UT Austin in the TREC 2012 Crowdsourcing Track's Image Relevance Assessment Task
Abstract
We describe our submission to the Image Relevance Assessment Task (IRAT) at the 2012 Text REtrieval Conference (TREC) Crowdsourcing Track. Four aspects distinguish our approach: 1) an interface for cohesive, efficient topic-based relevance judging and reporting judgment confidence; 2) a variant of Welinder and Perona's method for online crowdsourcing [17] (inferring quality of the judgments and judges during data collection in order to dynamically optimize data collection); 3) a completely unsupervised approach using no labeled data for either training or tuning; and 4) automatic generation of individualized error reports for each crowd worker, supporting transparent assessment and education of workers. Our system was built start-to-finish in two weeks, and we collected approximately 44,000 labels for about $40 US.
