Although value of ontologies is widely admitted in web-based information management, acquisition of ontologies is still the bottleneck in developing applications based on them. Rapid acquisition of high-quality software component attribute ontology (SCAO) is desired in some infrastructural platforms that intend to facilitate weaving Web-based information systems based on software component. After analyzing existing methodologies, we advance a new methodology for acquiring SCAO. The purpose of this methodology is that both rapid acquiring ontologies and quality control of ontologies can be achieved. The ontology acquisition process, the algorithm of metaproperty collision inspection, and a tool based on this algorithm are discussed in our methodology. The process of SCAO acquisition is hereby described in detail, which indicates that our methodology is practical to rapidly acquire high-quality ontologies.
