V-CHAT - Versatile Chat
No full textWe focus our research on text based messaging systems and the impact they have when they are implemented in a work structure and how this kind of software can improve workflow and interaction between firms and clients both in B2B and B2C relations. In recent years many online text chat systems have been developed and use. Internet Relay Chat or IRC, ICQ, AOL and MSN are some examples of the most popular tools for real-time communications via the Internet and have been used both for doing serious work, decision making and for entertainment purpose. Messaging programs tend to imitate each other and they imitate other chat programs either. Each new release simply adds new features that keep the use of this software nothing but a cheaper alternative to phone. Nowadays Instant Messaging, chat system and video conference software must evolve and specialize into something more flexible, sophisticated and secure
Electro-shock for the congress paper. P-Web: an online publishing tool for conference proceedings
No full textIn many scientific disciplines proceedings of conferences are essential for scientists and scholars to keep informed about the results of current research. Online accessible conference proceedings are gradually replacing the traditional paper-based proceedings. This paper presents the principles and functioning of P-Web, an online publishing tool for conference proceedings, which aims at supporting the quality of scholarly communication and the scientific process in general. In the context of an ever increasing emphasis on online scientific publishing, P-web can help conference organizers and presenters by making their work available for a wider audience. P-Web can optimize and enhance the findability and reuse of online conference proceedings. P-Web catalogues the conference papers that can be found in the different institutional repositories of the participating authors. P-Web harvests the metadata records from the institutional repositories according to the OAI protocol. Since in this protocol only a minimal metadata set is assumed, enrichment of this set with additional metadata is indispensable. Basic conference details need to be entered by the conference organizers who want their online proceedings to be exposed via P-Web. By enrichment of the harvested metadata set, PWeb is an interface between data providers like institutional repositories and subject-oriented repositories on the one hand and for example awareness services like ISI?s Current Web contents and INFORMS Online on the other. P-Web is both a service provider and an intermediate data provider. It has been developed as an open source product by the Erasmus University Rotterdam and the University of Twente, The Netherlands, within the Digital Academic Repository program (DARE)
Experiences with web-based scientific collaboration: managing the submission and review process of scientific conferences
No full textThis paper discusses the logistics of the submission and review process of conference entries by means of a ?free?, web-based application. In the framework of the SciX-project - an acronym for ?Open, self organising repository for scientific information exchange?, SOPS (?SciX Open Publishing Services?) has been developed. The SciX-project framework has already been elaborated in the ELPUB 2002 contribution and on the occasion of ELPUB 2003 the creation of a Digital Library for ELPUB was presented. An outline of SOPS as an publishing aid for conference organizers will be worked out in this paper, using the case study ofthe IAPS 2004 conference. The SOPSconference application provides the functionality to support the organisation of a conference. It handles the registration of participants, submission and reviewing of abstracts, full-paper submission, reviewing and publishing. By means of other SOPS-services already a repository with previous conference papers has been realized for the IAPS-association
Convergence and divergence in media: different perspectives
No full textA current issue in the media industry is coping with the effects of convergence. The concept of convergence is frequently used both in the academic field and within the media industry to denote the ongoing restructuring of media companies as well as to describe the latest developments in media forms, distribution, and consumption. However, there is currently no generally accepted definition of the concept. Depending on the context, the meaning and connotations vary. Some researchers suggest that convergence is a result of a change toward a more modern media society while others treat the concept as denoting the actual process toward a more efficient management of the media value chain. This paper discusses various definitions of convergence, both in a historical perspective and as it is used and understood in contemporary media and communications research, one aim being the evaluation of how the meaning of the concept has evolved during the past decade. The study is based on literature research and one conclusion is that convergence is a process dependent on current circumstances within society. The use of the concept has therefore developed from being mainly connected with digitalization in media technology to also include elements of integration, combination, competition and divergence. This paper suggests that convergence should be seen as an ongoing process of media and media industry development that is dependent on and in continuous interplay with a contrasting and complementary process, that of media divergence
RDF Applications in Digital Library
No full textDespite the dissemination of user-friendly search engines which allow for the retrieval of scientific information in computer networks, researchers do not always obtain expected results in a simple and efficient manner. There is increasingly evidence that the scientific community, in particular Social and Humanities researchers, finds it difficult to accurately retrieve their information requirements through the Web. Some of the difficulties are magnified by the fact that the Web organization is not based on commonly adopted standards. Therefore one needs to gather, organize and better disseminate the freely available scientific information on the Web through the use of open standards in digital libraries. Resource Description Framework (RDF) is one important standard from the World Wide Web Consortium (W3C). In our talk we introduce some of the standards aiming to better understand how digital library could benefits from them
What academic libraries need from e-publishers
