Abstract

We present an account of designing and evaluating a university-wide expert search engine. We performed system-based evaluation to determine the optimal retrieval settings and an extensive user-based evaluation with three different user groups: scientific researchers, students, and outside visitors of the website looking for experts. Our search engine significantly outperformed the old search system in terms of effectiveness, efficiency, and user satisfaction.
