OntoWeaver S: supporting the design of knowledge portals

This paper presents OntoWeaver-S, an ontology-based infrastructure for building knowledge portals. In particular, OntoWeaver-S is integrated with a comprehensive web service platform, IRS-II, for the publication, discovery, and execution of web services. In this way, OntoWeaver-S supports the access and provision of remote web services for knowledge portals. Moreover, it provides a set of comprehensive site ontologies to model and represent knowledge portals, and thus is able to offer high level support for the design and development process. Finally, OntoWeaver-S provides a set of powerful tools to support knowledge portals at design time as well as at run time

Collaborative Environments. Considerations Concerning Some Collaborative Systems

It is obvious, that all collaborative environments (workgroups, communities of practice, collaborative enterprises) are based on knowledge and between collaboration and knowledge management there is a strong interdependence. The evolution of information systems in these collaborative environments led to the sudden necessity to adopt, for maintaining the virtual activities and processes, the latest technologies/systems, which are capable to support integrated collaboration in business services. In these environments, portal-based IT platforms will integrate multi-agent collaborative systems, collaborative tools, different enterprise applications and other useful information systems.collaboration, collaborative environments, knowledge management, collaborative systems, portals, knowledge portals, agile development of portals

ENTERPRISE INFORMATION PORTALS VS. ENTERPRISE KNOWLEDGE PORTALS

An "enterprise portal" a platform intranet access to corporatedata and system resource information together in one place.The enterprise portal is the gateway to the information systemof the enterprise for all staff and eventually partners. The issueof the portal is to seek to focus the user within the systemThe enterprise portal is the gateway to the data system Thisarticle's main objective is to develop a comprehensive anda balanced overview of the technical information portal andbusiness management knowledge, while showing how they arelikely to enhance productivity and accelerate innovation in theenterprise. Hummingbird hopes to help you identify many ofthe technologies that underpin the management of knowledge, while giving you a maximum element to support yourdecision-making process.On appelle "portail d'entreprise" une plate-forme intranetdonnant accès à des données de l'entreprise ainsi qu'à desressources du système d'information regroupées au sein d'uneinterface unique.Le portail d'entreprise est ainsi la porte d'entrée vers les données dusystème d'information de l'entreprise pour l'ensemble du personnelet éventuellement les partenaires.

Investigation for Success Factors In Using Portals as a Knowledge Sharing Mechanism

Defining the concept of portal as a framework for integrating information, people and processes across organizational boundaries through software solution installed on organization infrastructure which may include internet, intranet, and extranet network. Portals play importance role in knowledge sharing and management as a gateway to all unstructured, structured, and collaborative information and knowledge within organization so that the user can easily work on this personalized platform. Firstly, i would like to explain the functions of some important concepts like portals and knowledge sharing. Furthermore, I will also explain the role of portals in knowledge sharing process and how it can improve the knowledge management in the organization. This paper will discuss and focus on the success factors for excellent portal implementation and how to use the portal to achieve knowledge sharing in the organization. In conclusion, I will determine the success factor on using portal as knowledge sharing tool and how it can improve the knowledge management overall in the organization and how the portal becomes strong point in the organization to publish knowledge sharing culture and support decision making. As Example for the portals, I’ll explain some features for MS SharePoint. Keywords: knowledge management, Portals , MS SharePoin

A model for knowledge portal to support communities of practice

Communities of practice (CoP) are groups of individuals with common interest who communicate and share knowledge among their respective group. The use of knowledge portals for CoP will assist the exchange of knowledge, thus it promotes the learning process. Nevertheless, such portals may encounter many challenges to draw the interest among the members in sharing their knowledge voluntarily. As the result, the portals face inactive participants among the members. Knowledge sharing system such as knowledge portal is useless without knowledge sharing activity among its members. In order to encourage users to share their knowledge, we first must uncover the underlying problems on why the users are reluctant to share their knowledge through the knowledge sharing system. This paper reviews the current obstacles in knowledge sharing among CoP and proposes a model to support the needs that software engineers may consider when designing a knowledge portal

Technology for Ontological Engineering Lifecycle Support

The research is partially supported by Russian Foundation for Basic Research (grants 06-01-81005 and 07-01- 00053)Presented paper describes software system project ONTOLINGE-KAON that provides technological support for the whole lifecycle of ontological engineering. The main stress is put on the evaluation of maturity and quality of ontologies and on the usage of ontologies with the help of automated generation of knowledge portals, based on ontologies. Possibility of creation of knowledge portals built on top of ontologies can become a big step forward in the field of e-learning. The paper presents advantages provided by knowledge portals based on top on ontologies

Bunte Blumenwiese versus Nutzbarkeit - Virtuelle Fachbibliotheken und andere Fachportale im Kontext von vascoda und Möglichkeiten der Homogenisierung

The German Research Foundation (DFG) and the Federal Ministry for Education and Research have funded the establishment of subject-specific portals since the end of the 1990s. Currently, there exist at about 40 portals for each academic field. These subject portals are aligned to the specific user needs in research and teaching. This means that each portal has its own characteristics, but all of them offer the same core of services, e.g., literature search, catalogue of internet resources, etc. All portals can be searched via vascoda.de that offers a meta-search. The German National Library of Economics (ZBW) is engaged in two projects related to these portals: First, the project "Knowledge Transfer for Subject Portals" organises workshops and provides support for new portals. The main objective is to achieve a better homogenisation of the individual portals. Second, the ZBW is participating in an external study that assesses the relevance of the portals for the target group. This paper reports on the status quo of the portals in the light of these two projects. Finally, possible further developments are outlined

Measuring Mobile Portal User Satisfaction

With the rapid advancement of mobile technology, smart devices have challenged the extant research concerned with time and space. Based on a user’s specific interests, mobile portals allow quick and easy access, anywhere, anytime to a world of data, applications and services. Whilst this provides an enhanced, dynamic and personalized user experience, knowing how satisfied users are with their mobile portal is crucial to understanding users’ needs, identifying important factors in the improvement of existing mobile portals and enhancing Information Technology (IT)-related business value. The study extends research knowledge about user satisfaction to the context of mobile portals. Secondly it contributes knowledge regarding mobile portals, particularly concerning post-adoption mobile portal user satisfaction. Thirdly, the research contributes a new reliable and valid instrument to measure user satisfaction with mobile portals – a contribution to the research stream within the IS literature concerned with measurement
