Measuring pseudo relevance feedback & CLIR [PDF]

open access: yesProceedings of the 27th annual international ACM SIGIR conference on Research and development in information retrieval, 2004
In this poster, we report on the effects of pseudo relevance feedback (PRF) for a cross language image retrieval task using a test collection. Typically PRF has been shown to improve retrieval performance in previous CLIR experiments based on average precision at a fixed rank.

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 ...

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.

Improved Arabic query expansion using word embedding [PDF]

open access: yesScientific Reports
Word embedding enhances pseudo-relevance feedback query expansion (PRFQE), but training word embedding models takes a long time and is applied to large datasets.

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

On Improving Pseudo-Relevance Feedback Using Pseudo-Irrelevant Documents [PDF]

open access: yes, 2010
Pseudo-Relevance Feedback (PRF) assumes that the top-ranking n documents of the initial retrieval are relevant and extracts expansion terms from them. In this work, we introduce the notion of pseudo-irrelevant documents, i.e. high-scoring documents outside of top n that are highly unlikely to be relevant.

Query dependent pseudo-relevance feedback based on wikipedia [PDF]

open access: yesProceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval, 2009
Pseudo-relevance feedback (PRF) via query-expansion has been proven to be e®ective in many information retrieval (IR) tasks. In most existing work, the top-ranked documents from an initial search are assumed to be relevant and used for PRF. One problem with this approach is that one or more of the top retrieved documents may be non-relevant, which can ...
