Introduction to the Special Issue on XML Retrieval

摘要

With the increased availability of XML documents, the development of appropriate information retrieval methods has recently become an active research area. The explicit representation of the logical structure of XML documents represents a new source of information, which can potentially be exploited by retrieval methods for better information discovery. In addition to structural information, XML tagging is commonly used to indicate semantic information at various levels, from the data type to the role of an element. Novel methods and approaches, which take advantage of the various sources of information are needed. These new XML information retrieval techniques will probably evolve from classical text retrieval as well as from the management of semi-structured data.
