On the other hand manual annotation is both time/money consuming and user-dependent. To address these problems in this paper we present an automatic annotation approach by clustering, in an unsupervised way, clickthrough data of search engines. In particular the query-log and the log of links the users clicked on are analyzed in order to extract and assign keywords to selected content. Content annotation is also accelerated by a carousel-like methodology. The proposed approach is feasible even for large sets of queries and features and theoretical results are verified in a controlled experiment, which shows that the method can effectively annotate multimedia files||URI:||http://ktisis.cut.ac.cy/handle/10488/6873||ISBN:||978-3-642-04276-8 (print)||ISSN:||978-3-642-04277-5 (online)||DOI:||10.1007/978-3-642-04277-5_90||Rights:||© Springer Berlin Heidelberg||Type:||Book Chapter|
