Abstract

This study analyzes the models of representation and organization of knowledge surrounding Gender. In addition to assessing their visibility, we analyze the thematic models and the conceptual treatment of Gender in search engine directories with wide coverage in different parts of the world. Eight seach engines were selected, two of them international (Yahoo, Google), one an international affiliate (Yahoo España), and five local ones (three from the Mercosur, and one apiece from Africa and Asia). The research was done an two levels: a) knowledge representation through the quantitative and qualitative analysis of the terms of Gender; b) knowledge organization, through the structural and semantic-conceptual analysis of the search engines. The results express a clear terminological and structural supremacy of the international search engines, as well a lack of correspondence overall among the terminologies, relative visibility, and diffusion of matters of Gender, leading to considerable difficulties in achieving consistent access to specific information.

Abstract

The analysis of the terminological representation of interdisciplinary domains is a method that helps us identify terminological dynamics and the conceptual model to organize these spaces. This study applies this approach to Gender Studies, to arrive at the behaviour and the problems posed by the domain, and a possible model for its organization.

Abstract

Interdisciplinary subject areas such as gender studies present difficulties for their representation and structuring in indexing and information retrieval systems. This study looks into this domain based on four specialized thesauri in gender. The results point to a lack of uniformity in the terminology selected, and a high degree of conceptual dispersion of the models of the domain.

Abstract

This research studied the role of knowledge organization in the process of decision making in the field of energy efficiency and rational use of energy (EERUE). Theoretical contributions to knowledge organization and decision making are stressed. We chose to work with a type of methodology known as multiple criteria decision making-Saaty's analytical hierarchies process (AHP). This made it possible to develop a detailed analysis of the decision-making process and arrive at a hierarchical model. The model provided a structure representing the studied field, where an order of priority could be given to the decision-making process. The knowledge derived may be used in other fields of study such as information retrieval and knowledge representation.

Abstract

Knowledge changes and evolves with time. This makes it necessary for classifications and other information retrieval tools to be revised periodically to ensure that they represent an updated organization of knowledge. This problem worsens in the case of some scientific disciplines because of their degree of internal specialization and dynamism. This is the case with Biotechnology and Applied Microbiology (category taken from the Journal Citation Reports (JCR)). A way of solving this problem can be by means of an automatic classification, but also by applying multivariate techniques of analysis and neural networks. This work deals with the two last procedures. The source chosen for doing this work is the Science Citation Index (SCI-CD) database, chosen because it contains the best publications on the disciplines studied - a guarantee for them to be represented properly. We are especially concerned with the quality of the representation. All of the journals dealing with Biotechnology and Applied Microbiology in the database (152) have been selected. Each document has been represented according to the references that it includes. From this point three co-citation matrices were generated: authors, journals and articles from each document. This technique implies the use of complementary methods for document representation by the way of the three matrices processed by multivariate techniques (MDS, PCA, CA). The result is that it can be determined which classes form the intellectual structure of the disciplines studied. This would be of great help for automatic updating of bibliographic classifications and other information retrieval tools. At the same time, these techniques can work as robots for document classification, authors and publications, and allows for the generation of knowledge maps that can be used as interfaces for accessing the documents from their location in a database..
