科技项目评审专家推荐系统模型

针对科技项目评审专家的准确遴选问题，提出一种混合推荐系统模型。该模型在文本信息分词的基础上，运用TF—IDF算法进行关键词的提取、权重计算及筛选，分别建立科技项目和评审专家的向量空间模型，并基于专家信息建立专家评分数学模型。最后提出一种内容推荐、协作过滤推荐及专家评分加权因子相融合的混合推荐算法。实验结果表明，该推荐模型能有效地进行评审专家推荐。

Research of Recommendation System for Technological Project Assessors

Based on the issue of assessors’ selection problem for technological project,this paper proposed a new hybrid recommendation system model,the model extracts keywords with TF-IDF algorithm on the basis of project and experts text information segmentation,then establishes vector space model according to the screened words,and finally proposes a new hybrid recommendation algorithm based on content recommendation which generates screened results with collaborative filtering recommendation and weight coefficient.Experimental results show that the proposed model can accomplish assessors recommendation effectively.
