This XML Prague 2015 Pre-conference presentations shows practical usage of linked data sources. These sources can help to: enrich content with entities, add link to external data sources, use the enriched content in question answering, machine translation or other scenarios. The aim is to show the practical application of linked data sources in XML tooling. The presentation is an update and provides outcomes of the related session held at XML Prague 2014.

What is Linked Data?
• Give every data item a URI
http://example.com/presentations/fsasaki-xmlprague2015
• Linked data statements: use URIs to
interrelate data – like links between Web pages

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

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?

7. 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

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
11. 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 like
in your usage scenario

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?
