W3C Incubator Group: Library Linked Data

Libraries...

build communities

provide users with services

New ways to do this on the Web:

user-contributed content

crowd curation

Making Social Data in Librariesmore important

Social Uses of Library Linked Data

W3C LLD XG Social Uses cluster

http://bit.ly/lld-social-cluster

Use Cases:

• Social Annotation

• Peer-to-Peer Book Swapping

• Social Recommendations

Social Annotation

[Social] Annotation

Increasingly:

1.created digitally

2.published online

3.shared

Annotation data can have ....

Different levels of granularity:

• whole book/work

• chapters or sections

• pages

• paragraphs or sentences

• words

Different contents:

• quote

• commentary

• position only (bookmarks and linemarkers)

Linked Data can help

• Identify materials to annotate

• Point to fragments and sections

• Publish annotations

• Aggregate annotations

Book swapping @ IRL

Challenges of Book Swapping

information problem: who has what?

Paper books:

- have to meet in person or pay shipping

E-book swapping:

- restricted number of times books can be lent

- restricted period books can be lent for

- paying for service providers [some services]

Metadata for Bookswapping

• Rights expression: Lendable?o can lend X times, has been lent Y timeso conditions for lending a book (will ship, meet, ...)

• Holdingso listing of the books I have

• Wishlistso listing of the books I want to read (but not buy)o topics, genres I am interested in

• Friendso who can I borrow from?

How Linked Data can help

• Integrate wishlists across services

• Identify friends of friends

• Express rights/permissions

Social Recommendations

Valdis Krebshttp://orgnet.com

Interactions -> Recommendations

Interaction creates a trail of information

that can be used to make recommendations.

Types of Interactions

• Lending (circulation data), buying, reading

• Viewing pages & items

• Adding to favorites

• Recommending to others

• Tagging

• Adding reviews & annotations

Recommendations in libraries

• Alternatives to checked-out movies & books

• Books with an opposing perspective

• Similar authors, journal articles, etc.

• ...

Based on:

• What other users have done: interactions

• Available [linked] data (authority data, etc.)

• Social network connections

Linked Data can help

• Transport data between systems

o Increase volume & diversity of data

• Share public data sets seamlessly

o Decentralized, distributed

• Query over private data (SPARQL)

o Anonymization

• Share recommendations as linked data, too!

Imagine: Small Demons as Linked Open Data

What could / would you do with that?

What could / would you do with that?

If Amazon recommendations are enough to build networks of books, what could people build with info from, e.g., Small Demons?

Social networks of books, places, things, ...

Opening up the data =>

=> Unexpected uses

Imagine: Small Demons as Linked Open Data

Summary

• Social Annotation

• Peer-to-Peer Book Swapping

• Social Recommendations

We need more Open Data!

• Power of combining Social and Linked Data

• Creating interest in this combination

o Opportunitieso Message for getting these use cases &

other social use cases implemented

Let's make it happen!

• Discuss what's needed to implement these (and other) use cases

• Collect informationo re existing work and new ideaso add to / edit: http://tinyurl.com/elag-lld

• Build applications and do stuff with the data!

Thank you!
