基于关键词网络的热点关键词及热点项目挖掘

摘要

针对传统使用频数挖掘热点关键词不能保证有效完整地挖掘出数据库中的热点关键词，提出基于项目、专家对应的关键词数据，分析不同项目关键词之间的相关度，从而建立“项目与专家”网络关系。其创新点在于用双层结构来连接专家、网络、关键词，计算关键词的热度值，挖掘出热点关键词及热点项目。实验结果表明，该方法更能准确地挖掘出项目中的热点关键词，避免了单纯频数计算热点关键词带来的片面化问题。%Traditional method using frequency to mine hot keywords cannot guarantee the effectiveness and integrity of hot keywords mining from database,for this issue,we propose a method which is based on the keywords data corresponding to projects and experts and analyses the correlation between different project keywords so as to establish project-expert network relationship.Its innovation lies in using double-layer structure to connect the experts,the network and the keywords,calculating the hot degree of keywords,so that mines out the hot keywords and hot projects.Experimental results show that the method can more accurately mine the hot keywords in projects,and avoids the one-sided problem brought forth by only using frequency to calculate hot keywords.
