Luísa Coheur

From L²F

Luísa Coheur

Luísa Coheur graduated in Applied Mathematics and Computation and has a MSc degree both from IST. In 2001, she became a member of the newly created L2F and, in 2004, she concluded her PhD degree in Computer Science from both IST and Université Blaise-Pascal. She has been a lecturer at IST since March 2006. Her research areas move from Question Answering (QA) to Machine Translation (MT) and Dialogue Systems. She was the PI of PT-STAR, a project within the Carnegie Mellon/Portugal program that targeted Speech-to-Speech MT. She was also the INESC-ID PI of the FALACOMIGO project, where Edgar, an Embodied Conversational Agent that answers questions about Monserrate Palace, was developed. Luisa Coheur is also a part-time writer. She has 3 published books – Sete histórias por acontecer (2001), Acabou-se! (2001) and E-medo (2007) – and two short stories in the books A República nunca existiu (2008) and O Mensageiro das Estrelas (2012). Both Acabou-se and E-medo won literature prizes.
