper, a novel multi-objective Multi-agent Optimization Algorithm, named the MAOA is proposed to detect communities of complex networks. The MAOA aims to optimize modularity and community score as objective functions, simultaneously. In the proposed algorithm, each feasible solution is considered as an agent and the MAOA organizes agents in multiple groups. The MAOA uses new search operators based on social, autonomous and self-learning behaviors of agents. Moreover, the MAOA uses the weighted sum method (WSM) in finding the global best agent and leader agent of each group. The Pareto solutions obtained by the MAOA is evaluated in terms of several performance measures. The results of the proposed method are compared with the outputs of three meta-heuristics. Experiments results based on five real-world networks show that the MAOA is more efficient in finding better communities than other methods. Manuscript profile

Social networks with more than a decade of experience in providing services and attracting countless user globally have reached a significant economic profitability. Entrance into the social networking market requires creating an innovative, entrepreneurial and secure environment for business. From the viewpoint of native social networking, in addition to the above requirements, this requires financial and infrastructures support as well as a comprehensive strategy. In Iran, along with the global trend of technology, numerous communication and social networks have been launched, which in most cases, their experience has not been successful. In this paper, by studying successful experiences in this field, the existential and obligatory requirements of the coverage of these networks in the country are determined and successful factors of the social network identified. Finally, based on the results obtained and modeling the successful factors of social networks from the perspective of business and users, the vast challenges of native social networks have been extracted and policies and solutions proposed for each of challenges. Attention to the needs of young people, using existing on-line social network analysis, transparency of related lows and regulations, providing incentive and infrastructure supports, considering criteria and cultural and social norms, innovating in business models and creating free-to-access; are suggested strategies for developing native social networks.

Nima system is an integrated system of foreign exchange transactions. Nima is a platform system that has been designed and implemented with the aim of managing the foreign exchange market. In this system, on the supply side, exporters can sell the currency from their exports, and on the demand side, importers can request to buy foreign currency. Identifying effective actors in each of these markets can have a positive impact on the policies of the main market maker of this system, the central bank.Using social networks analysis (SNA) tools can be a good way to achieve this. Since in these networks each of the actors can only have one of the roles of "buyer" or "seller" and there is only the possibility of trading and communication with the opposite role, these networks can be called bipartite networks. As a result, the usual approaches to identifying effective actors for these networks will not be usable. In contrast to standard approaches, we used a weighted projection algorithm to solve this problem. After projectting each of the two networks of foreign exchange supply and demand, four new networks are created, including the network of seller-exporters, buyer exchange offices, buyer importers, and seller exchange offices. Then We will try to make a method to score and rank the nodes. As a result of the implementation of the algorithm, a ranking was provided for the nodes, based on which the node with the highest rank will be the most important node in our network. Finally, in order to make suggestions to the policymaker, by analyzing the results of the ranking, questions about effective market players were answered. Manuscript profile

Nowadays the network science has been attracted many researchers from a wide variety of different fields and many problems in engineering domains are modelled through social networks measures. One of the most important problems in social networks is the prediction of evolution and structural behavior of the networks that is known as link prediction problem in the related literature. Nowadays people use multiple and different social networks simultaneously and it causes to demonstrate a new domain of research known as heterogenous social networks. There exist a few works on link prediction problem on heterogenous networks. In this paper, first a novel similarity measure for users in heterogenous networks is defined. Then a novel link prediction algorithm is described through a supervised learning approach which is consisted by the generated features from the introduced similarity measures. We employ the standard evaluation criteria for verification of the proposed approach. The comparison of the proposed algorithm to the other well-known earlier works showed that our proposed method has better performance than the other methods based on testing on several network datasets.

Short texts of social media like Twitter provide a lot of information about hot topics and public opinions. For better understanding of such information, topic detection and tracking is essential. In many of the available studies in this field, the number of topics must be specified beforehand and cannot be changed during time. From this perspective, these methods are not suitable for increasing and dynamic data. In addition, non-parametric topic evolution models lack appropriate performance on short texts due to the lack of sufficient data. In this paper, we present a new evolutionary clustering algorithm, which is implicitly inspired by the distance-dependent Chinese Restaurant Process (dd-CRP). In the proposed method, to solve the data sparsity problem, social networking information along with textual similarity has been used to improve the similarity evaluation between the tweets. In addition, in the proposed method, unlike most methods in this field, the number of clusters is calculated automatically. In fact, in this method, the tweets are connected with a probability proportional to their similarity, and a collection of these connections constitutes a topic. To speed up the implementation of the algorithm, we use a cluster-based summarization method. The method is evaluated on a real data set collected over two and a half months from the Twitter social network. Evaluation is performed by clustering the texts and comparing the clusters. The results of the evaluations show that the proposed method has a better coherence compared to other methods, and can be effectively used for topic detection from social media short texts.

