基于Nutch搜索引擎的E-learning系统开发

The Development of E-learning Based on Nutch Search Engine

针对现有的E-learning学习系统没有可供学习者搜索知识的功能,自带的检索也只能为学习者提供无差别的、千人一面的搜索结果,从而使学习者丧失学习兴趣的问题,设计和实现了一个新的E-learning系统.在开源的在线学习系统chamilo的基础上,将Nutch搜索引擎加入其中,实现了利用其搜索自身需要信息并得到与预想相匹配的结果.通过实验证明,该系统能提供学习者方便的知识搜索和更丰富的学习资源,提高学习者的学习效率和获得知识的能力.

The existing E-learning systems do not have the search function,or can only provide the same results even if having one,which makes the learners lose interest in learning.This paper,based on open source of chamilo E-learning system,designs and implements a new E-learning system in which Nutch system search engine is embedded.Its search function can be used to get the result of the match and the expected.The experimental results show that the system can provide learners with convenient search and more abundant knowledge of learning resources,and improve the learners＇ learning efficiency and ability to gain knowledge.
