QA4PRF: A Question Answering Based Framework for Pseudo Relevance Feedback
Pseudo relevance feedback (PRF) automatically performs query expansion based on top-retrieved documents to better represent the user’s information need so as to improve the search results.

Relevance feedback models for recommendation [PDF]
We extended language modeling approaches in information retrieval (IR) to combine collaborative filtering (CF) and content-based filtering (CBF). Our approach is based on the analogy between IR and CF, especially between CF and relevance feedback (RF). Both CF and RF exploit users' preference/relevance judgments to recommend items. We first introduce a

Exploring accumulative query expansion for relevance feedback [PDF]
For the participation of Dublin City University (DCU) in the Relevance Feedback (RF) track of INEX 2010, we investigated the relation between the length of relevant text passages and the number of RF terms.

Implementing Relevance Feedback for Content-Based Medical Image Retrieval
Content-based image medical retrieval (CBMIR) is a technique for retrieving medical images on the basis of automatically derived image features such as colour, texture and shape. There are many applications of CBMIR, such as teaching, research, diagnosis

An Adaptive Weight Method for Image Retrieval Based Multi-Feature Fusion
With the rapid development of information storage technology and the spread of the Internet, large capacity image databases that contain different contents in the images are generated.

Modified one-class support vector machine for content-based image retrieval with relevance feedback
Image retrieval via traditional Content-Based Image Retrieval (CBIR) often incurs the semantic gap problem—non-correlation of image retrieval results with human semantic interpretation of images.

A simulated study of implicit feedback models [PDF]
In this paper we report on a study of implicit feedback models for unobtrusively tracking the information needs of searchers. Such models use relevance information gathered from searcher interaction and can be a potential substitute for explicit ...

Neurophysiological evidence for evaluative feedback processing depending on goal relevance
Feedback signaling the success or failure of actions is readily exploited to implement goal-directed behavior. Two event-related brain potentials (ERPs) have been identified as reliable markers of evaluative feedback processing: the Feedback-Related ...
