Related Work

Several projects exploit semantic information.I Large portions of BBC website are run on Semantic Web

technologies..

Related projects:

Is it really necessairy?

In our opinion, yes!I Because

1. it’s another brick in the wall of the so called “smart web"2. it can potentially assist in the prevention of fire break out,

pollution . . .3. it could be used in other scientific or commercial fields

(tourism, agriculture, weather forecasting. . . )I “. . . there is a continuous draught during the past years.

D@mn, we ’ve got to find new species to grow. . . ", author’suncle, farmer!!!

Future Work and Challenges

I It’s still work in progress.I Demos for future results.I Keep an eye on the web for new (better?) data sources.I Integration with existing semantic frameworks (Open

Linked Data?).
