RDF Data Management and SPARQL Query for Patent Information

Resource Description Framework (RDF) is a general framework to model and describe information within the Web. To cope with the growing size of RDF information, an efficient management and query system is required. SPARQL Protocol and RDF Query Language (SPARQL) is a well-known RDF query language to retrieve and manipulate data stored in RDF format. This paper applies these techniques to manage patent information systematically . To achieve this, the structure of patent information is first defined by analyzing several patent information, especially KIPRIS. And then, the RDF schema is designed to represent the structure of patent information. A prototype system was developed and tested to show RDF and SPARQL can be consistently applied to manage patent information.
