My research interests include web mining and internet technology. I am applying these technologies in the context of human-centered systems, such as combinFormation. For example, Google generates search results based on PageRank. The result is that people can usually get more relevant results from Google than from other search engines. My thesis topic will incorporate measures such as PageRank, and recency/frequency to model the spontaneous evolution of personal interests during processes of information discovery. With these mesurements, our system will become more able to effectively generate relevant and interesting information compositions.