Data were collected by a survey method and using a questionnaire tool. The statistical population of the study included citizens over 15 years of age in Tehran who were interviewed using the sample size estimation formula, 600 of them were interviewed using multi-stage stratified sampling. The results, regarding objective dimension, showed that cultural consumption is one of the influential variables in the consumption pattern of Tehran citizens and in addition there is a significant relationship between cultural consumption and the use of virtual social networks. On the other hand, there is a relationship between the use of virtual social networks and the clothing consumption pattern of Tehran citizens. In fact, the use of virtual social networks by Tehran citizens has affected their coverage and how they buy. The results obtained in the mental dimension of the subject under study also indicate that the use of social networks has affected the values and social attitudes of Tehran citizens based on consumerism.

Ecotourism creates special opportunities to identify a wonderful aspect of nature, provides new information for tourists, and improves the living conditions of the host society. Since the Hormuz Island has a great capability in ecotourism, it can attract a large number of eco-tourists. Identifying and analyzing the friendly networks between eco-tourists and local people of Hormuz Island are the main aims of this study to investigate such relationship and their social effects. Upon conducting interviews and completing questionnaires by selected people, the collected data were analyzed using descriptive analysis, network’s analysis, and Visone’s software. Investigating the social relations between eco-tourists and local people showed that the formation of an informal friendly relationship and cooperation between the inhabitants and eco-tourists of Hormuz Island positively influenced ecotourism. Created social networks helped ecotourism continue in Hormuz Island and would have desirable economic and environmental effects for local people and Hormuz Island. This can have positive consequences such as increasing ecotourism development, sustainable ecotourism, and better ecotourism recognition for Hormuz Island inside and outside of Iran.

Tourism will soon become the largest service industry in the world with the help of IT. Social networking platforms, which have become prevalent via mobile data, are valuable tools that contribute to the information and telecommunication technology (ICT). These platforms, which provide interactions and exchanges of various contents among the users, have developed new lifestyles and behavioral models among the tourists. Marketers must enjoy the online social networks and e-tourism to increase their competitiveness, market share, and the generated profit by providing the tourists with some services tailored to their demands. Upon reviewing 100 relevant qualitative and quantitative studies, we used an interpretive structural modeling (ISM) approach to present a model with five primary themes, in order of priority: a major environment, managerial factors, individual factors, group factors, and marketing factors. Through these factors, social networks affected tourists’ behaviors. The model was then tested on Iranian tourists’ behaviors using qualitative and quantitative statistical methods. Results could be used by virtually all marketers and activists in the tourism industry. Manuscript profile

The purpose of embedding social networks, which has recently attracted a lot of attention, is to learn to display in small dimensions for each node in the network while maintaining the structure and characteristics of the network. In this paper, we propose the effect of identifying communities in different situations such as community detection during or before the process of random walking and also the effect of semantic textual information of each node on network embedding. Then two main frameworks have been proposed with community and context aware network embedding and community and semantic feature-oriented network embedding. In this paper, in community and context aware network embedding, the detection of communities before the random walk process, is performed through using the EdMot non-overlapping method and EgoNetSplitter overlapping method. However, in community and semantic feature-oriented network embedding, the recognition of communities during a random walk event is conducted using a Biterm topic model. In all the proposed methods, text analysis is examined and finally, the final display is performed using the Skip-Gram model in the network. Experiments have shown that the methods proposed in this paper work better than the superior network embedding methods such as Deepwalk, CARE, CONE, and COANE and have reached an accuracy of nearly 0.9 and better than other methods in terms of edge prediction criteria in the network.

The aim of this study was to investigate the relationship between religious beliefs and dependence on the use of social networks with the degree of observance and commitment to the Islamic hijab of students of Mohaghegh Ardabili University. The statistical population of this study was undergraduate students in different fields of Mohaghegh Ardabili University of Ardabil in the academic year of 1398. For this purpose, 430 students (307 girls and 123 boys) in different disciplines were selected by stratified and random cluster sampling. Made replied; In this study, structural equation modeling method was used to analyze the data. Findings indicate that the direct effect of religious dimension, emotional dimension, consequential dimension, ritual dimension on students 'observance of Islamic hijab is significant, also the direct effect of dependence on the use of virtual social networks has an effect on students' observance of Islamic hijab. It is worth noting that the dimensions of student religiosity and dependence on the use of virtual social networks in data analysis overlap. In other words, the dimensions of religiosity and dependence on the use of virtual social networks, if together, can have a significant impact on students' observance of the Islamic hijab. Of course, the effect of religiosity dimensions on dependence on the use of virtual social networks is negative and inverse. Manuscript profile

