摘要:

目前本体在数据融合应用中的兴趣越来越大。事实上,本体被看作是描述和推理传感器数据,对象,关系和一般领域理论的语义工具。此外,不确定性可能是数据融合处理的数据和信息的最重要特征之一。然而,本体论的基本性质意味着本体论只描述世界上断言的和真实的事实。不同的概率,模糊和证据的方法已经存在,以填补这一空白,本文回顾了最流行的工具。然而,没有一个工具完全符合我们的目的。因此,我们构建了一个Dempster-Shafer本体,可以导入到任何特定的领域本体,使我们能够以不确定的方式实例化它。我们还开发了一个Java应用程序,使推理这些不确定的本体实例。

英文摘要:

Nowadays ontologies present a growing interest in Data Fusion applications. As a matter of fact, the ontologies are seen as a semantic tool for describing and reasoning about sensor data, objects, relations and general domain theories. In addition, uncertainty is perhaps one of the most important characteristics of the data and information handled by Data Fusion. However, the fundamental nature of ontologies implies that ontologies describe only asserted and veracious facts of the world. Different probabilistic, fuzzy and evidential approaches already exist to fill this gap; this paper recaps the most popular tools. However none of the tools meets exactly our purposes. Therefore, we constructed a Dempster-Shafer ontology that can be imported into any specific domain ontology and that enables us to instantiate it in an uncertain manner. We also developed a Java application that enables reasoning about these uncertain ontological instances.
