摘要
本体广泛应用于语义网、自然语言处理、数字图书馆等领域,而自动构建本体是这些领域的难点之一.全自动的本体构建以及如何令机器自己不断学习并更新已有的本体知识的研究仍然缺乏.提出了一种基于认知算法的中文本体自动构建方法,建立了自动构建本体的概念和物理模型,并根据此模型实现了一个初步的自动构建本体的工具,在此基础上基于某些公理化算子来实现对已有本体的扩充、缩减、修正等操作,实验证明该模型和系统很大程度上降低了在构建本体过程中的人力投入.
Ontology is widely used in the fields of semantic network, natural language processing, digital library and so on, while the automatic construction of ontology is one of the difficult points in these fields. There is a lack of research on fully automatic ontology construction and the approaches to maintaining the machine learning or updating the existing knowledge ontology. Research and implementation of automatic Chinese ontology-building tools based on cognitive algorithms creates a model of automatic Chinese ontology-building tool; meanwhile, a system is programmed to simulate this kind of ontology-learning. This system can do basic ontology-operations like ontology-expansion, ontology-reduction, ontology-correction and so on. And the results of all the above-mentioned experiments show that this model and system can reduce manpower on ontology engineering effectively.
