Presents a developing laboratory within History of Culture, subject taught in the Library and Archive Studies at UNESP (Marilia). The project is based upon the foundations of research line Information and Technology: students from the second under graduation year participate in the improving of 27 entries in Portuguese language Wikipedia. The aim is to capacitate for scientific reading and writing in digital media, habilitate for the information identification and recuperation and for the interpretation and understanding of formal and contents aspects and its reorganization. It includes activities of search, selection, remix and republishing of texts, images, audio and videos in the convergence of diverse hypertext information sources, supported by tutors with strategic abilities in digital environments. In this sense it was adhered to the international Wikipedia Foundation University Campus Ambassadors project. It’s also aimed to induce sharing and collaboration behaviors with the purpose of creating necessary habits for the informational empowerment in Brazil. As methodology is to optimize the work of individuals already trained in wiki culture and to create in within the subject information sharing programs with a more specialized bias, giving greater credibility to the digital environment. The environment syntaxes helps in the learning of the complementary skills of reading and writing and offers itself as an open repository from which information can be reused. It is, thus, an empowerment strategy in the search of autonomy and self reliance considering intersemiotic knowledge in the edition, visualization and understanding of information in the social web. A second step of a verifying research on the environment’s credibility after the consolidation and dissemination of the entries improvement work is proposed.

Information organization can be considered as a nuclear area in Information Science and its historical background has been historically built based on three theoretical approaches: subject cataloguing, under a North-American influence, Indexing, under a British influence, and document analysis, under a French influence. In this sense, although one can consider the strong influence of the logic-linguistic approach of the French tradition in information organization both in Brazil and in Spain, it is not already clear in what extent the mentioned influence specifically occurs in Brazil and Spain as well as what are the dialogical perspectives between them. So, and in order to analyze how the Information Science academic environments in Brazil and in Spain conceive the interdisciplinary relationships in the domain of document analysis (DA), it was applied a questionnaire to Brazilian and Spain DO researchers based on the records of the Brazilian and the Spanish International Society for Knowledge Organization chapters. The results (64,5% of answers in Brazil and 60,6% in Spain) allowed the identification of 35 DA interdisciplinary relationships in Brazil and 98 in Spain, whose data were so grouped in 7 matrixes ? cognitive, philosophical, historical, logic-lingusitic, quantitative, social and political, and technological. It was possible to observe that the logical-linguistic matrix is strongly predominant (90% of the answers in Brazil and in Spain) what reflects the influence of the ideas of Jean-Claude Gardin. On the other side, the graphic visualization of authors´s network showed a strong perspective of dialogical relationships among Brazilian and Spanish DA researchers, based on the convergence of theoretical conceptions, what allow us to conclude the need of joint research policies between both coountries in order to make the mention ed dialogical relationships real and fruitful.

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.

This piece of research aims at analyzing the absolute and relative co-citation indicators, especially Salton’s Cosine and comparing the contribution of these indicators to the understanding of a domain, applying them to the universe of "Metric Studies" at the BRAPCI base. It also aims at presenting the co-citation network generated from the absolute frequencies and highlighting the groupings of co-cited authors, depending on the relative values, integrating and explaining the information from the two indexes. The domain analysis, by means of its 11 approaches, including “Bibliometric Studies”, focuses on the science characterization and evaluation, in that it allows us to identify and to analyze the conditions under which the scientific knowledge is constructed and socialized. In these studies, the contribution of citation and co-citation analysis is highlighted. Of the total of 147 articles retrieved at BRAPCI base, the authors cited in at least 11 articles, in a total of 38 researchers, were selected. The 38 x 38 symmetric matrix with the absolute frequencies of co-citation and the matrix with the relative values of Salton’s Cosine were generated. The co-citation network with absolute frequency values were constructed, through Ucinet software. Cluster analysis of data with relative values wer performed, using the SPSS software. Significant differences between the absolute and relative indexes, with some high absolute values of co-citation were observed; when considered in relation to the presence of each author, their significance is decreased. As to the generated network, seven groups were determined, in which only one is established for close themes and comes from co-citations in the original sense of the term. Five groups present closeness in absolute and relative indicators. It can be concluded about the importance of the studies of authors' co-citation analysis, which associate the two indexes, absolute and relative, in order to visualize and understand the underlying structures of a scientific domain.

This article discusses the access to geographic information and its importance for the public policies formulation, reflecting on the implementation of the Spatial Data Infrastructure. The data view and the maps construction are useful for identifying needs and sponsoring public managers in decision making. The public policies implementation stages are optimized when the quantitative and qualitative information are integrated to the spatial phenomena relations. The improvement in the use of geographic information for decision making will be achieved when spatial data are efficiently generated in spatial data infrastructures.
