针对大数据体量巨大、种类多样、速度极快、价值稀疏的特点，提出了基于本体的网络大数据信息处理架构。 该架构通过历史大数据对本体模型不断丰富，在形成面向大数据主题知识库的基础上，对网络大数据进行语义分析，实现价值 服务。

Aiming at the big amount of big data with species diversity, high speed and value sparse, this paper proposes information architecture for network big data based on ontology. It enriches the ontology model through the history big data to form subjectoriented knowledge base for big data. This information architecture realizes the value of service through semantic analysis.
