About me

This is Pu-xuan Yu (in Chinese “余璞轩”). I am a second-year MS/PhD student from the Center for Intelligent Information Retrieval, and College of Information and Computer Sciences at University of Massachusetts Amherst. My advisor is Prof. James Allan.

My research interests lay in the intersection of information retrieval, knowledge discovery, and machine learning.

Most recently, I am focused on (1) entity-related retrieval and extraction from free text and the Web; and (2) cross-lingual information retrieval (CLIR) for low-resource languages.
