Abstract
Disclosed is a system, method, and computer program product for relating a metadata tag to a television program identifier and associating a hashtag with metadata associated with the television program. A mapping server receives a request that includes a metadata tag (e.g., a hashtag) for a social object, such as a comment or a post to a social network. The mapping server generates a graph to determine a set of television program identifiers likely associated with the metadata tag. Furthermore, the mapping server compresses graph data over time to reduce the time needed to perform a query to the graph.
