自适应教育超媒体系统的研制与实现
|
摘要
超媒体在教育、教学领域有着非常广泛的应用。本研究课题的重点是研究自适应教育超媒体的系统模型，在充分借鉴和参考国内外现有研究成果的基础上，从超媒体的自适应性及其特点入手系统地研究系统模型的各个层次，分析各种自适应技术的方法和策略，继而建立一个适用的自适应教育超媒体参考模型，该模型可以对不同用户的各种特征进行有效支持与适应，从而使教育超媒体软件得到更为广泛和高效的应用。分析总结系统模型是用户模型的各个层面，研究自适应教育超媒体系统中用户模型的建立过程，并设计一个用户模型实例，最终通过具体的实例来验证所提出的方法和模型的有效性。其主要研究内容如下：
(1)超媒体现状及其描述语言研究。
研究当前超媒体的应用现状及应用领域，进而研究超媒体在教育领域的实际应用，通过对超媒体的各种描述语言进行研究和比较，进而确定本课题所采用的描述语言。
(2)探索并提出自适应教育超媒体系统结构的参考模型。
通过对已有的教育超媒体系统的结构和功能分析，指出目前教育超媒体所存在的弊病，提出一种适应于自适应教育超媒体的系统结构参考模型，在建立系统结构参考模型的基础上进行分析。
(3)模型存储层中用户模型表示和更新的实现。
采用基于XML的文件存储用户模型。在存储层中，需研究以下内容：用户模型的各种信息的获取途径，用户模型的表示、初建与动态更新技术的研究与实现。
(4)自适应教育超媒体的实现。
利用已有建立好的系统结构模型和用户模型、应用一定的自适应规则设计一个教育超媒体的应用实例来验证所建立的模型的正确性。与已有的教育超媒体研究相比，本课题的新特点是：
(1)扩展了已有教育超媒体的系统模型，在模型存储层中增加了一个用户模型来实现系统的自适应性。
(2)建立了一个不定结构的用户模型，这样更能灵活地实现自适应算法，更能体现自适应的自适应特性。
Hypermedia is widely used on education area. The focal point of my research topic is to study the system model of self-adapting education hypermedia. Based on researching achievement of the world, I have made a systematic study for the different level of the system model starting from the self-adaptability and characteristic of hypermedia. Analyze all the various method and tactics of self-adapting technology. Establish a useful self-adapting education hypermedia reference model. This model can support and adapt all the various characteristic of different user. Thereby, the education hypermedia software can be widely and efficiently used. Analyze and summarize the different level of user model in system model, study the establishing process of user model in self-adapting education hypermedia, design an example of user model, finally prove the validity of the method and model. The main content as follow:
(1) The current situation of hypermedia and describing language study
Study the current situation and using area of hypermedia, study the application of hypermedia in education area, study and compare all the describing language of hypermedia, and determine the describing language for this research topic.
(2) Exploring and advancing the reference model of self-adapting education hypermedia system construction
Though the analysis for the exist construction and function of hypermedia system, point out the error of current education hypermedia. Advance a system construction reference model suiting for self-adapting education hypermedia. Make the analysis based on the establishing system construction reference model.
(3) Expression and renew of user model in model storage level
Use the file storage user model based on XML. In storage level, we must research the information getting method of user model, the expression of user model, initial establishment of user model. We must study and realize dynamic renew technology.
(4) Realization of self-adapting education hypermedia
Using the exist system construction model and user model by certain self-adapting rule, design an applying example of an education hypermedia for proving the correction of the establishing model.
Comparing with the former education hypermedia, the characteristic of my topic as follow:
(1) Expand the former system model. A user model is added in the model storage level for self-adapting of the system.
(2) Establish an indefinite construction user model, thus, self-adapting method can be realized flexibly, embodied easily, self-adapting method can be realized flexibly, embodied easily.
