Natural Language Processing and XML Retrieval.
Résumé
XML information retrieval (XML-IR) systems respond to user queries with results more specific than documents. XML-IR queries contain both bontent and structural requirements traditionally expressed in a formal language. However, an intuitive alternative is natural language queries (NLQs). Here, we discuss three approaches for handling NLQs in an XML-IR system that are comparable to, and even outperform formal language queries.
