Position-based contextualization for passage retrieval
Proceedings of the 22nd acm international conference on information …, 2013•dl.acm.org
We present a novel contextualization approach for passage retrieval. The core principle is to
let any occurrence of a query term in a document affect the passage retrieval score, whether
the occurrence is in the passage or not. This effect is controlled by the distance between the
term occurrence and the passage. Empirical evaluation demonstrates the merits of our
approach; the resultant retrieval performance substantially transcends that of previously
proposed passage retrieval methods, including those that use various contextualization …
