What is Linked Data?

• Give every data item a URIhttp://example.com/presentations/fsasaki-xmlprague2015

• Linked data statements: use URIs tointerrelate data – like links between Web pages

http://example.com/presentations/fsasaki-xmlprague2015

http://example.com/locationOfEvent

http://example.com/cities/prague

Linked data format: RDF

• One RDF storage syntax: turtle (here abbreviated)

The linked data cloud – billions of interlinked triples from interlinked data sets

Sasaki – XML Prague 2015 preconference

Linguistic Linked Data (LLD)• Representing linguistic resources as linked data

– Lexica, thesauri, corpora, …

LLD: topic of the LIDER project http://lider-project.eu

“Linked Data as an enabler of cross-media and multilingual content analytics for enterprises across Europe”

• One work item: Getting feedback from communities on benefits and challenges of (linguistic) linked data

5

Sasaki – XML Prague 2015 preconference

XML Prague last year:• LIDER session on XML, Semantic Web and

Content Analytics

• Outcome: feedback from the XML community – What is needed to deploy linked data and XML together in applications?

6

<myDoc>...</myDoc>?

Sasaki – XML Prague 2015 preconference

Feedback from last year (examples)

• Potential users of linked data in the XML community, usability of linked data tools, integration into (XML) content workflows, relation between data formats (XML – RDF), domain and language of (linguistic) linked data, …

• More in W3C LD4LT group wiki documenting the XML Prague session

PRACTICAL PART – DEMO: DEPLOYING LINKED DATA IN OXYGEN

8

Sasaki – XML Prague 2015 preconference

Scenario and user types

• Author wants to write a travel guide

• Content architect with knowledge on linked data sets: setup of oXygenxml editor

– On the fly enrichment of content with linked data sources

– Author can choose subset of sources

– Author uses WYSIWYG author mode

– Demo video: http://youtu.be/2dZQ2BWnGDc

Current state: deployment of linked data requires XML + RDF coding

10

• XSLT Stylesheet fetching linked data from the Web

• Encompasses linked data SPARQL query

Sasaki – XML Prague 2015 preconference

Future via FREME project

11

• Easy to use APIs and GUIs, among others for working with (linguistic) linked data

• Linked data tooling integration in the background• Content architect will benefit from

simple interfaces• More soon at http://www.freme-project.eu

Want to know more?

• Join the LD4LT group

• https://www.w3.org/community/ld4lt/

• Provide feedback

– Your needs on linguistic linked data sets

– Your visions on LLD applications

– Your input on how easy to use interfaces (both APIs and GUIs) should look likein your usage scenario

12

Sasaki – XML Prague 2015 preconference

And now: it‘s time for your feedback

• What type of data (domain, language, format, …) is relevant for your applications?

• What type of software or graphical interfaces do you need?

• And: what application do you have in mind?
