We see an evolutionary path to supporting semantic search over text facilitated by 1. extractors and annotators for ever-growing collections of entity and relation types and 2. search systems that exploit a smooth continuum between structured entities and relations on one hand and uninterpreted text on the other. The extractors and annotators will be imperfect and incomplete.
