Tailorable Representation of Security Control Catalog on Semantic Wiki
2018
Selection of security controls to be implemented is an essential part of the information security management process in an organization. There exist a number of readily available information security management system standards, including control catalogs, that could be tailored by the organizations to meet their security objectives. Still, it has been noted that many organizations tend to lack even the implementation of the fundamental security controls. At the same time, semantic wikis have become popular collaboration and information sharing platforms that have proven their strength as an effective way to distribute domain-specific information within an organization. This paper evaluates…
A Semantic Publish/Subscribe Approach for U-VR Systems Interoperation
2008
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure that lies on a description logics reasoner and OWL ontologies for managing heterogeneous event models and performing the matching of events and subscriptions in such U-VR systems.
A Social-Empowered Platform for Gathering Semantic Information
2013
Social Networks constitute the key ingredient for the huge success of the so called Social Web or Web 2.0. In social networks, a user has the possibility to interact with other users without the need of meeting them. The value of social applications benefit from the network effect, which states that the value of a service to a user arises from the number of people using the service. However, the associated semantics for this kind of applications, delivered through tagging, is generally scarce, thus narrowing the range of permissible operations for exploiting these data. In this paper, we present a semantic-based social platform that incorporates the benefits of semantic Web technologies int…
XBRL
2007
This paper describes the main contributions in relation with the develop of an XBRL (Extensible Business Reporting Language) taxonomy proposed by the PRISMA research group at University UNAB. This taxonomy has been developed for public institutions in Colombia. This taxonomy is based on the information exchange of financial information. It is also described the creation of a wiki system which includes real information of existing XBRL projects in the world and the creation of a demostration center of XBR reports.
Modeling Static Aspects of Mobile Electronic Commerce Environments
2011
Mobile phones and other small and powerful portable devices have revolutionized personal communication and affected the lifestyles of the people in the industrialized world. Following credible estimates, in a few years there will be one billion of such portable devices. An emerging trend is the electronic commerce performed using mobile terminals, often called mobile commerce. Mobile commerce environments are characterized by high complexity, including myriads of technical and organizational aspects. This property makes it difficult to distinguish the more fundamental issues, structures, and concepts in mobile commerce from the hype. To capture the fundamental aspects of mobile commerce env…
Presenting the Past: A Framework for Facilitating the Externalization and Articulation of User Activities in Desktop Environment
2006
Work processes are conducted in various contexts and they involve different tasks, interruptions, activities and actions. In all of these, tacit knowledge plays a part. Some part of that tacit knowledge can be externalized and articulated by continuously monitoring the users activities. Because the desktop environment is an integral part of almost any office work context, we chart the demands the unstructured and discontinuous nature of work puts on the management of desktop working context. We discuss possibilities to augment the users awareness of his/her desktop working environment by providing a context-aware application that can act as a map-like resource for the users past activiti…
The Adaptation of a Web Information System: A Perspective of Organizations
2011
We provide a different view on the problem of Web Information System (WIS) adaptation, looking from perspective of organizations that are interested in an adapted Web Information System for their needs if a unified system to support similar business processes is used. We propose an adaptation architecture for WIS. Two levels of adaptation are introduced—coarse grained adaptation for the organization level and fine grained adaptation for the user level. The architecture supports also the situation, when users can work with many instances of the system adapted for different organizations, which are integrated into one instance for a particular user.
EXPLORING THE EFFECTS OF DISCUSSION AND TEXT PLANNING STRATEGIES TO ENHANCE AND ASSESS WRITTEN COMMUNICATION SKILLS
2016
A scuola come nella vita, le capacità di comunicazione scritta sono fondamentali. Queste abilità riguardano soprattutto la costruzione di testi per usi e scopi diversi, l’elaborazione efficace delle informazioni, l’uso corretto della forma linguistica. Scrivere significa conoscere le regole grammaticali ma soprattutto riflettere sulle situazioni e sui contesti specifici di realizzazione, considerare le funzioni linguistiche, gli scopi e i bisogni comunicativi. Sempre più spesso lo sviluppo tecnologico alimenta le difficoltà di bambini e ragazzi di produrre discorsi corretti, coerenti e logicamente organizzati. Per promuovere e valutare la competenza espressiva scritta (strutturazione logica…
A structural comparison of halloysite nanotubes of different origin by Small-Angle Neutron Scattering (SANS) and Electric Birefringence
2018
The structure of halloysite nanotubes (Hal) from different mines was investigated by Small-Angle Neutron Scattering (SANS) and Electric Birefringence (EBR) experiments. The analysis of the SANS curves allowed us to correlate the sizes and polydispersity and the specific surfaces (obtained by a Porod analysis of the SANS data) of the nanotubes with their specific geological setting. Contrast matching measurements were performed on patch Hal (from Western Australia) in order to determine their experimental scattering length density for a more precise analysis. Further characterization of the mesoscopic structure of Hal was carried out by Electric Birefringence (EBR), which allowed to study th…
