A Study Semantic Relevance Measurement Of Interdisciplinary In Agricultural Science

At present,with the progress of The Times and the development of science and technology,the trend of interdisciplinary integration is more and more obvious.Research in many fields needs to cross the boundaries of different disciplines and integrate multidisciplinary knowledge and skills to solve complex problems and challenges.The knowledge exchange between different disciplines is becoming more and more frequent.The indepth development of scientific research increasingly needs the collaborative innovation of scholars in different disciplines.In this context,how to measure the intersections of disciplines more accurately and comprehensively,so as to provide reference for interdisciplinary research,is an important topic worth studying.Based on the research status at home and abroad,this paper discusses the concept,influence and measurement index of interdisciplinary correlation.Influenced by the thought of ”five measures”,this paper puts forward the concept of semantic correlation measurement,and uses the correlation data technology to develop the measurement method from the grammar level to the semantic level.On the basis of the discrimination of related concepts and the theoretical basis of information theory,it preliminatively explores the three-dimensional model of interdisciplinary measurement.In order to distinguish the advantages and disadvantages of the methods,on the one hand,the traditional interdisciplinary measurement method is used to extract the subject,cited,keywords,countries,regions,authors,institutions and other title information based on ESI high-impact papers,and the methods of document metrology,network analysis and collection visualization are used to carry out interdisciplinary analysis from multiple dimensions to reveal the interdisciplinary phenomenon.Discover the interdisciplinary characteristics;On the other hand,high-impact papers of agricultural engineering in ESI are taken as samples to conduct empirical research using semantic relevance measurement method.It is found that interdisciplinary is a common phenomenon;There is a certain preference for the cross among disciplines.The degree of cross among different disciplines is different,and the crossing points of different disciplines are also different.Interdisciplinary scale on the whole presents an expanding trend.In the empirical analysis of semantic correlation measurement,on the one hand,correlation data technology can realize interdisciplinary measurement at the semantic level.On the other hand,semantic relevance measurement has some advantages in interdisciplinary measurement.This study provides a new perspective and thought for interdisciplinary research and is of great significance for a comprehensive insight into interdisciplinary integration.
