Knowledge EXplorer is a system for exploratory analysis and knowledge acquisition in categorial data. The knowledge acquisition component induces knowledge in the form of weighted rules. These rules can be directly used in an PROSPECTOR like expert system.

We present a tool for detecting conflicts and redundancies among large knowledge bases. First it allows the reduction of the combinatory by selecting among all the rules only those liable to generate conflicts ; it does this using properties of the rules and heuristics. Then some attributes linking chunks of knowledge constitute access paths allowing to reduce the search duration for a particul...

Information on technical knowledge has become, with the industrial productive process expansion, a basic factor for the reproduction of capital. In such a context, Information is achieving an ever growing political characteristic leading to the division of the world into information-poor countries and information-rich countries. In spite of its potential as a development tool for the countries,...

This paper presents an approach for structured decomposition of knowledge in certain problem domains, which can be classified as knowledge-based business processes. Knowledge in such problem domains is already partly formalized, and allows natural functional decomposition; however, it is complex enough to justify knowledgebased implementation of process execution. Examples include, in addition ...

This study examines the effect of co-elaborating a knowledge model in dyads at a distance on performance and on learning. Participants (N = 48) were trained to represent knowledge taken from a text, using an object-typed knowledge modeling editor software tool. Knowledge modeling is similar to concept mapping, except that the former is based on a typology of knowledge objects and a typology of ...

This research study deals with the early design and planning of manufacturing systems, following a knowledge reuse approach. The proposed approach introduces a knowledge based framework that facilitates the definition, storage and extraction of knowledge in terms of past production process configurations. The semantic technology and artificial intelligence approaches, such as inference rules an...

The problem of acquiring procedural knowledge for hull form design and construction of a knowledge base for hull form selection is addressed in this paper. An object oriented methodology involving creating classes, state diagrams and data flows for parametric hull form design was undertaken. An interactive graphical tool for the production of hull designs from a parent design was developed base...

This paper describes the development of a software tool to support knowledge acquisition by means of rich pictures, for Object Oriented Analysis (OOA). Transposition of manual rich picture practise into software proved difficult, therefore we decided to follow a user-centered approach, design and implement a prototype with basic functionalities, then run a usability test with a few students and...

Note taking is a fundamental activity for learning, and many software tools which enable students to take digitized notes have been proposed. Digitized notes are advantageous because they can be easily edited, rearranged, and shared. Although many note-taking tools have been proposed, there has been little research to examine the effect of note rearrangement with a digitized tool in terms of kn...
