中文摘要：

[目的／意义]针对单学科和双学科主题发现方法无法挖掘现有交叉文献中主题演化来源的问题，提出面向跨学科的主题发现方法，为跨学科发展和合作提供依据。[方法／过程]首先在动物资源与育种领域期刊文献数据中选取已经出现交叉现象的两个基础学科文献及其交叉文献，使用改进的主题相关分析方法，提取共同主题和各自的独立主题；然后利用相关性测度方法量化不同学科独立主题的相关性；最后对共同主题和相似性较高的独立主题进行具体分析。[结果／结论]在动物资源与育种领域的农学生殖生物学、兽医学以及其交叉文献上进行实验验证，结果表明所提出的方法能够有效发现交叉主题的学科出处。

英文摘要：

[ Purpose/significance] This paper aims at the problems of the single and double disciplines topic detec- tion which cannot show the source of topics, proposes a multi-disciplinary topic detection method, and provides the basis for the development and cooperation of the interdisciplinary. [ Method/process ] Firstly, this paper extracts the shared topics and the domain-specific topics from two heterogeneous disciplines and their interdisciplinary using the topic correla- tion analysis method. Secondly, it quantifies the correlation of domain-specific topics using the correlation measures. Fi- nally, the paper analyzes shared topics and similar domain-specific topics. [ Result/conclusion] The experimental results on the agriculture and reproductive biology, the veterinary and the interdisciplinary in the field of the animal resource and breeding show the proposed method effectively detects the source of topics.
