Research On The Building Of Domain Knowledge Element Based On Ontology

We have vast amounts of information but the effectively obtain of the required knowledge being increasingly difficult. The existing mode of knowledge management is also seeking the road of change. About the indexing and retrieval of knowledge study, the artificial intelligence searching, and the research and exploration of the semantic web technology, etc., are all now in order to solve the traditional way of knowledge management cannot meet the users’problem of knowledge acquisition and utilization. And how to use the large amount of data to get the knowledge to solve practical problems in life, or to help people in handling daily events for scientific decision-making, has become scholars’research problems in the era of big data in various fields. In this context, how to effectively manage and use the knowledge, and for further research of knowledge reasoning and knowledge innovation, has become the scholars research problems in the field of knowledge management.As early as the late20th century, scholars in the field of information science have already realized the management of knowledge unit need to be further refined to knowledge. Knowledge element can be simply understood as the smallest unit of knowledge that is able to express a complete semantic. There are more and more researchers to study the knowledge element and combining with the knowledge of the field of structural characteristics, the application of knowledge in this field has made the exploration. However, the knowledge element theory is not very mature, the research of knowledge element is still at a preliminary stage. How to define the structure of knowledge element, how to quickly build and effectively organize and use knowledge element is still not very clear.There is being a lot of progress in this aero.Based on the domain knowledge element’s build problems, this thesis introduces the technology of ontology. Combined the ontology of knowledge organization and the research of ontology, this thesis tries to declare ontology and domain knowledge element’ problems such as the design of the process. Based on domain knowledge element building problems, introduces the semantic category in related theory and technology of ontology.The ontology of knowledge organization could be used on knowledge element, combine the theory and research, probes into the knowledge structure model based on ontology, and knowledge element in the field of design. In domain ontology construction method is studied on the basis of the combination of knowledge element processing method, use XML to extract the knowledge element in a structured manner, and as a concrete example is added to the domain ontology. Based on ontology knowledge model framework, under the guidance of the theory of method for the construction of domain knowledge ontology, with classic in the field of history of the Records of the Three Kingdoms as an example, the main core characters, including the important events of knowledge element extraction and presentation, and according to the characteristics of historical knowledge element one design of the core concepts in the Records of the Three Kingdoms and its hierarchy relation and property relation between concepts, and finally to extract the knowledge element as instance added to the domain ontology, finished the history domain knowledge ontology construction.
