Abstract
A computer search involves expanding a user query with two synonym dictionaries--actions and object--and then validating the expanded queries by comparison with entries in a Subject-Action-Object Knowledge Database (SAO KB) in a discipline corresponding to the query. The latter is prepared from natural language texts and contains fields with subjects, actions, objects, and 'main parts of objects' extracted from the object.
