When government data is, in principle, made open to the public, the volume of data is incredible. It’s not just numerical data; it also includes written information like official documents, reports, and supporting materials attached to those reports. But when most citizens utilize that information, they don’t know what government agency or entity it’s from. And it’s hard to correlate the data simply by doing a full document search. So many countries are trying to use Knowledge Graph or Web Ontology to correlate data from different sources. But to set that up, all government entities have to coordinate their efforts, and input data using the same categories. In Taiwan, that’s extremely difficult.
