Resumo: | HPSG is a lexicalist grammatical theory that proposes the parallel formalization of morphosyntactic and semantic structures. This work describes the computational implementation of verbal valences in a new Portuguese grammar in this formalism. This grammar is relevant not only for text understanding applications, but also represents a contribution to the formal documentation of the structures of the language, standing out for its treatment of control and raising constructions. The grammar has been incrementally implemented through its application to increasingly comprehensive test suites. With 278 entries and a total of 215 lemmas, the verb lexicon is still small. However, the proposed type hierarchy models the properties of 118 valence classes, of which 57 are types that encode verb classes. The grammar analyzes 94% of a total of 581 grammatical sentences, while showing low hypergeneration in a set of 167 ungrammatical examples. |

Este trabalho descreve a implementação computacional de valências verbais numa nova gramática do português nesse formalismo. Essa gramática é relevante não somente para aplicações de compreensão textual, mas representa também uma contribuição à documentação formal das estruturas da língua, destacando-se pelo tratamento das construções de controle e alçamento. A gramática tem sido implementada incrementalmente por meio da sua aplicação a conjuntos de teste cada vez mais abrangentes. Com 278 entradas e um total de 215 lemas, o léxico verbal ainda é pequeno. No entanto, a hierarquia de tipos proposta modela as propriedades de 118 classes valenciais, das quais 57 são tipos que codificam classes de verbos. A gramática analisa 94% de um total de 581 sentenças gramaticais, apresentando, ao mesmo tempo, baixa hipergeração em um conjunto de 167 exemplos agramaticais.PP/UFU2022-09-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://seer.ufu.br/index.php/dominiosdelinguagem/article/view/6413210.14393/DL52-v16n4a2022-6Domínios de Lingu@gem; Vol. 16 No. 4 (2022): The computational treatment of Brazilian Portuguese; 1339-1400Domínios de Lingu@gem; Vol. 16 Núm. 4 (2022): El tratamiento computacional del portugués brasileño; 1339-1400Domínios de Lingu@gem; v. 16 n. 4 (2022): Tratamento Computacional do Português Brasileiro; 1339-14001980-5799reponame:Domínios de Lingu@geminstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/dominiosdelinguagem/article/view/64132/33569https://seer.ufu.br/index.php/dominiosdelinguagem/article/view/64132/35231Copyright (c) 2022 Leonel Figueiredo de Alencar, Alexandre Rademakerhttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccess Alencar, Leonel Figueiredo deRademaker, Alexandre2022-12-09T17:41:33Zoai:ojs.www.seer.ufu.br:article/64132Revistahttps://seer.ufu.br/index.php/dominiosdelinguagemPUBhttps://seer.ufu.br/index.php/dominiosdelinguagem/oairevistadominios@ileel.ufu.br||1980-57991980-5799opendoar:2022-12-09T17:41:33Domínios de Lingu@gem - Universidade Federal de Uberlândia (UFU)false |
