We describe how hierarchical ontologies are used for classifying products, as well as for answering queries. For classifying and scoring product descriptions and queries in an electronic-commerce search engine, we make use of declarative subset/superset and part/whole hierarchies, such as the sense hierarchies provided by WordNet. Retrieval is also aided by use of the ontology. Results of experiments were encouraging.
