Configurable meta-search in the job domain

: To aid job seekers searching for job vacancies, we have developed a new configurable meta-search engine for the human resources domain. In this paper we describe the three main components of our meta-search engine – the query interface generator, query dispatcher and information extractor – which collectively support the meta-search engine creation and usage. One of the important challenges in accessing heterogeneous and distributed data via a meta-search engine is schema/data matching and integration. We describe an approach to schema and data integration for meta-search engines that helps to resolve the semantic heterogeneities between different source search engines. Our approach is a hybrid one, in that we use multiple matching criteria and multiple matchers. A domain-specific ontology serves as a global ontology and allows us to resolve semantic heterogeneities by deriving mappings between the source search engine interfaces and the ontology. The mappings are used to generat...
