A multiple relevance feedback strategy with positive and negative models. [PDF]

open access: yesPLoS ONE, 2014
A commonly used strategy to improve search accuracy is through feedback techniques. Most existing work on feedback relies on positive information, and has been extensively studied in information retrieval. However, when a query topic is difficult and the

A multi-dimensional semantic pseudo-relevance feedback framework for information retrieval [PDF]

open access: yesScientific Reports
Pre-trained models have garnered significant attention in the field of information retrieval, particularly for improving document ranking. Typically, an initial retrieval step using sparse methods such as BM25 is employed to obtain a set of pseudo ...

A Query Expansion Method Using Multinomial Naive Bayes

open access: yesApplied Sciences, 2021
Information retrieval (IR) aims to obtain relevant information according to a certain user need and involves a great diversity of data such as texts, images, or videos. Query expansion techniques, as part of information retrieval (IR), are used to obtain

Positional relevance model for pseudo-relevance feedback [PDF]

open access: yesProceedings of the 33rd international ACM SIGIR conference on Research and development in information retrieval, 2010
Pseudo-relevance feedback is an effective technique for improving retrieval results. Traditional feedback algorithms use a whole feedback document as a unit to extract words for query expansion, which is not optimal as a document may cover several different topics and thus contain much irrelevant information.

Implicit Adaptation Is Modulated by the Relevance of Feedback [PDF]

open access: yesJournal of Cognitive Neuroscience, 2022
Abstract Given that informative and relevant feedback in the real world is often intertwined with distracting and irrelevant feedback, we asked how the relevancy of visual feedback impacts implicit sensorimotor adaptation. To tackle this question, we presented multiple cursors as visual feedback in a center-out reaching task and ...

Relevance Feedback in CBIR [PDF]

open access: yes, 2002
A new focus in content-based image retrieval (CBIR) research is applying relevance feedback originally developed for text document retrieval, to improve the retrieval performance. This effort tries to bridge the gap between low-level image features and high-level semantic contents of images as this gap is the bottleneck of CBIR.
