This article presents an analysis of the textual complexity of satirical and true news for Brazilian Portuguese. The Fake has been a big problem nowadays. Satirical content is an important point in the automatic detection of false news as its use can cause underlying confusion in the analysis. To carry out this research, the NILC-Metrix tool was applied, and 16 measures were evaluated, including descriptive, syntactic and semantic aspects, noting a greater complexity for real texts.

EMNLP 2021 is planned to be a hybrid event in Punta Cana, Dominican Republic, with both on-site and fully virtual participation possible. The experience for on-site participants would closely approximate a normal pre-COVID *ACL conference, with 5-6 thematically organized parallel sessions and live Q/A and interactive discussion immediately after the talks. Presentations by virtual participants will be equitably interleaved with those of on-site participants, projected on the auditorium screens as if on-site, and also followed immediately by live Q/A and interactive discussion at a time during reasonable waking hours for the virtual presenter. For all participants, on-site and virtual, who are unable to attend a session due to either time-zone issues or because they are participating in another session live, talk recordings and slides will be available online at a minimum after the live presentation (and in many cases before as well), and questions may be submitted in advance on session-specific discussion boards and answered live in session with the usual visual aids if desired.

This work investigates the syntactic-semantic proprieties of the verb “falar” (to speak) of Brazilian Portuguese (BP) in a journalistic corpus and three BP verbal databases (VerbNet.Br, VerboWeb and Verbo-Brasil). The data demonstrate a polyvalence and complexity of “falar”. In addition, concerning the analysis of the databases, it was verified a need for manual reviews, made out by linguists, and/or expansions of the linguistic descriptions, especially when considering the relevance of constructions with the verb "falar" for different applications in the Natural Language Processing area

A propósito do verbo falar no português brasileiro: uma análise em corpus e em bases de dados verbais

Os provérbios são um tipo especial de unidades linguísticas que tem
sido amplamente ignorado pela comunidade de Processamento de Linguagem
Natural (PLN), apesar de levantarem desafios interessantes para o processamento.
Este artigo apresenta o procedimento de integração do Mínimo Paremiológico do Português no sistema STRING e a distribuição desses provérbios
mais usuais em três corpora distintos do português (europeu).

Provérbios portugueses usuais: distribuição em corpora

The annotation of informal texts within the Universal Dependencies framework requires two segmentation processes: definition of the relevant unity for syntactic analysis and identification of syntactic words. In this paper, we present the linguistic idiosyncrasies of DANTEStocks, a corpus of tweets from the financial market, written in Portuguese, and the general guidelines for their automatic segmentation. As such, this work contributes to a better understanding of linguistic aspects of tweets and the development of resources and tools for automatic processing of this subgenre of user-generated content.

Descrição Preliminar do Corpus DANTEStocks: Diretrizes de Segmentação para Anotação segundo Universal Dependencies

Apresentamos a instanciação que realizamos das diretrizes do modelo Universal Dependencies (UD) para a anotação de Numerais em português. Apresentamos as diferenças do conceito da classe de numerais na Nomenclatura Gramatical Brasileira e Portuguesa e nas diretrizes da UD. Apresentamos os principais problemas detectados . Os resultados da combinação das diretrizes da UD com as características dos numerais em português são apresentados em detalhes, com exemplos, juntamente com os argumentos que amparam cada decisão tomada.

Este trabalho apresenta uma proposta para representar computacionalmente as construções Transitiva Indireta, Transitiva Oblíqua e Bitransitiva
do Português Brasileiro, no âmbito do Constructicon da FrameNet Brasil.
Dessa forma, demonstra de que maneira as teorias irmãs da Semântica de Frames e da Gramática das Construções podem contribuir na busca por um modelo
de língua que alie forma e sentido em uma única representação.

Construções de Estrutura Argumental com Argumento Preposicionado: uma modelagem linguístico-computacional na FrameNet Brasil

Este trabalho objetiva apresentar a descrição e a modelagem linguístico-computacional das construções interrogativas QU- do Português brasileiro no Constructicon da FrameNet Brasil.

Apresentamos a proposta de descrição e análise de dados verbais do português brasileiro presente no banco de dados VerboWeb. Os verbos foram agrupados e classificados de acordo com o arcabouço teórico-metodológico da Semântica Lexical, que assume que certas propriedades semânticas dos verbos determinam seu comportamento sintático. Mostramos como o banco de dados é estruturado e as generalizações que podemos fazer sobre o léxico verbal de nossa língua.

In this study, linguistic features were listed for classification of triples,based on a parallel corpus in Galician, Brazilian Portuguese (PT-BR) and European Spanish (EE). In the experiments, at the syntactic level, a relevant per-formance of features that offer greater difficulty to extract valid triples was ob-served, such as the corelated null object/subject and the verb-subject inversion,as well as relational triples that form ungrammatical sub-sentences. At the mor-phological level, it was observed that the grammatical class of the initial wordof each sub-sentence, especially when they are prepositions, were relevant forthe classification of the triples

This article describes a methodology that was developed to review Emocionário, a lexicon of emotion words in Portugese from Linguateca's AC/DC project. This first portion of the review was carried out in seven of the 24 groups of Emocionário, being them “Desespero”, “Esperança”, “Humildade”, “Pena”, “Satisfação”, “Saudade” and “Surpresa”. The methodology is then illustrated, making use of examples taken from the corpus itself for each of the steps. Some of the main changes are documented and discussed at the end.

Descrição de uma metodologia desenvolvida para revisão semiautomática de um léxico de palavras de emoção

Um estudo exploratório de exposição de participantes às variantes de uma variável linguística saliente do ponto de vista social, a palatalização progressiva, foi realizado com o uso de rastreamento ocular, para examinar o processamento da variação linguística. Os resultados mostram que exposição à variante estigmatizada captou a atenção e aumentou a dilatação da pupila dos participantes, o que pode ser interpretado como evidência de uma resposta emocional.
