中文简介:
本体论是形式化和共享知识的基本工具。然而,通常特定领域的概念化取决于特定用户的需求。我们提出了一种方法来执行以用户为中心的本体填充,该方法在每个步骤中都有效地将人包含在循环中。考虑到合适的目标本体的存在,我们的方法支持使用新的分层分类方法将用户概念化中的概念与目标本体的概念对齐。我们的方法还帮助用户构建、改变和发展其初始概念化,利用目标本体和从非结构化数据中提取的新事实。我们在医疗领域的一个真实案例中评估了我们的方法,其中从用户博客中提取的药物反应的不良短语与MedDRA概念相一致。评估表明,我们的方法在帮助用户构建初始本体方面具有很高的效率并保持。
课程简介: Ontologies are a basic tool to formalize and share knowledge. However, very often the conceptualization of a specific domain depends on the particular user’s needs. We propose a methodology to perform user-centric ontology population that efficiently includes human-in-the-loop at each step. Given the existence of suitable target ontologies, our methodology supports the alignment of concepts in the user’s conceptualization with concepts of the target ontologies, using a novel hierarchical classification approach. Our methodology also helps the user to build, alter and grow their initial conceptualization, exploiting both the target ontologies and new facts extracted from unstructured data. We evaluate our approach on a real-world example in the healthcare domain, in which adverse phrases for drug reactions, as extracted from user blogs, are aligned with MedDRA concepts. The evaluation shows that our approach has high efficacy in assisting the user to both build the initial ontology  and to maintain it.
