Abstract: With the development of software reuse technologies,more and more reusable software assets emerge on the Internet,such as Web Scrvices,JAR packages and so on. However,necessary description and using help information are often missed in these software assets. Therefore,we proposed an Internet based JAR package usage information collection method, which finds, reorganizes further, the description and the user commented corresponding to a JAR package.Based on this work,we implemented the usage information collection tool for JAR package in PKU Software Asset Repository. It has collected and organized description and user comment information for more than 6000 JAR packages.

Key words: Software asset,Software asset repository,JAR package,Usage information