No full textWhile electronic publications can greatly increase a university community?s access to information, they also pose many challenges to the libraries charged with collecting and managing them. In the print environment, libraries purchase and own content in perpetuity, while in the electronic environment, they generally lease access to content for limited time periods on a subscription basis. This paradigm shift, often referred to as the ?ownership vs. access? model, has profound consequences. The leasing of information is frequently governed by a license agreement entered into by the library and a publisher or vendor. As license agreements are contracts, and, in the United States contract law supersedes existing law such as U.S. Copyright Law, license agreements have the power to undo a user community?s rights to use information in ways long assumed in the print environment. Publishers and libraries must work together to negotiate agreements that benefit both. Beyond the development of fair license agreements, e-publishers wanting to market to academic libraries should design their products in ways that allow them to be easily integrated into a libraries greater e-collection and infrastructure. Today, many libraries are implementing products that integrate their individual esubscriptions, allowing interlinking of abstracting and indexing databases with full-text sources, and providing the ability to search across multiple databases simultaneously. Publishers must also work collaboratively with libraries to address the issue of archiving in the electronic environment. The libraries role to continue to collect and preserve the history of our society is uncertain in the digital world, where most libraries are as yet unprepared and unequipped to systematically handle large volumes of electronic content. Even where they are able to do so, the contracts governing use of electronically published materials frequently forbid libraries from duplicating their content for archival purposes. For usability, e-publications need to be designed with levels of granularity that provide the ability to link directly to the article level in journals is essential. Article level linking is necessary for libraries to effectively integrate various systems via link-resolvers and course management software. Both publishers and libraries need to be able to collect information about the use of their e-content, so the development of standards for usage statistics must be achieved. In order to manage their e-collections, libraries need to be able to collect usage statistics, just as they collect and analyze circulation statistics for their print collections. A new international Code of Practice, developed by COUNTER, is gaining wide international support by librarians and e-publishers, as well as they professional organizations, and libraries are increasingly asking their e-publishers to be COUNTER compliant
Towards a new authoring environment: overview of some ontology based systems
No full textThis paper presents some requirements for a new ontology-based authoring environment. By analyzing some systems that use ontologies for several tasks, we identified some features and purposes and showed how they can contribute to help define a new authoring environment based on ontologies to represent information before a document is published. The systems analysed fulfil specific tasks such as semantic annotation, visualization, document review and argumentation, information extraction and text engineering. By identifying some key features, it was clear that none of the tools could deliver the solution as a whole, but the integration of similar purpose tools into an interoperable environment can be a great contribution to ontology-based authoring environments. Even though Semantic Web technologies have revealed a trend in the use of ontologies for information processing, yet substantial work needs to be done to gather these initiatives in order to build an interoperable new authoring environment that takes advantage of present and new technologies
DSpace-dev at University of Minho
No full textThe University of Minho (UMinho) was the first institution in the Portuguese speaking world to use a translated version of Dspace. DSpace related activities at University of Minho started in April 2003 and since then many developments have been made. The first step has been taken by the UMinho Documentation Services (SDUM) with the translation of the DSpace system to Portuguese and its implementation in the Reposit?riUM (http:/ /repositorium.sdum.uminho.pt), the institutional repository of UMinho, created to store, preserve and disseminate the intellectual output of the University. This version has been downloaded for use in many other institutions in Portugal and Brazil. This same version was used as a basis for the papadocs system (http://papadocs. dsi.uminho.pt ). Papadocs intends to store and provide access to all assignments made by the Information Systems? department alumni. Some changes had to be made to the original version, in particular in what concerns the metadata. Other changes and plug-ins have been developed in order to better conform to our needs. These include the restriction of values for keywords accordingly to the ACM Computing Classification System and the Keyword Classification Scheme for IS Research Literature (developed and available both in XML and in RDF-S) and the development and implementation of a commenting module together with a 3D visualization of what we call the ?Web of Communication?. Two other instances are planned to be installed in the near future: one for storing all the articles from a well-known journal in the Information Systems area (this can later be open to other journals); and another to store cultural heritage documents related to the history of computing in the country (waiting for funding from the local funding body ? FCT). In this talk I will present these four initiatives and discuss the related research projects currently in hands
Putting Local Knowledge Online: does it become international?
No full textAccess to scientific information and knowledge in the framework of the Internet has steadily grown in recent years, with special advantages for the information generated in developed countries. In other parts of the world a number of factors are influencing the capacity to generate and use scientific information online, i.a. connectivity problems, lack of financial resources, weak institutional support and infrastructure, and poor training in the electronic publishing and dissemination tools. Latin America (including the Caribbean) has been relatively slow in adopting the Internet: our users represent today 3.6% of the world?s total, against 36.9% from North America, 30% from Europe and 27% from Asia and the Pacific. The Internet infrastructure shows even lower figures: only 1.6% of the world?s total corresponds to Latin America, with 2.4% of the domains. As a result, only 3% of webpages offer contents in Spanish and 1% in Portuguese, against 75% in English. Against this background, it should be noted that also in Latin America, universities and higher education institutions, as well as national research councils, are active promoters of the web as an ideal means to put local information and knowledge online. Is this purpose being successfully achieved? In partial answer to this question; the present paper refers to a specific experience that has developed on the basis of regional cooperation among national institutions involved in scientific publishing
Introduction
No full textIt is significant that the Elpub meeting this year is held in Brazil, as we need to acknowledge that while the use of Information and Communication Technology (ICT) is now truly global, its development and diffusion is still highly uneven around the world. This Special Session brings together researchers and practitioners from various regions of the Americas who have extensive experience using ICT for various aspects of development and scientific advancement. The key objectives is to share practical strategies for knowledge and community building using appropriate technology, and to exchange lessons on bridging ?expert? and ?lay? knowledge in the local as well as the global context
