基于知网的可拓领域信息元库的构建方法

Construction of HowN et-based extendable domain information element base

为了解决某个领域的矛盾问题,须构建领域信息元库以提高计算机语义理解能力。结合知网的表达知识的形式化特点,提出了对基元进行改造,增强语义互操作性的方法。在知网2000版中,以教育领域为案例,提取出教育领域的概念及其属性,并在此基础上改造与更新,构造可拓学的教育领域基础库。在实验过程中采用关系型数据库实现了信息元的存储,表明了可以提高语义互操作能力,验证了该方法的可行性。

To solve contradictory problems in a domain, it is necessary to construct the domain information element base and to improve the semantic recognition ability of computer software. Combined with the characteristics of for- malized expression of knowledge in HowNet, this paper proposes an approach to redefine the construction of basic- element which is the logic cell of Extenics to enhance semantic interoperability. Taking the domain of education as an example, the concepts and their properties of education are extracted in HowNet 2000, and further reconstructed and updated. Thereby the basic-element base of Extenics in the domain of education is built. A relational database （SQL Express） has been used to store the information element in the experiment, showing that the new basic-ele- ment can improve semantic interoperability, and proving the feasibility of the method.
