Ontologies in current computer science parlance are computer based resources that represent agreed domain semantics. Unlike data models, the fundamental asset of ontologies is their relative independence of particular applications, i.e. an ontology consists of relatively generic knowledge that can be reused by different kinds of applications/tasks. The(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)
This paper describes a semantic portal through which knowledge can be gathered, stored, secured and accessed by members of a certain community. In particular, this portal takes into account companies and research institutes participating in the E.U. funded thematic network called OntoWeb. Ontology-based annotation of information is a prerequisite in order(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 on-tology leaning approach. The paper also introduces the reader in the field of Knowledge Discovery in Text(More)

The deliverable D1.2.3 analyses and evaluates existing methods for ontology content evaluation according requirements from an industrial point of view. A classification of methods and tools for the evaluation of ontologies for industrial practice is provided. It concerns methods and tools to:-select existing ontologies (possibly from libraries)-measure the(More)
Ontologies are instruments for capturing and using formal semantics, and are often the result of a "central committee controlled" style of working. A new trend on the Web is the increasing popularity of folksologies in the form of social bookmarking sites. Folksologies provide informal semantics and can be created and adopted by anybody anytime anywhere on(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 on-tology base that holds sets of intuitive context-specific(More)
