Abstract: Embodiments of the present invention provide techniques for generating ontologies. In one embodiment, techniques are provided for automatically generating an ontology based upon input information. The input information may, for example, be in the form of XSD, XML, WSDL, or WSRP, etc. The automatically generated ontology may be encoded in OWL or other RDF-compliant language. A set of inference rules may also be automatically generated using the input information. The automatically generated ontology and the set of inference rules may be stored in a database for further processing.

Abstract: Techniques for simplifying querying of ontologies. In one embodiment, one or more queries for querying an ontology are automatically generated in a language suitable for querying the ontology. A user may enter a query in a simple language such as a natural language query. In response, one or more queries capable of querying the ontology are automatically generated in a second language. The automatically generated queries may, for example, be in SPARQL or PL/SQL. The one or more automatically generated queries may then be used to query one or more ontologies.

Abstract: The present invention is directed to methods and systems which provide a comprehensive rating and ranking of products and services. Furthermore, aspects of the present invention provides a complete review of products and services, as well as rankings of semantic and non-semantic reviews, which provides a “true” reflection of a product and/or service. As such, a calculation of a product/supplier rating based on all of its social entity contexts, is performed. This takes into account factors like, author (of social entity context) credibility, non-semantic (direct) rating, semantic rating calculated from the textual content of the social entity context, the community based credibility of the social entity context, and the like. Then, the community based credibility of a given social entity context is in turn calculated.
