| Abstract: | Publications are most important form of scientific communication, but science also consists of researchers, research projects and organisations. The goal of NARCIS (National Academic Research and Collaboration Information System) is to provide a complete and concise view of current science in the Netherlands. Connecting publications to the researchers, projects and organisations that created them in retrospect is hard, because of a lack in the use of author identifiers in publications and researcher profiles. There is too much data to identify all researchers in NARCIS manually, so an automatic method is needed to assist completing the view of science in the Netherlands. In this thesis the problems that limit automatic connection of author names in publications to researchers are explored and a method to automatically connect publications and researchers is developed and evaluated. Using only the author names themselves finds the correct researcher for around 80% of the author names in an experiment, using two test sets. However, none of the correct matches were given the highest confidence of the returned matches. Over 90% of the correct matches were ranked second by confidence. Other correct matches were ranked lower, and using probabilistic results allows working with the correct results, even if they are not the best match. Many names that should not match, were included in the matches. The matching algorithm can be optimised to assign confidence to matches differently. Including a matching function that compares publication titles and researcher’s project titles did not improve the results, but better results are expected when more context elements are used to assign confidences. |
