Query Adaptation Techniques

• “In the course of a search session, a user creates and moves along a path of images. In every iteration, the path changes and the query needs to be adapted accordingly. The objects are treated as evidence of the user’s information need, with a changing degree of uncertainty associated to each object: the older the evidence, the more uncertain it is that it is still indicative of the current information need. The degree of uncertainly is represented by the ostensive relevance profile.

• The query is comprised of the weighted sum of evidence found in the path objects … collected from the documents’ features.”
