Jiawei Han, Michael Aiken Chair Professor in the Department of Computer Science at University of Illinois at Urbana-Champaign.

UNIVERSITY PARK, Pa. Jiawei Han, Michael Aiken Chair Professor in the Department of Computer Science at University of Illinois at Urbana-Champaign, will present a talk as part of the Penn State Center for Socially Responsible Artificial Intelligence Distinguished Lecture Series at 11:30 a.m. on June 14 via Zoom. In the talk, Han will discuss his work to explore the power of taxonomy and embedding in text mining.

About the talk

Real-world big data are largely dynamic, interconnected and unstructured text. It is highly desirable to transform such massive unstructured data into structured knowledge. Many researchers rely on labor-intensive labeling and curation to extract knowledge from text data. Such approaches, unfortunately, may not be scalable, especially when such texts are domain-specific and nonstandard (such as social media). Han and his team envision that massive text data itself may disclose a large body of hidden structures and knowledge. Equipped with domain-independent and domain-dependent knowledge-bases, researchers can explore the power of massive data to transform unstructured data into structured knowledge. In this talk, Han will introduce a set of methods developed recently in his group for such an exploration, including joint spherical text embedding, discriminative topic mining, taxonomy construction, and taxonomy-guided knowledge mining. They show that a data-driven approach could be promising at transforming massive text data into structured knowledge.
