Abstract:In order to strengthen further scientific of scientific and technical talents evaluation and discovery in the age of big data, it is an evitable trend of scientific and technical talents development and management to establish a quality oriented evaluation and discovery mechanism of scientific and technical talents. Based on the big data of scientific research trajectory of scientific and technical talents in the development, taking quality oriented research theme as clue, the paper has established index system of scientific and technical talents, has proposed fuzzy cognitive discovery method of scientific and technical talents based on big data mining, and has established sharing platform system of scientific and technical talents evaluation and discovery, which help to change existing passive evaluation into active discovery, and modernize scientific and technical talents evaluation and discovery.
