A fuzzy collaborative assessment approach for knowledge grid

The assessment of Knowledge Grid is important to its design, development and maintenance. The difference between Knowledge Grid and website in structure and content determines that the current website assessment approaches are not suitable for assessing the Knowledge Grid. This paper proposes a fuzzy collaborative assessment approach combining the objective and subjective assessment strategies. The objective assessment strategy integrates the criteria used in website assessment and those related to knowledge organization and management. The subjective assessment strategy assesses the quality of knowledge service through the cooperation between experts and agents. The proposed approach also provides the optimum solution for improving the performance of the Knowledge Grid based on the assessment result and constraints. We demonstrate the proposed approach through a real application. (C) 2003 Elsevier B.V. All rights reserved.
