Method of bibliographic information extraction from full-text descriptions of inventions

The method of bibliographic information extraction from full-text descriptions of inventions, which is necessary for analysis of thematic linkages between science and technologies, is considered. The research objective consists in the development of principles for creation of domestic information systems for calculation of indicators of thematic linkages. This type of information systems is new to the Russian scientific and technical sphere. Their creation is necessary for monitoring and evaluation of research and development programs and decision-making at all stages of program activities. The suggested method of bibliographic information extraction from the texts in natural language differs a lot from available foreign and domestic analogs. First, this method considers the fact that bibliographic information can be found inside the natural language text of descriptions of inventions. Second, paper bibliographic information is the structured information object, which is generally multilingual.
