Interactive Information Retrieval with Structured Documents

摘要: In recent years there has been a growing realisation in the IR community that interaction of searchers with information is an indispensable component process. As result, issues relating to interactive have extensively investigated last decade. This research performed context unstructured documents or loosely-defined structure encountered web pages. XML documents, on other hand, define different context, by offering possibility navigating within single document, following links documents. Relatively little work carried out study user systems make use additional features offered documents. part INEX initiative for evaluation retrieval, track focused retrieval since 2004. Here friendly exposition various provided and some new are designed implemented enable access their desired efficient manner. In this entails three levels: query formulation, inspecting result list, examining detail. For suggesting related terms conventional method assist searchers. we investigate derived from two co-occurrence units: elements addition, contextual aspect added facilitate appropriate selection terms. Results showed usefulness what acceptance tool. For classic document such as search engines retrieve whole leave it collect required possibly lengthy text. contrast, element aims at view pointing optimal points document. A number strategies presenting lists. For detail traditionally complete presented searcher here again put effort reach its information. We support table contents along also graphical representations depicting granularity retrieved estimated relevance. was found be very useful details. In order conduct analysis searcher's interaction, visualisation technique based Tree Map developed. It depicts system. browsing identified with help tool. The value comparison between approaches passage system evaluated. The suggests find tasks they locate lot relevant specific rather than full Sections, particular, appear helpful. In provide user-specific support, needs feedback searchers, who turn, reluctant to give explicitly. Therefore, extent the can used relevance predictors. Of five regarded, primarily the reading time predictor. Overall, predictors structured documents seem much weaker case atomic
