Research On Knowledge Warehouse For Sportswear Knowledge Management

At the knowledge economy era, knowledge could have been used as production factor for being put into production, like capital, labor and raw materials.For the garment industry, especially the sportswear garment industry, higher requirements on enterprise technology innovation have been put forward due to a lot of characteristics of sportswear. Sports clothing enterprises have accumulated much design experience, technology and product instance and so on, but lacked the effective knowledge management approach. The accumulated knowledge cannot so be got effective reuse and innovation that secondary development and technical innovation ability are weak. Now, knowledge reuse has been accepted and emphasized by effective management on knowledge. In the apparel industry, construction and application of knowledge management system have gained wide public attention on account of science and technology of sportswear. Many enterprises have already organized development and application of knowledge management system so that knowledge can be reasonably managed and used as scientific and technological productive forces. There are many knowledge representation methods, on which many scholars have carried out extensive research. Representing knowledge with ontology have been widely accepted by people. Knowledge storage has been key issues and difficult problems of constructing knowledge management system because of a lot of characteristics of knowledge. Knowledge warehouse is the hardware foundation of knowledge management and also the basis of the knowledge management system, building a reasonable knowledge warehouse is the key problem for guaranteeing normal operation and sustainable maintenance.The main research content of this article as the following several aspects:(1)The topic research background were introduced, present situation and existing problems were pointed out,the research purpose and meaning were clear;Doing research on the technical theory of the topic. Including data base, knowledge base, data warehouse, knowledge warehouse, ontology theory, the OSI layered design ideas and technology, all of which provide theoretical and technical support to this paper.(2)Analyze the characteristics of sportswear knowledge, sportswear knowledge warehouse solutions are put forward,then sportswear knowledge were expressed by ontology, then storage content of sportswear knowledge warehouse were clear.(3)According to layered idea of application technology and services and design ideas of high cohesion and low coupling, through the analysis research of the composition of knowledge warehouse and characteristics of sportswear ontology knowledge, the general method to construct sportswear technology knowledge warehouse were provided, and a sportswear technology knowledge warehouse model were built;(4)Studied the knowledge structure based on ontology how to storage in knowledge warehouse, the structure of the ontology knowledge and relational database were compared, the database list form and structure of the tree representation of ontology knowledge were comparison and analysis,the method of how to use a relational database storing the structure of the ontology knowledge data were studied,the knowledge storage solution were validation by using recursive algorithm.(5)Studied the knowledge structure of dynamic operational problems,due to the dynamic changes of the ontology knowledge structure characteristics, Mainly analyed from the knowledge of dynamics, the chain table structure, tree structure which are the effects of operation,the dynamic operation method were concluded.And the operating method were encapsulated.(6)Sportswear knowledge warehouse prototype system was designed and implemented, and the method of knowledge storage and operation method were validated by this subject.In this study, the knowledge warehouse model is given at the base on the sportswear ontology;storage method of sportswear knowledge which is expressed by ontology stored in relational database were given; the dynamic operation method were studied; knowledge warehouse prototype system were built and sportswear construction method and operation are verified. This topic research, provide the basis to solve storage, retrieval, sharing and reuse of sportswear knowledge and a series of issues, make it possible that knowledge management system was applied in the sportswear industry.
