Research On Model Of Tacit Knowledge Discovery Based On Knowledge Map Under The Environment Of Linked Data

With the development of information technology, the data on the network showing explosive growth. One can easily get a lot of data, but the knowledge is very difficult to be gained from the data. The existing statistical analysis and retrieval tools have been far from satisfying the needs of people in seeking knowledge. In particular, the tacit knowledge discovery is more difficult. The current study focused on knowledge discovery from explicit knowledge or be found to acquire new knowledge model, although tacit knowledge discovery research has begun to address, but the effect is not obvious.Further development of theory of linked data and knowledge map has provided a new way. Linked data provides a possibility for tacit knowledge while knowledge map theory and technology provides theoretical and technical foundation for tacit knowledge discovery. In combination with the four cardinal principles of Linked Data, by analyzing the data model of linked data, extensive links, and data self-describing to elaborated on the role of linked data on tacit knowledge discovery. By analyzing the knowledge content and the relationship of knowledge map to describe the role on tacit knowledge discovery. The following paper presents the research on model of tacit knowledge discovery based on knowledge map under the environment of linked data is based on general rules of tacit knowledge discovery, introducing the theories and technologies of linked data and knowledge map to visual representation of new knowledge to achieve tacit knowledge discovery ultimately.First, based on the clarity of tacit knowledge, linked data, related concepts of knowledge maps, this thesis analyzes the function of linked data and knowledge map in tacit knowledge discovery in a further way. Then, this thesis analyzes and summarizes the discovery processes of traditional knowledge and explores disadvantages and then put forward the discovery pattern of tacit information based on knowledge map under current background of linked data. This pattern can be divided into four modules which are linked data module, data processing module, knowledge map module based on linked data and tacit knowledge discovery module. This thesis gives a further discussion of technologies and theories needed by these four modules, In the last part, the thesis uses DASP which is a knowledge map system based on linked data, to verify and support tacit knowledge discovery pattern put forward in this thesis.
