Recovering Capitalization and Punctuation Marks on Speech Transcriptions
INESC-ID Lisboa and IST and ISCTE –
This presentation addresses two important metadata annotation tasks, involved in the production of rich transcripts: capitalization and recovery of punctuation marks. The main focus of this study concerns broadcast news, using both manual and automatic speech transcripts. Different capitalization models were analysed and compared, indicating that generative approaches capture the structure of written corpora better, while the discriminative approaches are suitable for dealing with speech transcripts, and are also more robust to ASR errors. The so-called language dynamics have been addressed, and results indicate that the capitalization performance is affected by the temporal distance between the training and testing data. In what concerns the punctuation task, this study covers the three most frequent marks: full stop, comma, and question mark. Early experiments addressed full-stop and comma recovery, using local features, and combining lexical and acoustic information. Recent experiments also combine prosodic information and extend this study to question marks.

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.
