HARD Experiment at Maryland: From Need Negotiation to Automated HARD Process

Our aim of participating in this year’s High Accuracy Retrieval from Documents (HARD) track is to explore the possibility of developing an automated HARD retrieval model by leveraging existing models and theories about information need negotiation in information science. The clarification questions we developed are related to four different aspects of search topic, and four different techniques were developed to fully use the information collected from the user through these questions. Our initial analysis of the results indicates that this is a promising approach.
