Comparing the applicability of two learning theories for knowledge transfer in information system implementation training
2004
This study reviews two traditional learning theories from the viewpoint of knowledge transfer in information system implementation training. The main goal of this study is to determine which is more applicable from the view of knowledge transfer in this context. In this study, behaviourist learning theory is found suitable for the transfer of data and information. Being more learner-centered, constructivist learning theory suits better for information system implementation training, as it enables combining system specific knowledge with knowledge of the existing organisational processes. This creates new organisation-specific knowledge necessary for the effective use of the information syst…
A review of the main approaches to knowledge management
2008
The purpose of this paper is to order and connect different perspectives on the creation and management of knowledge. Several proposals for the classification of the main approaches to knowledge management are considered and their connections and differences discussed. Three main groups emerge: measuring knowledge, managing knowledge (either with greater emphasis on the human factor or on information technologies) and creating knowledge. After selecting and analysing selection of the most relevant studies in this area, these concepts can be arranged into a continuum from a more descriptive perspective to a more normative one. The main contribution of this study is the compilation of literat…
Knowledge Representation in Extended Pawlak’s Information Systems: Algebraic Aspects
2002
The notion of an information system in Pawlak's sense is extended by introducing a certain ordering on the attribute set, which allows to treat some attributes as parts of others. With every extended information system S associated is the set K(S) of those pieces of information that, in a sense, admit a direct access in S. The algebraic structure of the "information space" K(S) is investigated, and it is shown, in what extent the structure of S can be restored from the structure of its information space. In particular, an intrinsic binary relation on K(S), interpreted as entailment, is isolated, and an axiomatic description of a knowledge revision operation based on it is proposed.
Where to acquire knowledge: Adapting knowledge management to financial institutions
2016
Abstract This research seeks to determine which sources of knowledge have the greatest effect on financial entities' knowledge acquisition and management. A review of the literature on knowledge management examines four key knowledge sources: Human resources, organizational management, technology adoption, and the business environment. The study performs pairwise comparisons of variables through the analytic hierarchy process (AHP), using a scale that captures the importance of each criterion, thereby simplifying the decision process. Results show that human resources and new technology adoption are the most effective sources of knowledge acquisition and management. Specifically, one of the…
Search for excited leptons in Z0 decay
1990
Due to the severity of system-wide power outages, though their probability of occurrence is slight, regulatory authorities require that a system restoration plan be drawn up and kept up to date at all times. The power outage that affected northeastern North America in 2003 proved the need for such a requirement. The particular structure of Hydro-Quebec's power system requires the use of a highly specific system restoration procedure. The daily preparation of the system restoration plan is based on a strategy whose application requires that a restoration sequence be drawn up that uses available equipment, the electrical behavior of which has been validated using appropriate studies. Over the…
Use and Identification of Components in Component-Based Software Development Methods
2000
New software systems are needed ever more but to keep up with this trend software developers must learn to create quality software more efficiently. One approach is to (re-)use components as building blocks of the new software. Recently there has been more interest to create component-based software development methods to support this. In this article we first set out requirements for reuse-based software development and then evaluate three component-based methods, namely Catalysis, OMT++, and Unified Process. As a conclusion we argue that evaluated methods produce prefabricated components and that component-based means that software developers can change better components to existing syste…
Digital Teaching Competence Evaluation of Pre-Service Teachers in Spain: A Review Study
2021
Digital teaching competence is one of the main teacher training needs today. However, teacher training curricula show a significant gap in this area. The objective of this study is to carry out a systematic review of scientific articles published between 2011 and 2020 that analyze the digital teaching competence of pre-service teachers who are mainly studying in Spanish universities. The reviewed studies show that there is great heterogeneity in the theoretical frameworks and instruments employed. Pre-service teachers point out that they have certain digital skills, but they lack pedagogical skills to digitally enrich the teaching-learning processes. These aspects present challenges in rese…
Knowledge engineering and semantic formalism of symbolic relations. From medieval network to web 3.0
2020
A search has always been at the center of human concerns, the one of conditions and means to represent, to control well, and to communicate effectively with his environment. While technological advances and electronic gadgets such as smartphones, the Web, and online social networks currently allow addressing this concern, it has not always been the case. Our works in this thesis treat medieval documents considered as a medium of communication and as a model of the social network in the Middle Ages. These documents are called medieval illuminations. They were luxurious paintings used in that time to represent the environment and ideal world for elites such as prince, duke, etc. Those paintin…
Reports of the AAAI 2019 Spring Symposium Series
2019
Applications of machine learning combined with AI algorithms have propelled unprecedented economic disruptions across diverse fields in industry, military, medicine, finance, and others. With the forecast for even larger impacts, the present economic impact of machine learning is estimated in the trillions of dollars. But as autonomous machines become ubiquitous, recent problems have surfaced. Early on, and again in 2018, Judea Pearl warned AI scientists they must "build machines that make sense of what goes on in their environment," a warning still unheeded that may impede future development. For example, self-driving vehicles often rely on sparse data; self-driving cars have already been …
A Knowledge Management System using Bayesian Network
2009
In today's world, decision support and knowledge management processes are strategic and interdependent activities in many organizations. The companies' interest on a correct knowledge management is grown, more than interest on the mere knowledge itself. This paper proposes a Knowledge Management System based on Bayesian networks. The system has been tested collecting and using data coming from projects and processes typical of ICT companies, and provides a Document Management System and a Decision Support system to share documents and to plan how to best use firms' knowledge.
