Entity Relationship Search

November 23, 2010

A reader in Israel alerted me to an Entity Relationship search demo. Here’s what the Web site said:

Entity-Relationship Query (ERQ) is an entity-centric, structured query mechanism. You can query named entities by telling what kinds of entities you want and what are the relations among them.

The University of Texas – Arlington combines in one interface different types of access methods; specifically:

ERQ supports SQL-like structured queries, consisting of multiple predicates. On the other, the predicates are defined by keywords as in IR queries. We acknowledge that, the effectiveness of our approach partially relies on the user’s capability in providing proper keyword constraints, just like in IR queries. Some related works (e.g., EntityRank) is similar to ERQ in the sense that their queries are composed with keywords (as single-predicate queries in ERQ, not as narrative descriptions in INEX or TREC). However, those systems do not support multi-predicate queries. Besides, they only focus on precisions at top-few ranks, while in ERQ we attempt to maintain good precisions in longer range.

The demo runs on a chunk of Wikipedia. Worth a look.
