Developing a large semantically annotated corpus

no code implementations LREC 2012 Valerio Basile, Johan Bos, Kilian Evang, Noortje Venhuizen

What would be a good method to provide a large collection of semantically annotated texts with formal, deep semantics rather than shallow?

Empirical Analysis of Foundational Distinctions in Linked Open Data

1 code implementation26 Mar 2018 Luigi Asprino, Valerio Basile, Paolo Ciancarini, Valentina Presutti

For example, distinctions such as whether an entity is inherently a class or an individual, or whether it is a physical object or not, are hardly expressed in the data, although they have been largely studied and formalised by foundational ontologies (e. g. DOLCE, SUMO).

The paper describes the organization of the SemEval 2019 Task 5 about the detection of hate speech against immigrants and women in Spanish and English messages extracted from Twitter.

Do You Really Want to Hurt Me? Predicting Abusive Swearing in Social Media

no code implementations LREC 2020 Endang Wahyu Pamungkas, Valerio Basile, Viviana Patti

In this study, we explore the phenomenon of swearing in Twitter conversations, taking the possibility of predicting the abusiveness of a swear word in a tweet context as the main investigation perspective.

Multilingual Irony Detection with Dependency Syntax and Neural Models

1 code implementation COLING 2020 Alessandra Teresa Cignarella, Valerio Basile, Manuela Sanguinetti, Cristina Bosco, Paolo Rosso, Farah Benamara

This paper presents an in-depth investigation of the effectiveness of dependency-based syntactic features on the irony detection task in a multilingual perspective (English, Spanish, French and Italian).

Toward a Perspectivist Turn in Ground Truthing for Predictive Computing

no code implementations9 Sep 2021 Valerio Basile, Federico Cabitza, Andrea Campagner, Michael Fell

Most Artificial Intelligence applications are based on supervised machine learning (ML), which ultimately grounds on manually annotated data.

SemEval-2023 Task 11: Learning With Disagreements (LeWiDi)

no code implementations28 Apr 2023 Elisa Leonardelli, Alexandra Uma, Gavin Abercrombie, Dina Almanea, Valerio Basile, Tommaso Fornaciari, Barbara Plank, Verena Rieser, Massimo Poesio

We report on the second LeWiDi shared task, which differs from the first edition in three crucial respects: (i) it focuses entirely on NLP, instead of both NLP and computer vision tasks in its first edition; (ii) it focuses on subjective tasks, instead of covering different types of disagreements-as training with aggregated labels for subjective NLP tasks is a particularly obvious misrepresentation of the data; and (iii) for the evaluation, we concentrate on soft approaches to evaluation.

Litescale: A Lightweight Tool for Best-worst Scaling Annotation

no code implementations RANLP 2021 Valerio Basile, Christian Cagnazzo

Best-worst Scaling (BWS) is a methodology for annotation based on comparing and ranking instances, rather than classifying or scoring individual instances.

We Need to Consider Disagreement in Evaluation

no code implementations ACL (BPPF) 2021 Valerio Basile, Michael Fell, Tommaso Fornaciari, Dirk Hovy, Silviu Paun, Barbara Plank, Massimo Poesio, Alexandra Uma

Instead, we suggest that we need to better capture the sources of disagreement to improve today’s evaluation practice.

Italian NLP for Everyone: Resources and Models from EVALITA to the European Language Grid
