The Subject Annotations of the Danish Parliament Corpus (2009-2017) - Evaluated with Automatic Multi-label Classification

no code implementations LREC 2022 Costanza Navarretta, Dorte Haltrup Hansen

The paper also contains an analysis of the subjects in the corpus, and a description of multi-label classification experiments act to verify the consistency of the subject annotation and the utility of the corpus for training classifiers on this type of data.

Identifying Parties in Manifestos and Parliament Speeches

no code implementations LREC 2020 Costanza Navarretta, Dorte Haltrup Hansen

These results are significantly better than the results obtained by the majority classifier (F1-score = 0. 11) and by chance results (0. 25) and show that building language models over the speeches used by politicians can be used to identify the politicians{'} party even if they debate about the same subjects and thus often use the same terminology in many cases.

Creating a Corpus of Gestures and Predicting the Audience Response based on Gestures in Speeches of Donald Trump

no code implementations LREC 2020 Verena Ruf, Costanza Navarretta

The aim of this study is to explore the role of speech pauses and gestures alone as predictors of audience reaction without other types of speech information.

Dialogue Act Annotation in a Multimodal Corpus of First Encounter Dialogues

no code implementations LREC 2020 Costanza Navarretta, Patrizia Paggio

This paper deals with the annotation of dialogue acts in a multimodal corpus of first encounter dialogues, i. e. face-to- face dialogues in which two people who meet for the first time talk with no particular purpose other than just talking.

Automatic identification of head movements in video-recorded conversations: can words help?

no code implementations WS 2017 Patrizia Paggio, Costanza Navarretta, Bart Jongejan

The results of the automatic annotation are evaluated against manual annotations in the same data and show an accuracy of 68{\%} with respect to these.

Mirroring Facial Expressions and Emotions in Dyadic Conversations

no code implementations LREC 2016 Costanza Navarretta

In this study, we want to determine whether the overlapping facial expressions are mirrored or are otherwise correlated in the encounters, and to what extent mirroring facial expressions convey the same emotion.

Transfer learning of feedback head expressions in Danish and Polish comparable multimodal corpora

no code implementations LREC 2014 Costanza Navarretta, Magdalena Lis

However, they also confirm preceding studies that have identified both similarities and differences in the use of feedback head movements in different languages.

Multimodal Behaviour and Feedback in Different Types of Interaction

no code implementations LREC 2012 Costanza Navarretta, Patrizia Paggio

In this article, we compare feedback-related multimodal behaviours in two different types of interactions: first encounters between two participants who do not know each other in advance, and naturally-occurring conversations between two and three participants recorded at their homes.
