We invite research contributions to the Social Network Analysis and Graph Algorithms track at the 30th edition of the Web Conference series (formerly known as WWW), to be held April 19-23, 2021 in Ljubljana, Slovenia (

Social networks have radically changed the way people produce and consume online information, further lowering the access barrier and enabling new forms of interaction between people, objects, information, and services. The COVID pandemic proved that such interaction can be of crucial importance when personal contacts need to be reduced and people’s movements are restrained. On the other hand, the vast amount of data available from many online agents and sources has created an unprecedented opportunity to address both new and longstanding questions. At the same time, these systems have also become targets of issues related to fraud, privacy, fairness and transparency. The sheer size of data has also created challenges regarding storage, analysis, compression and sensemaking.

We encourage submissions in all areas of graph theory and algorithms, graph mining, and social network analysis; we also welcome works that integrate ideas from data mining, machine learning, social sciences, algorithmics and computer science theory. This track explicitly focuses on the investigation of graph-based techniques for social networks with the aim of developing new theories, models, and algorithms to make these systems more effective and efficient.

Topics include (but are not limited to):

  • Algorithms for Graph Reconstruction, Graph Identification, and Network Inference
  • Algorithms for Graph Representation, Sparsification, Sketching, and Compression
  • Algorithms for Subgraph and Motif Discovery
  • Analysis of Heterogeneous, Signed, Attributed, and Annotated Networks
