Social Networking & Discovery (SaND) is an aggregation platform for information discovery and analysis. It leverages the complex relationships between content and people that surface through social applications. Its integrated index supports the combination of content-based analysis and people-based analysis over a rich data foundation.

The cornerstone of the SaND platform is its ability to aggregate information from different sources for any entity while preserving its relations with other entities. For example, a blog post representation will include all the text in the post (including comments), and will have connections to the blog author and every commenter, as well as to tags used on the post either internally or through a tagging system.
