Nowadays, we face a huge amount of data and information sharing on the Web by different users worldwide. A multidimensional perspective in describing a university ontology seems to be very important for the modelling of higher education resources. This paper proposes a multi-dimensional knowledge model, designed to distribute and manage knowledge resources efficiently. We propose our model as the foundation of an advanced knowledge platform including the following dimensions: time, area and social. Three crucial domains should be considered in this model: educational, research and managerial. The ontology including the mentioned knowledge management aspects is prepared using Ontorion Fluent Editor.

Data Mining (DM) is a very crucial issue in knowledge discovery processes. The basic facilities to create data mining models were implemented successfully on Oracle 9i as the extension of the database server. DM tools enable developers to create Business Intelligence (BI) applications. As a result Data Mining models can be used as support of knowledge-based management. The main goal of the paper is to present new features of the Oracle platform in building and testing DM models. Authors characterize methods of building and testing Data Mining models available on the Oracle 9i platform, stressing the critical steps of the whole process and presenting examples of practical usage of DM models. Verification techniques of the generated knowledge bases are discussed in the mentioned environment.

Abstract-Exclusion phenomenon in common understandingdenotes processes in which some group of people or individuals are permanently blocked from resources (mostly considered as social exclusion). For sure such sort of phenomena is observed as unwanted not only from "outsiders" but also from local and global society point of view. The exclusion (and its antonym inclusion) phenomenon can be investigated including many aspects: starting from identifying exclusion as a process, multidimensional research in this area up to solutions available in the domain. In order to be successful in overtaking this phenomenon groups and institution involved in this process should be supported by ICT solutions. The paper consists of five parts which gradually present context of the problem and proposed solutions. After short introduction concerning research background the discussed concept of exclusion processes is presented. In the main section real examples of exclusion processes are investigated which allows to define assumptions of knowledge portal architecture and some examples of performed services. It creates opportunities for formulation final conclusions about the necessity and usability the developed platform.

Distance learning improves access to education and - in most cases - advances the quality of education delivery. Its key attributes are: openness, interactiveness and using multimedia teaching materials allowing: learning by anybody, at any place and anywhere. In order to assure high quality of learning, the offered courses should satisfy audience expectations and should convey knowledge in modern ways. To analysing teaching effectiveness we have evaluated a number of distance education courses. The paper describes evaluation aspects of distance learning environment and proposes the following criteria useful for this task: knowledge completeness, consistency and adequacy. Apart from knowledge passing, we have to deliver courses in an attractive form. We propose guidelines useful for evaluation of courses prepared in the LearningSpace (Lotus Notes application) environment s. The quality of education can be greatly improved by following these guidelines Two of the courses designed for MBA studies: "Business Plan Preparation” and " Management Decision Support Systems" illustrate the usability of the course evaluation method.

Part 2: Models and Functioning of Knowledge ManagementInternational audienceExclusion phenomenon in common understanding denotes processes in which members of society or groups of people are permanently blocked from resources (mostly considered as social exclusion). No doubts, such sort of phenomena is observed as unwanted not only from “outsiders” but also from local and global society points of view. The exclusion (and its antonym inclusion) phenomenon can be investigated including many perspectives: starting from identifying exclusion as a process, through multidimensional aspects up to solutions available in the domain.In order to be successful in overtaking this phenomenon groups and institutions involved in this process should be supported by ICT solutions. The paper consists of six parts which gradually present context of the problem and proposed solutions. After short introduction concerning research background the discussed concept of exclusion processes and knowledge portals are presented. In the main section a general idea of knowledge portal for exclusives is proposed and specialty of these portal for regional implementation in the Silesia agglomeration is discussed. It creates opportunities for formulation final conclusions about the necessity and usability of the developed platform
