The Role of Data Warehouse as a Source of Knowledge Acquisition in Decision-Making. An Empirical Study

Part 1: Tools and Methods for Knowledge AcquisitionInternational audienceThe main purpose of conducting this research is to investigate empirically the role and importance of data warehouse (DW) in enhancing the effectiveness of decision-making. It is believed and assumed that meaningful and significant information can be acquired from DW which provides valuable knowledge to support business process and decision-making. A mail questionnaire survey was regarded as the appropriate method for gathering data. The questionnaire was developed based on the findings from related literature and other related research questionnaires. All the firms (277), which were listed on Amman Stock Exchange (ASE), at the time of data collection, were selected. The researchers arrived at scores of significant and remarkable results regarding DW and its role in enhancing the process of decision-making. The survey’s findings showed that the percentage of implementing DW in the Jordanian firms involved is 35 %. In general, the respondents had a positive attitude towards the implementation of DW

Adaptive Agent Systems in Contemporary e-Commerce Environment

Ewolucja priorytetów konsumenckich, ukierunkowana na oszczędność czasu transakcji, spersonalizowane podejście i ogólne odejście od ceny jako jedynego i najważniejszego wyznacznika jakości produktów i usług spowodowały nasilenie dynamiki zmian zachodzących w handlu elektronicznym. Zdeterminowało to konieczność zastosowania technologii, która w sposób efektywny sprostałaby wymogom stawianym przez analizowany rynek. Technologią taką są inteligentni agenci programowi. Autorzy, poprzez wyróżnienie wybranych zastosowań systemów tej klasy w obszarze analizowanego rynku, wskazują na cechę adaptacyjności jako kluczową dla sprawnego i efektywnego funkcjonowania tych systemów. Niniejszy artykuł prezentuje różne podejścia do kwestii adaptacyjności, która jest odpowiedzią na konieczność dostosowania się agentów do dynamiki zmian zachodzących w środowisku e-commerce. Wymóg taki wynika zarówno z potrzeby modyfikowania swojego zachowania w reakcji na bodźce płynące z otoczenia, jak i z interakcji z innymi agentami w systemach wieloagentowych.The evolution of consumer priorities focused on time-saving transactions, a personalized approach and the general move away from price as the sole and most important determinant of the quality of products and services have resulted in intensification of dynamic changes in e-commerce. This determined the need for technology which would effectively meet the requirements set by the market. Such a technology are intelligent program agents. The authors, through the award of selected applications of this class of systems in the analyzed market, indicate adaptability as a key for their efficient and effective functioning. This article presents different approaches to the issue of adaptability, which is a response to the need for agents to adapt to dynamic changes in the environment of e-commerce. Such a requirement is clear both from the need to modify their behavior in response to stimuli from the environment in which they operate and from the interaction with other agents in multi-agent systems

Usability of Knowledge Portals for Exclusives in Local Governments

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

Innovation in the construction of educational systems balancing the supply-demand of PhD candidates. An initial research survey

Nowadays, the requirements and expectations of universities are increasing along with globalization. The functions of Research and Development and the doctorate programmes which aim to support education and train the academic staff, came to the fore with globalization. The doctorate programmes in European countries cannot be updated fast enough and quotas for these programs are insufficient in some regions – faster balancing seems to be the must. The Decision Support System (DSS) can be a solution to the problem. In this study, the candidates’ demand of the universities, the public-private organizations and R&D centres are included to a model. As a result DSS will help us identify the need for candidates and develop PhD planning strategies by analysing the current situation of the university policies through the innovative model balancing the supply-demand for PhD candidates – including formulae of doctorate implementation (recently introduced in Poland)

Usługi dla osób wykluczonych w miejskich platformach wiedzy

Exclusion phenomenon denotes processes in which some group of people or individuals is permanently blocked from resources (mostly considered as social exclusion). The discussed phenomenon can be considered in many aspects: identifying exclusion as a process, multidimensional research in this area and presenting solutions useful in solving problems. Real support of the processes in overtaking exclusion phenomenon can be offered from Information and Communication Technologies area. The aim of this paper is the presentation of smart city portals content in order to support services devoted to exclusion processes neutralization. Several existing portals of selected smart cities are taken into account. The contents of the research sample will be analysed to investigate the state of the art solutions in the area and confronted with the concept of knowledge portal. The paper consists of five parts, including Introduction and Conclusions. The three merit parts describe exclusion phenomena, then general concept of knowledge portal devoted to services is presented and the last part demonstrates existing solutions in this area
