为了揭示文献学术特征与科技查新项目新颖性判断之间的关系,随机抽取54篇农学专业文献和5个农学类课题,由1 0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文献与查新课题的相关性评分,根据评分结果,抽取密切相关文献并作出查新课题相对于文献的新颖性评分,共计900组数据.采用多元回归的方法,研究了学术文献的研究对象、研究内容、研究方法、研究结果的学术特征四要素对科技查新项目新颖性的影响,发现三种不同类型的相关性,得出了一组多元回归模型,进行了检验和分析.

In order to discover the relationship between literature academic characters and the novelty of sci-tech project retrieval, this paper studied the dependence influence between the project novelty of scitech novelty retrieval and the four key academic characters, namely, object, content, method and result. The multiple-regression analysis method, 54 agronomy articles, and five agronomy projects randomly selected were used in this paper.
