About my Research

I am a Computer Science Ph.D. student at Cornell University.
Information retrieval, data mining are the areas of my interest.
I work with Carl Lagoze and Prof. John E. Hopcroft.

I am fascinated by the networked nature of today's large-scale data (mostly, textual data for now).
I am trying to leverage on the collective intelligence of people embedded in the local interactions (for example, citation links among research papers, hyperlinks between webpages, internet users' browsing history that connects different movies or products as shown in amazon.com etc) to help the information access easier.
I think there is a great potential in the approach that understands the local (microscopic) interactions of the large-scale system and puts this understanding into a good model (often a mathematical model) and then finds out the meaningful, useful global (macroscopic) information about the system.

In this regard, I have done some research on detecting topics from a linked corpus using the correlation between words and links.
These days, I am working on finding out how ideas flow in research paper collections.

I am (or used to be) also interested in distributed systems, especially peer-to-peer systems.
It might seem "information retrieval" and "peer-to-peer systems" are the areas of computer science that are far apart from each other.
But, I feel that they might benefit from a similar principle, as they both need to deal with a large-scale system.
I have done some work in distributed systems in the past.

In the further past, I have done some work in enhancing the performance of intranet search engine by mining the user's browsing history on the intranet.
