Abstract

A method of performing knowledge extraction from natural language text documents including the steps of reading an input, using semantic based means for extracting concepts and their interrelations from said input text, transforming said input text into a machine understandable knowledge representation so as to provide knowledge libraries from said documents and optionally storing said libraries. The method uses a defined ontology to specify possible semantic relations. Furthermore, the method provides knowledge structures consisting of an arbitrary number of concepts and their interrelations. The method utilises a predetermined mapping between words in the input and concepts and relations in the ontology. These features make a very precise knowledge extraction possible. Thereby, very specific searches can be carried out using the generated knowledge base or library. Additionally, the method is not dependent on the grammatical structures of the sentences in the input text. In that sense, the method for extracting knowledge is language independent.
