UO-LouTAL at SemEval-2023 Task 6: Lightweight Systems for Legal Processing
Sébastien Bosch | Louis Estève | Joanne Loo | Anne-Lyse Minard
Proceedings of the 17th International Workshop on Semantic Evaluation (SemEval-2023)

This paper presents the work produced by students of the University of Orlans Masters in Natural Language Processing program by way of participating in SemEval Task 6, LegalEval, which aims to enhance the capabilities of legal professionals through automated systems. Two out of the three sub-tasks available – Rhetorical Role prediction (RR) and Legal Named Entity Recognition (L-NER) – were tackled, with the express intent of developing lightweight and interpretable systems. For the L-NER sub-task, a CRF model was trained, augmented with post-processing rules for some named entity types. A macro F1 score of 0.74 was obtained on the DEV set, and 0.64 on the evaluation set. As for the RR sub-task, two sentence classification systems were built: one based on the Bag-of-Words technique with L-NER system output integrated, the other using a sentence-transformer approach. Rule-based post-processing then converted the results of the sentence classification systems into RR predictions. The better-performing Bag-of-Words system obtained a macro F1 score of 0.49 on the DEV set and 0.57 on the evaluation set.

Proceedings of the Fifth Social Media Mining for Health Applications Workshop & Shared Task

The vast amount of data on social media presents significant opportunities and challenges for utilizing it as a resource for health informatics. The fifth iteration of the Social Media Mining for Health Applications (#SMM4H) shared tasks sought to advance the use of Twitter data (tweets) for pharmacovigilance, toxicovigilance, and epidemiology of birth defects. In addition to re-runs of three tasks, #SMM4H 2020 included new tasks for detecting adverse effects of medications in French and Russian tweets, characterizing chatter related to prescription medication abuse, and detecting self reports of birth defect pregnancy outcomes. The five tasks required methods for binary classification, multi-class classification, and named entity recognition (NER). With 29 teams and a total of 130 system submissions, participation in the #SMM4H shared tasks continues to grow.

Atelier DÉfi Fouille de Textes

Cet article présente le système développé par l’équipe DOING pour la campagne d’évaluation DEFT 2020 portant sur la similarité sémantique et l’extraction d’information fine. L’équipe a participé uniquement à la tâche 3 : “extraction d’information”. Nous avons utilisé une cascade de CRF pour annoter les différentes informations à repérer. Nous nous sommes concentrés sur la question de l’imbrication des entités et de la pertinence d’un type d’entité pour apprendre à reconnaître un autre. Nous avons également testé l’utilisation d’une ressource externe, MedDRA, pour améliorer les performances du système et d’un pipeline plus complexe mais ne gérant pas l’imbrication des entités. Nous avons soumis 3 runs et nous obtenons en moyenne sur toutes les classes des F-mesures de 0,64, 0,65 et 0,61.

IRISA at SMM4H 2018: Neural Network and Bagging for Tweet Classification
Anne-Lyse Minard | Christian Raymond | Vincent Claveau
Proceedings of the 2018 EMNLP Workshop SMM4H: The 3rd Social Media Mining for Health Applications Workshop & Shared Task

This paper describes the systems developed by IRISA to participate to the four tasks of the SMM4H 2018 challenge. For these tweet classification tasks, we adopt a common approach based on recurrent neural networks (BiLSTM). Our main contributions are the use of certain features, the use of Bagging in order to deal with unbalanced datasets, and on the automatic selection of difficult examples. These techniques allow us to reach 91.4, 46.5, 47.8, 85.0 as F1-scores for Tasks 1 to 4.

Actes de la Conférence TALN. Volume 2 - Démonstrations, articles des Rencontres Jeunes Chercheurs, ateliers DeFT

Cet article décrit les systèmes développés par l’équipe LinkMedia de l’IRISA pour la campagne d’évaluation DeFT 2018 portant sur l’analyse d’opinion dans des tweets en français. L’équipe a participé à 3 des 4 tâches de la campagne : (i) classification des tweets selon s’ils concernent les transports ou non, (ii) classification des tweets selon leur polarité et (iii) annotation des marqueurs d’opinion et de l’objet à propos duquel est exprimée l’opinion. Nous avons utilisé un algorithme de boosting d’arbres de décision et des réseaux de neurones récurrents (RNN) pour traiter les tâches 1 et 2. Pour la tâche 3 nous avons expérimenté l’utilisation de réseaux de neurones récurrents associés à des CRF. Ces approches donnent des résultats proches, avec un léger avantage aux RNN, et ont permis d’être parmi les premiers classés pour chacune des tâches.

