No âmbito do Processamento Automático de Línguas Naturais (PLN), o desenvolvimento de recursos léxico-semânticos é premente. Ao conceber os sistemas de PLN como um exercício de engenharia da linguagem humana, acredita-se que o desenvolvimento de tais recursos pode ser beneficiado pelos modelos de representação do conhecimento, desenvolvidos pela Engenharia do Conhecimento. Esses modelos, em particular, fornecem simultaneamente o arcabouço teórico-metodológico e a metalinguagem formal para o tratamento computacional do significado das unidades lexicais. Neste artigo, após a apresentação da concepção linguístico-computacional de léxico, elucidam-se os principais paradigmas de representação do conhecimento, enfatizando a abordagem do significado e a metalinguagem formal vinculadas a cada um deles.

O presente trabalho almeja expor o fenômeno da homonímia no português do Brasil, enquanto ambigüidade presente em uma língua natural, por meio de uma revisitação teórica em diversos autores e em confronto com a polissemia. Ademais, pretende-se, além de redefinir conceitualmente a homonímia, propor critérios semânticos distintivos para esse fenômeno lingüístico, tais como a análise sêmica, o campo léxico, o uso de expressões cristalizadas e a ocorrência de traços especificadores.

O objetivo principal deste trabalho foi propor uma reflexão sobre o processo a ser utilizado para a elaboração de um léxico bilíngüe na subárea de cardiologia. Para tanto, tomamos como base os conceitos dos estudos da tradução baseados em corpus, da lingüística de corpus e da terminologia. Como material para compor os corpora utilizamos artigos de cardiologia escritos em português e traduzidos para o inglês, assim como artigos originalmente escritos em português e em inglês. Com base no léxico proposto, pudemos notar algumas diferenças e algumas correspondências de uso entre os termos que aparecem no subcorpus de estudo de textos originais e traduzidos e nos corpora comparáveis em português e em inglês. Essa diferença apontaria que os termos não seriam unívocos dentro dessa linguagem de especialidade devido às diferenças de uso pelos especialistas de cardiologia para designar um mesmo referente.

This paper presents a proposal for the semantic treatment of ambiguous homographic forms in Brazilian Portuguese, and to offer linguistic strategies for its computational implementation in Systems of Natural Language Processing (SNLP). Pustejovsky's Generative Lexicon was used as a theoretical model. From this model, the Qualia Structure - QS (and the Formal, Telic, Agentive and Constitutive roles) was selected as one of the linguistic and semantic expedients for the achievement of disambiguation of homonym forms. So that analyzed and treated data could be manipulated, we elaborated a Lexical Knowledge Base (LKB) where lexical items are correlated and interconnected by different kinds of semantic relations in the QS and ontological information.

S. aureofaciens growth in a chemically defined medium was associated with the active secretion of nucleic acid-related substances in the medium. High secretion depended on low availability of phosphate, and fractionation showed 7 anionic substances were secreted as major components. When compared to 76 known purine and pyrimidine derivatives only erotic acid was identified. Cationic components are among the minor concentration components secreted which have been identified as cytosine, inosine, cytidine, adenine, guanine and, probably, 1-methyl-adenine.

This paper is a qualitative ethnographic study that aims to present reflections on negotiation events in teletandem interactions, a synchronous telecollaborative context of language learning, within the scope of the interaction strategies adopted by participants to achieve comprehensibility. The project Teletandem Brasil: foreign languages for all (Telles, 2006) matches up native or proficient speakers of a foreign language with Brazilian undergraduate students to learn each other's language, by communicating synchronically with application softwares like Skype, Oovoo or MSN. on this paper, based on the interpretive perspective of Hermeneutics, we analyze excerpts of teletandem interactions of partnerships established between students of a Brazilian university and American universities. The excerpts presented here have been taken from different moments of the research studies conducted at the teletandem laboratories of UNESP Assis and Sao Jose do Rio Preto and are part of the database of the works of Santos (2008) and Garcia (2010). In this article, in the data analysis, we highlight the focus on form and on lexicon as characteristics of the interactions and analyze how the negotiations happen in this learning context mediated by technology. Among results we may highlight the prevailing of external feedback as a trigger to negotiation moves, the occurrence of adjustment processes between participants to get adapted to each other's interaction behavior, as well as the evolution of this behavior as interactants get familiarized with the computer-mediated communication context, under the shape of changes in the participants choices regarding negotiation of meaning along their interaction experience.

Due to factors such as globalization and the demography of Hispanic countries, the Spanish language has influenced worldwide, especially since the last decade of the 20th century, mainly countries which are geographically close to Spanish American countries, such as Brazil. In this context, it is necessary to think of the linguistic variation of the Spanish language, in which we emphasize the lexical variation. As any language, Spanish has a colossal and wealthy lexicon with different varieties related to the characteristics from each region: history, culture, customs etc. This diversity influences the development, the amplification and the renewal of a language, as well as the teaching-learning process. Thus, we proposed to analyze the lexicon varieties of Spanish language entries in some Spanish-Portuguese bilingual dictionaries for Brazilian learners. In order to achieve this goal, we selected some examples of lexical variety in a corpus organized with texts of different textual genres and we verified if these lexical items are registered in the dictionaries chosen. As the corpus is organized from texts present in didactic manuals used in Brazil, our goal is to verify if the vocabulary which the Brazilian learner has contact in formal education is registered in the analyzed dictionaries.

Besides a philosophical glossary, Kant handles many other linguistic repertoires; among them, for instance, the musical ones. The present study, by considering the kantian musical lexicon, is not intended to promote the music in the realm of critical philosophy from a aesthetic point of view, but to recognize and to examine in a preliminary manner an argumentative resource used by the philosopher, namely, the musical analogy.
