چکیده
This paper reports on the design and development of an expert t%zzy classification scoring system for grading student writing samples. The growing use of ..m-iHm. .-sn..n..na +a,+, in ,k,e &&.a&rx sectoi WllCwz‘l ‘szqJ”ux LbaLU provides fertile domain areas for new and innovative applications of soft computing and expert systems technology. The main function of the expert firzzy classification scoring system is to support teachers in the evaluation of student writing samples by providing them with a uniform Eramework for generating ratings based on the consistent application of scoring rubrics. The system has been tested using actual student response data. A controlled experiment demonstrated that teachers using the expert fuzzy classification scoring system can make assessments in less time and with a level of accuracy comparable to the best teacher graders. The paper introduces frizzy classification techniques that can encapsulate knowledge about imprecise qmiiiies needed for cons~nct~g rn;e-‘ias& scorbg models that provide consistent, uniform scoring results. This increased consistency in the application of the scoring rubrics allows for more valid individual and group assessment.

متن کاملRisk Analysis in E-commerce via Fuzzy Logic
This paper describes the development of a fuzzy decision support system (FDSS) for the assessment of risk in E-commerce (EC) development. A Web-based prototype FDSS is suggested to assist EC project managers in identifying potential EC risk factors and the corresponding project risks. A risk analysis model for EC development using a fuzzy set approach is proposed and incorporated into the FDSS....
متن کاملIndirect Adaptive Interval Type-2 Fuzzy PI Sliding Mode Control for a Class of Uncertain Nonlinear Systems
Controller design remains an elusive and challenging problem foruncertain nonlinear dynamics. Interval type-2 fuzzy logic systems (IT2FLS) incomparison with type-1 fuzzy logic systems claim to effectively handle systemuncertainties especially in the presence of disturbances and noises, but lack aformal mechanism to guarantee performance. In contrast, adaptive sliding modecontrol (ASMC) provides...
