O Repositório de Dados de Investigação POLEN DataHub é disponibilizado pela FCCN, serviços digitais FCT – Fundação para a Ciência e a Tecnologia, com o objetivo de promover a abertura e a partilha de dados resultantes de investigação financiada, servindo a comunidade científica nacional.

Esta plataforma está alinhada com a prática da Ciência Aberta e com os princípios FAIR para a gestão de dados de investigação, estando integrada nos serviços abrangidos pelo Programa Nacional de Ciência Aberta e Dados Abertos de Investigação (PNCADAI), financiado pela medida RE-C05-i08 – Ciência Mais Digital, no âmbito do Programa de Recuperação e Resiliência (PRR).

O POLEN DataHub está dividido em duas áreas: a área de Coleções Institucionais (dedicada às entidades aderentes) e a Área Geral (dedicada aos beneficiários FCT sem solução primária: repositório de dados institucional, temático ou Coleção Institucional no POLEN DataHub).

Body Based Affective Computing System: discriminating by gender, age, culture, and environment(Universidade do Algarve)
Jun 22, 2026Universidade do Algarve
Humans are prepared to understand others’ emotional expressions from subtle body movements and facial expressions, changing the way they communicate in function of those interactions. To transit to a “factual” human-machine collaboration, where the machine delivers relevant information and functionalities in a timely and appropriate manner, machine...

Synthetic Speech Detection - Portuguese (SSD-PT)
Jun 8, 2026 - Portuguese synthetic speech detection for public administration
André Miguel Viegas Oliveira; Rafael Geraldo dos Santos; Helder Daniel; José Valente de Oliveira, 2026, "Synthetic Speech Detection - Portuguese (SSD-PT)", https://doi.org/10.57979/UC876E, POLEN DataHub, V1
Este conjunto de dados foi criado para apoiar o desenvolvimento e a avaliação de modelos de deteção de fala sintética para a língua portuguesa. Embora existam muitos conjuntos de dados e estudos focados na língua inglesa, ainda existe uma lacuna significativa de recursos para o português, tanto em termos de disponibilidade de dados como de aplicaçõ...
Portuguese synthetic speech detection for public administration(Universidade do Algarve)
May 28, 2026Universidade do Algarve
A administração pública portuguesa tem vindo a adotar a fala como um dos principais meios de interação com o cidadão. Com o aumento da utilização de sistemas de fala sintética, também conhecida como deepfake áudio quando usada de forma maliciosa, surgem novos desafios na validação da autenticidade das comunicações. Neste contexto, o Artigo 50 do AI...

XRD raw data of geological chert of the Algarve basin
May 13, 2026 - A exploração de matérias-primas siliciosas durante o Paleolítico Superior no sudoeste da Península Ibérica
Neto Belmiro, Joana Filipa, 2026, "XRD raw data of geological chert of the Algarve basin", https://doi.org/10.57979/SDLM4E, POLEN DataHub, V1, UNF:6:vjjgQrl2Ilh/1+qEFKI0aw== [fileUNF]
This study utilised X-ray diffraction (XRD) to determine the mineral composition of 23 geological powdered samples of chert from the Algarve region. Samples were analysed using a Bruker AXS D8 Discover XRD with the Da Vinci design, equipped with a Cu Kα source operating at 40 kV and 40 mA, and a Lynxeye 1D detector. Scans were conducted from 3° to...
