Impact of Semantic Heterogeneity and Federating Databases

The Computer Journal 40(5) 1997 Impact of Semantic Heterogeneity on Federating Databases

The difficult problems in design of systems which facilitate interoperation and mediation among information sources and their consumers arise from the presence of semantic heterogeneity among the schemas and ontologies supporting the different services. The purpose of this paper is to develop a taxonomy of semantic heterogeneity, and to describe, taking the perspective of text databases, the co...

Treatment of Semantic Heterogeneity using Meta-Data Extraction and Query Translation

The project CARMEN (“Content Analysis, Retrieval and Metadata: Effective Networking”) aimed – among other goals – at improving the expansion of searches in bibliographic databases into Internet searches. We pursued a set of different approaches to the treatment of semantic heterogeneity (meta-data extraction, query translation using statistic relations and cross-concordances). This paper descri...

An Intelligent Heterogeneous Autonomous Database Architecture for Semantic Heterogeneity Support·

Semantic heterogeneity in heterogeneous autonomous databases poses problems in instance matches, units conversion (value interpretation), contextual and structural mismatches, etc. In this work we examine some of the research issues in semantic heterogeneity and propose a novel architecture for resolving such problems. The approach involves the use of Artificial Intelligence tools and technique...
