Entity Matching across Heterogeneous Sources
Given an entity in a source domain, finding its matched entities from another (target) domain is an important task in many applications. Traditionally, the problem was usually addressed by first extracting major keywords corresponding to the source entity and then query relevant entities from the target domain using those keywords. However, the method would inevitably fails if the two domains h...
متن کاملMatching Attributes across Overlapping Heterogeneous Data Sources Using Mutual Information
Identifying matching attributes across heterogeneous data sources is a critical and time-consuming step in integrating the data sources. In this paper, the author proposes a method for matching the most frequently encountered types of attributes across overlapping heterogeneous data sources. The author uses mutual information as a unified measure of dependence on various types of attributes. An...
متن کاملSemantic Knowledge Discovery from Heterogeneous Data Sources
Available domain ontologies are increasing over the time. However there is a huge amount of data stored and managed with RDBMS. We propose a method for learning association rules from both sources of knowledge in an integrated way. The extracted patterns can be used for performing: data analysis, knowledge completion, ontology refinement.
متن کاملSemantic Integration of XML Heterogeneous Data Sources
With the current explosion of data, retrieving and integrating information from various sources is a critical problem. The designer has to specify a mediated schema providing a homogeneous view on the sources. In this paper, we report on an initial work toward automatically generating mappings between elements in the sources and in the mediated schema. Information sources we are interested in a...
متن کاملA Semantic Matching Approach for Mediating Heterogeneous Sources
Approaches to make multiple sources interoperable were essentially investigated when one are able to resolve a priori the heterogeneity problems. This requires that a global schema must be elaborated or that mappings between local schemas must be established before any query can be posed. The object of this paper is to study to what extend a mediation approach can be envisaged when none of thes...
