    Abstract

    We introduce a new search strategy, in which the information retrieval (IR) query is inferred from eye movements measured when the user is reading text during an IR task. In training phase, we know the users’ interest, that is, the relevance of training documents. We learn a predictor that produces a “query” given the eye movements; the target of learning is an “optimal” query that is computed based on the known relevance of the training documents. Assuming the predictor is universal with respect to the users’ interests, it can also be applied to infer the implicit query when we have no prior knowledge of the users’ interests. The result of an empirical study is that it is possible to learn the implicit query from a small set of read documents, such that relevance predictions for a large set of unseen documents are ranked significantly better than by random guessing.
