متن کاملXML Information Retrieval: An overview
—Locating and distilling the valuable relevant information continued to be the major challenges of Information Retrieval (IR) Systems owing to the explosive growth of online web information. These challenges can be considered the XML Information Retrieval challenges as XML has become a de facto standard over the Web. The research on XML IR starts with the classical IR strategies customized to X...
متن کاملRetrieval Using Structure for Question Answering
This paper examines the use of XML for modern extractionbased question answering (QA). We feel that the XML community has taken too narrow a view of structured retrieval, and that examining specific applications such as QA can give the XML retrieval community a broader view of the problems and challenges that structured retrieval faces. In our examination of QA, we argue that the next steps for...
متن کاملOn Effectiveness Measures and Relevance Functions in Ranking INEX Systems
This paper investigates the effect of performance measures and relevance functions in comparing retrieval systems in INEX, an evaluation forum dedicated to XML retrieval. We focus on two interdependent challenges which arise when evaluating XML retrieval systems, namely weak ordering issue of retrieved lists and multivalued relevance scales. Our analysis provides empirical evidence about the re...
متن کاملThe Importance of Morphological Normalization for XML Retrieval
Current information retrieval systems typically ignore structural aspects of documents, solely focusing on the textual content instead. But documents containing additional structure in the form of HTML, XML, or SGML mark-up are pervasive on the Internet. The XML retrieval task presents a number of challenges for information retrieval, for we can no longer rely on the appropriate unit of retriev...
