Title:        Text Representation, Retrieval, and Understanding with
Knowledge Graphs

Abstract:  Search engines and other information systems have started to
evolve from retrieving documents to providing more intelligent information
access. However, the evolution is still in its infancy due to computers’
limited ability in representing and understanding human language. This talk
will present my work addressing these challenges with knowledge graphs. The
first part is about utilizing entities from knowledge graphs to improve
search. I will discuss how we build better text representations with
entities and how the entity-based text representations improve text
retrieval.  The second part is about better text understanding through
modeling entity salience (importance), as well as how the improved text
understanding helps search under both feature-based and neural ranking
settings. This talk concludes with future directions towards the next
generation of intelligent information systems.

Bio:  Chenyan Xiong is a Ph.D. candidate at Carnegie Mellon University. His
research lies in the intersection of machine learning and information
retrieval. His current research focus is on improving text representation
and understanding in real-world information systems using knowledge graphs
and neural networks. He is a recipient of Allen Institute for Artificial
Intelligence research fellowship.  Besides publishing papers, he also
co-organizes NTCIR WWW Tracks about deep learning for search, the first
SIGIR workshop on knowledge graphs and semantics for text retrieval and
analysis, and a special issue in Information Retrieval Journal about
knowledge graph for IR.
