Research On Ontology-based Knowledge Management System Of Government Departments Model

Knowledge explosion time's oncoming, provided the rich knowledge resources for the humanity, the humanity already entered the era of knowledge economy. The release of information dissemination and use are no longer limited by time and space of, people in labor productivity and transform the natural, the work will be, use, accumulation, transformation and knowledge for more information. Internet search engine, enter keywords, you can quickly find a lot of information. But also make people get lost in the vast ocean of information, How to choose the most necessary knowledge? How to timely transfer of knowledge to those most in need? How to manage the vast amounts of knowledge resources? How to realize the knowledge increment and the innovation? Are we now face the most serious problems.Companies have built their own development of knowledge management systems, to the knowledge production, the assignment and the use carry on the management, obtains the competitive advantage by this. Agricultural knowledge management is to address the organization of agricultural knowledge, sharing, integration, exchange and service, agricultural knowledge engineering infrastructure an important aspect of agricultural knowledge to maximize the dissemination and use of an immeasurable role. But the system interoperability is not strong, can not be timely internal and external communication, knowledge that there is no uniform standard, knowledge transfer will occur during the semantic heterogeneity for these problems, the government learn from the knowledge management system can also be according to their actual situation and avoid the shortcomings of enterprise knowledge management system to build a knowledge management system. The Government department and the enterprise construction knowledge management system's final goal is different, one is the profit, one is the service. However, knowledge management, both important and difficult issues are knowledge sharing, realize knowledge innovation. As the Government has a strict organizational structure and level of restrictions on rights and obligations of distinction between higher and lower levels is evident, for the knowledge-sharing has brought many difficulties. We can fully use of advanced information technology and communication technology, according to existing knowledge management system is suited to the development of a new era of knowledge management systems. Create a good government culture, organizational forms and working environment within the Government to explore the natural and staff of tacit knowledge accumulated in mind, to guide knowledge innovation, knowledge share and knowledge reuse, and ultimately enhance the Government's overall competitiveness, improve decision-making accuracy and efficiency, reduce costs and expenditure, streamlining and staff, public and government affairs to public scrutiny, and better serve the people.Therefore needs to introduce the Onlology and expert's help, Onlology and realization of the original combination of knowledge management systems, traditional knowledge management system to solve the shortcomings and problems, to achieve knowledge sharing, reuse and innovation. Traditional government knowledge management system in the knowledge acquisition when an area can not contain all the knowledge content, and ontological theory can be constructed using the Protege ontology software to capture all the knowledge in the field, and a unified indexing, stored in the Knowledge Base at the same time can reveal the characteristics and interrelationships of knowledge; In the knowledge retrieval process, the realization of semantic retrieval, including both upper and lower words, synonyms and antonyms, but also the semantic reasoning, helping improve the precision rate and recall rate; In the knowledge innovation stage, tacit knowledge exists in the human brain, can not be shared, which need to build individual Onlology, individuals have skills, experience for conceptual description of the individual Onlology formed after the exchange of body tissue, through the integration of different organizations form the final government Onlology, through the exchange platform for knowledge transfer and reorganization, the ultimate realization of knowledge innovation.Government departments must recognize that tacit knowledge and explicit knowledge transformed question. Explicit knowledge, people can be lectures, textbooks, reference materials, magazines, patent documents, audio-visual media, software and database access, etc., it is convenient cross-language books, text, databases, coding modes, can be said visible. Tacit knowledge is stored in the human brain is in the experience, skills, experience, understanding, know-how not yet open secret knowledge is intangible invisible, does not belong to the scope of information.Generally speaking the stealth knowledge basic cannot very standard fast carry on the transmission, involves to many individual world outlooks, values and outlook on life and so on. But now the error is that people only pay attention to the role of explicit knowledge, see the tip of the iceberg, ignoring the tacit knowledge behind this great resource stocks.Final point to note is that, in the realization of knowledge sharing and knowledge innovation, while ensuring the safety of knowledge. Some knowledge of certain groups to have a certain permissions. Provides a flexible security management mechanism, in the same database, different documents, even in the same document with different sections can be different levels of confidentiality protection, allowing a good knowledge of the sector or government resources to rights management.The first chapter introduces the background papers, meaning, purpose, method; innovation and so on. The second chapter focuses on a number of papers related to knowledge, such as:ontology theory, knowledge management, knowledge innovation,etc.;The third chapter is the ontology in the role of government knowledge management, ontology-based knowledge management system of government characteristics, knowledge sharing and security issues; The fourth chapter is the government knowledge management model and the ontology union, is mainly composed of several modules, as well as each module function; Chapter V is positive, the software built using the Protege knowledge of Jilin City government website domain ontology. Chapter VI is a summary and outlook.Innovation of this paper is that the original government knowledge management model based on ontology theory to build with all the knowledge of the domain ontology, mainly concentrated in the knowledge of the collection, coding and innovation in three aspects, taking special consideration to achieve with Ontology knowledge sharing and reuse the same time, knowledge of security issues, but also put forward some concrete ways and measures to avoid leakage of confidential documents of government departments, to fully protect the safety of all knowledge.Ontology and the existing government knowledge management system model by combining the knowledge of the government's effective management, and help create a good cultural environment for the Government's management, service delivery, decision-making, etc. play an important role the government should increase funding and related investment in science and technology personnel, establish and improve intelligent knowledge management system.
