PATExpert
Advanced Patent Document Processing Techniques

PATExpert developed a multimedia content representation formalism based on Semantic Web principles for selected technology areas and investigated new generation semantic patent processing techniques.

Impact

PATExpert is about to shift the paradigm for patent documentation processing from textual (viewing patents as text blocks enriched by “canned” picture material, sequences of morpho-syntactic tokens, or collections of syntactic structures) to semantic (viewing patents as multimedia knowledge objects). In the long term, this will essentially change the way patents are authored, filed, stored and processed.

Main innovation

The focus of PATExpert on content (rather than on surface) is expected to lead to a number of innovative technologies in the following areas:

  • Semantic web representation mechanisms for patent material: PATExpert will provide a content and meta-content representation formalism and put it to use by building up knowledge bases (KBs) for two sample patent technology areas: optical recording and machine tools.
  • User-oriented patent classification: For a user, it is essential to be able to define upon the International Patent Classification a dynamic classification schema that is based on his own criteria. PATExpert will facilitate the creation and maintenance of dynamic classification schemas and provide the means for automatic classification of patents in accordance with these schemas.
  • Patent information / and meta-information extraction and (semi-) automatic construction of patent knowledge bases: PATExpert will develop shallow and deep techniques for the distillery of content from patent documentation and its representation in a KB.
  • Semantic multimodal patent retrieval: Along with keyword-based retrieval, PATExpert will work on new generation retrieval techniques that are based on patent text and image similarity, on content, and on meta-information.
  • Patent text paraphrasing: Patent material is very difficult to read due to its very complex linguistic constructions. Shallow and deep techniques for paraphrasing of patent documentation developed in PATExpert will lead to an improved and considerably more readable style.
  • Multilingual patent gist (summary) generation: Users are usually interested in certain specific information contained in a patent (application) rather than in a patent (application) as a whole. The techniques developed in PATExpert will facilitate the generation of concise summaries that contain just the desired information in the preferred language of the user.
  • Intelligent navigation in patent spaces and their visualization: The objects in complex patent representation spaces (be they DBs or KBs) are related by a multitude of different content and meta information links. PATExpert will develop intelligent techniques for visualizing these links and support navigation along them.
  • Patent valuing and technology area assessment: Patent valuing and assessment of technology areas with respect to their potential to give rise to patent applications is a highly demanding issue. PATExpert will contribute to the field by developing techniques that make use of semantic criteria.

 

Results

PATExpert started in February 2006. The first two major tasks consisted in the assessment of the state of the art in all areas of patent processing addressed within PATExpert and the development of the first version of the semantic representation formalism for patent documentation. This formalism forms the foundation of the work on all other topics of PATExpert. In parallel, the first version of the domain ontology for the sample area of optical recording has been developed.

Administrative details

 

  • PATExpert (IST FP6 028116) is a Specific Targeted Research Project under the 4 th call of the European Union's 6th Framework Programme, Thematic Priority 2 (Information Society Technologies), where it addresses the Strategic Objective “Semantic-Based Knowledge Systems”.
  • The project started on 1 February 2006 and finished on 31 July 2008; it involved eight partners from four different European countries.
  • PATExpert's overall budget is about 3.800.000 €
