Building blocks for semantic search engines: Ranking and compact indexing in entity-relation graphs
We see an evolutionary path to supporting semantic search over text facilitated by
- extractors and annotators for ever-growing collections of entity and relation types and
- 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.
