Apparatus and method for computing noun similarities using semantic contexts

摘要

A semantic-based noun similarity calculation method according to the present invention comprises: checking a feature vector map for a plurality of adjectives included in each of a plurality of noun phrases extracted from a sentence and a document; generating a plurality of first feature vector sets on the basis of a plurality of nouns included in the each of the plurality of noun phrases; generating a plurality of second feature vector sets based on the feature vector map checking the generated plurality of first feature vector sets; calculating an adjective similarity by using two second feature vector sets for each of two nouns based on the second feature vector sets; and calculating a semantic similarity for the two nouns based on the adjective similarity.
