Opening up Minds with Argumentative Dialogues

no code implementations16 Jan 2023 Youmna Farag, Charlotte O. Brand, Jacopo Amidei, Paul Piwek, Tom Stafford, Svetlana Stoyanchev, Andreas Vlachos

We show that while both models perform closely in terms of opening up minds, the argument-based model is significantly better on other dialogue properties such as engagement and clarity.

Identifying Annotator Bias: A new IRT-based method for bias identification

no code implementations COLING 2020 Jacopo Amidei, Paul Piwek, Alistair Willis

Our interpretation of IRT offers an original bias identification method that can be used to compare annotators{'} bias and characterise annotation disagreement.

Rethinking the Agreement in Human Evaluation Tasks

no code implementations COLING 2018 Jacopo Amidei, Paul Piwek, Alistair Willis

For this reason, we believe that annotation schemes for natural language generation tasks that are aimed at evaluating language quality need to be treated with great care.

A syllogistic system for propositions with intermediate quantifiers

no code implementations18 May 2018 Pasquale Iero, Allan Third, Paul Piwek

This paper describes a formalism that subsumes Peterson's intermediate quantifier syllogistic system, and extends the ideas by van Eijck on Aristotle's logic.

Negation

Measuring Non-cooperation in Dialogue

no code implementations COLING 2016 Brian Pl{\"u}ss, Paul Piwek

In contrast, we start from rules for normal/correct dialogue behaviour - i. e., a dialogue game - which in principle can be derived from a corpus of cooperative dialogues, and provide a quantitative measure for the degree to which participants comply with these rules.
