This set presents the concept of Linguistic Linked Licensed Data (known as 3LD) and the LIDER project http://www.lider-project.eu/. The project’s mission is to provide the basis for the creation of a Linguistic Linked Data cloud that can support content analytics tasks of unstructured multilingual cross-media content. By achieving this goal, LIDER will impact on the ease and efficiency with which Linguistic Linked Data will be exploited in content analytics processes.

Heterogeneity of Linguistic Resources
• Ecosystem of
– Open and Close resources
– Complementary resources
• Lexicon
• Corpora
• Dictionaries
• ….
– Heterogeneous formats
• E.g, for Lexicons: Lexinfo, LMF, LIR, Lemon, …
– Language Resources available on the web
• Meta-share, ELDA, ELRA, Clarin, FLaReNet, MultiJEDI,

4. 20/03/2014 4Asun Gómez-Pérez
Limitations when exploiting LRs
• The process of finding and
integrating LR in third party
applications is manual and time
consuming
• LR metadata
– cannot be queried using a common
language (e.g. SPARQL)
• LR content
– is available in heterogeneous formats
– LR content is not linked with other
linguistic content
Language resources and technologies supported are still far
from being Free, Open and Interoperable

LD as a possible solution
• Agree on 21st century
vocabularies for describing
resource metadata and content
• Unified and standardized
language for describing resources
( RDF(S))
• Unified and standardized query
language (SPARQL)
• Standardized non-propietary APIs
• Links to other resources

Linked Open Data and Language
1. LOD is increasingly
multilingual
2. LOD interconnects
resources
– In many domains
– in many languages
How many Linguistic Resources are exposed in RDF?

16. 20/03/2014 16Asun Gómez-Pérez
Linked Data and Language Resources
Linguistic LOD (LLOD)
 Subset of LOD
 Linguistic domain
 Open License
 Resources in RDF
 Interconnected with other LD
resources
• Long term experience
• Huge amount of resources
• Maturity
• Curation
• Legal liability

What is 3LD?
3LD
Linguistic Linked Licensed Data
Language resources
such as:
- Lexica
- Corpora
- Dictionaries ..
NIF
NLP Interchange Format
Using RDF and
standard data
models
(vocabularies):
- Lexica
- Corpora
ODRL
Open Digital Rights Language
Published along with
a machine-readable
license.

20. 20/03/2014 20Asun Gómez-Pérez
Challenge
• Which extensions to the LOD are needed to support a new
generation of large-scale content analytics applications that will
overcome language barriers.
– Expose Linguistic Resources in LD format with license information
• Metadata
• Content
– Guidelines for Linguistic Linked Licensed Data (3LD)
– Specification of a new generation of 3LD aware NLP services
• Requirements:
– Keep track of the License information
– Keep track of the Provenance of the resource
– Keep track of the use of the resource
