Today schema matching is a basic problem in almost every data intensive distributed application, namely enterprise information integration, collaborating web services, ontology based agents communication, web catalogue integration and schema based P2P database systems. There has been a plethora of algorithms and techniques researched in schema matching and integration for data interoperability....

The first step in finding an efficient way to solve any difficult problem is making a complete, possibly formal, problem specification. This paper introduces a formal specification for the problem of semantic XML schema matching . Semantic schema matching has been extensively researched, and many matching systems have been developed. However, formal specifications of problems being solved by th...

Recently, schema matching has found considerable interest in both research and practice. Determining matching components of database or XML schemas is needed in many applications, e.g. for E-business and data integration. Various schema matching systems have been developed to solve the problem semi-automatically. While there have been some evaluations, the overall effectiveness of currently ava...

Schema matching is the problem of finding relationships among concepts across heterogeneous data sources that are heterogeneous in format and in structure. Starting from the “hidden meaning” associated with schema labels (i.e. class/attribute names) it is possible to discover relationships among the elements of different schemata. Lexical annotation (i.e. annotation w.r.t. a thesaurus/lexical r...

Schema matching is a key task in several applications such as data integration and ontology engineering. All application fields require the matching of several schemes also known as ”holistic matching”, but the difficulty of the problem spawned much more attention to pairwise schema matching rather than the latter. In this paper, we propose a new approach for holistic matching. We suggest model...