The present article studies, influential academic people in Iran and indicate that the position of influencers in the academic environment has also found its place.To conduct this study, we first investigate the concept of fame culture and then review the relationship between university and influencer culture. The next step is to study the typology of academic influencers in Iran through a literature review, as well as the study of seven professors’ Instagram pages. In general, three general types have been identified. The first category is traditional celebrities, who mostly have a small presence on social networks. The second category is professors-influencers, i.e. those who were born within social networks and whose presence, activity and reputation in the virtual world are greater than in the outside world. The third group has a hybrid identity and has an enriching experience in terms of age, but they are not related to the first group. In other words, they are on the border between the first and the second type, but they have a little bit of their former reputation in the world outside of cyberspace, and they have also created a new position for themselves in social networks.In the comparison between these three types of academics, the major distinctions of academic celebrities as emerging figures will be explained.The professors-influencers are born and live in social networks, they owe their fame to these networks, they establish a more horizontal relationship with their audience, they address a more general population, and they are well aware of the strength of weak ties. And finally, they appear in the role of new intellectual leaders in society. Manuscript profile

Women in relation to the role they play in the family, influence the formation of the identity of next generation;especially due to their role as a mother whom train the children and socializing the future generation. On the other hand, changes that occurred in the world in recent decades have provided opportunities to increase this influence. The main object of current research has been understanding the relationship between the use of virtual social networks and the religiosity of women and girls. A quantitative (survey) method has been applied in this research. The research tool is a questionnaire along with an interview. The statistical population of this research consists of women and girls aged 18 to 65 from the cities of Hamedan, Shar-e-Kurd, Shiraz, Ahvaz, Tehran and Kerman, which was conducted based on the evaluation of the developmental level of the provinces announced by the Management and Planning Organization, as well as, the Internet Penetration Rate. The sample size was 1418 people and themulti-stage sampling method were applied. Findings shows that although social networks have an effect on the religiosity of women and girls of the target community,but the effect coefficients are more on ritual dimensions than on belief dimensions and experiential dimensions of religiosity. Also, finding indicat social networks have some effect on Islamic behavior. Manuscript profile

Community structure is a common and important feature in many complex networks, including bipartite networks. In recent years, community detection has received attention in many fields and many methods have been proposed for this purpose, but the heavy consumption of time in some methods limits their use in large-scale networks. There are methods with lower time complexity, but they are mostly non-deterministic, which greatly reduces their applicability in the real world. The usual approach that is adopted to community detection in bipartite networks is to first construct a unipartite projection of the network and then communities detect in that projection using methods related to unipartite networks, but these projections inherently lose information. In this paper, based on the bipartite modularity measure that quantifies the strength of partitions in bipartite networks and using the HellRank centrality measure, a quick and deterministic method for community detection from bipartite networks directly and without need to projection, proposed. The proposed method is inspired by the voting process in election activities in the social society and simulates it. Manuscript profile

In addition, achieving personality traits based on data obtained from individuals' behavior is a challenging issue. Most people spend most of their time on social media and may engage in behaviors that represent a character in cyberspace. There are many social networks today, one of which is the Telegram social network. Telegram also has a large audience in Iran and people use it to communicate, interact with others, educate, introduce products and so on. This research seeks to find out how a recommendation system can be built based on the personality traits of individuals. For this purpose, the personality of the users of a telegram group is identified using three algorithms, Cosine Similarity, MLP and Bayes, and finally, with the help of a recommending system, telegram channels tailored to each individual's personality are suggested to him.

Social networks have become one of the most important decision-making factors in organizations due to the speed of publishing events and the large amount of information. For this reason, they are one of the most important factors in the decision-making process of information validity. The accuracy, reliability and value of the information are clarified by these networks. For this purpose, it is possible to check the validity of information with the features of these networks at the three levels of user, content and event. Checking the user level is the most reliable level in this field, because a valid user usually publishes valid content. Despite the importance of this topic and the various researches conducted in this field, important components in the process of evaluating the validity of social network information have received less attention. Hence, this research identifies, collects and examines the related components with the narrative method that it does on 30 important and original articles in this field. Usually, the articles in this field are comparable from three dimensions to the description of credit analysis approaches, content topic detection, feature selection methods. Therefore, these dimensions have been investigated and divided. In the end, an initial framework was presented focusing on evaluating the credibility of users as information sources. This article is a suitable guide for calculating the amount of credit of users in the decision-making process. Manuscript profile
