Information Retrieval
First Claim
1. A method of assisting a user to add a new node to an ontology stored in an ontological database, the method comprising:
- analysing one or more documents and/or groups of documents associated, by the user, with the new node to be added to the ontology, to generate a characteristic vector for the or each associated document or group of documents, performing a classification step using the or each characteristic vector to obtain one or more indications of possibly closely related nodes, identifying the parent node or nodes of at least one or more of the possibly closely related nodes, and presenting the identified parent node or at least one of the identified parent nodes where more than one is identified, for possible selection by the user.

Abstract
Apparatus for assisting a user to add a new node to an ontology stored in an ontological database especially for use in a just in time information retrieval system. The apparatus comprises analysing means for analysing one or more documents and/or groups of documents associated, by the user, with the new node to be added to the ontology, to generate a characteristic vector for the or each associated document or group of documents, preferably using a latent semantic indexing method. The apparatus further includes a classifier for performing a classification step using the or each characteristic vector to obtain one or more indications of possibly closely related nodes and thereby to identify the parent node or nodes of at least one or more of the possibly closely related nodes. Finally, the apparatus further includes display control means for controlling a display to present the identified parent node or at least one of the identified parent nodes where more than one is identified, for possible selection by the user.
