Multi-document Summarization for E-Learning

摘要

As a large amount of learning materials available in e-learning, automatic summarization has been utilized in digital library for e-learning. Multi-document summarization extracts information from multiple texts documents. It improves the effectiveness of retrieval and accessibility of learning materials in e-learning. Related study has shown that hierarchical summarization is a promising technique. Hierarchical summarization has been extended to summarization of multiple documents. This paper investigates the impact of organization of documents on hierarchical summarization. Automatic document clustering technique is developed for organization of learning materials. A multi-document hierarchical summarization system is developed based on these techniques. The system provides an essential tool for e-learning.
