Diversity in Expert Search
When Web search engines deal with a broad or ambiguous search query from a user, it is often better to try to present in the results documents matching various aspects of the query to increase the user satisfaction. Is this practice specific to Web search, or can it be applied to expert search as well?
When a user has a technological or scientific need and searches for experts, there are several aspects in which diversification of results can be useful. First, the need may be ambiguous or related to more than one scientific discipline. Hence, the expert search engine must ensure that the related disciplines are represented in the results. Second, a user may be searching for experts in a broad geographic region. Consequently, geographic diversity can be achieved by matching experts from several organizations and institutes. Third, a user may be looking for experts that are more likely to collaborate with the industry. Such experts are more likely to have patents, so the expert search engine must weigh accordingly such evidence in addition to mentions on academic Web sites or scientific publications when ranking experts.
