Available in PDF, EPUB and Kindle. Book excerpt: This work presents link prediction similarity measures for social networks that exploit the degree distribution of the networks. In the context of link prediction in dense networks, the text proposes similarity measures based on Markov inequality degree thresholding (MIDTs), which only consider nodes whose degree is above a threshold for a possible link. Also presented are similarity measures based on cliques (CNC, AAC, RAC), which assign extra weight between nodes sharing a greater number of cliques. Additionally, a locally adaptive (LA) similarity measure is proposed that assigns different weights to common nodes based on the degree distribution of the local neighborhood and the degree distribution of the network. In the context of link prediction in dense networks, the text introduces a novel two-phase framework that adds edges to the sparse graph to forma boost graph.

Download or read book Graph Neural Networks Foundations Frontiers and Applications written by Lingfei Wu and published by Springer Nature. This book was released on 2022-01-03 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep Learning models are at the core of artificial intelligence research today. It is well known that deep learning techniques are disruptive for Euclidean data, such as images or sequence data, and not immediately applicable to graph-structured data such as text. This gap has driven a wave of research for deep learning on graphs, including graph representation learning, graph generation, and graph classification. The new neural network architectures on graph-structured data (graph neural networks, GNNs in short) have performed remarkably on these tasks, demonstrated by applications in social networks, bioinformatics, and medical informatics. Despite these successes, GNNs still face many challenges ranging from the foundational methodologies to the theoretical understandings of the power of the graph representation learning. This book provides a comprehensive introduction of GNNs. It first discusses the goals of graph representation learning and then reviews the history, current developments, and future directions of GNNs. The second part presents and reviews fundamental methods and theories concerning GNNs while the third part describes various frontiers that are built on the GNNs. The book concludes with an overview of recent developments in a number of applications using GNNs. This book is suitable for a wide audience including undergraduate and graduate students, postdoctoral researchers, professors and lecturers, as well as industrial and government practitioners who are new to this area or who already have some basic background but want to learn more about advanced and promising techniques and applications.

Download or read book Social Network Analysis written by Sabrine Mallek and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social networks are large structures that depict social linkage between millions of actors. Social network analysis came out as a tool to study and monitor the patterning of such structures. One of the most important challenges in social network analysis is the link prediction problem. Link prediction investigates the potential existence of new associations among unlinked social entities. Most link prediction approaches focus on a single source of information, i.e. network topology (e.g. node neighborhood) assuming social data to be fully trustworthy. Yet, such data are usually noisy, missing and prone to observation errors causing distortions and likely inaccurate results. Thus, this thesis proposes to handle the link prediction problem under uncertainty. First, two new graph-based models for uniplex and multiplex social networks are introduced to address uncertainty in social data. The handled uncertainty appears at the links level and is represented and managed through the belief function theory framework. Next, we present eight link prediction methods using belief functions based on different sources of information in uniplex and multiplex social networks. Our proposals build upon the available information in data about the social network. We combine structural information to social circles information and node attributes along with supervised learning to predict new links. Tests are performed to validate the feasibility and the interest of our link prediction approaches compared to the ones from literature. Obtained results on social data from real-world demonstrate that our proposals are relevant and valid in the link prediction context.

Download or read book Understanding User Interactions Through Link Analysis in Social Networks written by Mo Yu and published by . This book was released on 2017 with total page pages. 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.
