Meta-data Extraction and Query Translation. Treatment of Semantic Heterogeneity

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 describes the concepts and implementation of this approaches and the evaluation of the impact for the retrieval result.
