Evaluation of Term Ranking Algorithms for Pseudo-Relevance Feedback in MEDLINE Retrieval
OBJECTIVES The purpose of this study was to investigate the effects of query expansion algorithms for MEDLINE retrieval within a pseudo-relevance feedback framework. METHODS A number of query expansion algorithms were tested using various term ranking formulas, focusing on query expansion based on pseudo-relevance feedback. The OHSUMED test collection, which is a subset of the MEDLINE databas...
متن کاملImproving retrieval performance by relevance feedback
Relevance feedback is an automatic process, introduced over 20 years ago, designed to produce improved query formulations following an initial retrieval operation. The principal relevance feedback methods described over the years are examined briefly, and evaluation data are included to demonstrate the effectiveness of the various methods. Prescriptions are given for conducting text retrieval o...
متن کاملImproving image retrieval performance with negative relevance feedback
Learning user perception of an image is a challenging issue in interactive content-based image retrieval (CBIR) systems. These systems employ relevance feedback mechanism to learn user perception in terms of a set of model-parameters and in turn iteratively improve the retrieval performance. Since the quantity of user feedback is expected to be small, learning the user’s perception essentially ...
متن کاملImproving Content-Based Image Retrieval with Relevance Feedback
In this paper, we present an effective approach for improving content-based image retrieval (CBIR) with relevance feedback. A rectangular image segmentation technique is used for feature extraction in image retrieval. Then an image object matching algorithm is proposed for image retrieval. Finally, a feature reweighting approach is used for relevance feedback, which transforms object features i...
متن کاملRanking and Feedback-based Stopping for Recall-Centric Document Retrieval
Systematic reviews require researchers to identify the entire body of relevant literature. Algorithms that filter the list for manual scanning with nearly perfect recall can significantly decrease the workload. This paper presents a novel stopping criterion that estimates the score-distribution of relevant articles from relevance feedback of random articles (S-D Minimal Sampling). Using 20 trai...
