Knowledge map is a representation tool to visualize knowledge sources and relationships among knowledge artifacts, which is considered as a core element of knowledge management system. To construct a knowledge map, we need to identify which category each newly registered knowledge artifact is mapped into, called structured knowledge. However, in view of fully utilizing obtainable knowledge, it ...

The internet enables the rapid and easy creation, storage, and transfer of knowledge; however, services that transfer geographic knowledge and facilitate the public understanding of geographic knowledge are still underdeveloped to date. Existing online maps (or atlases) can support limited types of geographic knowledge. In this study, we propose a framework for map-based services to represent a...

In this article, a fast and reliable map-merging algorithm is proposed to produce a global two dimensional map of an indoor environment in a multi-robot simultaneous localization and mapping (SLAM) process. In SLAM process, to find its way in this environment, a robot should be able to determine its position relative to a map formed from its observations. To solve this complex problem, simultan...

Competition and globalisation are putting terrific pressure on organisations to provide a better quality service, to improve the speed to market, and to improve organisational agility and innovation. As organisations try to meet these challenges, they need to be innovative to produce the knowledge intensive services desired by their customers. As an organisation’s knowledge base comes to light,...

The bulk of research to date relating to intelligent tutoring systems (ITS) is focused on the student, and on methods for representing the knowledge itself. From student models to learning schemas to presentation methods, comparatively little attention has been paid to the problem of educators attempting to build viable curriculum plans for use in an ITS environment---yet when this problem is a...

We present in this paper a system for knowledge management in graphics recognition systems. This system is based on user approach through two man machine interfaces for “content-based” and “structure-based” knowledge management. With these two man machine interfaces, the users can browse, structure, and request the systems’ knowledge bases. This user approach illustrates than the knowledge is u...

This paper describes an open-ended and collaborative learning environment in WWW. In the environment called SharlokII, the learners provide and share individual knowledge and other knowledge on the WWW and discuss about them. This paper focuses on knowledge awareness map and its design, implementation and evaluation. The map visualizes the relationship between the shared knowledge and the curre...

This study explored the effects of prior knowledge (high vs. low; HPK and LPK) and concept-map structure (hierarchical vs. network; HS and NS) on disorientation, cognitive load, and learning from non-linear documents on ‘‘the infection process of a retrograde virus (HIV)’’. Participants in the study were 24 adults. Overall subjective ratings of disorientation and cognitive load, as well as deta...

Knowledge is represented by graph or map is simpler than represented by proposition logics. Students who use the knowledge representation of knowledge map quickly learn to read a graph as IF-THEN and do all their reasoning directly on the graphs without translating them to rules or propositions. Instead, many graphic notations have been developed. Knowledge Map (KM) is a graphic system of logic...
