MathDoc and the Electronic Publishing of Mathematics
No full textFrance has a long tradition in the publication of mathematics. The very first ?mathematics only? journal in the world, the Annales de Gergonne was published from 1810 to 1831 and several of the foremost current mathematical journals are published in France today. This paper will develop the original work of the ?MathDoc? team to make accessible these and other journals, and more generally to promote the electronic publishing of mathematics.MathDoc is a small multidisciplinary team, supported by Universit? Joseph Fourier Grenoble and CNRS , whose competences range through mathematics, computer science, databases and Information Retrieval to documentation and librarianship.MathDoc is devoted to providing access to mathematical literature in the broad sense.Examples will be given of different applications and projects in the field of electronic publishing and digital libraries.? The NUMDAM archive giving access to over 8000 retro digitised articles:We shall present the editorial and technical choices of the archive, and develop some of its more interesting features such as its hyperlink network.? Front Math for Gallica:The French National Library (BnF) has a great many digitised math documents, in particular the complete works of many remarkable mathematicians. These can be found on BnF?s digital library website. However, the granularity of the BnF metadata is not sufficient to easily find individual papers. The Gallica front-end will be presented.? The ? p?le des revues de math?matiques ?, mathematical journals portal, started in 2005: The aim of this project is to provide a complete electronic publishing infrastructure to several academically published French (and European) mathematical journals, and manage their websites. The main workflow functionalities will be described, and focus will be made on the originality of mathematics publishing as opposed to publishing other sciences.? Seamless web access to digital or digitised math documents (mini-DML):We will describe the aims of the mini-DML project, the required infrastructure, and the technology for providing a one-stop search site for all digital mathematical literature available online
The need for sharing user-profiles in digital libraries
No full textPersonalization was a hype in the late 1990s. Several organizations offered (and are still offering) personalization services for their customers. From e-commerce applications we know that people are willing to provide their names and other personal data if they know exactly how this information is used. Many of us are using different Digital Libraries on a regular basis. If our interests change, we have to update all profiles stored at these different server systems. This task is time consuming and error prone. Since there is no single Digital Library which covers all information-resources a user needs, there is a need to exchange personal data (especially personal interests). In this article we will show that user-profiles are important to satisfy users? needs, which information about users should be stored in profiles. Just parts of the profile must be shared with other service providers. It will be shown, that it is not possible to predict usage of properties. Therefore the user itself must decide which properties may be shared with others and which properties should not be accessible by certain services
Ontology extraction for index generation
No full textThe administration of electronic publication in the Information Era congregates old and new problems, especially those related with Information Retrieval and Automatic Knowledge Extraction. This article presents an Information Retrieval System that uses Natural Language Processing and Ontology to index collection?s texts. We describe a system that constructs a domain specific ontology, starting from the syntactic and semantic analyses of the texts that compose the collection. First the texts are tokenized, then a robust syntactic analysis is made, subsequently the semantic analysis is accomplished in conformity with a metalanguage of knowledge representation, based on a basic ontology composed of 47 classes. The ontology, automatically extracted, generates richer domain specific knowledge. It propitiates, through its semantic net, the right conditions for the user to find with larger efficiency and agility the terms adapted for the consultation to the texts. A prototype of this system was built and used for the indexation of a collection of 221 electronic texts of Information Science written in Portuguese from Brazil. Instead of being based in statistical theories, we propose a robust Information Retrieval System that uses cognitive theories, allowing a larger efficiency in the answer to the users? queries
Evaluation of emerging e-journals in science and technology: a proposed methodology based on analysis of links to e-journals sites
No full textThis paper reports the results of a research project, sponsored by CNPq ? the Brazilian Council for the Development of Science an Technology -, which develops an evaluation methodology for the emerging Brazilian ejournals in science and thecnology. In Information Science, citation is a traditional measure of prestige for a scientific journal. Brazilian ejournals are a recent reality in Brazilian Web scenario. One of the main barriers to increase their use by the Brazilian academic community is the lack of systematic evaluation, like that provided by ISI?s impact factor. The proposed methodology were based on the quantitative and qualitative analysis of the links to the site of the ejournal, obtained by submitting its URL to Google search engine. The methodology considers not only the number of links directed to a site, but also the existence of qualitative links, those of ?authorities? sites in an specific knowledge area, and those of non-Brazilian institutions. ?Authorities?, in Brazilian scientific scenario, are considered sites of institutions like specialized or academic libraries, sites of scientific or professional associations and sites of important post-graduate programs in a specific area. NonBrazilian sites were also considered qualitative links, because they indicate the achievement of an ejournal. These different kinds of links were weighted and used to calculate a grade to an ejournal site, as an indicator of its relevance in a knowledge area. The methodology was first tested and fine tuned in Information Science area and then applied to Brazilian ejournals of several knowledge areas.. This paper reports the results and discusses future developments such as how the methodology could be automated and made available through a web site, having as input URLs of e-journal sites and URLs of community agreed ?authorities? sites in a given area. This proposal, in the scope of Brazilian public policies concerning scientific and technological information, could constitute a cooperative evaluation web resource to the Brazilian scientific community, in addition to other resources like the SciELO gateway (http://www.scielo.br) and the CAPES scientific journals gateway (http://www.periodicos.capes.gov.br)
