A semantic search engine for querying XML data is presented. Here the authors present the role of XML search engine in semantic web based on XML data. Due to the popularity of the XML data format, several languages for querying XML have been developed. While these languages allows querying the content of an XML document, they propose a search engine that has a simple query language, enables keyword search at the granularity of XML elements and is also suitable for a naive user. It returns semantically related document fragments that satisfy the user's query. Indexing techniques and Evaluation algorithm is developed that allows the system to deal with large documents.
