Research On Potential Interdisciplinary Cooperative Behavior Based On Literature-based Discovery

Nowadays,social living standards and science and technology are developing very fast,and in this process,there are many increasingly complex problems.But there are different levels of estrangement between different disciplines,and a lot of problems involving more than one discipline,thus it need to break through the limitations of single subject and to comprehensive multidisciplinary knowledge and scholars,so as to solve these complex problems and meet the demand of social development.In the 1920 s,after the word "interdisciplinary" is put forward,interdisciplinary gradually caused the attention of foreign scholars,scientific research has broken the working state,such as the original subject single and differentiation,and a new form of cooperation,the interdisciplinary collaboration,appeared.By the advantage of absorbing knowledge from different disciplines and condensed various thinking modes,interdisciplinary collaboration also got the attention of the scholars in our country,such as scientific research activities by interdisciplinary cooperation and take the interdisciplinary collaboration personnel teaching and training mode,etc.In order to promote interdisciplinary collaboration more widely carried out in our country,promote to solve major social big problems,this article studied from that three aspects: objects and subject of interdisciplinary cooperation and the interdisciplinary collaboration behavior influence factors.First of all,Analyze of Subject Research Hot Spots Based on An Improved Algorithm of TF*IDF.Considering the frequency of subject and the frequency of the text contains this subject,improve traditional TF * IDF method.Through the full text segmentation processing,identifying subject research hotspot.The deep research of hotspot,need the support of interdisciplinary knowledge and methods.So these hotspots are one of interdisciplinary cooperation object.Second,object identification of potential interdisciplinary collaboration behavior based on irrelevant knowledge discovery.Based on the closed and opened relevant knowledge discovery method respectively,through interdisciplinary keywords co-occurrence matrix and distance matrix,defined the keyword two-dimensional vector space model in network,this article puts forward two kinds of interdisciplinary collaboration research topic identification method,and defines the potential research topics of interdisciplinary collaboration cooperation potential index,and certain the research topic as the other interdisciplinary copperation object.Thirdly,based on the author-core keywords network,identify potential interdisciplinary cooperation behavior subject.For the research topic and author that recognized from last two section,build 2-mode network,and define potential interdisciplinary cooperation potential index model and identify the best partners namely is the interdisciplinary cooperation subject,for every research topics in interdisciplinary collaboration.Finally,take the interdisciplinary cooperation subject recognized from the third section as main interview and survey respondents,analyze the factors of interdisciplinary cooperation behavior.Carry on the qualitative research based on innovation diffusion theory and grounded theory to explore the influence factors about interdisciplinary cooperative behavior and the relationship between them.The article found that relative advantage and some other factors has a positive effect on the interdisciplinary collaboration attitude,while complexity etc.have a negative impact.
