Window based Enterprise Expert Search

Lu, W., Robertson, S., MacFarlane, A. & Zhao, L. (2007). Window based Enterprise Expert Search. Paper presented at the Fifteenth Text REtrieval Conference (TREC 2006), 14-11-2006 - 17-11-2006, Gaithersburg, Maryland.


This is the first year for the participation of the City University Centre of Interactive System Research (CISR) in the Expert Search Task. In this paper, we describe an expert search experiment based on window-based techniques, that is, we build profile for each expert by using information around the expert’s name and email address in the documents. We then use the traditional IR techniques to search and rank experts. Our experiment is done on Okapi and BM25 is used as the ranking model. Results show that parameter b does have an effect on the retrieval effectiveness and using a smaller value for b produces better results.
