Construction of a Matrix "Physical Effects - Technical Functions" on the Base of Patent Corpus Analysis

Authors use physical effects (PE) to synthesize the physical operation principle of a technical system. PEs implements the technical functions (TF) that describe the functional structure of the declared technical system. The method finds out relationships between physical effects and technical functions performed by them based on the construction of term-document matrices and the search for hidden dependencies in them. To this end, the authors developed a method for extracting descriptions of physical effects from patents in USPTO and RosPatent databases, as well as a method for extracting technical functions from the natural language texts of the same documents. The developed software has been tested for the tasks of extracting physical effects and technical functions from patent documents.
