Abstract

This paper describes the details of our participation in expert search task of the TREC 2007 Enterprise track. The presented study demonstrates the predicting potential of the expertise evidence that can be found outside of the organization. We discovered that combining the ranking built solely on the Enterprise data with the Global Web based ranking may produce significant increases in performance. However, our main goal was to explore whether this result can be further improved by using various quality measures to distinguish among web result items. While, indeed, it was beneficial to use some of these measures, especially those measuring relevance of URL strings and titles, it stayed unclear whether they are decisively important.
