Ontology Acquisition Method And Learning In The Study Of Cognitive Strategies

How to effectively acquire and design learning resources is an important research content in the field of educational technology, especially use computer technology to obtain learning resources with certain automatic. In a number of learning resources, disciplinary domain knowledge has been the main contents of the primary and junior school teaching, and in the field of computer, there are also studies devoted to knowledge in the field of computer processing, which uses a computer knowledge representation to form to express domain knowledge contained in the content. Ontology as a more mature knowledge representation can be used to clearly express specific areas inside knowledge of the concepts and knowledge between the relationship, through the association between knowledge and the formation of the corresponding knowledge system. Although the form is relatively simple, but high quality can be used for computer processing or human learning ontology is very few, especially traditional by hand to obtain the ontology is time-consuming and laborious, in the face of the network and chaotic learning resources, only by human to search is very difficult, in search of also need to exclude a large number of irrelevant content, sometimes will miss important content. And different researchers to a certain content of understanding will be different, so that the manual construction of ontology standards are not uniform, which can not generate a high quality of the subject area ontology. More than that, a lot of the time there will not make full use of the resources, which is not to promote learning with the learning resource. Because the ontology is generally for computer processing, and the core of computer data processing is the algorithm, algorithm has the steps clear, consistent with the cognitive habits of human beings. So will algorithm into the cognitive process of ontology can be ontology as a kind of learning resource into educational technology research field, so that it can be used to study design or instructional design, in order to help learners to learn. Therefore, it is particularly important to study the ontology acquisition method, especially to a certain extent, the automatic acquisition method and the use of ontology to facilitate the study of the learner.This study is based on the junior middle school physics domain ontology construction project, give full consideration to the hand built ontology method of defects, using related computer technology (web crawler, natural language processing) of ontology automatic acquisition method of inquiry, the design and implementation of the automatic acquisition method (algorithm) corresponding to the body, in a certain extent achieve the automatic acquisition of terminological ontologies. And a thorough study on how to preserve the ontology terms is carried out. The feasibility and effectiveness of the method are pointed out and the feasibility and effectiveness of the method are pointed out. Finally, based on the knowledge of the ontology, the ontology based cognitive strategy based on structured knowledge is proposed, which makes full use of ontology learning resources.The first chapter clarifies the significance and main contents of the study, and introduces the research status at home and abroad.In the second chapter, it introduced ontology concepts and features, explains what is the ontology and the semantic features, discusses the ontology acquisition technology route and main methods, and focuses on the artificial acquisition and automatic acquisition of two kinds of main methods.The third chapter is the second chapter based on the method of acquiring ontology description, implementation of the method in the second chapter of the paper introduced. And the storage method of ontology is studied.The fourth chapter introduces the domain ontology construction method and compares the manual and automatic two kinds of ontology acquisition methods.The fifth chapter puts forward the ontology cognition strategy from the perspective of instructional design, the design of the learning process of the corresponding.The sixth chapter is the summary and outlook.
