  • HATE COVID-19.PT: a project that will automatically detect online hate speech in Portuguese

    HATE COVID-19.PT: a project that will automatically detect online hate speech in Portuguese

    Direct verbal insults. Offensive and insulting words with intent to depreciate. Physical threats to the lives of others or their families. Statistics show that Covid-19 has led to an increase in hate speech.

    Several European and international institutions have issued recommendations on combating racism, xenophobia and homophobia, also alerting to the low level of report and participation. Covid-19 has led to an increase in hate speech towards already vulnerable communities. In response to this problem, FCT – Fundação para a Ciência e a Tecnologia, created a special support – “Impact of the COVID-19 pandemic in the crimes of incitement to hatred and violence and in hate speech”. One of the projects selected includes a Técnico/INESC-ID research team, led by professor Paula Carvalho (Department of Computer Science and Engineering – DEI).

    The main objective of the project “HATE COVID-19.PT -Detecting Overt and Covert Hate Speech in Social Media” is to automatically detect online hate speech in Portuguese. “On the one hand, it is a priority to invest in languages such as Portuguese, whose linguistic resources for mapping hate speech are still quite scarce”, explains professor Paula Carvalho. “On the other hand, we intend to analyse this phenomenon in the Portuguese online community, taking into account the temporal dimension, in order to understand the impact of the pandemic on hate speech, on social networks”, adds the professor.

    The research team intends to study the dynamics of this phenomenon in a specific context, that is why the analysis of hate speech will focus on the pandemic period. “This project will be crucial to assess whether, in fact, the current circumstances have significantly boosted this phenomenon”, and to identify the main targets of hate speech in Portugal, in pandemic times.

    The project, which started on 1st May, will last 10 months and results from a partnership between INESC-ID (proponent entity), Lusa News Agency and the Portuguese National Cybersecurity Center (CNCS). The project has received a total funding of €35,892.

    This project involves the creation of a large annotated corpus from social media, covering the Covid-19 pandemic, which will support the development of a machine learning prototype to detect hate speech and assess its explicitness and intensity, considering the time period and geolocation data. “This prototype will be available to the community, and it can be explored by linguists, communication and social sciences experts, media professionals, among others, in order to monitor, analyse and assess the evolution of hate speech on social media”, says the DEI professor.

    The importance of enhancing the Portuguese language in this field

    The research team involved in “HATE COVID-19.PT” has been focusing on issues that are directly or indirectly related to hate speech, more precisely “irony detection in the media” and, more recently, “the identification of strategies for detecting misinformation, in general, and on social media, in particular”, says professor Paula Carvalho.

    According to the INESC-ID researcher “most studies have focused on direct hate speech, usually including insulting words or expressions”. “Users often express themselves – in an indirect or underhanded way – through linguistic and rhetorical strategies, which difficult speech explicitness”, stresses the Técnico professor.

    “Our team brings together multidisciplinary researchers: natural language processing, artificial intelligence and communication sciences”, says professor Paula Carvalho.

    In addition to professor Paula Carvalho, who is a linguist and works with natural language processing, other INESC-ID scientists are involved in natural language processing and artificial intelligence, as well as a social scientist/DEI professor with an interest in digital media and man machine interaction. Some of these researchers are currently involved in the Contrafake project.

    Knowledge is a major weapon against hate speech

    According to ECRI annual report 2020, racism, racial discrimination and intolerance are growing. “I believe that knowledge is the most effective response to prevent these phenomena”, highlights the INESC-ID researcher. “Therefore, these initiatives promoting research and the advancement of knowledge in such crucial areas are essential to stop this type of crime”, she adds.

    Although the project has an exploratory nature, the team is confident “the results will allow the academic community to monitor and deepen the progress of hate speech, thus promoting the development of research in various areas that focus on this issues”. “In our opinion, the analysis of subsequent studies may guide policy makers and protect the most affected groups”, adds the professor.

    SparCity: the new collaborative project to create a supercomputing framework

    SparCity, a new EuroHPC Joint Undertaking project, was launched.

    The project aims to build a sustainable exascale ecosystem and increasing Europe’s competitiveness.

    The project involves six player organisations in the area of high-performance computing from Portugal, Germany, Norway and Turkey.

    Recently funded by the European High Performance Computing Joint Undertaking (EuroHPC JU), the highly ranked SparCity just launched. With three years of duration and a total budget of 2.6M€, this collaborative project between 6 partners in 4 countries aims to build a sustainable exascale ecosystem and increase Europe’s competitiveness.

    The main goal of SparCity is to create a supercomputing framework that will provide efficient algorithms and coherent tools specifically designed for maximising the performance and energy efficiency of sparse computations on emerging High Performance Computing systems, while also opening up new usage areas for sparse computations in data analytics and deep learning.

    “When talking about sparse computations, people think of scientific applications, finite element methods, mesh computation, etc. However, this project will also open up new usage areas for sparse computation, including data analytics and deep learning. That is why it is a very impactful project.” says Dr Didem Unat, the coordinator of SparCity at Koç University.

    To demonstrate the effectiveness, societal impact, and usability of the framework, the SparCity project will enhance the computing scale and energy efficiency of four challenging real-life applications that come from drastically different domains, namely, computational cardiology, social networks, bioinformatics and autonomous driving. By targeting this collection of challenging applications, SparCity will develop world-class, extreme-scale and energy-efficient HPC technologies.

    SparCity involves partnerships with Sabanci Universitesi (Turkey), Simula Research Laboratory (Norway), INESC-ID (Portugal), Ludwig-Maximilians-Universitaet Muenchen (Germany) and Graphcore (Norway), with the coordination of Koç University (Turkey).

