Exploring archival social media information resources under the background of big data is not only a strategic step in the construction of archival informatization,but also an inevitable choice for effective development and utilization. The information organization and information service of archival social media deserve to be studied deeply：the metadata construction of archival social media information organization should be studied; the metadata organization and metadata construction of integrating archival media information should be standardized by drawing lessons from the international standards of document management system and the reference model of Open Archival Information system; and the archives should be standardized. The integration system architecture of social media data integration is studied,which includes collection tools,analysis tools, retrieval engines and data information display platform. The information extraction,repeatability analysis and correlation analysis techniques in integration are optimized.
