Recently, there has been an active study of large-scale ontology reasoning methods using big data obtained from the Web. However, when the amount of data increases, there is a problem with inference performance and processing speed decreasing. In this paper, we propose a two-step integrated system to perform inference using the Spark DataFrame in a cloud computing environment for effective inference. The first step is to perform rule inference on the OWL through a previous study inference engine. The second step, as in the previous study, performs inference on the user-defined rules through the SWRL inference engine using the Spark DataFrame. |
