Research On Resource Aggregation Based On The Taxonomy-folksonomy Hybrid Model In Social Tagging System

Under the environment of Web2.0, users proposes more and more andneeds such as diversification need, professional need, personalized need,humane need and knowledgeable need to access the resources in socialtagging system，so it has become a trend and scientific frontier thatexploring multi-dimensional resource aggregation. We all know it is amulti-value solutions to solve the problem，and construction a tax-folkhybrid model is one solution.When we analyze the current situation of social tagging systemresource aggregation，we can find that scholars and experts from home andabroad has achieved some results and they often focus their research onfour areas：Resources aggregation based on depth semantic in socialtagging system, resources aggregation based on association in socialtagging system, resources aggregation across social tagging systems andresources navigation in social tagging system. Unfortunately, there arestill many unsolved issues to be explored, such as building an excellentsematic architecture is a new-emerging field in it, and the aggregationmechanism of social tagging systems is also required, and the resourceaggregation dimension of social tagging system is imperfect, also theresource aggregation across systems becomes more and more important, andfinally the form of resources navigation needs a diversification change.Resources semantic architecture is the basic and support of resourceaggregation of social tagging system. Through comparative analysis of thedifferentiation and interactivity of the resources semanticrepresentation in current social tagging systems, a new resourcessemantic architecture can be built, which consist of five layers: "resource layer-the symbol layer-knowledge representation layer-mapping layer-logical reasoning layer". With the support of thearchitecture, the aggregation mechanism of social tagging systems can beexplored: all of the semantic representation tools and methods shouldinteract and complete each other in order to achieve the goal of deeplyrevealing the resources’ semantic, while the concept analysis based ondata sets should be actualized using FCA et.al., and ultimately we canget an organic integration of theory, methods and techniques. Buildingthe Tax-folk hybrid model is just the concrete manifestation of thismechanism.Tax-folk hybrid model is derived from the integration of taxonomy andfolksonomy. In an ideal metaphor for the tree of knowledge, its shapeshould be "A tree with strong trunk, luxuriant branches and foliage",while the metaphor of taxonomy should be “A tree with strong trunk andbranches but little foliage”, and the metaphor of folksonomy should be“A tree with weak trunk and branches but luxuriant foliage”, so it isthe right solution of resource aggregation problem that we can graftfolksonomy to taxonomy in order to construct a new tax-folk hybridclassification, and the FCA tools are just like scissors.At the same time, we must also see that although the idea of tax-folkhybrid classification is clear, but its implementation involves manyinteraction factors, including the component elements, role elements andfunctional elements. These elements and the deep relationship among themtogether constitute a tax-folk hybrid model, which give a clear answerabout “what" should the new model do from the macro-level.Further, the specific process of resources aggregation based on theTax-folk hybrid model is the answer about “how”should the new model dofrom the micro-level. Through six key steps, which consist of datapreparation, concept lattice construction, concept lattice analysis, tax-folk mapping, tax-folk hybrid classification tree generation, outputand evaluation, the operations procedures of grafting folksonomy totaxonomy formed a mixed classification can be truly actualized usingformal concept analysis.Select “Douban” as a case analysis object from many social taggingsystems, and select the book resources which called“books read by fiftythousand to one hundred thousand people”as experimental resources, wecan collect relevant data and give an empirical study use the specificprocess of resources aggregation based on the Tax-folk hybrid model, andanalyze the experiment result to proof whether the theory we proposed inthis paper is scientific, reasonable and workable.The research on resource aggregation based on the Tax-folk hybridmodel in social tagging system has new value not only because the newopinion of “ideal resource organization tree” is proposed, and the newways to achieve social tagging system resource aggregation is found byconstructing tax-folk hybrid model, but also because the tax-folk hybridclassification tree formed from the model has very high advantages onresource organization.It has two aspects of significance at least that we do the researchon resource aggregation based on the Tax-folk hybrid model in socialtagging system, on the one hand, there is a theoretical explorationsignificance because the research improves theory architecture ofresource aggregation in social tagging system, and on the other hand,there is a practical significance because the tax-folk hybridclassification improves the resources usage efficiency of social taggingsystem, and thus bring economic and social value.
