Abstract

The Web has driven many developments related to information retrieval in the past 5 years. One of the recent waves is due to XML (eXtensible Markup Language), a meta-language derived from SGML and designed for data representation and exchange on the Internet. XML provides support for marking (tagging) text for many purposes such as structure, semantics, layout, etc. It is believed that it will become a universal format not only for business-to-business applications but also for knowledge and information management. As a result, it has become crucial to address the question of how large collections of XML documents can be sorted and retrieved efficiently and effectively. Furthermore, it is necessary to develop a suitable query language for XML documents. Last year the World Wide Web Consortium released a query language proposal for XML data known as XQuery. XQuery is the combination of many proposals and previous languages, some of which are covered in this issue. XQuery is the natural meeting point of the database and information retrieval communities, because it requires that SQL-like queries as well as text retrieval queries must be answered correctly and efficiently. Hence, having a special issue on XML and information retrieval is timely and almost compulsory.
