How does your technology distinguish facts from lies?

Well it doesn’t. Linked Data technology can give you better means to decide whether to accept a claim as fact or not by linking it to supportive evidence or rebuttals. By making assertions more precise they are the better object of scrutiny, by linking them to a network of knowledge one can see what acceptance of a claim implies.

Where do I find Linked Data?

Several government agencies have started providing data as Linked Data. DBpedia.org exposes the contents of Wikipedia as Linked Data. Wikidata.org is a free and open knowledge base that can be read and edited by both humans and machines, Wikidata exposes all its data as Linked Data and allows querying with SPARQL.

What’s the difference between Linked Data and traditional Web Sites?

The traditional Web is document oriented. Only documents can be interlinked using traditional Web technologies. Linked Data allows to expose the meaning of individual bits of data and interlink them together. For example a weather forecast site on the traditional web only contains information about how the information should be displayed, with linked data it also contains the machine readable information that a specified value is the expected temperature at a specified date in specified place. The site might link to a geographic authority to allow users and applications to access more information about the place. By having machine readable data applications can do more for us, for example give as a list of places  that are sunny tomorrow and that we can reach by train in less than an hour.

Why would public agencies publish link data?

Publishing Linked Governmental Data can reduce cost, maximize the impact and also help immunizing the public against fake news. It reduces costs as less freedom of information requests have to be answered and because it reduces the need to maintain specific applications that give access to their data. With the data openly available as Linked Data proprietary interfaces to the data become obsolete, application developers can build applications that directly access the data. The data can be used as reference in other linked data such as on Wikipedia maximizing the visibility and the impact of the data. Journalist can reference to the governmental data helping to distinguish facts from fake news and also showing the relevance of the work and data of the publishing agency.

What benefits do libraries have from publishing Linked Data?

A crucial purpose of libraries and of library catalogs it to make their bibliographic items findable. Unlike a traditional library catalog a catalog published as linked data will also allow searching using data from other sources, for example one could search for all books published by authors born in a certain town, as the library catalog does not itself contain the place of birth of the authors such a query would also access data from another source such as Wikidata.
Another advantage is that bibliographies can directly reference to the item available in the library.
