Fuzzy Computational Ontologies in Contexts (海外版)




计算本体(computational ontology)是对概念以及概念间的各种关系的一种形式化表述,是知识表示、语义网、智能主体等人工智能主要研究领域中的重要研究对象。《情境中的模 糊计算本体(英文版)》提出了一个基于模糊集的、可表达对象对于概念的归属程度(object membership)和对象在概念中的典型程度(object typicality)的形式化计算本体模型,以具体例子论证了此形式化模型的必要性和重要性;指出了情境(context)对物体归属程度和典型程度的 影响,并对此加以形式化;最后讨论了此形式化模型在推荐系统中的应用,用实验证明利用对象典型程度,或把对象典型程度加到协同过滤法后,能进一步提高模型 的准确性。
