A study on the possibility of cooperation among Open Data using predicate vector

Abstract

　In recent years, many administrative organizations and local governments are engaged in opening and utilizing open data but until the data utilization has not reached where the government promotes "data can be secondarily used without much manpower being machine-readable". The government has been promoting open data by formulating the "Electronic Administrative Open Data Strategy" in 2012 and operating the data catalog site "DATA.GO.JP" in 2014. Under the open data of local governments, even if they are disclosed due to the difference in data format and the lack of linkage of data, there is no active utilization yet. In this research, we propose a predicate vector method that measures the similarity of data by vectorizing item names and item values of CSV data disclosed to explore the possibility of open data of a local government. We also investigated the possibility of linkage between each data using the predicate vector method.
