Managing Scholarly Communication in the Web 2.0 Environment: The Role of University Libraries

Scholarly communication over the past 10 to 15 years has gained a tremendous momentum with the advent of Internet and the World Wide Web. The web has transformed the ways by which people search, find, use and communicate information. Innovations in web technology since 2005 have brought out an array of new services and facilities and an enhanced version of the web named Web 2.0. Web 2.0 facilitates a collaborative environment in which the information users can interact with the information. Web 2.0 enables its users to create, annotate, review, share re-use and represent the information in new ways thereby optimizing the information dissemination

physics of the Web

Science is search for the laws of underlying phenomena of the nature. Engineering constructs the nature as we wish. Interestingly the huge engineering infrastructure like world wide web has grown in such a complex structure such that we need to see the fundamental science behind the structure and behaviour of these networks. This talk covers the science behind the complex networks like web, biological, social etc. The talk aim to discuss the basic theories that govern the static as well as the dynamics of such interesting networks

Small World Folksonomies: Clustering in Tri-Partite Hypergraphs

Many recent Web 2.0 resource sharing applications can be subsumed under the "folksonomy" moniker. Regardless of the type of resource shared, all of these share a common structure describing the assignment of tags to resources by users. In this report, we generalize the notions of clustering and characteristic path length which play a major role in the current research on networks, where they are used to describe the small-world effects on many observable network datasets. To that end, we show that the notion of clustering has two facets which are not equivalent in the generalized setting. The new measures are evaluated on two large-scale folksonomy datasets from resource sharing systems on the web.

Disseny i implementació d'un sistema web de geolocalització i promoció d'events

Degut a la falta d'informació, de temps, no saber a on buscar. . . moltes vegades no ens assabentem, o ho fem massa tard, d'events als que ens hauria agradat assistir, com podrien ser concerts,conferències, activitats esportives, etc. L'objectiu d'aquest projecte serà aprofitar les capacitats de les xarxes socials per crear un lloc web que permeti enviar i geolocalitzar events que podran ser revisats i promoguts pels usuaris, de forma que es pugui suplir aquesta mancança. La solució implementada haurà de proporcionar les següents funcionalitats: enviament d'events (permetrà afegir les dades principals d'un event i geolocalitzar-lo en el mapa); organització de la informació (es disposarà de categories i metacategories per agrupar els events, a més d'un sistema d'etiquetes que facilitarà les cerques en el contingut del web); exploració dels events existents (mitjançant el mapa es podrà veure les dades de qualsevol event); sistema de votació (atorgarà la capacitat per poder decidir quina informació és més rellevant); agenda personal (servirà per registrar events i d'aquesta manera poder rebre notificacions que informin de canvis o simplement que serveixin com a recordatori); comunicació entre usuaris (es realitzarà a través de comentaris al peu dels events i/o d'un xat intern); sindicació web (distribuirà el contingut utilitzant l'estàndard RSS; disponibilitat d'una API simple (permetrà l'accés a certa informació des d'aplicacions externes)

Adaptive intelligent agent approach to guide the web navigation on the PLAN-G distance learning platform

Hypermedia systems based on the Web for open distance education are becoming increasingly popular as tools for user-driven access learning information. Adaptive hypermedia is a new direction in research within the area of user-adaptive systems, to increase its functionality by making it personalized [Eklu 961. This paper sketches a general agents architecture to include navigational adaptability and user-friendly processes which would guide and accompany the student during hislher learning on the PLAN-G hypermedia system (New Generation Telematics Platform to Support Open and Distance Learning), with the aid of computer networks and specifically WWW technology [Marz 98-1] [Marz 98-2]. The PLAN-G actual prototype is successfully used with some informatics courses (the current version has no agents yet). The propased multi-agent system, contains two different types of adaptive autonomous software agents: Personal Digital Agents {Interface), to interacl directly with the student when necessary; and Information Agents (Intermediaries), to filtrate and discover information to learn and to adapt navigation space to a specific student

A visibilidade das universidades portuguesas na web : estudo webométrico

Esta dissertação resulta de uma investigação que levou a cabo um estudo webométrico sobre a presença das universidades portuguesas na Web, avaliando a visibilidade das instituições através do cálculo de um indicador webométrico, o Web Impact Factor. A World Wide Web é, na atualidade, um dos principais meios de difusão de Informação. Os Estudos Métricos da Informação visam quantificar e avaliar a produção de Informação, objeto de estudo de disciplinas como a Infometria, a Cienciometria e a Bibliometria. Recentemente, surgiram a Cibermetria e a Webometria como novas disciplinas que estudam a produção e difusão da Informação no contexto do Ciberespaço e da World Wide Web, respetivamente. As universidades, enquanto polos privilegiados de produção e difusão de conhecimento, são o objeto de estudo natural da Webometria e a avaliação da sua presença na World Wide Web contribui para a análise do desempenho destas instituições. Para a realização deste trabalho foi adotada a metodologia proposta por Noruzi, que calcula três categorias de Web Impact Factor: o WIF Total, o WIF Revisto e o Selflink WIF. De modo a calcular estas categorias, foram recolhidos dados quantitativos de inlinks, selflinks, número total de páginas e número de páginas indexadas pelo motor de pesquisa. O motor de pesquisa utilizado foi o Altavista, tendo sido realizadas pesquisas de expressões booleanas durante o primeiro semestre de 2009. Após a recolha, os dados foram tratados estatisticamente e procedeu-se ao cálculo das categorias do WIF. Conclui-se que existe uma maior visibilidade das universidades públicas portuguesas porque obtêm melhores resultados ao nível de duas categorias do Web Impact Factor: o WIF Revisto e o Selflink WIF.
