OSIA: Open Source Intelligence Analysis System Based on Cloud Computing and Domestic Platform

Information safety is significant for state security, especially for intelligence service. OSIA (open source intelligence analyzing) system based on cloud computing and domestic platform is designed and implemented in this paper. For the sake of the security and utility of OSIA, all of the middleware and involved OS are compatible with domestic software. OSIA system concentrates on analyzing open source text intelligence and adopts self-designed distributed crawler system so that a closed circle is formed from intelligence acquisition to analysis process and push service. This paper also illustrates some typical applications of anti-terrorist, such as the "organizational member discovery" based on Stanford parser and cluster algorithm, the "member relation exhibition" based on paralleled PageRank algorithm and the like. The results of experiences show that the OSIA system is suitable for large scale textual intelligence analysis.
