英文摘要: With the fundamentals of the research findings of years on data mining of the applicant, this project takes rough set and fuzzy theory as the main part based on the monitoring and management of hazardous chemicals transportation with the information sources from practical business information system of hazardous chemicals transportaion to solve knowledge acquisition problems in the safety management of hazardous chemicals transportation with uncertain information. Research priorities are as follows. I. Rough set theory is applied to reduce dimensions of multi-dimensional uncertain information in resolving its knowledge representation; fuzzy concept lattice is introduced to broaden its research of knowledge reduction and acquisition. II. Clustering analysis is applied to divide knowledge for uncertain information. III. The fuzzy association rules mining algorithm is introduced to solve the knowledge acquisition with the uncertain information in management of hazardous chemicals transportation. IV. Ontology theory is applied to implemen service mechanism of data mining of uncertain information for knowledge representation and acquisition oriented service and to build up corresponding data mining model in hazardous chemical transportation. With the above four aspects of research, knowledge representation, reductio
