Factual Confidence of LLMs: on Reliability and Robustness of Current Estimators

1 code implementation19 Jun 2024 Matéo Mahaut, Laura Aina, Paula Czarnowska, Momchil Hardalov, Thomas Müller, Lluís Màrquez

Our experiments across a series of LLMs indicate that trained hidden-state probes provide the most reliable confidence estimates, albeit at the expense of requiring access to weights and training data.

1 code implementation14 Jun 2022 Chandan K. Reddy, Lluís Màrquez, Fran Valero, Nikhil Rao, Hugo Zaragoza, Sambaran Bandyopadhyay, Arnab Biswas, Anlu Xing, Karthik Subbian

This paper introduces the "Shopping Queries Dataset", a large dataset of difficult Amazon search queries and results, publicly released with the aim of fostering research in improving the quality of search results.

Tailoring and Evaluating the Wikipedia for in-Domain Comparable Corpora Extraction

1 code implementation3 May 2020 Cristina España-Bonet, Alberto Barrón-Cedeño, Lluís Màrquez

Our best metric for domainness shows a strong correlation with the human-judged precision, representing a reasonable automatic alternative to assess the quality of domain-specific corpora.

BookQA: Stories of Challenges and Opportunities

no code implementations2 Oct 2019 Stefanos Angelidis, Lea Frermann, Diego Marcheggiani, Roi Blanco, Lluís Màrquez

We present a system for answering questions based on the full text of books (BookQA), which first selects book passages given a question at hand, and then uses a memory network to reason and predict an answer.

Cross-language Learning with Adversarial Neural Networks: Application to Community Question Answering

no code implementations21 Jun 2017 Shafiq Joty, Preslav Nakov, Lluís Màrquez, Israa Jaradat

We address the problem of cross-language adaptation for question-question similarity reranking in community question answering, with the objective to port a system trained on one input language to another input language given labeled training data for the first language and only unlabeled data for the second language.
