digital library based on topic or concept features. Firstly, documents in a special domain are automatically produced by document classification approach. It integrates the rule-based and statistical method to classify the documents in the large-scale collection. Then, the keywords of each document are extracted using the
This paper is to introduce a new approach to build topic digital library using concept extraction and document clustering. Firstly, documents in a special domain are automatically produced by document classification approach. Then, the keywords of each document are extracted using the machine learning approach. The
