The Research Of Periodical Literature Knowledge Warehouse Construction For Knowledge Service

With the rapid development of computer network technology and the internet, the information resources are exponentially explosive growing. Because of the proliferation of information resources, people found that it became harder and harder to retrieval the information that they concerned through traditional retrieval way. With the development of information science and information processing technology, knowledge service is becoming a new research direction of information science, the development of knowledge service need the support of knowledge warehouse, and the construction of knowledge warehouse need the support of NLP technology, text mining technology and so on. And with the development of these technologies, to build knowledge warehouse becomes possible.Therefor, this paper starts from the view of knowledge service and will build a warehouse of periodical literature, which can provide users periodical literature knowledge services. First, this paper gives the research status at home and abroad of knowledge warehouse, and it choses the periodical literature as research subject, and then it analysis the main technology which have been used to build knowledge warehouse. These technologies include Chinese natural language process, text mining technology, and data warehouse technology and so on. For Chinese natural language process this paper mainly uses HNC theory, and this theory is advanced in Chinese language processing, and it provides a new approach to Chinese natural language process. Under the guidance of these technologies theory, this article puts forward that use literature knowledge element to represent literature knowledge,and represent literature knowledge element with a six-tuple based on the analysis of the basis structure of journals. And then it designs the extraction method of knowledge element and its storage structure based on six-tuple, and build the journals knowledge database. And then it designs the method to extract knowledge element from knowledge database, and design the basis structure of the knowledge warehouse and its storage structure. At last, this article analysis the applications based on knowledge warehouse, include knowledge element query and display, visualization of knowledge element link, and knowledge mining services.The main purpose of this paper is to put forward the basis structure and building process of knowledge warehouse for periodical literature, and then it can provide journals knowledge services for users. The main feature of this paper is to put forward a new represent of literature knowledge element, and designs a practical knowledge warehouse structure, and it provides a new idea for the research for knowledge warehouse and knowledge services.
