为了系统、全面、准确的反映动物消化道基因工程研究演进及知识间的联系,本研究以与该专业科研人员互动为基础确定检索式,通过高级检索,采用多元统计、战略坐标、社会网络分析等知识图谱方法,在分时段分析该领域前沿热点特征的同时,增加对该研究密切相关的非热点内容的观察,结果显示:该领域研究热点从个别酶研究开始,进而是一类酶的性质研究,目前的研究热点是纤维素酶类在糖尿病、高雪病等代谢疾病的应用研究,同时观察到2007~2010年该领域研究中罗伊氏乳杆菌Pg4、肉仔鸡、瘤胃微生物、益生菌等一些低频词与β-葡聚糖酶的联系和增长态势.说明精准检索、仔细求证、量化图解分析,热点轨迹跟踪,挖掘隐含信息是科研人员多视角科学观察,准确掌握科研动态,科学决策重要参考依据.%For reflecting relationship between the evolution and knowledge of digestive tract genetic engineering studyof domestic animals systematically, comprehensively and accurately, establishment of the retrieval formula based on the communication and cooperation with the relevant researchers, senior retrieval and the knowledge mapping methods ( multivariate statistics, strategic coordinates, social network analysis and so on) , we analyzed characteristics of advancing front and hot spot in this field at different stage, also increased the observations on non-hot content. The result showed that in this field hot spot began from individual enzyme to a kind of enzyme. The present hot spot is the application of cellulase on metabolic disease, such as diabetes mellitus and Gaucher' s disease. Meanwhile we also found that relationship and increasing tendency between the low-frequency words ( such as Lactobacillus reuteri Pg4 , broilers, rumen microbial and Probiotics) and beta-Glucanase. It was suggested that exact retrieval, careful identification, quantization illustration analysis, hot spot locus accompaniment and implicit information extraction should be important reference for researchers to observe scientifically and multiole-perspectivly, grasp the development of scientific research exactly and make decision scientifically.
