V. Mihajlovic and G. Ramirez and T. Westerveld and D. Hiemstra and H. E. Blok and A. P. de Vries TIJAH Scratches INEX 2005: Vague Element Selection, Image Search, Overlap, and Relevance FeedbackABSTRACT Retrieving information from heterogeneous data sources in a flexible manner and within a single (database) framework is still a challenge. In this paper we present several extensions of our prototype database system TIJAH developed for structured retrieval. The extensions are aimed at modeling vague selection of XML elements and image retrieval. All three levels (conceptual, logical, and physical) of the TIJAH system are enhanced to support the extensions. Additionally, we analyze different ways of removing overlap and explain how structural information can be used for relevance feedback. |
