Semantic Web and ontology play an important role in various research fields today, but are rarely used in the materials science domain. In this paper we propose an approach to find a mapping method from metal materials database to an ontology. The proposed method refers to the latest W3C standard DM and R2RML. The goal of the mapping system is to transform Relational Database (RDB) to the Resource...
A new sensitive rule hiding algorithm, including two processes of weak association transaction adding and strong association transaction removing, is presented based on the devotion degree of transactions to the discovered association rules. The approach and algorithm are stated in detail aiming to hide simple rules,including two types of single rule and composed rule.Four item modification methods...
With the development of the Semantic Web, ontology is playing an increasingly important role in many research areas such as semantic interoperability and knowledge base. However, building ontology manually is time-consuming and error-prone. In such a case, this paper proposes a method of building domain-specific OWL ontology from relational database automatically. This method establishes three mapping...
