讲座摘要：There exist a handful of natural language processing and machine learning approaches for extracting Description Logic concept definitions from natural language texts. Typically, for a single target concept several sentences in natural language are used, from which candidate concept descriptions are obtained. These candidate descriptions may have confidence values associated with them. In a final step, the candidates need to be combined into a single concept, in the easiest case by selecting a relevant subset and taking its conjunction. However, such generated concept descriptions can still contain fake information which is harmful to be added into a formal knowledge base. In this talk, I will present an approach to selecting relevant candidates by a nonstandard automated reasoning for description logic EL， and apply it for assisting the development of the widely used biomedical ontology SNOMED CT.