Electronic publishing for academics: geology and physics in Russian network for natural sciences
No full textElectronic publications have proven to be crucial for supplying the scientific community with up-todate research results and instruments for both education and research. Present work summarizes the experience of development and maintenance of two natural science oriented servers and their integration with related databases and web-resources. The Russian network for natural sciences pursues the aim of providing the scientific society of the CIS states with high quality tools for peerreviewed scientific publishing in Russian and other languages with full public availability and an open archive of handbooks and textbooks on geology and physics. Web-based software for scientific calculations, forums, various information services and an ample catalogue of related scientific resources combined with search and classification tools are also presented on the Network. Search forms for geology and physics resources freely distributed among interested third-party sites and means of mutual information exchange based on XML serve the aim of deep integration of scientific resources. Designed and launched with the support of Moscow State University in 1997 and 2000 respectively, the Geo.Web.Ru and Phys.Web.Ru servers provide users with thousands of scientific and popular books, articles and sketches on physics (over 2,200 documents) and geology (over 4,700 documents). The servers are by now among the top-ranked resources for Russian-speaking scientific auditorium according to usage statistics
State-of-the-art of Brazilian e-journals in science and technology
No full textThis paper reports partial results of a research project, sponsored by CNPq ? the Brazilian Council for the Development of Science and Technology -, grant number 550693/2002-5, for the period of 2003/2006. It aims to develop a comprehensive framework of the Brazilian electronic journals in Science and Technology situation. With the facilities for web publishing electronic journals, the first difficulty faced by the research was to identify the majority of the Brazilian ejournals in Science and Technology, due to the lack of a centralized bibliographic control information resource. An extensive research on the Web had to be done in order to map Web sites of ejournals. Besides the use of bibliographic control devices like the SciELO portal (http://www.scielo.br), which holds a collection of more than 100 ejournals, and LatinIndex portal (http://www.latindex.org), with more than 300 ejournals - including those held by SciELO -, Google and AltaVista search engines were used to identify the sites of Brazilian ejournals.. Queries were submitted to those search engines like ?Brazilian Journal of?, ?Brazilian Archives of? etc, to identify additional ejournal sites. In each site, information about each ejournal was gathered, and stored in a database, according to its knowledge field, the kind editor, publication currency, technological aspects such as electronic text formats used, availability of a site search engine, if the ejournal belongs to a portal. The universe of Brazilian ejournal seems segmented. It varies from high quality and consolidated ejournals ? which are originated from printed journals and are published by high-tech portals like SciELO ?, to emerging ones ? without printed version, recently set up ejournals-, produced by research groups which could take the benefits of the facilities of publishing in an university or research institute web servers; this universe also encompass different knowledge fields, with predominance of ejournals in health and biological sciences. After this initial phase, a qualitative research had to be carried out, based in questionnaires sent to the ejournals editors by email. Questionnaires were sent to each specific segment of the Brazilian ejournals universe. Questionnaires asked for information relative to ejournal business model, difficulties to maintain the currency of the ejournal, existence of long term preservation policies, use of metadata standards, troubles faced at the set up of an ejournal. All this information is being compared with the Brazilian public policies relative to information in Science and Technology
Technical advances in scientific and scholarly publication
No full textThe accepted role of scientific and scholarly publication is to record research activity in a timely fashion, keeping others in the research community up-to-date with current developments. Until very recently, it has been the case that printed journals were the most efficient method for the dissemination and archival of research results. Technical advances in the past decade have allowed the process of scholarly communication to take other forms, particularly in the dissemination and storage of articles via the World Wide Web. Developed at CERN to facilitate ?instantaneous information sharing between physicists working in different universities and institutes all over the world? it gave publishers a new medium for making their journal archives available (Hitchcock et al. 1996). It also gave authors the means to break the so-called ?Faustian bargain? and directly distribute their articles in pre- or post-publication form from their own Web pages (Harnad 1995) or in organised ?eprint archives? (Ginsparg 1996). It was not only the technical advance provided by the printing press in the late 15th century but the emergence of a reliable postal system and the development of the experimental method in the 16th century that led to the production of the first Scientific Journal in 1665 (Schaffner 1994). In the 21st Century, it may not be simply the technical ability to reproduce and distribute articles electronically (epublishing), but also the pressure to develop collaborative, large-scale investigations and analyses (e-science) that leads to significant change in the field of scientific communication and significant changes in the way such communications are produced, curated and disseminated (Lucier 1990)
