ion Heuristic Match Solutions Refinement Solutions Abstractions Fig. 1. Clancey’s heuristic classification model. Clancey’s analysis of rule-based systems provided an important milestone in knowledge engineering. He showed that a knowledge-level analysis [2] makes it possible to focus on what a system actually does, rather than how it does it. In other words we have a shift from an emphasis on ...

Knowledge engineering research have thoroughly considered the problem of distributed knowledge acquisition and management over the last decades. In this paper, we claim that the success of the Web 2.0 platforms in conjunction with semantic technologies will have an impact on distributed knowledge engineering. Especially, (extended) semantic wikis offer a well–accepted tool allowing for a simpli...

captured knowledge must then be made available throughout the organization in a timely manner. In terms of technology, most current knowledge management activities rely on database and Internet systems. If knowledge is stored explicitly at all, it is typically in databases either as simple tables (for example, relational databases) or semistructured text (as in Lotus Notes). The use of sophisti...

Knowledge management facilitates the capture, storage, and dissemination of knowledge using information technology. Methods for managing knowledge have become an important issue in the past few decades, and the KM community has developed a wide range of technologies and applications for both academic research and practical applications. In this paper, we propose a knowledge engineering approach...

graduates of science and engineering have almost similar background in science, mathematics and computation, with this difference that science graduates use their knowledge to explore and increase our understanding of the nature, while engineers apply that knowledge to design products, processes and structures that satisfy the needs of society. studies show that some students are interested in ...

The objectives of this study were to investigate Engineering students’ attitudes and problems in academic reading comprehension and to determine the contribution of academic reading attitude, breadth and depth of vocabulary knowledge to academic reading comprehension. The participants were 122 undergraduate students of Engineering at Iran University of Science and Technology. The Vocabulary Lev...

The paper presents a scheme for categorizing knowledge engineering tools. The classification of knowledge acquisition systems has revealed some interesting facts about these systems. It seems that systems which are able to work on multiple tasks produce very shallow (i.e., not of expert-level) knowledge bases. On the other hand, systems which produce expert-level knowledge bases function on a s...

The development of knowledge-based systems requires the availability of domain and problem-solving knowledge. This knowledge must be acquired from domain experts. For this purpose the paper proposes to adopt the concept of scenarios known from requirements engineering and object oriented modelling to enrich the set of acquisition techniques. In RE and OO scenarios are used to define a vision of...
