为了揭示文献学术特征与判断科技查新项目的相关文献之间的关系,采用多元回归的方法,随机抽取48篇农学专业文献,由10位查新员分别给出文献与查新课题的学术特征相似性以及与查新课题的相关性评分,研究了学术文献的研究对象、研究内容、研究方法、研究结果等学术特征四要素对科技查新项目文献相关性的影响,发现研究对象、研究内容、研究方法与科技查新项目相关文献判断有较强的线性相关性,其中研究对象、研究内容呈极显著正相关,研究方法呈显著正相关,得出了一组多元回归模型,进行了模型检验和模型预测验证.

In order to discover the relationship between literature academic features and the relevant articles in judging sci-tech novelty retrieval projects, this paper studied the dependence influence between the sci-tech novelty retrieval related literature and the four key academic features, that is the research object, research content, research method and research result. The multiple-regression analysis method and 48 agronomy articles randomly selected were used in this paper. The academic feature similarity and correlation of sci-tech novelty retrieval project in those articles was respectively ...
