Ontology-driven document enrichment: principles, tools and applications

In this paper, we present an approach to document enrichment, which consist s of developing and integrating formal knowledge models with archives of do cuments, to provide intelligent knowledge retrieval and (possibly) addition al knowledge-intensive services, beyond what is currently available using " standard" information retrieval and search facilities. Our approach is onto logy-driven, in the sense that the construction of the knowledge model is c arried out in a top-down fashion, by populating a given ontology, rather th an in a bottom-up fashion, by annotating a particular document. In this pap er, we give an overview of the approach and we examine the various types of issues (e.g. modelling, organizational and user interface issues) which ne ed to be tackled to effectively deploy our approach in the workplace. In ad dition, we also discuss a number of technologies we have developed to suppo rt ontology-driven document enrichment and we illustrate our ideas in the d omains of electronic news publishing, scholarly discourse and medical guide lines.
