I am an Associate Professor in the Department of Computing Science, University of Alberta.

My research is on knowledge extraction, data management, information retrieval, and natural language processing. I work on machine learning methods applied to these fields. I have supervised graduate level research on the problems of named entity recognition, typing and disambiguation; open relation extraction; understanding social processes in Wikipedia article authoring; mining citation networks; and semistructured data management.

I am passionate about open linked data and the Semantic Web, and I work with Digital Humanities colleagues on creating, indexing, and processing knowledge graphs out of heritage, cultural, scholarly, and literary work.

I was a founding member and principal investigator of the NSERC Business Intelligence Network, working on information extraction from text.


I teach databases, natural language processing, and information retrieval.


I recently served as associate editor of the IEEE Transactions on Knowledge and Data Engineering (TKDE) and Computational Intelligence.

Occasionally, I serve as a reviewer for ACM Computing Reviews.

My students and I contribute often open source research code. Some recent projects:

  • EXEMPLAR (Relation Extraction)
  • WNED (Named Entity Disambiguation)
  • HRERE (Heterogeneous Representations for Neural Relation Extraction) SOTA as of NAACL 2019
  • NFETC (Neural Fine-Grained Entity Type Classification)
  • PRIMA (IR on the Internet archive)
  • LECTOR+ (information extraction from Wikipedia)
