3. Background
The Web of Linked Data grows rapidly and
contains data from a wide range of different
domains,
including
life
science
data,
geographic data, government data, library and
media data, as well as cross-domain data sets
such as DBpedia or Freebase.

4. Background
According to the Linked Open Data Cloud
Diagram (LODCD), there are 295 data sets
catalogued and classified under Linked Open
Data format (public available data).

9. Problem?
Linked Data applications that want to consume data from
this global data space face the challenges that:
• Data sources use a wide range of different RDF
vocabularies to represent data about the same type of
entity.
• The same real-world entity, for instance a person or a
place, is identified with different URIs within different
data sources.
• Data about the same real-world entity coming from
different sources may contain conflicting value.

14. Knowledge Transfer
Dr. Spence Silver, a 3M scientist, is busily
researching adhesives in the laboratory. In the
process, he discovers something peculiar: an
adhesive that sticks lightly to surfaces but does
not tightly bond to them.

15. Knowledge Transfer
While singing in his church choir,
Art Fry, another 3M scientist, tires
of losing his place in the hymnal.
He dreams of a bookmark that's
lightly
adhesive.
Then
he
remembers Silver's adhesive, and
his dream begins to become real.
What would happen if knowledge could be
transferred to other domains?

16. Conclusions
• Linked Data as an alternative to keep the
information structured and organized through
the Web, is the present, not the future.
• Linked Open Data is an efficient way to
increase knowledge sharing through the
Web.
• LiDIA aims to achieve knowledge transfer
and integration of multiple data sources.

17. Future Work
Use of user interface design patterns, and other
technologies available in the human-computer
interaction context in order to improve the user
experience:
• Natural language processing
• Speech recognition

18. Future Work
Achieve the integration for multiple domains:
• Process queries and provide them with
context, regardless of the domain of
knowledge in which the user makes the
search in order to get better results
