Characterizing Information Seeking Processes with Multiple Physiological Signals

1 code implementation1 May 2024 Kaixin Ji, Danula Hettiachchi, Flora D. Salim, Falk Scholer, Damiano Spina

Information access systems are getting complex, and our understanding of user behavior during information seeking processes is mainly drawn from qualitative methods, such as observational studies or surveys.

Online and Offline Evaluation in Search Clarification

no code implementations14 Mar 2024 Leila Tavakoli, Johanne R. Trippas, Hamed Zamani, Falk Scholer, Mark Sanderson

The effectiveness of clarification question models in engaging users within search systems is currently constrained, casting doubt on their overall usefulness.

MIMICS-Duo: Offline & Online Evaluation of Search Clarification

no code implementations9 Jun 2022 Leila Tavakoli, Johanne R. Trippas, Hamed Zamani, Falk Scholer, Mark Sanderson

Asking clarification questions is an active area of research; however, resources for training and evaluating search clarification methods are not sufficient.

Evaluating Fairness in Argument Retrieval

2 code implementations23 Aug 2021 Sachin Pathiyan Cherumanal, Damiano Spina, Falk Scholer, W. Bruce Croft

In this work, we analyze a range of non-stochastic fairness-aware ranking and diversity metrics to evaluate the extent to which argument stances are fairly exposed in argument retrieval systems.
