Suggesting search tactics
The work honored with the paper award at the ECIR 2010 conference described an experiment that assessed the effectiveness of a case-based reasoning mechanism for suggesting possible actions for users engaged in an exploratory search task. The authors constructed DAFFODIL, a sophisticated interface for issuing queries, for saving documents, and for suggesting potentially useful query expansion terms. They performed a preliminary evaluation of the system on three search tasks, and compared subjects’ performance and behavior patterns with and without system-generated suggestions.
