[目的/意义]为了揭示当前基础学科知识交叉的不足之处,提出跨领域交叉学科主题研究方法,并将该方法用于动物资源与育种领域的两个基础学科文献及其交叉文献中。[方法/过程]首先,利用主题相关分析图模型方法提取两个基础学科的共同主题和学科独立主题;然后利用相关性测量方法对学科独立主题的相关性进行量化分析;最后,使用隐藏狄利克雷分配图模型方法提取交叉文献主题,并将其作为参照与基础学科的共同主题和高相关性学科独立主题进行了对比分析。[结果/结论]结果表明:该方法可揭示不同程度学科交叉主题,挖掘现有交叉研究的局限之处,为该领域交叉发展提供帮助。
[ Purpoee/Signifieanee ] In order to reveal shortcomings of current basic subjects, this paper introduces an interdisciplinary topic method, and appfies to two fundamental disciplinary and the interdisciplinary literatures in the animal resource and breeding. [Method/Process] First of all, the method uses the Topic Correlation Analysis method to extract the shared topics and independent topics between two basic subjects. Secondly, the method analyzes the correlation of the independent topics with the correlation measures. Thirdly, the method extracts topics of interdisciplinary documents with Latent Dirichilet Analysis method, and gives the contrast analysis between shared topics and high correlated independent topics of basic subjects and topics extracted from interdisciplinary documents. [ Result/Con- dudon] The result shows that the method reveals topics in different degree, mines the limitation of existing disciplinary study, and pro- vides the advice for the development of cross-disciplinary.
