I am a 2nd year PhD student at School of Information Sciences, University of Pittsburgh.
I received both my Master degree and Bachelor degree from Wuhan University. My research interests involve Information Retrieval (especailly for the Expert Retrieval), Topic Modeling,
and Interactive Information Retrieval. A PDF version of CV can be downloaded here.

Working Systems

IRIS-IPS: An Interactive People Search System
Expert finding, collaborator discovery and reviewer finding all can be called people discovery tasks.
They are important because effective handling them requires better fusion of heterogeneous information
resources. However the diverse task objectives and exploratory natures make it very difficult to develop
one algorithm that can maximize multiple objective functions. The novel research goal of this project is
to develop extensible heterogeneous data fusion methods, and design and evaluate interactive people
discovery system to express the exploratory nature of the people discovery tasks and allow users to
specify their task objectives through selecting and adjusting key criteria. This project represents the
first attempt to add transparency and controllability to the discovery process. We are now considering
other tasks such as conference mentor assignment, thesis community member assignment, reviewer suggestion.

Interactive Visualization and Modeling of Latent Communities
In this project, I build a Community Mining & Visualization toolkit.
It has two different algorithms. The first one is a standard community detection algorithm:
the modularity maximization. But I also developed another community detection algorithm that
can show multiple communities belonging.

CollabSearch: Collaborative Information Seeking System
A Collaborative Search System, which can log user behaviors. Behavior such as
chat, comment etc. can be recorded by providing certain functions. Behavior such as web search and query
modification can also be recorded.
