dbpedia spotlight dataset

Question

In continuation of dbpedia spotlight dataset, I followed the instructions for updating my dataset but got the following error:

INFO 2012-06-19 11:58:04,300 main [MergedOccurrencesContextSearcher] - Using index at: org.apache.lucene.store.MMapDirectory@/home/user_name/new/spotlight/index lockFactory=org.apache.lucene.store.NativeFSLockFactory@671381e7

I had been able to successfully use the spotter dictionary but couldn't use the index files.

Can you please help me?

Answer 1

Hard to help you without sufficient information. The message complains that a file is not there. Is the file there? Is the directory there?

Please paste the result of the command ls -lah /home/user_name/new/spotlight/index
