Treatment of Semantic Heterogeneity using Metadata Extraction and Query Translation

Abstract

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 (metadata extraction, query translation using statistic relations and cross-concordances). This paper describes the concepts and implementation of these approaches and the evaluation of the impact for the retrieval result.

The CARMEN Project was funded by the German Federal Ministry of Education and Research in the context of the programme “Global Info”, FKZ 08SFC08 3.
