Information Retrieval Methods for Literary Texts

Information retrieval focuses on content-based searching in text documents. For this purpose, first text content must be represented, by using a representation language (like thesauri or classification schemes) or by performing free-text search. The latter approach uses either string-based or computer-linguistic methods (stemming, dictionary lookup, syntax analysis). For retrieval, weighting and ranking methods give better results than Boolean retrieval, and some of them also allow for relevance feedback. Retrieval of XML documents requires new methods for support weighting and ranking, specificity-oriented search, data types with vague predicates and vague structural conditions
