Reasoning & Querying – State of the Art. Keyword-based querying for XML and RDF.
Various query languages for Web and Semantic Web data, both for practical use and as an area of
research in the scientific community, have emerged in recent years. At the same time, the broad
adoption of the internet where keyword search is used in many applications, e.g. search engines, has
familiarized casual users with using keyword queries to retrieve information on the internet. Unlike this
easy-to-use querying, traditional query languages require knowledge of the language itself as well as of
the data to be queried. Keyword-based query languages for XML and RDF bridge the gap between the
two, aiming at enabling simple querying of semi-structured data, which is relevant e.g. in the context
of the emerging Semantic Web. This article presents an overview of the field of keyword querying for
XML and RDF.
