CS Colloquium: Xifeng Yan (UC Santa Barbara) - Graph Analysis and Search in Networks

Speaker: Xifeng Yan, University of California at Santa Barbara

Talk Title: Graph Analysis and Search in Networks

Series: CS Colloquium

Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium

In this talk, I will first give an overview about graph data mining and data management studies conducted in my lab and then introduce two projects related to analyzing and searching collaborative and information networks. Collaborative networks are composed of experts who cooperate with each other to complete specific tasks, such as resolving problems reported by customers. We attempt to deduce the cognitive process of task routing and model the decision making of experts. We formalize multiple routing patterns by taking into account both rational and random analysis of tasks, and present a generative model to combine them.

In the second part of my talk, I will show the challenge of querying complex graphs such as knowledge graphs and introduce a novel framework enabling schemaless graph querying (SLQ), where a user need not describe queries precisely as required by SQL. I will also brief our new progress in benchmarking graph queries.

This lecture will be available to stream HERE.
