13. A terminologia do ecoturismo como espelho de diferentes visões: agências de turismo, ambientalistas e governo / The Ecotourism´s terminology: a comparison between the way three distinct areas see it -t ravel agencies, environmental organizations and the government
The aim of this study is to establish a comparison between the way three distinct areas related to Ecotourism - travel agencies, environmental organizations and the government - try to spread their ideas, which is reflected in the way they name their activities and the concepts they adopt concerning ecotourism. In order to achieve our goals, a comparable Por

14. Um processo para a geração de recursos lingüísticos aplicáveis em ferramentas de auxílio à escrita científica.
Within the context of academic research, English is the lingua franca for various scientific disciplines. It is also widely acknowledged that producing an acceptable academic text is anything but a simple and easy task. This is particularly more acute if the author is a novice researcher and English is not his/her first language. One possible solution to min

15. LINGUISTIC BASIS FOR IDEA-ORIENTED SEARCH / AS BASES LINGÜÍSTICAS PARA A BUSCA ORIENTADA A IDÉIA
The idea-oriented search is a new pattern for search engines whose databases are composed by text files. This pattern sets out to solve a usual problem for search engines: demanding that users foresee which words are contained in the desired document, keeping them from focusing on the information they are indeed seeking. To solve this problem, the linguistic

16. SUPPORT NOUNS: OPERATIONAL CRITERIA FOR CHARACTERIZATION / O SUBSTANTIVO-SUPORTE: CRITÉRIOS OPERACIONAIS DE CARACTERIZAÇÃO
The main goal of this work is to provide operational criteria for characterizing nouns in Noun - Adjective combinations, in which the noun occurs in an analogous way to so called light verbs or support verbs, widely studied in recent years in both Linguistics and Natural Language Processing. In the work, linguistic, lexicographic and computational studies co

17. Algoritmos OPWI e LDM-GA para sistemas de conversão texto-fala de alta qualidade empregando a tecnologia SCAUS / Algorithm OPWI and LDM-GA for high quality text-to-speech synthesis based on automatic unit selection
This Thesis presents two new algorithms for Unit Selection Based Text-to-Speech systems (USBTTS). The first algorithm is the OPWI (Optimized Prototype Waveform Interpolation), which was designed to be used as a Back-End module for USB-TTS. The second algorithm is the LDM-GA (Linguistic Data Mining Using Genetic AIgorithm), which was designed to minimize trai

18. Methods for Automatic Discourse Analysis / "Métodos para análise discursiva automática"
Researches in Linguistics and Computational Linguistics have shown that a text is more than a simple sequence of juxtaposed sentences. Every text contains a highly elaborated underlying structure that relates its content, attributing coherence to the text. This structure is called discourse structure and is the object of study in the research area known as D

19. DESCRIPTION AND FORMALIZATION OF COMPOUND WORD IN BRAZILIAN PORTUGUESE FOR AN ELECTRONIC DICTIONARY / DESCRIÇÃO E FORMALIZAÇÃO DE PALAVRAS COMPOSTAS DO PORTUGUÊS DO BRASIL PARA ELABORAÇÃO DE UM DICIONÁRIO ELETRÔNICO / DESCRIPTION ET FORMALISATION DE MOTS COMPOSÉS DU BRÉSILIEN EN VUE DE L´ÉLABORATION D´UN DICTIONNAIRE ÉLECTRONIQUE
On étudie dans ce travail les noms formés par la structure NdeN qui caractérise un nom composé par juxtaposition. On a observé 1.500 séquences de mots, pour définir les critères d`identification d`un nom composé par cette structure. Le critère general est fondé sur le concept de la non compositionalité sémantique. Les tests ont été faits à pa

20. Repensando a interface sintaxe-fonologia a partir do axioma de correspondencia linear
This dissertation deals with the syntax-phonology interface. The theoretical framework consists of two complementary theories: the Minimalist Program (Chomsky 1993, 1994, 1995; Kayne 1994) &the Theory of Prosodic Hierarchy (Selkirk 1984, 1986; Nespor &Vogel 1986; Inkelas &Zec 1990). Here I make the following claims: (i) By taking the base &the recursive step

21. Discourse modeling for conciseness and gist preservation in text generation / Modelagem de discurso para o tratamento da concisão e preservação da idéia central na geração de textos
O foco deste trabalho esta, no processo automático de condensação de uma estrutura complexa de informação e de sua estruturação, para fazê-la apropriada para a expressão textual. A tese principal é que, sem um modelo de discurso, não podemos assegurar a preservação de uma idéia central, pois o processamento do discurso envolve não só a inform

22. New trends in natural language processing: statistical natural language processing.
The field of natural language processing (NLP) has seen a dramatic shift in both research direction and methodology in the past several years. In the past, most work in computational linguistics tended to focus on purely symbolic methods. Recently, more and more work is shifting toward hybrid methods that combine new empirical corpus-based methods, including

23. Toward a medical-concept representation language. The Canon Group.
The Canon Group is an informal organization of medical informatics researchers who are working on the problem of developing a "deeper" representation formalism for use in exchanging data and developing applications. Individuals in the group represent experts in such areas as knowledge representation and computational linguistics, as well as in a variety of m
