基于Web本体描述语言的偏好表示和推理

OWL-based preference representation and reasoning

在偏好的逻辑链表示方法的基础上,提出了使用Web本体描述语言来表达偏好的方法。通过使用Web本体描述语言可以将偏好的表达和推理很自然地结合在一起,而成熟的描述逻辑推理器可保证用Web本体描述语言来表达偏好的实用性。应用偏好算子使用户能够表达复杂的偏好,满足了用户多样化的搜索需求。此外,使用Web本体描述语言还可以增加条件偏好,从而增强偏好的表达能力。

Based on the preference reasoning by manipulating logical chain, a preference representation method using Web Ontology Language （OWL） was proposed. By OWL, the preference representation and reasoning could be combined, and the mature Description Logics （DL） reasoners, such as Racer, Jena, Fact＋＋and Pellet, could ensure the practicality of this technology. Preference operators could help users to express complicated preference when the user needed to conduct a complicated search. Furthermore, conditional preference could be easily added so that the expressiveness was enhanced.
