Using a User-Interactive QA System for Personalized E-Learning

Abstract

A personalized e-learning framework based on a user-interactive question-answering (QA) system is proposed, in which a user-modeling approach is used to capture personal information of students and a personalized answer extraction algorithm is proposed for personalized automatic answering. In our approach, a topic ontology (or concept hierarchy) of course content defined by an instructor is used for the system to generate the corresponding structure of boards for holding relevant questions. Students can interactively post questions, and also browse, select, and answer others’ questions in their interested boards. A knowledge base is accumulated using historical question/answer (Q/A) pairs for knowledge reuse. The students’ log data are used to build an association space to compute the interest and authority of the students for each board and each topic. The personal information of students can help instructors design suitable teaching materials to enhance instruction efficiency, be used to implement the personalized automatic answering and distribute unsolved questions to relevant students to enhance the learning efficiency. The experiment results show the efficacy of our user-modeling approach.

Influence of online learning skills in cyberspace

“…suburban areas), countries, or even those in the same urban area universities offering dissimilar e‐learning models (e.g. Dahl and Vossen, 2008; Lu and Yeh, 2008; Hu et al , 2008; Sivakumar and Robertson, 2004). Therefore, the current data collected from the particular organizations in Taiwan may not be fully representative of other scenarios.…”

A -calculus-based Complaint Model for a User-interactive Question Answering System

“…[2] defined semantic patterns for questions and answers in multi-user interactive QA systems. [3] applied a multi-user interactive QA system for personalized E-Learning. [4] proposed an approach to obtain the knowledge requirement of users using an interaction QA system.…”

“…[5] studied the user reputation model for a userinteractive QA system. On the basis of our previous work [1][2][3][4][5], this paper focuses on the complaint model of the multiuser interactive QA system. Figure 1 shows the framework of the multi-user interactive QA system [2][3] .…”

“…On the basis of our previous work [1][2][3][4][5], this paper focuses on the complaint model of the multiuser interactive QA system. Figure 1 shows the framework of the multi-user interactive QA system [2][3] . The basic process of the system interacting with the user is described as follows: Users ask questions in the system and set certain rewards for their questions.…”

Short Text Similarity Computing Method towards Agriculture Question and Answering Systems

“…Question and answering system (QA) is concerned more and more in recent years [1,2] . In QA system, the real-time performance and efficiency of the research can be improved by communicating with users, which is the so-called user interactive system [3,4,5] . Agriculture interactive QA relies on the participation of the users to find a proper way to solve the problems user encountered in the process of agricultural production.…”
