ABSTRACT A method for determining the degree to which two or more lexical items belonging to a predefined corpus of text in any given language are semantically related to each other, comprising the following steps: a) the retrieval from the said text corpus of a set of sentences in which one or more of the given two or more lexical items appear, b) the parsing, with the aid of a suitable parsing system, of each of the sentences retrieved, in order to determine the syntactic dependency structure of each of the said sentences, c) for each sentence retrieved, determining from the obtained syntactic dependency structure the contextual relations which the given lexical items have in that sentence, i.e. identifying those items in the context which have a syntactic relation to those of the given lexical items which appear in the sentence concerned, together with the syntactic relations involved, d) determining, for each of the given lexical items, the total number of contextual relations found in step c), e) determining the number of contextual relations which the given lexical items have in common, f) determining, on the basis of the results obtained in steps d) and e), the degree of overlap between the contextual patterns of the given two or more lexical items.
