  6. 6. Lifecycle of Information Information can be created only based on existing information  No information can be created out of nothing Share  Collect – Use & Create Value of information is how much it is used  No value for information without use  Use & Create – Publish Collect Publish Accumulation of information is the wealth of society  Distribution of information is the health of society  Publish – Share -- Collect Use & Create Hideaki Takeda / National Institute of Informatics

  10. 10. Linked Data Linked Data is “Web of Data” Standard format  Data published as RDF Linkable to each other!  Can refer from outside Four conditions for Linked Data  Use URIs as names for things  Use HTTP URIs (http://..) so that people can look up those names.  When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)  Include links to other URIs. so that they can discover more things.Linked Data, TBL, http://www.w3.org/DesignIssues/LinkedData.html Hideaki Takeda / National Institute of Informatics

  27. 27. Applications New values by association  Associating information amongMuseum LOD museum information  Aggregation by subject Geo LOD  Ex. Author – work – local museum – local information  Aggregation by locationLocal info. LOD  Ex. Local name – geographic Scientific paper DB information – old name – old literature  Associating information from different communities  Ex. Wikipedia - articles - data  Association with collective intelligence  Integration with user generated contents 27 Hideaki Takeda / National Institute of Informatics
