Industry standard blank feature recognition system and method based on multi-source data analysis

The invention discloses an industry standard blank feature recognition system based on multi-source data analysis. A database of the industry standard blank feature recognition system obtains a patentand paper high-frequency feature word group set; the technical field division module is used for obtaining technical direction classifications contained in the retrieved patent and paper data; a clustering module acquires a patent and paper high-frequency feature word group set under each technical direction classification; the database obtains an industry standard high-frequency feature word group set under each technical direction classification; and the identification module obtains characteristic word groups which do not belong to the industry standard high-frequency characteristic word group set in the patent and paper high-frequency characteristic word group set under the same technical direction classification. According to the invention, the blank technical feature identificationin the industry standard i
