Can we predict QPP? An approach based on multivariate outliers

no code implementations7 Feb 2024 Adrian-Gabriel Chifu, Sébastien Déjean, Moncef Garouani, Josiane Mothe, Diégo Ortiz, Md Zia Ullah

Query performance prediction (QPP) aims to forecast the effectiveness of a search engine across a range of queries and documents.

Selective Query Processing: a Risk-Sensitive Selection of System Configurations

no code implementations17 May 2023 Josiane Mothe, Md Zia Ullah

To determine the ideal configurations to use on a per-query basis in real-world systems we developed a method in which a restricted number of possible configurations is pre-selected and then used in a meta-search engine that decides the best search configuration on a per query basis.

Effectiveness and Efficiency Trade-off in Selective Query Processing

no code implementations22 Feb 2023 Josiane Mothe, Md Zia Ullah

In this paper, we examine selective query processing in different settings, both in terms of effectiveness and efficiency; this includes selective query expansion and other forms of selective query processing (e. g., when the term weighting function varies or when the expansion model varies).

iQPP: A Benchmark for Image Query Performance Prediction

1 code implementation20 Feb 2023 Eduard Poesina, Radu Tudor Ionescu, Josiane Mothe

To date, query performance prediction (QPP) in the context of content-based image retrieval remains a largely unexplored task, especially in the query-by-example scenario, where the query is an image.

Forward and Backward Feature Selection for Query Performance Prediction

no code implementations4 Dec 2019 Sébastien Déjean, Radu Tudor Ionescu, Josiane Mothe, Md Zia Ullah

We found that: (1) our model based on a limited number of selected features is as good as more complex models for QPP and better than non-selective models; (2) our model is more efficient than complex models during inference time since it requires fewer features; (3) the predictive model is readable and understandable; and (4) one of our new QPP features is consistently selected across different collections, proving its usefulness.
