SIMS: An Ontology-based Multi-source Knowledge Management System
No full textIn the networked society, innovation projects are carried out through collaboration among wide communities of workers which interact via internet in order to gain knowledge from their collaborators. Moreover as a huge quantity of electronic information is already available on the web, workers look for knowledge items also in web information systems. Organizational web platforms have to support, therefore, cooperation through collaborative applications that integrate both knowledge publishing and sharing. In this paper a technological platform is presented. It enables a uniform and semantic based access to information items belonging to different information systems which are connected to the platform itself through specific modules, called wrappers. SIMS (Semantic Information Management System) is based both on collecting Dublin Core Medatada, which describes information items, structured in a JSR-170 compliant repository, and on the semi-automatic description of the same items based on domain ontologies, expressed in a formal language, such as OWL (Ontology Web Language). A SIMS component, called Semantic Content Navigator, allows users to navigate and access the entire knowledge base managed within the SIMS platform, using Semantic Web technologies. This work is part of the Italian research project DISCoRSO (Distributed Information Systems for CooRdinated Service Oriented interoperability)
Toward a collaborative vocabulary management system
No full textIn the age of knowledge-based economy, the always-growing necessity of an effective means to share concepts and their representation frequently leads to the development of domain specific vocabularies. However, vocabu-laries may fail to capture the real common understanding of a community, mostly because of its low involve-ment in the development phase. The paper gives a first set of considerations about a collaborative approach to vocabulary development and outlines the main issues that such approach would imply. Finally some collabora-tion use cases are proposed for solving some integrity issues that collaboration implicitly entails
An ontology-based multi-source knowledge management system: creating and accessing knowledge items on a collaborative platform
No full textA Distributed Information system to coordinate and support business process execution in a Cluster of firms.
No full textIn these years, new business paradigms have been promoted for the digitalization of enterprise processes.
Internetworked Enterprise paradigm has allowed companies and organizations to react to the climate of uncertainty
by decentralising production and innovation. In the research project DISCoRSO, we have described an effective
approach that enables SMEs transition from traditional business to e-business. The proposed solution is based on an
organizational framework and a technological framework, in order to guarantee the support of the business strategies
and the fulfilment of specific SME needs
A Framework for Modelling Business Processes in a Collaborative Work Environment
No full textIn this paper it will be introduced the bxModeller functional changes. bxModeller is an open source web-based
application tool, that supports the Business Process modelling. These new functionalities will allow to widen the tool’s
modalities of use. A benchmark of different similar tools will be examined and motivations and their analysis will be
discussed. The objective is to improve the bxModeller and to make it proper to a collaborative environment, this will
allow to many users to contemporarily access at the same project, with an access mode defined by the affiliation profile,
more over it will enable the user to work and to make changes visible to others team’s partners in real time
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
