XML Schema Matching – Using Structural Information

نویسنده

چکیده

Schema matching is the task of finding semantic correspondences between elements of two schemas. It takes two schemas as input and returns a mapping that identifies corresponding elements in the two schemas. Schema matching is an important and vital step in many schema and data translation and integration applications, such as integration of web data sources, data warehousing, XML message mapping etc. In this paper, we describe different characteristics exhibited by matching element pairs at various levels in the XML schema and propose a system which uses these characteristics to perform the matching process. The novelty in the system is the architecture of the system which comprises of a linguistic matcher in combination with a set of filters operating based on the level of the element pairs to be matched in the source and target XML schemas.

On a method for XML Schema matching

In this paper a schema is represented using schema trees. Structural matching is performed by matching the local vicinity of each vertex in a schema tree to the vicinity of each vertex in another schema tree using edit distance. A simulated authority is used to determine the quality of the matches by the matcher. The results show that structure indeed plays a role in matching and demonstrate th...

The Essence of XML (Preliminary Version)

The World-Wide Web Consortium (W3C) promotes XML and related standards, including XML Schema, XQuery, and XPath. This paper describes a formalization XML Schema. A formal semantics based on these ideas is part of the official XQuery and XPath specification, one of the first uses of formal methods by a standards body. XML Schema features both named and structural types, with structure based on t...

Resolving Structural Conflicts in the Integration of XML Schemas: A Semantic Approach

While the Internet has facilitated access to information sources, the task of scalable integration of these heterogeneous data sources remains a challenge. The adoption of the eXtensible Markup Language (XML) as the standard for data representation and exchange has led to an increasing number of XML data sources, both native and non-native. Recent integration work has mainly focused on developi...
