This paper presents a method of extracting domain ontology from WordNet. The novelty of the method is taking WordNet as one and only knowledge base, this can improve the efficiency of domain ontology building. In our method, kernel concepts are given by domain experts firstly, then IC-based semantic similarity algorithm is used to extract domain concepts from WordNet, in the end, domain concepts are...
Information Content (IC) is an important dimension of assessing the semantic similarity between two terms or word senses in word knowledge. The conventional method of obtaining IC of word senses is to combine knowledge of their hierarchical structure from an ontology like WordNet with actual usage in text as derived from a large corpus. In this paper, a new model of IC is presented, which relies on...
This paper presents a new model of measuring semantic similarity in the taxonomy of WordNet. The model takes the path length between two concepts and IC value of each concept as its metric, furthermore, the weight of two metrics can be adapted artificially. In order to evaluate our model, traditional and widely used datasets are used. Firstly, coefficients of correlation between human ratings of similarity...
The openness of Internet leads to security problems of network, among which content security is an important problem. In order to solve the problem effectively, a security scheme of information content which based on content security ontology (CSO) is presented. CSO is extracted from a security kernel (SK) which is a lexicon of information security knowledge drawing out from general thesaurus and...
