A computer-supported learning system to help teachers to teach Fuzzy Information Retrieval Systems

Abstract

This paper describes a computer-supported learning system to teach students the principles and concepts of Fuzzy Information Retrieval Systems based on weighted queries. This tool is used to support the teacher's activity in the degree course Information Retrieval Systems Based on Artificial Intelligence at the Faculty of Library and Information Sciences at the University of Granada. Learning of languages of weighted queries in Fuzzy Information Retrieval Systems is complex because it is very difficult to understand the different semantics that could be associated to the weights of queries together with their respective strategies of query evaluation. We have developed and implemented this computer-supported education system because it allows to support the teacher's activity in the classroom to teach the use of weighted queries in FIRSs and it helps students to develop self-learning processes on the use of such queries. We have evaluated the performance of its use in the learning process according to the students' perceptions and their results obtained in the course's exams. We have observed that using this software tool the students learn better the management of the weighted query languages and then their performance in the exams is improved.

A Web-Based Learning Support System for Rough Sets

“…For fuzzy information retrieval systems, a simulator is developed to visualize the steps of weighted queries in a graduate course [22]. It aims to solve the problem that a blackboard is very difficult to visualize the content of weighted queries and fuzzy connectives.…”

“…In post-secondary education, there are some Web-based learning systems for computer science subjects, such as, artificial intelligence, network security, information retrieval, theory of computation, robotic, and system analysis [8,21,22,26,33,34,48,49]. However, there are no Web-based learning systems for rough sets in the literature.…”

“…22: A study plan containing the learning sequence and estimate time The learning sequence guides students to learn concepts one by one rationally. It has considered dependency among concepts, a student's goal, experience, and preference.…”

A Review on Information Accessing Systems Based on Fuzzy Linguistic Modelling

“…An educational software tool to teach fuzzy linguistic IRSs was implemented in 89 . The main purpose of this tool is to assist students and non-expert users in the complex process of learning the performance of the fuzzy weighted IRSs based on FLM.…”

Evaluación de mapas de competencias educativas: una propuesta difusa basada en 2-tuplas

“…Con el propósito de abordar el problema mencionado, el presente artículo propone un enfoque difuso para evaluar competencias, basado en la estructura y características de los mapas de competencias usando el enfoque de 2-tuplas lingüísticas. El enfoque difuso es usado porque permite una mejor representación del lenguaje natural (Herrera, López, Alonso, Moreno, Cabrerizo & Porcel, 2009). Adicionalmente, en este trabajo se desarrolló una herramienta Java basada en la propuesta, la cual se encarga de computar los NC de todas las competencias de los mapas mientras mide y presenta los tiempos de ejecución utilizados.…”
