An 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 کاملFormalizing the XML Schema Matching Problem as a Constraint Optimization Problem
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...
متن کاملUnderstanding The Schema Matching Problem
Schema matching plays the central role in many applications that require interoperability between heterogeneous data sources. The best way to attain comprehensive understanding of the schema matching problem is to construct a complete, if possible, problem formulation. Schema matching has been intensively researched and many matching systems have been developed. However, specifications of the s...
متن کاملFuzzy Constraint-based Schema Matching Formulation
The deep Web has many challenges to be solved. Among them is schema matching. In this paper, we build a conceptual connection between the schema matching problem SMP and the fuzzy constraint optimization problem FCOP. In particular, we propose the use of the fuzzy constraint optimization problem as a framework to model and formalize the schema matching problem. By formalizing the SMP as a FCOP,...
