The Albayzin 2010 Language Recognition Evaluation (LRE), carried out from June to October 2010, was the second effort made by the Spanish/Portuguese community for benchmarking language recognition technology. As the Albayzin 2008 LRE, it was coordinated by the Software Technology Working Group of the University of the Basque Country, with the support of the Spanish Thematic Network on Speech Te...

The development and evaluation of large vocabulary, speaker-independent continuous speech recognition systems are mainly done for the American English language. In this paper we present the work done to date in the development of an hybrid large vocabulary, speaker-independent continuous speech recognition system for the European Portuguese language. Due to the lack of a large appropriate speec...

The Japanese language is represented by two different codes: syllabic and logographic while Portuguese employs an alphabetic writing system. Studies on bilingual Portuguese-Japanese individuals with acquired dyslexia therefore allow an investigation of the interaction between reading strategies and characteristics of three different writing codes. The aim of this study was to examine the differ...

The Spoken Portuguese: Geographic and Social Varieties project has as its main goal the Portuguese teaching as foreign language. The idea is to provide a collection of authentic spoken texts and to make it friendly usable. Therefore, a selection of spontaneous oral data was made, using either already compiled material or material recorded for this purpose. The final corpus constitution resulted...

The semantic annotation of corpora has an important role to play in ensuring that sentences occurring in natural language texts are correctly understood based on their intended context. Two examples of lexical semantic units that contribute to this knowledge are word senses – which allow words with multiple meanings to be understood based on the context in which they are used – and named entiti...

Stemming algorithms are traditionally used in Information Retrieval with the goal of enhancing recall, as they conflate the variant forms of a word into a common representation. This paper describes the development of a simple and eflective su&?x-stripping algorithm for Portuguese. The stemmer is evaluated using a method proposed by Paice f9/. The results show that it performs significantly bet...

This work addresses two metadata annotation tasks, involved in the production of rich transcripts: automatic capitalization, and punctuation marks recovery. The main focus concerns broadcast news, using both manual and automatic speech transcripts. Different capitalization models were analysed and compared, and results support the ideia that generative approaches capture the structure of writte...

Regarding the education of deaf students (in Brazil), three conditions have to be met in order to bring qualitative reasoning (QR) models into the classroom: (a) a bilingual education should be provided, the Brazilian Sign Language (LIBRAS) being the first and Portuguese the second language; (b) in the absence of scientific vocabulary in LIBRAS, it has to be created; (c) given the aural impairm...