    “For INESC-ID, SparCity will leverage the efforts on the European low power processing technologies (in particular the European Processor Initiative) and contribute to the realisation of future exascale system architectures based on such technologies” says Prof. Leonel Sousa, Full Professor of the Electrical and Computer Engineering Department of Instituto Superior Técnico, University of Lisbon, and Senior Researcher of the High-Performance Computer Architectures and Systems Research Group.

    “It is thus a great opportunity for researchers at Simula to collaborate with internationally leading experts, through these EuroHPC projects, to bring innovative use of HPC to real-world applications.” says Professor Xing Cai, head of the High Performance Computing department at Simula.

    This is an excellent chance for my team at Sabancı University to share our expertise on HPC and work with great researchers on a challenging project which will hopefully change the way we handle extreme-scale problems using sparse data.” says Dr. Kamer Kaya, from Sabancı University.

    Graphcore is committed to enabling next-generation techniques in AI compute, including innovative approaches to sparsity. Putting new hardware and software tools into the hands of researchers through the SparCity initiative will drive a virtuous cycle of discovery and deployment throughout Europe.” says says Ola Tørudbakken, GM & SVP Systems at Graphcore.

  • António Menezes Leitão honored with the Sasada Prize 2021

    António Menezes Leitão honored with the Sasada Prize 2021

    The 2021 Sasada Prize has been awarded to the INESC-ID researcher António Menezes Leitão. António is a senior researcher of the Graphics and Interaction Group at INESC-ID and Professor at Instituto Superior Técnico.

     

    “I had very good teachers but one of them changed my life: Prof. João Pavão Martins became my mentor and he inspired me to follow his example. Just like he did to me, I have challenged my students to become members of my research group and I have tried to be a good mentor. This prize, honoring Prof. Tsuyoshi Sasada, is thus very meaningful to me, as it tells me that I succeeded in that mission. Obviously, the merit also goes to my students. Through their dedication and friendship, they made it very easy to be a mentor”, mentioned António Menezes Leitão about this recognition.

     

    From 2019, the Sasada Prize follows the discontinued Sasada Award (awarded from 2007 until 2016), which was instituted in the memory of Prof. Tsuyoshi Sasada (1941-2005), former Professor of Osaka University, co-founder and Fellow of CAADRIA, a prolific researcher and teacher from whose lab over 200 students have graduated, and better known as “Tee” in the community.

     

    The recipient of this prize is recognized for his sustained record of contributions and their mentoring of others in the research community, demonstrating a significant and lasting impact on computer aided design research. Nominations are called from across the world and this year a rich set was received.

     

    In making its award, the committee was impressed by the focus of António’s research, the quality of his contributions and, in particular, with the significant number of his research students whom he has supported to attend research conferences widely as they establish themselves in the research community. The committee members can recall the high quality of papers and presentations in these sessions over the years.

     

    “My work is focused on the development of theories, techniques, and tools that support architects and engineers in the exploration of algorithmic approaches. These approaches can considerably improve the design process and promote the search for better-performing design solutions but require a significant shift in the way we think about design problems. Throughout the years, I have invited students of architecture, engineering, and computer science to help me advance these ideas and, together, we have been producing a lot of interesting research. The Sasada Prize is the recognition, from the CAADRIA community, that this collaboration has been successful and that my students are now part of a new generation of researchers”, add the INESC-ID Researcher.

     

    The committee has heard from a number of these students who consistently report that he is a committed teacher that is highly sought after and that he is a valued mentor. He has established the research group Algorithm Design for Architecture that welcomes participation from students and young researchers that has developed a strong community committed to design and computation research.

     

    The awarding committee was composed by Atsuko Kaga (Osaka University), Candy Herr (CAADRIA President) and Tom Kvan (CAADRIA Fellow).

  • Detecção de COVID-19 a partir de tosse e fala

    Detecção de COVID-19 a partir de tosse e fala

    Projeto de Investigação para detecção da COVID-19 a partir de tosse e fala

    E se fosse possível saber se alguém está infetado com coronavirus apenas através dos sons que produz a tossir ou ao falar?

    Graças a algoritmos de Inteligência Artificial, em breve pode tornar-se realidade. É este o objetivo do projeto “Deteção de COVID-19 a partir da tosse e fala”, desenvolvido por uma equipa de investigadores do INESC-ID e do Instituto Superior Técnico.

    A fala é produzida por órgãos partilhados com o aparelho respiratório e vários estudos têm demonstrado que é possível detectar certas patologias analisando os sons que o ser humano produz ao falar ou tossir. É com base nesta perspetiva que se dá início a esta investigação.

    Objetivo do Projeto

    Explorar a possibilidade de detectar automaticamente a COVID-19 a partir de seus efeitos na tosse e na fala.

    Para tal, é necessário recolher um extenso conjunto de dados com exemplos representativos de tosse e fala de indivíduos infectados com COVID-19 e saudáveis. A sua participação é imprescindível e muito apreciada.

    Como participar?

    Basta preencher um questionário que demorará aproximadamente 5 minutos. Começaremos por perguntar algumas informações demográficas e de saúde. A seguir, pedir-lhe-emos para gravar audios enquanto realiza alguns exercícios simples de fala.

    A participação é totalmente anónima e confidencial, não sendo recolhidos quaisquer contactos.

    Pode aceder também através do seguinte código QR.

    Quem pode participar?

    Qualquer pessoa. Quer já tenha sido diagnosticada com COVID-19 ou não, saudável ou com outras patologias associadas.

    A participação no estudo é gratuita e totalmente anónima e confidencial.
