DEU at ImageCLEF 2009 WikipediaMM Task: Experiments with Expansion and Reranking Approaches
نویسندگان
چکیده
This paper describes participation of Dokuz Eylül University to WikipediaMM task at ImageCLEF2009. This year we concentrated on two main topics: First is about expansion of native document, term phrase selection and query expansion processes which is based on WordNet, WSD and WordNet similarity functions. The second is a new reranking approach with Boolean retrieval and CM based clustering. Experimentation shows that reranking generated the best MAP and precision results among all participants in WikipediaMM 2009 task.

متن کاملDCU at WikipediaMM 2009: Document Expansion from Wikipedia Abstracts
In this paper, we describe our participation in the WikipediaMM task at CLEF 2009. Our main efforts concern the expansion of the image metadata from the Wikipedia abstracts collection DBpedia. Since the metadata is short for retrieval by query words, we decided to expand the metadata using a typical query expansion method. In our experiments, we use the Rocchio algorithm for document expansion....
