ABSTRACT:
The method makes use of a given ontology to select keywords representative of a given document. The method finds all the terms in an ontology that occur in a document, and computes their frequency of occurrences in the document. The method then propagates these values from the leaves upwards to the root of the ontology during which it weights them. The method then selects a subset of terms of the ontology structure as keywords representative of the document based on these weights.
