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.

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).


Linked Open Data

• Public available Linked Data• Knowledge is: Organized and Accessible

Google & Linked Data

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.

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.


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?

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.

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

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
