Methods for Ontology Design and Ontology-driven Search
(partly supported by Estonian Science Fundation under the grant 4705)
The project aims to contribute to the development of methods for the automatic
construction of application domain ontologies.
Our approach is based on automatic construction of domain-specific ontologies
using Natural Language Processing (NLP) and FCA. The method constructs a
formal concept lattice by algorithmic analysis of noun phrase patterns in
domain-specific texts. Noun phrases are extracted from the text by NLP tools.
Resulting set of noun phrases is stored into the database table, which represents
a context for the application domain in the form of binary relationship between
domain-specific texts and noun phrases. FCA makes it possible to construct
a formal concept lattice of the context. Formal concept lattice obtained
is considered as formal domain ontology for given application domain. Architecture
of the prototypical ontology design tool OntoDesign is developed. OntoDesign
is a system for automatically constructing domain ontologies from given domain-specific
texts by using FCA.
