Tiivistelmä
Numerous XML query languages have been proposed and developed in the recent past to retrieve information from structured and unstructured documents. While these query languages resolve many challenges incurred with the increased use of XML for information processing and storage, there is little emphasis on the result-view provided to the query user for document oriented collection. To overcome this shortcoming, Junkkari et al. [2006] proposed a new query language called XIL (XML information retrieval Language). XIL reconstructs the results for document intensive collections and provides a relevance based view to the query user.
This thesis checks the feasibility of constructing relevance based views using Dewey indices for XIL and further investigates on its design and development. The detailed syntax for XIL is also specified, in EBNF(Extended Backus-Naur Form) notation, as part of this study.
As background research, four existing languages (XPath, XIRQL, XQuery and TeXQuery) were studied for its syntax, features, data model and results shown to the end user. The study concludes by investigating if relevance based views offered by XIL is beneficial from an end user point of view in comparison to these four query languages apart from validating the benefits outlined in XIL.
