摘要
为了在网络社区中监督和提高产品概念设计方案的质量,提出了一种改进的基于云模型的链式推荐算法。该算法对网络社区中的用户数据进行预处理,基于集合信任度和相似度推荐一位候选设计专家;应用链式推荐方式推荐另外二位候选设计专家,扩大了推荐范围;进一步利用云模型的信任云逆向生成器计算三位候选者的全局信任度,得到候选设计专家的全局信任度,信任度最大者即是要推荐的设计专家。实验结果验证了该算法的可行性和有效性。
In order to monitor and improve the quality of the product concept design solution in the network community,an improved chain recommendation algorithm based on cloud model is proposed. This algorithm preprocesses the user’s data in network community,and uses the trust degree of sets and similarity to recommend a candidate design expert. The chain recommendation method is used to recommend another two candidate design experts. The algorithm obtains the global trust degrees of the three candidates by backward cloud generator,and the candidate whose trust degree is the largest is the recommended design expert. The experimental results show the feasibility and effectiveness of the algorithm.
