webometria, definindo o lugar que esta ocupa dentro da Ci?ncia da Informa??o e
o seu inter-relacionamento com os tradicionais campos das m?tricas (bibliometria,
cientometria e informetria), assim como a an?lise dos fluxos da informa??o na
Web, mediante a aplica??o de diferentes indicadores webom?tricos aos s?tios dos
centros filiados ao Conselho Latino-Americano de Ci?ncias Sociais (CLACSO). Os
indicadores webom?tricos utilizados s?o: Tamanho do S?tio, Visibilidade,
Luminosidade, Fator de Impacto Web, Densidade por Link e Densidade da Rede.
O foco de an?lise ? o estudo dos links enquanto fontes de informa??o e como
instrumentos de conex?o que influenciam e s?o influenciados pelos v?nculos
acad?micos neste ambiente. Para a extra??o, quantifica??o e representa??o
gr?fica dos dados s?o utilizados motores de busca (Google, Yahoo e Alta Vista),
programas mapeadores (Xenu Link Steuth) e programas de an?lise e visualiza??o
de redes (Ucinet 5 e Netdraw). Os resultados obtidos indicam que a informetria
deve ser entendida como o campo maior que compreende n?o s? a bibliometria e
a cientometria, mas tamb?m campos emergentes como a cibermetria e a
webometria. Apresenta-se a posi??o de que a webometria n?o est? totalmente
absorvida pela bibliometria, j? que a informa??o no meio digital n?o pode ser
considerada como informa??o ?registrada? e sim como ?dispon?vel? em meio
eletr?nico, havendo a necessidade de uma maior reflex?o te?rica para abrigar
novos conceitos que surgem com a influ?ncia das inova??es tecnol?gicas no
pensar e no fazer da Ci?ncia da Informa??o. A aplica??o dos indicadores
webom?tricos demonstra que o Fator de Impacto da Web e Densidade por Link
n?o oferecem resultados satisfat?rios. J? os demais indicadores demonstram sua
utilidade e relev?ncia na mensura??o dos dados coletados na Web e nos
processos de identifica??o e an?lise dos padr?es do fluxo da informa??o e inter-
relacionamento entre institui??es acad?micas dentro do mundo virtual. O estudo
demonstra tamb?m que a maioria dos s?tios latino-americanos de ci?ncias sociais
estabelece poucas rela??es com outros centros do mesmo pa?s e de outros paises
da regi?o na Web, o que se traduz em uma densidade de rede em geral bastante
baixa e deixa em evid?ncia o importante potencial de conectividade a ser
explorado no futuro pelo CLACSO e pelos seus centros membros. ABSTRACT: The main propose of this study is to research the field of webometrics, and define its role within Information Science and its relation with traditional metric fields (bibliometrics, scientometrics and informetrics). Also, by applying different webometric indicators to the sites of centers affiliated to the Latin American Council of Social Sciences (CLACSO), this study analyzes the information flows that occur inside the Web. The webometric indicators utilized are: Site Size, Visibility, Luminosity, Web Impact Factor, Link Density and Network Density. The analysis focuses mainly on an examination of links. These are regarded as sources of information and as instruments of connection that influence scholarly relationships within this virtual environment, at the same time being influenced by those relationships. Search engines such as Google, Yahoo and Alta Vista, link checking software such as Xenu Link Steuth, and programs for analysis and visualization of large networks such as Ucinet 5 and Netdraw are utilized for data collection, quantification and graphic representation of data. The results obtained indicate that infometrics has to be understood as a large field to include not only bibliometrics and scientometrics, but also emergent fields such as cybermetrics
and webometrics. According to this research, webometrics should not be completely absorbed by bibliometrics, because the information in this digital environment cannot be considered as ?recorded.? Instead, this information should be seen as ?available? in electronic support. Therefore, it is necessary to think
about a broader theoretical framework that allows us to include the new concepts
that come out with the influence of technological innovations on the thinking and
the makings of Information Science. The application of webometric indicators
demonstrates that Link Density and the Web Impact Factor are insufficient. On the
other hand, the other indicators stand out as useful, and are relevant tools to the
measurement of data collected in the Web, as well as to the processes of
information flows and to the interrelation among scholarly institutions inside the
virtual world. This study also demonstrates that most of Latin American social
sciences websites establish very few connections with the websites of other
centers of the same country or region, which is reflected on a relatively low
Network Density and emphasizes the enormous potential of connectivity as an
area to be developed in the future by CLACSO and its member centers
