NERDF: Named Entities Recognition (NER) + RDF
=============================================
This is a small demo to perform Named Entities Recognition driven by a
gazeteer built from an RDF dataset.
If you want to try it, here is how you can checkout and compile it:
cd /tmp
git clone git://github.com/castagna/nerdf.git
cd /tmp/nerdf
mvn package
Load some data (for example the data.nt file included in NERDF) into
TDB and point NERDF to it (via standard <init-param> in
src/main/webapp/WEB-INFO/web.xml, by default NERDF looks into
/tmp/nerdf/target/tdb):
mkdir -p /tmp/nerdf/target/tdb
tdbloader --loc /tmp/nerdf/target/tdb data.nt
Run the demo:
mvn jetty:run
firefox http://127.0.0.1:8080/index.html
This is just a small, quick and dirty, proof of concept (and the name
isn't great on purpose), there are many (and much better) similar services
out there, for example:
- http://www.opencalais.com/
- http://www.zemanta.com/
- http://tagme.di.unipi.it/
- http://dbpedia.org/spotlight
- ...
But, they don't give you the source code and they do not work with *your*
data. ;-)
