摘要
当今社会,人们越来越多地通过社交网络来发言、聊天、交友。在互动过程中,除了用户主动关注感兴趣的人之外,社交网络也会为其推荐朋友。然而,所推荐的朋友大部分只是社交网络的推广,不一定符合用户的兴趣。针对社交网络推荐朋友的随机性和不可靠等问题,研究并提出了一种基于用户兴趣标签匹配的高效朋友推荐方案。首先,通过Word2Vec来训练语料库中的关键词,得到每个关键词的向量,产生一个词向量空间。其次,利用余弦相似度技术计算关键词之间的相似度并通过实验进行比较。实验中,综合选取合适的相似度值作为两个词向量是否相似的判断阈值。最后,将选取的相似度阈值应用到所提出的朋友兴趣匹配推荐算法中,并进行性能测试和各方案的仿真比较。结果表明,所提出的方案可靠且准确。
With the rapid development of modern network technology,human society has entered the era of information.An increasing number of people prefer to talk and make friends with others through social networks.Besides the people or events which users initiatively focus on,social network will also recommend alternative users.However,most of the alternative users are the promotion of social networks.In this paper,for the accuracy and reliability of social networks recommendation,a new scheme based on tag matching was proposed.First,each word in the corpus is trained by Word2 Vec,and then a word vectors space can be obtained and the similarity among words can be obtained by using the cosine similarity.Secondly,through the similarity comparison experiments,this paper chose an appropriate similarity value as the threshold to judge whether two words are similar.Finally,the similarity threshold was applied to the matching algorithm.The simulation experiments show that the recommend users are relatively reliable and accurate.
