EXPRESS – Expression and Recognition of Irony in Multicultural Social Media
Filipe Nuno Marques Pires da Silva,
The main goal of this project is to systematically analyze the expression of irony and sarcasm in social media, in a cross-lingual and multicultural perspective, aiming at its automatic detection.
Automating the detection of irony and sarcasm is yet an unsolved problem. Previous efforts to achieve this aim have been limited in their approach, tending to focus on shallow textual cues indicative of ironic intent. Research has not systematically explored specific linguistic patterns and rhetorical strategies typically used to express verbal and situational irony in text. Moreover, previous studies usually consider these phenomena as a whole, instead of analyzing independently the mechanisms involved in expressing it.
This project aims to answer the following open research questions that are critical to improving irony and sarcasm detection in text mining activities:
i. In social media content, are the linguistic and extra-linguistic mechanisms used to express irony and sarcasm language-dependent?
ii. To what extent does irony expression and representativeness differ across domains, geographical regions, and targets involved?
iii. Which are the most representative linguistic and extra-linguistic devices used to express irony in different types of domains and topics?
iv. How reliable are individuals with respect to identifying and processing ironic messages?
v. Which rhetorical devices are easier to recognize, and which ones are particularly hard to detect, especially by humans not sharing the same cultural and pragmatic context?
vi. Which types of approaches best suit the automatic detection of irony and sarcasm in text? Are we capable of training shallow models to learn these phenomena? Or should we explicitly explore contextual and linguistic information, using advanced NLP strategies?
The main results achieved in the scope of this project will be presented by:
– Paula Carvalho: Identifying Situational Irony in News Headlines
– Sílvio Moreira: Modelling context with user embeddings for sarcasm detection in social media
– Filipe Silva: Computational Detection of Irony in Textual Messages

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
