Abstract


With the surge of resources and users of scientific literature on the demand of the deep-seated knowledge content , knowledge discovery in the scientific literature collection is on the rise . Literature has semistructured characteristics different from the general database of information resources , the computer is difficult to understand and deal with , must take advantage of the targeted analysis method to obtain a comprehensive and in-depth understanding of the document content . Revealed knowledge associated research unit of knowledge from the literature to deepen to the existing knowledge in the literature associated . Therefore, to explore the theory of knowledge discovery - oriented knowledge associated reveals its application has an extremely important theoretical and practical significance . First , this paper discusses the concept of knowledge discovery , discovery mode , the general process and key technologies , and discussed in - depth knowledge discovery - oriented knowledge associated systematic summary of the scientific literature the knowledge associated definitions , types, and knowledge associated reveals the typical . Secondly , on this basis , respectively, to focus on three types of knowledge associated methods : based on the knowledge associated with citation analysis reveal knowledge relationship based on co-occurrence analysis reveals , based on the knowledge related thematic analysis reveals . Then summed up the knowledge discovery - oriented knowledge associated reveals in the discovery study the application of the various methods on the basis of theoretical research method reveals three types of knowledge associated with case specific analysis of the implementation process and the role of the various methods ; the knowledge structure of the discipline , the research focus as well as evaluating the field of scientific research , researchers , and the strength of research institutions have an important role . The final thesis combination I participate in a J service platform project , to reveal empirical research literature information service platform associated recommend knowledge associated .
