Intelligent agents are an advanced technology utilized in Web Intelligence. When searching information from a distributed Web environment, information is retrieved by multi-agents on the client site and fused on the broker site. The current information fusion techniques rely on cooperation of agents to provide statistics. Such techniques are computationally expensive and unrealistic in the real world. In this paper, we introduce a model that uses a world ontology constructed from the Dewey Decimal Classification to acquire user profiles. By search using specific and exhaustive user profiles, information fusion techniques no longer rely on the statistics provided by agents. The model has been successfully evaluated using the large INEX data set simulating the distributed Web environment.

A pesquisa procura identificar e analisar as circunstâncias e motivações teóricas que levaram ao surgimento, no final do século XIX, da área de estudo denominada Documentação. Apresenta informações biográficas sobre os principais artífices deste projeto, os advogados e bibliógrafos belgas, Paul Otlet e Henri La Fontaine, que visaram ampliar a compreensão sobre o meio social e cultural em que atuaram. Procura ampliar a discussão sobre os fatores que motivaram em 1895 a proposta de organização racional de toda a produção intelectual do homem. Apresenta em linhas gerais a visão abrangente e integradora da Documentação que eliminando barreiras físicas, acessava acervos arquivísticos, bibliográficos e museológicos para o registro integral dos assuntos pesquisados. Discute a utilização da Classificação Decimal de Dewey (CDD) na criação do Repertório Bibliográfico Universal e analisa o processo que levou ao surgimento da Classificação Decimal Universal (CDU). Conclui sugerindo a inclusão desta visão extensiva e integradora da documentação ao referencial teórico da Ciência da Informação. Sugere que o resgate deste aporte teórico poderá contribuir para um melhor enfrentamento dos problemas da gestão do conhecimento registrado, produzido e acumulado até os dias atuais, nos mais diversos formatos, suportes e repositórios.

The following paper deals with an automatic text classification method which does not require training documents. For this method the German Subject Heading Authority File (SWD), provided by the linked data service of the German National Library is used. Recently the SWD was enriched with notations of the Dewey Decimal Classification (DDC). In consequence it became possible to utilize the subject headings as textual representations for the notations of the DDC. Basically, we we derive the classification of a text from the classification of the words in the text given by the thesaurus. The method was tested by classifying 3826 OAI-Records from 7 different repositories. Mean reciprocal rank and recall were chosen as evaluation measure. Direct comparison to a machine learning method has shown that this method is definitely competitive. Thus we can conclude that the enriched version of the SWD provides high quality information with a broad coverage for classification of German scientific articles.

This study explores, in 3 steps, how the 3 main library classification systems, the Library of Congress Classification, the Dewey Decimal Classification, and the Universal Decimal Classification, cover human knowledge. First, we mapped the knowledge covered by the 3 systems. We used the 10 Pillars of Knowledge: Map of Human Knowledge, which comprises 10 pillars, as an evaluative model. We mapped all the subject-based classes and subclasses that are part of the first 2 levels of the 3 hierarchical structures. Then, we zoomed into each of the 10 pillars and analyzed how the three systems cover the 10 knowledge domains. Finally, we focused on the 3 library systems. Based on the way each one of them covers the 10 knowledge domains, it is evident that they failed to adequately and systematically present contemporary human knowledge. They are unsystematic and biased, and, at the top 2 levels of the hierarchical structures, they are incomplete.

We analysed the written statements of libraries that have adopted the bookstore model for coherence or lack of coherence with common public library guidelines. We used a text-based Foucauldian genealogical discourse analysis to investigate the written statements used by libraries that have adopted BISAC and other aspects of the bookstore model. Libraries adopting bookstore models such as BISAC should consider the potential consequences of adopting a commercial model for a public entity. This paper has practical implications for libraries considering adopting any aspect of the bookstore model, but especially the BISAC system, as it examines the potential benefits and drawbacks of the bookstore model popular in some libraries with respect to the purposes and goals of public libraries. BISAC application in libraries seems to be part of a trend of applying commercial practices, values and terminology in libraries, perhaps not with the purpose of replacing libraries with bookstores, but with the aim for both systems to converge into a new kind of commercial entity and context. The influence of one kind of system over the other does not seem to be totally reciprocal, since the application of library practices, values and standards in bookstores has not had the same effects and resonance as has occurred in the opposite direction.
