Distributed Information Retrieval and Applications

چکیده
Distributed Information Retrieval (DIR) is a generic area of research that brings together techniques, such as resource selection and results aggregation, dealing with data that, for organizational or technical reasons, cannot be managed centrally. Existing and potential applications of DIR methods vary from blog retrieval to aggregated search and from multimedia and multilingual retrieval to distributed Web search. In this tutorial we briefly discuss main DIR phases, that are resource description, resource selection, results merging and results presentation. The main focus is made on applications of DIR techniques: blog, expert and desktop search, aggregated search and personal meta-search, multimedia and multilingual retrieval. We also discuss a number of potential applications of DIR techniques, such as distributed Web search, enterprise search and aggregated mobile search.
