Web-based global news content, especially when delivered via social media, is highly dynamic and hence subject to the detriments of link rot and content drift immediately after publication. To address these issues, we are building SoLoGlo, a capture and archival service for social media collections that supports the longevity of multi-perspective histories of world events. SoLoGlo incorporates functions to collect and preserve content, proactively archiving embedded web resources, performing rapid analysis and data mining tasks, and linking related content between otherwise disjoint collections.
