Relação entre acurácia na repetição de palavras e conhecimento lexical em crianças

There is in the literature a divergent description between lexical knowledge and word production accuracy. The aims of this study were: (a) to investigate the influence (effect) of the word lexical knowledge over production accuracy; (b) in case there is, to characterize acoustically this interference. Eight children (5-6 years old) with typical development language participated of this study. The methodological procedure consisted of: (a) survey of the children lexical knowledge concerning to IAFAC’s words; (b) recordings of the IAFAC’s words; (c) identifi cation and characterization of the linguistic cues, by acoustic analysis, in the IAFAC’s word production in function of the different knowledge degrees. Our results suggest a negative correlation (r=-0,13, p=0,000) between lexical knowledge and presence of the linguistics cues in word’s production. However, the linguistics cues refer to hesitative cues instead of phonological errors. Implications of these results for clinical practicing are discussed.

Modelos de recuperação de informação e web semântica: a questão da relevância

Introduction: In the Web environment, there is a need for greater care with regard to the processing of descriptive and thematic information. The concern with the recovery of information in computer systems precedes the development of the first personal computers. Models of information retrieval have been and are today widely used in databases specific to a field whose scope is known. Objectives: Verify how the issue of relevance is treated in the main computer models of information retrieval and, especially, as the issue is addressed in the future of the Web, the called Semantic Web. Methodology: Bibliographical research. Results: In the classical models studied here, it was realized that the main concern is retrieving documents whose description is closest to the search expression used by the user, which does not necessarily imply that this really needs. In semantic retrieval is the use of ontologies, feature that extends the user's search for a wider range of possible relevant options. Conclusions: The relevance is a subjective judgment and inherent to the user, it will depend on the interaction with the system and especially the fact that he expects to recover in your search. Systems that are based on a model of relevance are not popular, because it requires greater interaction and depend on the user's disposal. The Semantic Web is so far the initiative more efficient in the case of information retrieval in the digital environment.

Sintaxe e semântica de registros bibliográficos: princípios para a conversão de registros analógicos para o formato MARC21 bibliográfico: Scan for MARC

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

Ontologias, categorias e interoperabilidade semântica

Explores the concept of interoperability as a means of cooperation, stressing the importance of promoting them from consistent information policies. Highlights the dependence of interoperability to the variations of language that account for sociocultural differences and associates its realization to common ontology construction as a means of enabling structures that can be integrated. Emphasizes the importance of using categories to provide the entire organization and to facilitate access by offering support the process of categorizing on concrete terminologies of specific domains and areas of activity, discourse communities references or of the speeches actually made.

The Automatic Mapping of Princeton WordNet Lexical-Conceptual Relations onto the Brazilian Portuguese WordNet Database

Princeton WordNet (WN.Pr) lexical database has motivated efficient compilations of bulky relational lexicons since its inception in the 1980's. The EuroWordNet project, the first multilingual initiative built upon WN.Pr, opened up ways of building individual wordnets, and interrelating them by means of the so-called Inter-Lingual-Index, an unstructured list of the WN.Pr synsets. Other important initiative, relying on a slightly different method of building multilingual wordnets, is the MultiWordNet project, where the key strategy is building language specific wordnets keeping as much as possible of the semantic relations available in the WN.Pr. This paper, in particular, stresses that the additional advantage of using WN.Pr lexical database as a resource for building wordnets for other languages is to explore possibilities of implementing an automatic procedure to map the WN.Pr conceptual relations as hyponymy, co-hyponymy, troponymy, meronymy, cause, and entailment onto the lexical database of the wordnet under construction, a viable possibility, for those are language-independent relations that hold between lexicalized concepts, not between lexical units. Accordingly, combining methods from both initiatives, this paper presents the ongoing implementation of the WN.Br lexical database and the aforementioned automation procedure illustrated with a sample of the automatic encoding of the hyponymy and co-hyponymy relations.

Léxico e cores: as expressões cromáticas contribuindo para a ampliação lexical

The lexicon is the cultural heritage of a people. It is composed by the linguistic and extra-linguistic experience gained over the years and consists of different systems, among them the lexical set of colors that has collaborated on lexical expansion in common discourse as well as in specialized discourse, providing the interaction and equilibrium among the different levels of specialization of discourse. This work aims at talking about the role of the field of colors in formation of new lexical units in Botany and Zoology, as well as its performance in the intersection between the common and specialized discourse.

A produção lexical de adjetivos no português brasileiro

Ce travail a le but de quantifier les formes les plus courantes d’adjetifs en portuguais brésilien, il s’agit d’un travail qui porte sur les usages synchroniques de la langue. Notre objetif c’est d’indentifier les formations lexicales propres aux adjetifs et de quantifier les usages de ces fomations pour en découvrir les tendances synchroniques de ces usages en portuguais brésilien. Le corpus est de base écrite, composé des lettres des lecteurs de magazine, ce qui permet plus de stabilité pour l’analyse. Vu qu’il s’agit d’un suport d’expression populaire le corpus nous a possibilité de faire un approche au langage plus informelle dont la façon d’expression permet la formation de vocabulaires les plus insolites et les plus récentes, tandis que l’écrite formelle résiste plus aux changements. La recheche des formes nous a donné des résultats quantitatifs des formes déjà connues, les plus nouvelles aussi et des usages des mots appartenants à d’autres classes gramaticales qui avaient une valeur d’adjetive dans quelques contextes spécifiques, en expressions typiques de langage informel. Ce travail, donc, contribue comme um petit portrait de la réalité lexicale brésilienne dans l’usage dynamique de la langue
