Bills of Standard Manufacturing Services (BOSS) Construction Based on focused Crawler

As an advanced manufacturing model, cloud manufacturing(CMfg) has made great progress in recent years. The concept of CMfg has been introduced to many industries. With the growing diversity of products, the complexity of cloud manufacturing service encapsulation is also increasing. To solve the problem of product-oriented service standardized encapsulation, the Bills of Standard Manufacturing Service(BOSS) has been proposed. It can systematically solve the problem of deployment, registration and management of cloud manufacturing services in the whole product life cycle. In this paper, based on the service ontology model, we proposed an automatic perfecting service information method of BOSS using the focused crawler technology. Combined with the case study, we verified the feasibility and effectiveness of this method. Finally, the application framework of BOSS in the cloud manufacturing system is further discussed.
