Ontological supports of knowledge: knowledge creation and analytical knowledge
2011
PurposeThe purpose of this paper is to examine, from the perspective of different theoretical approaches, the relationship that exists between different ontological supports of knowledge and knowledge itself (the way it is created and its characteristics).Design/methodology/approachThe paper proposes two different types of knowledge (knowledge of concrete situations and abstract knowledge) and two approaches (the constructivist view and the cognitive view) and provides a general classification of the different knowledge types. Second, it examines the underlying ontological support‐knowledge creation, characteristics or types of knowledge relationship in different approaches. Finally, conclu…
Knowledge management challenges in knowledge discovery systems
2006
Current knowledge discovery systems are armed with many data mining techniques that can be potentially applied to a new problem. However, a system faces a challenge of selecting the most appropriate technique(s) for a problem at hand, since in the real domain area it is infeasible to perform a comparison of all applicable techniques. The main goal of this paper is to consider the limitations of data-driven approaches and propose a knowledge-driven approach to enhance the use of multiple data-mining strategies in a knowledge discovery system. We introduce the concept of (meta-) knowledge management, which is aimed to organize a systematic process of (meta-) knowledge capture and refinement o…
Introduction to the Management of Knowledge Systems Design and Deployment Projects Minitrack
2012
Knowledge systems are increasingly used to support globally distributed work. Projects are a natural means of designing and deploying such systems. There is plenty of literature on the management of information systems design projects and some literature on information systems deployment projects. However, knowledge systems are typically more complex organizationally and socially than most traditional information systems. For example, enterprise resource planning systems typically must be used to get the work done whereas many knowledge systems are voluntary to use. It is reasonable to assume that project management involved in the design and deployment of knowledge systems differs from the…
A model to assess the behavioral impacts of consultative knowledge based systems
1997
This paper develops a research model to study the behavioral impacts of consultative knowledge based systems (KBS). An experiment was conducted with 36 experienced MBA students in marketing management to explore to what extent their decisions were affected by the following factors: user participation in updating the knowledge-base of the KBS, ambiguity of decision setting, routinization of usage, and source credibility of the expertise embedded in the KBS. Results show that ambiguity and source credibility affect user acceptance of the KBS recommendation and cause them to revise decisions. Implications of these findings for the design of consultative KBS are discussed.
Introduction to Designing and Deploying Advanced Knowledge Systems Minitrack
2015
The objective of this minitrack is to contribute to the body of knowledge that helps academics and practitioners to design, deploy and evaluate advanced knowledge systems, explore and leverage appropriate project management methods and tools for designing and deploying knowledge systems, and study changing organizational knowledge processes and structures.
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…
Introduction to semantic knowledge base: Linguistic module
2013
Following paper presents main concepts of Semantic Knowledge Base in particular linguistic module. The main assumption is to develop solution that would be easily adoptable by various languages. The module design will be presented in Association Oriented Model to maintain inner compatibility of the Knowledgebase.
Analysis and validation in design time of distributed control systems implemented by means of rule based expert systems
2005
In this paper a new analytical method for control systems validation is presented. The control system will be implemented by means of expert systems based on rule nets, which are a formalism that seeks to express an automatism in a similar way to as would make it a human being: "IF antecedents THEN consequent". But at the same time rule nets are a tool for the design, analysis and implementation of rule based systems (RBS), and consist on a mathematic-logical structure which analytically reflects the set of rules that the human expert has designed. The validation consist on the analysis of the decisive rule nets properties in design time. This properties have been studied and formalized com…
A Novel User Interface for Knowledge Base Browsing
2019
Abstract Intuitive user interfaces have been of great concern for GUI developers. The current research, who deals with their designing, faces the term intuitive constantly. The main question is how can the Interface be intuitive? For the moment, the researchers try to provide a very intuitive generic user interface that can be used in a variety of applications. In this paper we provide a solution that can model any applied ontology into a honeycomb menu. The hexagonal shape of the honeycomb has attracted the attention of humans for centuries. As a relevant consequence, the final user can browse any knowledge base very easily with the aid of this interface. Another useful feature is that pro…
