Research On Digital Library Resources Aggregation Based On SNA

At present, the social economy of our country has been transformed fromtraditional economy to knowledge economy. Knowledge economy is a collection ofinformation industry, communication industry and cultural industry. Digital library asa knowledge of the land is the main infrastructure of knowledge economy andmaterial form and the digital library resource aggregation plays an important role inthe process of knowledge utilization. However, due to the mining and the effectiveuse of collection resources, lack of integrity and systematic research, smartpolymerization of distributed and heterogeneous resources still lacks a reasonablepath, making the rich digital library collection resources not be effectively utilizedand shared with depth. This caused serious waste of resources, thus affecting theutilization rate of resources and the deepening of user retrieval content. Therefore,how to use social network relation between data mining and resources and how tosolve the heterogeneous information resources sharing and intelligent service isbecoming more and more urgent. To supply accurate reliable personalized collectionresources to the users of information and intelligent application service, digital librarycollection resources aggregation becomes the top priority of research.Faced with width to depth development of digital library resources and theassociated application requirements, from the resource characteristics of correlationbetween the angle of view of the process and resource utilization associateddimension,this thesis studied deeply and systematically path,pattern and itsapplication scope and other issues of digital library resources aggregation. Combinedwith the resources in the field of “Library and Information Science”, the integrateduse of social network analysis, matrix algorithm, the network mapping tools, methods,analysis the author coupling relations, the author cooperation relationship, the authorkeywords, according to the relationship between visual network map, argumentationway of digital library resource aggregation is studies, so as to provide implications fortheory research and practice of digital library resource aggregation.According to the route of “find problems, analyze problems, solve the problem”, this article conducted a study of digital library resource aggregation of social network,following the research train of thought of “theory research, model building, empiricalanalysis”. The concrete content includes:（1）Based on the domestic and foreign digital library resource aggregation theoryresearch and the application of SNA method, the related literature summarizes thepoints of view. Through the overview of the research status at home and abroad, thepaper probes into the social network analysis method in the application of theresource characteristics and resource utilization associated process associated. Fromthe comparison of the similarities and differences between domestic and foreignresearch contents and angle, it tries to explore the current research hot spot and theresearch outline. On this basis, through in-depth analysis of the research problems andthe insufficiency of current collection resources aggregation at home and abroad, weproposed in this paper the questions and purpose of the research.（2）The paper revealed the digital library resources aggregation mechanism andmode, based on SNA, and built social network relationships between digital libraryresource aggregation model. Based on the research of the digital library resourceaggregation method, from the level to satisfy user needs, it discussed how to make theseemingly random resources associated. When a user retrieval system can providemore heterogeneous resources according to retrieval condition, it realized theapplication of more intelligent and conceived using social network analysis methodcombined with the feature of internal and external resources. By analyzing thecorrelation between features and association in the process of resource utilization andresource aggregation model, the paper implemented the aggregation of resources ofrelated disciplines. Finally, based on the principle of aggregation, the paper builtcollection resources aggregation model composed of the data layer, analysis layer, theaggregation layer, and application layer.（3）The paper conducted empirical analysis of the digital library resourcesaggregation based on SNA. It did the SNA of literature resources of libraryinformation science mainly from the internal and external literature features, and theangle of the associated utility. It used the citation relationship, the author cooperation relations, the relationship between author keywords co-occurrence based on resourcecharacteristics, such as authors, themes, keywords associated attributes, formed thesocial network between author and keywords, between author mutual quotations, andbetween collaborators. Through the social network visualization display, clear thecore authors, subject matter, research field, potential collaborators and internalpartners, the paper realized resources aggregation of related fields, and provided thehigh quality for the user to retrieve resources. These results provide the reference forthe follow-up related research and provide a broader perspective for the study of thesubject development.
