Data characterizing a result set corresponding to a query of a social media dataset can be received. The query can include a first context including a first context identifier. The result set can include a first entity and a second entity. The first entity can include a first entity identifier and the second entity can include a second entity identifier. A key set can include a first fixed length key characterizing the first entity identifier in the first context. The key set can further include a second fixed length key characterizing the second entity identifier in the first context. The key set including the first fixed length key and the second fixed length key can be deduplicated. A first relevance score associated with the first context can be determined using the deduplicated key set. The first relevance score can be provided.
