Faculty Candidate Talk: AutoNet: Automated Network Construction from Massive Text Corpora

Abstract: 

Mining structured knowledge from massive unstructured text data is a key challenge in data science. In this talk, I will discuss my proposed framework, AutoNet, that transforms unstructured text data into structured heterogeneous information networks, on which actionable knowledge can be further uncovered flexibly and effectively. AutoNet is a data-driven approach using distant supervision instead of human curation and labeling. It consists of four essential steps: (1) quality phrase mining; (2) entity recognition and typing; (3) relation extraction; and (4) taxonomy construction. Along this line, I have developed a number of state-of-the-art distantly-supervised/unsupervised methods and published them in top conferences and journals. Specifically, I will present my work about phrase mining, entity recognition, and taxonomy construction in details, while touching the other work slightly. Finally, I will summarize the AutoNet framework with a demo video and conclude by discussing future work collaborating with other disciplines.
