Available in PDF, EPUB and Kindle. Book excerpt: Social networks exist in many places throughout the world. A typical example of a social network captures a group of human beings and their associated interactions, with vertices representing human beings and links representing human interactions. Most social networks are dynamic, and they grow with both vertices and links. From the perspective of link analysis, link prediction is a fundamental task, because social network growth and development depend heavily on user interactions, and link prediction results can be easily applied to boost user interactions. Also, link prediction has a wide range of applications, such as recommendation systems. In this thesis, our research aims at developing effective link prediction models.In the real world, most social networks are heterogeneous and have various types of links. However, current social network research often treat all links homogeneously. Such a simplification has negative implications for link prediction. Different types of links have different properties. We should be able identify such properties to design distinctive models to predict different links. Also, by identifying link types, we can focus on only those links that are under our interests, and break large social networks into small subnetworks to increase computational efficiency in link prediction. Thus, to facilitate link prediction, and to achieve a deeper understanding of social networks, we also need effective link classification models.To conduct our research for link prediction, we design two recommender systems and test their effectiveness on data from a major U.S. online dating site. Online dating is a fast growing market in recent years, and most sites adopt recommender systems to suggest potential dates. We notice that, for most social networks, new links can be introduced in two ways. First, they can be added when new members join. Second, existing members can establish connections among themselves. As a result, we conduct two distinctive studies. In the first study, we aim to provide reciprocal online dating recommendation for new users. To accomplish this task, we take a hybrid approach. We analyze the preferences of existing users based on their activities, and cluster them into different communities. We then link new users to such communities in a probabilistic way and make recommendations for new users based on activities of communities formed by existing users. Compared with the baseline, our model achieves significant improvements across multiple evaluations. In the second study, we analyze interaction patterns for existing online dating users and design a new collaborative filtering algorithm to make recommendations for them. The algorithm considers both the taste and attractiveness of users. We apply these two considerations to two main design stages of collaborative filtering. When compared against two separate baselines, our algorithm achieves better results in both precision and recall, especially for those reciprocal connections. Because links in online dating networks are homogeneous, we take another dataset for our research of link classification. We conduct a study on a cellphone network, where some of its user pairs are labeled with one of three relationship types. Cellphone networks are some of the largest social networks in the world, and they contain various types of links. To design an effective method of classifying user pairs, we extract three categories of features: network topology, communication, and co-location features. By applying several classification algorithms over these features, we successfully classify three types of links. We also find that communication features are very powerful in identifying family relationship, while co-location features provide best performance in identifying colleague relationships.With this research, we hope to provide some insights about the origin, development, and nature of links in social networks.

Download or read book Temporal Patterns of Communication in Social Networks written by Giovanna Miritello and published by Springer Science & Business Media. This book was released on 2013-04-23 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main interest of this research has been in understanding and characterizing large networks of human interactions as continuously changing objects. In fact, although many real social networks are dynamic networks whose elements and properties continuously change over time, traditional approaches to social network analysis are essentially static, thus neglecting all temporal aspects. Specifically, we have investigated the role that temporal patterns of human interaction play in three main fields of social network analysis and data mining: characterization of time (or attention) allocation in social networks, prediction of link decay/persistence, and information spreading. In order to address this we analyzed large anonymized data sets of phone call communication traces over long periods of time. Access to these observations was granted by Telefonica Research, Spain. The findings that emerge from our research indicate that the observed heterogeneities and correlations of human temporal patterns of interaction significantly affect the traditional view of social networks, shifting from a very steady to a highly complex entity. Since structure and dynamics are tightly coupled, they cannot be disentangled in the analysis and modeling of human behavior, though traditional models seek to do so. Our results impact not only the way in which social network are traditionally characterized, but more importantly also the understanding and modeling phenomena such as group formation, spread of epidemics, and the dissemination of ideas, opinions and information.

Available in PDF, EPUB and Kindle. Book excerpt: Online social networks have already become a bridge connecting our physical daily life with the (web-based) information space. This connection produces a huge volume of data, not only about the information itself, but also about user behavior. The ubiquity of the social Web and the wealth of social data offer us unprecedented opportunities for studying the interaction patterns among users so as to understand the dynamic mechanisms underlying different networks, something that was previously difficult to explore due to the lack of available data. In this book, we present the architecture of the research for social network mining, from a microscopic point of view. We focus on investigating several key issues in social networks. Specifically, we begin with analytics of social interactions between users. The first kinds of questions we try to answer are: What are the fundamental factors that form the different categories of social ties? How have reciprocal relationships been developed from parasocial relationships? How do connected users further form groups? Another theme addressed in this book is the study of social influence. Social influence occurs when one's opinions, emotions, or behaviors are affected by others, intentionally or unintentionally. Considerable research has been conducted to verify the existence of social influence in various networks. However, few literature studies address how to quantify the strength of influence between users from different aspects. In Chapter 4 and in [138], we have studied how to model and predict user behaviors. One fundamental problem is distinguishing the effects of different social factors such as social influence, homophily, and individual's characteristics. We introduce a probabilistic model to address this problem. Finally, we use an academic social network, ArnetMiner, as an example to demonstrate how we apply the introduced technologies for mining real social networks. In this system, we try to mine knowledge from both the informative (publication) network and the social (collaboration) network, and to understand the interaction mechanisms between the two networks. The system has been in operation since 2006 and has already attracted millions of users from more than 220 countries/regions.

This book was released on 2013-03-15 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of social networks was originated in social and business communities. In recent years, social network research has advanced significantly; the development of sophisticated techniques for Social Network Analysis and Mining (SNAM) has been highly influenced by the online social Web sites, email logs, phone logs and instant messaging systems, which are widely analyzed using graph theory and machine learning techniques. People perceive the Web increasingly as a social medium that fosters interaction among people, sharing of experiences and knowledge, group activities, community formation and evolution. This has led to a rising prominence of SNAM in academia, politics, homeland security and business. This follows the pattern of known entities of our society that have evolved into networks in which actors are increasingly dependent on their structural embedding General areas of interest to the book include information science and mathematics, communication studies, business and organizational studies, sociology, psychology, anthropology, applied linguistics, biology and medicine.
Download or read book Interacting with Users in Social Networks written by Krishnan Rajagopalan (S.M.) and published by . This book was released on 2016 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: An agent wants to form a connection with a predetermined set of target users over social media. Because forming a connection is known as "following" in social networks such as Twitter, we refer to this as the follow-back problem. The targets and their friends form a directed graph which we refer to as the "friends graph." The agent's goal is to get the targets to follow it, and it is allowed to interact with the targets and their friends. To understand what features impact the probability of an interaction resulting in a follow-back, we conduct an empirical analysis of several thousand interactions in Twitter. We build a model of the follow-back probabilities based upon this analysis which incorporates features such as the friend and follower count of the target and the neighborhood overlap of the target with the agent. We find optimal policies for simple network topologies such as directed acyclic graphs. For arbitrary directed graphs we develop integer programming heuristics that employ network centrality measures and a graph score we define as the follow-back score. We show that these heuristic policies perform well in simulation on a real Twitter network.
