Using the Global Web as an expertise evidence source
by Pavel Serdyukov, Robin Aly, Djoerd Hiemstra
This is the fourth (and the last) year of the TREC Enterprise Track and the second year the University of Twente submitted runs for the expert finding task. In the methods that were used to produce these runs, we mostly rely on the predicting potential of those expertise evidence sources that are publicly available on the Global Web, but not hosted at the website of the organization under study (CSIRO). This paper describes the follow-up studies complimentary to our recent research that demonstrated how taking the web factor seriously significantly improves the performance of expert finding in the enterprise.
The paper will be presented at the 17th Text Retrieval Conference (TREC), November 19-21, at the United States National Institute of Standards and Technology in Gaithersburg, USA.
