传统的专家识别系统大多采用一组带权重的关键词来表征专家的专长,然而这种基于关键词的专长描述不足以概括专家的研究主题。提出基于领域本体概念的专长表示方法,通过构建相应的领域本体来描述领域核心概念和概念间关系,利用谷歌距离来计算关键词到本体概念的语义相似度,完成关键词到概念的映射,从而得到基于本体概念的专长表示。
Traditional expert identification systems mostly use a set of weighted key words to characterize the expertise of an expert. However, this keyword-based description of an expert’s specialty is not sufficient to summarize an expert’s research topic. This paper proposes a method of representation based on the concept of domain ontology, constructs the corresponding domain ontology to describe the relationship between core concepts and concepts in the domain, calculates the semantic similarity between keywords and ontology concepts by using Google distance, and completes the mapping of keywords to concepts Obtain expertise based on the concept of ontology.
