Massive data aggregation method and system based on cloud computing platform

The invention discloses a massive data aggregation method and system based on a cloud computing platform, and the method comprises the following steps: extracting key words of a network application from data of the network application; computing the semantic similarity between the key words of the network application and an ontology in an ontology base, and determining the similar ontology of thenetwork application in the ontology base; marking the data of the network application which is similar to the ontology in the ontology base through RDF (resource description framework) description; and storing the data of the network application in network resource storage nodes under the similar ontology of the ontology base. The invention provides the method for aggregating massive data of SAAS(software-as-a-service) applications, Internet applications and other network applications, semantic information is adopted for carrying out cluster analysis on the extracted data, and the data processing is more accurate and reliable.
