2. What is value of information?
Hideaki Takeda / National Institute of Informatics

3. It is a silly question.
Information has its own value.
That’s it?
Probably no…
Hideaki Takeda / National Institute of Informatics

4. Value of information is laid in
lifecycle of information
Hideaki Takeda / National Institute of Informatics

5. Lifecycle of Information
Share
Collect Publish
Use
&
Create
Hideaki Takeda / National Institute of Informatics

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

7. Archiving in Lifecycle of Information

8. Archiving in Lifecycle of Information
 Just a part of life cycle
 Lack of SHARING!

9. How can we make information
open and shared?

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.

11. LOD Cloud
(Linking Open Data)
Open and Share!

12. Linked Data and MLA
 Library
 Many national libraries open bibliographic and authority data as
LOD
 British Library
 Library of Congress
 National Diet Library
…
 Museum
 Ongoing now
 Europeana
 W3C (World Wide Web Consortium) Incubator Group Report on
Library Linked Data

15. LODAC Project
 Open Social Semantic Web Platform for Academic Resources
 Providing platforms for Linked Data
 Practicing data accumulation and publishing
 Interested Areas
 Museum information
 Geographical information, especially geographical names
 Local information
 Biological information (species information)
 …

16. LODAC-Museum (tentative)
 The state-of-the-art of museum information in
 Distributed
 Self-maintained
 Isolated
 Opaque
 Self-designed
 Messy
 Aggregating and associating museum information
 LODAC-Museum (tentative)

18. Integration Policy
 How to integrate data from different sources
 sharing of responsibility
 Each source is responsible for its data
 Identifying IDs for data and managing data with the IDs
 LODAC is only responsible for integration
 Assigning original IDs and associating other IDs to them

27. Applications
New values by association
 Associating information among
Museum LOD
museum information
 Aggregation by subject
Geo LOD  Ex. Author – work – local
museum – local information
 Aggregation by location
Local 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

39. Summary
 Value of information is laid on lifecycle of information
 Collect – User & Create – Publish(Open) – Share – Collect – …
 Open & Share is needed!
 Linked Open Data (LOD) is a way to open and share information
 LOD can add new values for information
 LOD can change research style
