Score distributions for Pseudo Relevance Feedback [PDF]

open access: yesInformation Sciences, 2014
Abstract Relevance-Based Language Models, commonly known as Relevance Models, are successful approaches to explicitly introduce the concept of relevance in the statistical language modelling framework of Information Retrieval. These models achieve state-of-the-art retrieval performance in the Pseudo Relevance Feedback task.

Word Embeddings-Based Pseudo Relevance Feedback Using Deep Averaging Networks for Arabic Document Retrieval

open access: yesJournal of Information Science Theory and Practice, 2021
Pseudo relevance feedback (PRF) is a powerful query expansion (QE) technique that prepares queries using the top k pseudo-relevant documents and choosing expansion elements.

Query expansion using the clustering of pseudo relevant documents with query sensitive similarity [PDF]

open access: yesمجله مدل سازی در مهندسی, 2017
Query expansion as one of query adaptation approaches, improves retrieval effectiveness of information retrieval. Pseudo-relevance feedback (PRF) is a query expansion approach that supposes top-ranked documents are relevant to the query concept, and ...

Contrastive Refinement for Dense Retrieval Inference in the Open-Domain Question Answering Task

open access: yesFuture Internet, 2023
In recent years, dense retrieval has emerged as the primary method for open-domain question-answering (OpenQA). However, previous research often focused on the query side, neglecting the importance of the passage side.

An Improved Retrievability-Based Cluster-Resampling Approach for Pseudo Relevance Feedback

open access: yesComputers, 2016
Cluster-based pseudo-relevance feedback (PRF) is an effective approach for searching relevant documents for relevance feedback. Standard approach constructs clusters for PRF only on the basis of high similarity between retrieved documents.

Online Distillation for Pseudo-Relevance Feedback

open access: yes, 2023
Model distillation has emerged as a prominent technique to improve neural search models. To date, distillation taken an offline approach, wherein a new neural model is trained to predict relevance scores between arbitrary queries and documents. In this paper, we explore a departure from this offline distillation strategy by investigating whether a ...

Patent query reduction using pseudo relevance feedback [PDF]

open access: yesProceedings of the 20th ACM international conference on Information and knowledge management, 2011
Queries in patent prior art search are full patent applications and much longer than standard ad hoc search and web search topics. Standard information retrieval (IR) techniques are not entirely effective for patent prior art search because of ambiguous terms in these massive queries. Reducing patent queries by extracting key terms has been shown to be

A Study of Word Bigrams for Pseudo-relevance Feedback in Information Retrieval [PDF]

open access: yesJournal of Universal Computer Science
Traditional information retrieval models mostly adopt a term independence assumption and are based on single terms or unigrams. Past efforts have attempted to go beyond this assumption, such as by using contiguous terms (i.e.

Improving Pseudo-Relevance Feedback With Neural Network-Based Word Representations

open access: yesIEEE Access, 2018
In information retrieval, query expansion methods, such as pseudo-relevance feedback, are designed to enrich users' queries with relevant terms for comprehensively interpreting the desired information.
