Cooperative institution recommendation method and system based on patent data

Abstract

The invention provides a cooperative institution recommendation method based on patent data, and the method comprises the following steps: a demand data obtaining step: obtaining the demand data of a target enterprise; a target patent data acquisition step: acquiring target patent data according to the demand data; a candidate set construction step: constructing a candidate set based on a cooperation relationship according to the target patent data or constructing a candidate set based on text similarity according to the target patent data; a candidate set optimization step: carrying out optimization sorting on the candidate set according to an inverse distance weight, and obtaining cooperation mechanism data based on distance optimization; and a recommended cooperative mechanism list acquisition step: acquiring a recommended cooperative mechanism list according to the distance-based optimized cooperative mechanism data. In the scene of collaborative filtering recommendation based on the cooperative relationship, the recall effect of recommendation sorting by adding the inverse distance weight is better than the recall effect of recommendation sorting by not adding the inverse distance weight.

Description

technical field [0001] The invention relates to the technical field of personalized recommendation, in particular to a method and system for recommending cooperative institutions based on patent data. Background technique [0002] In such a competitive society, it is difficult for an enterprise to fight alone. It often needs to cooperate with other institutions, such as schools or other enterprises, to improve industrial competitiveness through collaborative innovation. Due to the possible competitive relationship between enterprises and other institutions, and the possible risks of target differences and information asymmetry in the process of cooperation. At present, when enterprises choose cooperative institutions, they choose through the introduction of acquaintances, or based on the reputation of the school in industry-university cooperation. However, in this method of selecting cooperative institutions, there are situations where the capabilities of cooperative institu...

Problems solved by technology

[0003] Based on this, in view of the technical problems that the traditional cooperative institution selection method cannot choose a more suitable cooperative institution due to differences in goals and information asymmetry, and restricts the development of enterprises or the transformation of advanced technologies, a method based on patent data is proposed.
