摘要： 借鉴多目标决策树中规范化的思想，提出将一般指标体系结构规范化为由一个根节点和若干叶子节点构成的2层多叉树。根据领域本体的建模方法论，建立基于描述逻辑的指标体系本体模型，并利用本体编辑工具Protégé3.1.1将本体形式化，给出了基于RDF+OWL的形式化表示。利用Jena开发包和Agent开发平台Able开发了预警原型系统，从实验上论证了指标体系本体建模的正确性和其在预警系统中的应用可行性。

Abstract: Referring to the standardization about multi-objective decision-tree, the generic index-system model is standardized to a two-level tree which has a root and several leaves. According to the methodology about domain ontology modeling, the index-system ontology is modeled based on DL, and the ontology is formalized by Protégé3.1.1. The warning prototype system is established by Jena and Able, and it proves the feasibility about ontology introduced into warning system from the experiment.

Key words: ontology, index-system, warning system
