We invite research contributions to the Social Network Analysis and Graph Algorithms track at the 31st edition of the Web Conference series (formerly known as WWW), to be held online April 25-29, 2022, hosted by Lyon, France (/www2022/).
Web-based social networks have created new ways for people to interact with each other and produce, consume, and distribute online information. Studying these new types of interactions and data is an unprecedented opportunity to address both new and longstanding questions across and between a number of different fields of research. Due to their societal importance, these systems are now targets of fraud and disinformation campaigns. Moreover, the use of online data from these systems to guide decision-making processes gives rise to many ethical concerns including privacy, fairness, and transparency. The sheer size of data also creates ongoing challenges regarding storage, analysis, compression, and sensemaking.
We encourage submissions in all areas of graph theory and algorithms, graph mining, and social network analysis, and, more broadly, work that integrates ideas from data mining, machine learning, social sciences, and computer science theory. This track explicitly focuses on the investigation of graph-based techniques for social networks and other web data with the goal of developing new theories, models, and algorithms to make these systems more effective and efficient. Specific topics in the space span tasks, ethical impacts of algorithms, emerging data types, and applications.
