A homonímia no português: tratamento semântico segundo a estrutura Qualia de Pustejovsky com vistas a implementações computacionais

No presente trabalho, apresentamos uma proposta de tratamento semântico de formas ambíguas do português do Brasil, no caso, lexias homógrafas, com o escopo de oferecermos estratégias lingüísticas para a sua implementação computacional em Sistemas de Processamento das Línguas Naturais (SPLN). O Léxico Gerativo de Pustejovsky foi usado como modelo teórico. Nesse modelo, a Estrutura Qualia - EQ (e os papéis Formal, Télico, Agentivo e Constitutivo) foi selecionada como um dos expedientes lingüístico-semânticos para a realização da desambiguação das formas homônimas. Para que os dados analisados e tratados pudessem ser manipulados, elaboramos uma Base de Conhecimento Lexical (BCL) cujo repertório lingüístico possui seus itens lexicais correlacionados e interligados por diferentes tipos de relações semânticas presentes na EQ.

Aplicação de redes NeuroFuzzy ao processamento de peças automotivas por meio de injeção de polímeros

The injection molding of automotive parts is a complex process due to the many non-linear and multivariable phenomena that occur simultaneously. Commercial software applications exist for modeling the parameters of polymer injection but can be prohibitively expensive. It is possible to identify these parameters analytically, but applying classical theories of transport phenomena requires accurate information about the injection machine, product geometry, and process parameters. However, neurofuzzy networks, which achieve a synergy by combining the learning capabilities of an artificial neural network with a fuzzy set's inference mechanism, have shown success in this field. The purpose of this paper was to use a multilayer perceptron artificial neural network and a radial basis function artificial neural network combined with fuzzy sets to produce an inference mechanism that could predict injection mold cycle times. The results confirmed neurofuzzy networks as an effective alternative to solving such problems.

Processos de leitura em escolares com transtorno do déficit de atenção/hiperatividade

This study aimed to characterize and compare the performance of students with Attention Deficit Hyperactivity Disorder and students with good academic performance on the readingassessment processes. Forty students ranging from 8 years and 2 months old to 10 years and 11 months old, from both genders, from 1st to 4th grades of elementary level, participated inthis study, distributed in two groups: GI, with 20 students with interdisciplinary diagnosis ofAttention Deficit Hyperactivity Disorder (ADHD), and GII, 20 students with good academic performance,paired with GI according to gender, age and school level. The students wereassessedthrough the Brazilian adaptation of the Assessment Process of Reading – PROLEC, composedof four blocks: identification of letters, lexical, syntactic and semantic processes. Statisticallysignificant difference occurred between GI and GII in the PROLEC tests, with the exception of thesame-different and lexical decision tests, indicating that the students from GI presented inferior performance when compared with students from GII. Regarding the classification of the resultsof PROLEC, there was a statistically significant difference in the lexical, syntactic and semanticprocesses and the letter and sound test, with the exception of same-different tests of identificationof letters process. The findings suggests that the group of students with ADHD showsinferior performance compared to the group without disabilities, highlighting that the attentionfactor affects the cognitive functions impairing the acquisition of skills necessary for reading.

Desempenho de escolares com dislexia e transtorno do déficit de atenção e hiperatividade nos processos de leitura

This study aimed to characterize and to compare the performance of students with an interdisciplinary diagnosis of dyslexia and attention deficit hyperactivity disorder (ADHD) in students with good academic performance on the reading processes. Sixty students from both genders, from 2nd to 4th grades of municipal public schools in Marília - SP participated in this study, they were distributed as follows: GI, 20 students with interdisciplinary diagnosis of dyslexia; GII, 20 students with ADHD and GIII, 20 students with good academic performance, paired according to gender, age and grade level with GI and GII. The students were submitted to the application of the assessment of reading processes (PROLEC) composed by four processes: letters identification, lexical, syntactical and semantic. The results highlighted that the students of GIII showed superior performance comparing with GI and GII. There was difference between GI and GII only in low frequency word reading and non words reading of the lexical process. The inferior performance from GI and GII in the PROLEC tests can be justified by the difficulty on the coding and decoding abilities. In ADHD students this difficulty was due to impaired interaction between the visual, linguistic, attention and auditory processing and in the dyslexic students was due to failure at the phonological mediation process, which depends on the knowledge of rules of grapheme - phoneme conversion to the acquisition of word reading. These changes affect the reading achievement and the comprehension of the read text.

Sobre o pensamento de Peirce e a organização da informação e do conhecimento

Incomplete glimpses of the philosophy of Charles Peirce (1839-1914) can frequently be found in studies about Semiotics and Information Science. Therefore, we sought to discover the theoretical and applied interrelationships between knowledge and information organization and Peirce's Semiotics and Philosophy. The aim was to discover and evaluate the contributions of Peirce's Semiotics and Philosophy to the knowledge and information organization field. The method of this study was bibliographical research. The main results were: indexing process semiotic model, semiotic knowledge organization, interaction between documentary semiotics and documentary languages, kinds of inference to the indexing process, as well as the collaboration of Peirce's pragmatism to terminology theory. Finally, we listed issues for future research.
