Abstract
The information processing deviceprocesses document collections having tags permitting semantic class identification appended to each document and comprises a search unit, which creates multiple semantic class units containing one, two, or more semantic classes based on a taxonomy that identifies relationships between semantic classes, and a frequency calculation unitwhich, for each of the semantic class units, identifies documents that match that semantic class unit in the document collections and, for these matching documents, calculates a first frequency that represents the frequency of occurrence in a designated document collection and a second frequency that represents the frequency of occurrence in non-designated document collections. Once the calculations have been performed, the search unitidentifies any of the semantic class units based on the first frequency and the second frequency of the matching documents.
