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 "Open data can be secondarily used without much manpower being machine-readable". 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. In addition, using the predicate vector method, we experimented on the possibility of cooperation between each data, and compared the degree of cooperation of each item name and the degree of cooperation of each column data among open data. As a result, it was shown that open data with a high degree of cooperation calculated from column data has a high degree of similarity of a specific column, making it easy to establish data cooperation.
