An Algebraic Framework for Schema Matching
It is well known that a formal framework for the schema matching problem (SMP) is important because it facilitates the building of algorithm model and the evaluation of algorithms. An algebraic framework for schema matching is developed in this paper. First, based on universal algebra, we propose a meta-meta structure for schema, which is named multi-labeled schema. This definition has a distin...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
متن کاملA Unified Schema Matching Framework
The proliferation of applications dealing with shared data radically increases the need to identify and discover the semantically corresponding elements. To cope with the difficulties of the necessary schema matching, we propose a unified framework. The framework tries to collect the most well-known work concerning schema matching in a generalized approach. We observe that nearly all of this wo...

متن کاملAn Indexing Structure for Automatic Schema Matching
Querying semantically related data sources depends on the ability to map between their schemas. Unfortunately, in most cases matching between schema is still largely performed manually or semi-automatically. Consequently, the issue of finding semantic mappings became the principal bottleneck in the deployment of the mediation systems in large scale where the number of ontologies and or schemata...
