High-performance processing of text queries with tunable pruned term and term pair indexes

Autor:

Andreas Broschart

Ralf Schenkel

Resumen:

Term proximity scoring is an established means in information retrieval for improving result quality of full-text queries. Integrating such proximity scores into efficient query processing, however, has not been equally well studied. Existing methods ...

Olivier Chapelle

Thorsten Joachims

Filip Radlinski

Resumen:

Interleaving is an increasingly popular technique for evaluating information retrieval systems based on implicit user feedback. While a number of isolated studies have analyzed how this technique agrees with conventional offline evaluation approaches ...
