E-government means using information and communications technologies to improve the transparency, efficiency, and effectiveness of public institutions. The government can provide many convenient online services to serve the civil well. Especially, many local governments in Taiwan have used ”Mayor's Email-box” to handle citizen complaints or opinions. Quick responses to those complaints or opinions are needed in e-government services. Therefore, to classify the citizens' opinions quickly and correctly has become an import work for the government. Through interview with the domain experts, we found that ”knowledge map” can improve the efficiency of classification system which was ignored before.This study proposes a framework which contains two phase works. First, the knowledge map should be built up based on the association rules discovered from the training data. Next, the unclassified documents will be categorized according to the knowledge map.To verify the proposed framework efficiency and accuracy, extensive experiments are conducted using real data sets. The experimental results indicate that the proposed method is computationally efficient, and can effectively categorize documents.
