基于语义Web的股票信息表示模型

Stock Information Representation Modeling Based on Semantic Web

在分析查找互联网股票信息存在问题的基础上,给出了一个基于语义Web的股票信息表示模型.首先利用语义Web定义股票本体,给出了相应的RDF模式描述,对本体进行评估.其次,通过分析用户股票信息需求,利用构建的股票本体,给出基于语义Web的模型的体系结构,建立了一个能根据用户请求提供所需要的股票信息的股票信息表示模型;最后通过实例验证了该模型的有效性.

After analyzing the existing problems in searching stock information from the internet, this paper gave a stock information representation model with the technology of semantic web. Firstly, stock ontology was defined, corresponding RDF schema were shown and the ontology was evaluated. Secondly, the architecture of a stock information model based on semantic web was obtained by utilizing the stock ontology and analyzing user＇s stock information requirement, and the stock information representation model was established. This model can satisfy different demands of users. Finally, the validity of the model was verified by citing actual examples.
