摘要:
 股票市场中一些事件容易影响股票的价格及收益。为辅助投资者积累经验性知识及快速做出决策，文中在收集主题事件的基本信息及市场波动数据的基础上，结合本体理论和案例推理方法，通过对事件案例的本体结构定义以及对金融事件类型本体的构建，开发了股票市场主题事件案例的推理系统原型。该系统用 OWL-DL 语言描述本体，采用Protégé4.2构建本体库；通过分析主题事件的特征属性，用相似性度量方法检索相似案例，进而对目标事件做出详细分析。通过特定事件对股票市场的走势分析，验证了用相似案例进行市场短期预测具有可行性，同时引入本体后在推理系统的查全率上有了明显的提高，从而说明该方法是合理的、有效的。
Abstract:
 In stock markets there are some events that their occurrences will significantly affect stocks’ prices and profits. In order to help investors accumulate experimental wealth and quickly make decisions,in this paper a case-based reasoning system for subject events in stock markets was constructed with the combination of ontology theory and case-based reasoning method,then with information about subject events and data about market fluctuations,the ontology structures were defined for event cases and type ontologies were set for fi-nancial events. In this system,OWL-DL was used to describe ontology,and Protégé4. 2 was applied to build the ontology base. By stud-ying the feature properties and using similar measuring method to retrieve similar cases,a target event was finally analyzed in detail. In the end a trending analysis for a certain event to the stock markets was given,the results showed that using similar cases to predict short-term market effect was feasible,and meantime the recall ratio was obviously improved after introducing ontology into the reasoning system, which means that the proposed method is reasonable and effective.
