As duas primeiras seções deste artigo tratam de nomes que ocupam a segunda posição em grupos N1 N2 do português do Brasil. Investigamos um corpus de 224 ocorrências extraídas de amostras de literatura romanesca, jornalística, dramática, técnica e oratória. O objetivo era uma proposta de tratamento lexicográfico para tais nomes num dicionário de usos do português. Tentamos responder a questões sobre a classificação e as funções de N2, com base nas seguintes características: função qualificadora; possibilidade de gradação; coordenação com adjetivos; ausência de função temática; concordância. Utilizando essas propriedades, estabelecemos uma hierarquia para a classificação de N2: os que exibem a maior parte das propriedades acima seriam classificados como adjetivos; os demais mantêm o estatuto de substantivo. Na terceira seção discutimos a análise de 372 nomes do inglês (extraídos de jornais e revistas), de acordo com os mesmos critérios, e concluímos que, embora a maioria dos substantivos adnominais do inglês não possa ser classificada como adjetivo, alguns substantivos qualificadores sofrem a conversão. Os adjetivos não predicativos, porém, nunca mudam de categoria. A comparação entre o inglês e o português, na seção 4, mostra que o comportamento dos nomes não predicativos difere quantitativamente, mas não qualitativamente, nas duas línguas.

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.

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.

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.
