中文摘要:
      通过推荐技术为企业推荐合作者,在提高技术研发效率方面有着重要的意义。在 5 种 ( 物质扩 散算法、热传导算法、偏热传导算法、混合算法、接受者能力算法 ) 基于二分网络推荐算法的基础上, 本文提出二阶同向资源扩散算法;同时使用 β 来判断对合作者合作倾向。以新能源汽车领域专利权 人推荐为例进行实验,实验结果证明使用二阶资源扩散算法比一阶资源扩散算法推荐效果要好,准确 率最高可达 27.59%,召回率最高可达 30.05%,提升幅度最大可以达到 15.17%,最优 β 表明优先选择 其曾经有过合作关系的专利权人进行合作
英文摘要:
      To recommend suitable collaborators through recommendation has important significance of improving the efficiency and the quality of technology research and development. Based on five different bipartite network recommendation algorithms(diffusion algorithm, heat conduction algorithm, partial heat conduction algorithm, hybrid algorithm, the receiver ability algorithm), this paper proposed a new algorithm hereafter, we call it “the second order resource diffusion algorithm of the same direction” , and this study employed a parameter β to evaluate the tendency of cooperation. We applied this new algorithm in the field of new energy vehicles as an example. The experiment results showed that the performances of this new algorithm are better than the first order resource diffusion algorithm, the precision rate is 27.59%, the recall rate is 30.05%, the highest improvement is 15.17% compared with other algorithms. In addition, the results of optimal β indicated that the patentee are preference of former collaborators.
