Abstract
Recently, legal knowledge management (LKM) is one of the most important activities in every organization. However, practical LKM methodologies are not developed and only concepts such as "compliance" or "corporate governance" are popularized. In this article, we developed a program which relate each action to articles in laws automatically from the texts of laws. This program can visualize the law system, and improves the recall and precision of information retrieval of the articles in laws.
