An automatic ontology building method with case-base in semantic SOA integrated system

While ontology is critical to realize semantics, many defects exist in its building methods, especially conflicts between building cost and ontology quality. Specific to this problem, the paper brings forward an automatic ontology building method grounded on case-base. That is, to build domain ontology automatically with field concepts and relations extracted from case-base which records a plenty of users´ domain knowledge and experience. Firstly, the paper provides an in-depth study on theoretical analysis, which discusses its feasibility and effectiveness. Then, a system architecture and workflow are designed to adapt to the method. The last but not the least, combined with field characteristics of complex products´ manufacturing process, algorithm and implementation concerning key technologies are comprehensively elaborated.