The Scope and Focus of Negation: A Complete Annotation Framework for Italian
Begoña Altuna | Anne-Lyse Minard | Manuela Speranza
Proceedings of the Workshop Computational Semantics Beyond Events and Roles

In this paper we present a complete framework for the annotation of negation in Italian, which accounts for both negation scope and negation focus, and also for language-specific phenomena such as negative concord. In our view, the annotation of negation complements more comprehensive Natural Language Processing tasks, such as temporal information processing and sentiment analysis. We applied the proposed framework and the guidelines built on top of it to the annotation of written texts, namely news articles and tweets, thus producing annotated data for a total of over 36,000 tokens.

The Event and Implied Situation Ontology (ESO): Application and Evaluation
Roxane Segers | Marco Rospocher | Piek Vossen | Egoitz Laparra | German Rigau | Anne-Lyse Minard
Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC'16)

This paper presents the Event and Implied Situation Ontology (ESO), a manually constructed resource which formalizes the pre and post situations of events and the roles of the entities affected by an event. The ontology is built on top of existing resources such as WordNet, SUMO and FrameNet. The ontology is injected to the Predicate Matrix, a resource that integrates predicate and role information from amongst others FrameNet, VerbNet, PropBank, NomBank and WordNet. We illustrate how these resources are used on large document collections to detect information that otherwise would have remained implicit. The ontology is evaluated on two aspects: recall and precision based on a manually annotated corpus and secondly, on the quality of the knowledge inferred by the situation assertions in the ontology. Evaluation results on the quality of the system show that 50% of the events typed and enriched with ESO assertions are correct.

MEANTIME, the NewsReader Multilingual Event and Time Corpus
Anne-Lyse Minard | Manuela Speranza | Ruben Urizar | Begoña Altuna | Marieke van Erp | Anneleen Schoen | Chantal van Son
Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC'16)

In this paper, we present the NewsReader MEANTIME corpus, a semantically annotated corpus of Wikinews articles. The corpus consists of 480 news articles, i.e. 120 English news articles and their translations in Spanish, Italian, and Dutch. MEANTIME contains annotations at different levels. The document-level annotation includes markables (e.g. entity mentions, event mentions, time expressions, and numerical expressions), relations between markables (modeling, for example, temporal information and semantic role labeling), and entity and event intra-document coreference. The corpus-level annotation includes entity and event cross-document coreference. Semantic annotation on the English section was performed manually; for the annotation in Italian, Spanish, and (partially) Dutch, a procedure was devised to automatically project the annotations on the English texts onto the translated texts, based on the manual alignment of the annotated elements; this enabled us not only to speed up the annotation process but also provided cross-lingual coreference. The English section of the corpus was extended with timeline annotations for the SemEval 2015 TimeLine shared task. The “First CLIN Dutch Shared Task” at CLIN26 was based on the Dutch section, while the EVALITA 2016 FactA (Event Factuality Annotation) shared task, based on the Italian section, is currently being organized.

Apport de la syntaxe pour l’extraction de relations en domaine médical (Contribution of syntax for relation extraction in the medical domain)
Anne-Lyse Minard | Anne-Laure Ligozat | Brigitte Grau
Actes de la 18e conférence sur le Traitement Automatique des Langues Naturelles. Articles longs

Dans cet article, nous nous intéressons à l’identification de relations entre entités en domaine de spécialité, et étudions l’apport d’informations syntaxiques. Nous nous plaçons dans le domaine médical, et analysons des relations entre concepts dans des comptes-rendus médicaux, tâche évaluée dans la campagne i2b2 en 2010. Les relations étant exprimées par des formulations très variées en langue, nous avons procédé à l’analyse des phrases en extrayant des traits qui concourent à la reconnaissance de la présence d’une relation et nous avons considéré l’identification des relations comme une tâche de classification multi-classes, chaque catégorie de relation étant considérée comme une classe. Notre système de référence est celui qui a participé à la campagne i2b2, dont la F-mesure est d’environ 0,70. Nous avons évalué l’apport de la syntaxe pour cette tâche, tout d’abord en ajoutant des attributs syntaxiques à notre classifieur, puis en utilisant un apprentissage fondé sur la structure syntaxique des phrases (apprentissage à base de tree kernels) ; cette dernière méthode améliore les résultats de la classification de 3%.
