An overview is given of natural language processing applications in medicine. An attempt has been made to enumerate the most important and known international projects and to summarize their goals, principles, methods and results. A section is devoted to projects involving the Dutch language. A more general discussion about the two fundamental approaches(More)
We report on an a set of experiments carried out in the context of the Flemish OntoBasis project. Our purpose is to extract semantic relations from text corpora in an unsupervised way and use the output as preprocessed material for the construction of ontologies from scratch. The experiments are evaluated in a quantitative and ”impressionistic” manner. We(More)
Ontologies in current computer science parlance are computer based resources that represent shared conceptualizations for a specific domain. This paper first introduces ontologies in general and subsequently, in particular, shortly outlines the DOGMA ontology leaning approach. The paper also introduces the reader in the field of Knowledge Discovery in Text(More)
This paper starts by giving a short overview of one existing NLP project for the medical sublanguage (1). After having presented our objectives (2), we will describe the Restriction Grammar formalism (3), the datastructure we use for parsing (4) and our parser (5) enhanced with a special control structure (6). An attempt to build a bootstrap dictionary of(More)

Ontologies in current computer science parlance are computer based resources that represent agreed domain semantics. This paper first introduces the DOGMA ontology engineering approach that separates ”atomic” conceptual relations from ”predicative” domain rules. A DOGMA ontology consists of an ontology base that holds sets of intuitive context-specific(More)
