Discovering user groups in professional image search

This study aims at gaining insights into user group identification in professional image search. The user groups are built by analysing the search logs recorded by a commercial picture portal for a sample of 170 users, in conjuction with the users’ occupational and topical profile information, and a topical classification of the available images. Our analysis indicates that the examined groupings are meaningful and that there is variation among the groups in what people searched for and in what people considered relevant.
