Rutgers' TREC-7 Interactive Track Experience

Rutgers Interactive Track at TREC-5

The Interactive Track investigation at Rutgers concentrated primarily on three factors: the searchers’ uses and understandings of relevance feedback and ranked output, and the utility of relevance feedback for the interactive track task; the searchers’ understandings of the interactive track task; and performance differences based on topic characteristics and searcher and order effects. Our off...

The goal of the Rutgers TREC-6 Interactive Track study was to compare the performance and usability of a system offering positive relevance feedback with one offering positive and negative relevance feedback. Our hypothesis was that the latter system would better support the aspect identification task than the former. Although aspectual recall was higher for the system supporting both kinds of ...

Support for Question-Answering in Interactive Information Retrieval: Rutgers' TREC-9 Interactive Track Experience

We compared two different interfaces to the InQuery IR system with respect to their support for the TREC-9 Interactive Track Question-Answering task. One interface presented search results as a ranked list of document titles (displayed ten at one time), with the text of one document (the first, or any selected one) displayed in a scrollable window. The other presented search results as a ranked...

Thirty-four subjects each searched on four of the Interactive Track topics, in one of two conditions: a “box” query input mode; and a “line” query input mode. One-half of the subject...
