基于OWL-DL的制造加工服务描述建模方法

Machining services description modeling based on OWL DL

为解决Internet上大量制造服务描述的异构性问题,实现网络环境下制造加工服务的快速发现与匹配,提出了二层—三元组模块化制造加工服务描述建模方法,构建了由核心本体和可扩展本体组成的制造加工服务描述语义网。为实现制造服务分类及其语义相似匹配推理,用描述逻辑建立制造加工知识之间的关系及其约束公理,运用Web本体语言OWL-DL实现制造加工服务规范描述。给出了面向用户的制造服务描述模型生成与应用框架,开发了支持"制造加工公共服务平台"构建的制造加工服务规范化描述建模和自动化发现与匹配的原型应用系统。

To solve a large number of heterogeneous manufacturing services description problems on the Internet,and realize quick searching and matching of Machining Services（MS） under the networked environment,an approach of 2-tire-3-tuple modularity MS description modelling was proposed,and the semantic network of MS description was established which was consisted of the core ontology and the extendable ontology.Aiming at realizing manufacturing service classification and its semantic similarity matching reasoning,the relationships and constraints axioms among manufacturing process knowledge built-in MS was represented with Description Logic（DL）,and the MS ontology model based on DL was described normally using OWL DL.A user-oriented MS description generation model and application framework were put forward.An application prototype with the standardized description modelling and automatic searching and matching of MS was developed to support the construction of public MS platforms.
