| Abstract(in English) | Despite recent open data initiatives in many countries, not a few of those countries provide the data in non-machine-readable formats like an image format rather than in a machine-readable electronic format, thereby restricting their usability. An approach is described for converting legacy statistical data in an image format into a machine-readable and reusable format by using crowdsourcing. Requesting crowd workers not only to extract tables from graph images but also to reconstruct them in spreadsheets can reduce the number of errors compared to simple extraction and, at the same time, produces structures including attribute names and values as properties of the reconstructed graph objects. Experimental results using the White Paper on Tourism published by the Japan Tourism Agency demonstrated that the proposed approach is effective. |
