This article presents a statistical study of WPT05, a text corpus derived from a crawl of the Portuguese Web performed in 2005. This corpus is a valuable resource for researchers in Natural Language Processing (NLP). As one of the biggest publicly available collections of European Portuguese texts, we provide statistical analyses of the contents, covering the languages identified, the represent...

The present study is aimed at describing the semantic prosody of equivalent items in English and Portuguese. Semantic prosody is the connotation conveyed by the regular co-occurrence of lexical items, as revealed by the exploration of a computer-readable corpus. Although there are several studies dealing with semantic prosody in English, only one has looked at this issue contrasting English and...

Grapheme to phoneme (GTP) systems for languages such as English, German, and Korean have been shown to achieve better performance rates with the inclusion of a morpho-phonological preprocessing component. While semiautomatic and automatic GTP approaches for Portuguese continue to achieve steady gains, such algorithms do not take morphology into account, despite a growing need to do so, based in...

The purpose of this study was to analyze the path to expertise of Portuguese and USA basketball players according to their specific playing position (i.e. guards, forwards and centers). The information needed to achieve this purpose was collected through a validated questionnaire applied to 75 Portuguese and 45 USA players in the Portuguese League. This questionnaire provided detailed informati...

The present study aimed to investigate the impact of chronic psychosocial stress and resilience, including at a biological level (immune and neuroendocrine function) in Portuguese citizens with psychic anomaly/mental disorder. The sample aggregated 69 participants. It has been used the following psychometric instruments: 21-item depression, anxiety and stress scales (DASS-21), in the Portuguese...

This paper presents a new approach of building a language identification system using a specialized Phone Recognition system followed by Language Modeling (PRLM) to differentiate Portuguese varieties spoken in African Countries from European Portuguese. The system is designed to focus on exploiting the phonotactic information of a single discriminatively trained tokenizer for the specific pair ...

In this paper, we introduce TimeBankPT, a TimeML annotated corpus of Portuguese. It has been produced by adapting an existing resource for English, namely the data used in the first TempEval challenge. TimeBankPT is the first corpus of Portuguese with rich temporal annotations (i.e. it includes annotations not only of temporal expressions but also about events and temporal relations). In additi...

This paper reports the annotation of a Brazilian Portuguese Treebank with semantic role labels following Propbank guidelines. A different language and a different parser output impact the task and require some decisions on how to annotate the corpus. Therefore, a new annotation guide – called Propbank-Br has been generated to deal with specific language phenomena and parser problems. In this ph...

In Portuguese, different strategies for dealing with tune-text accommodation have been reported. However, no systematic research has been conducted exploring crucial cases of complex nuclear melodies realized in nuclear words with final stress, as in yes-no questions. Based on reading and semispontaneous data from ten regions in Brazil and eleven regions in Portugal, this study reveals that Bra...

This paper addresses the topic of knowledge management in multinational companies (MNCs). Its purpose is to examine the role of expatriates in knowledge acquisition and transfer within MNCs. Specifically it focuses on knowledge acquisition and transfer from one MNC head office located in Germany to two Portuguese subsidiaries as a basis for competitive advantage in their Portuguese subsidiaries...
