Context-Driven Interactive Query Simulations Based on Generative Large Language Models

1 code implementation15 Dec 2023 Björn Engelmann, Timo Breuer, Jana Isabelle Friese, Philipp Schaer, Norbert Fuhr

The proposed query generation methods build upon recent Large Language Model (LLM) approaches and consider the user's context throughout the simulation of a search session.

UNDR: User-Needs-Driven Ranking of Products in E-Commerce

no code implementations13 Feb 2023 Andrea Papenmeier, Daniel Hienert, Firas Sabbah, Norbert Fuhr, Dagmar Kern

As a user-centered approach that does not rely on post-purchase ratings or reviews, our method bypasses the cold-start problem while still reflecting the needs of an average customer.

Response to Moffat's Comment on "Towards Meaningful Statements in IR Evaluation: Mapping Evaluation Measures to Interval Scales"

no code implementations22 Dec 2022 Marco Ferrante, Nicola Ferro, Norbert Fuhr

Moffat's comments build on: (i) misconceptions about the representational theory of measurement, such as what an interval scale actually is and what axioms it has to comply with; (ii) they totally miss the central concept of meaningfulness.

Towards Meaningful Statements in IR Evaluation. Mapping Evaluation Measures to Interval Scales

no code implementations7 Jan 2021 Marco Ferrante, Nicola Ferro, Norbert Fuhr

Recently, it was shown that most popular IR measures are not interval-scaled, implying that decades of experimental IR research used potentially improper methods, which may have produced questionable results.

How to Measure the Reproducibility of System-oriented IR Experiments

1 code implementation26 Oct 2020 Timo Breuer, Nicola Ferro, Norbert Fuhr, Maria Maistro, Tetsuya Sakai, Philipp Schaer, Ian Soboroff

Replicability and reproducibility of experimental results are primary concerns in all the areas of science and IR is not an exception.
