I have followed the instruction given at
https://stanbol.apache.org/docs/trunk/tutorial.html to build and run the
stanbol server.
I have changed the entityhubExtraction engine to use dbpedia as Refrenced
Site from the config. Also I have downloaded the dbpedia 3.8 solr index
file.
Now, when I run text articles I am getting errors like:
Caused by: java.lang.IllegalArgumentException: The span '1' MUST BE >= the
number of matched tokens '2': Cult status[m=FULL,s=1,c=1(0.875)/2]
score=1.53125[l=0.875,t=1.75]!
For example if I run the stanbol server for the text
"Because demand for the Figaro exceeded the 20,000 vehicles built, Nissan
sold the car by lottery: winners could place orders for the car. Despite
being a JDM-only model, the Figaro is one of the most imported models of
the K10 derivatives; its popularity among numerous celebrity owners helped
it earn cult status. The K10 ceased production on 21 December 1992."
The complete error I got is :
org.apache.stanbol.enhancer.servicesapi.ChainException: Enhancement
