Hello,

I downloaded Wikifier 2.0 version from the website. I ran the sample script provided and I'm getting the following error:

-bash-4.1$ sh runSimpleTest.sh 

Exception in thread "main" java.lang.UnsupportedClassVersionError: edu/illinois/cs/cogcomp/wikifier/ReferenceAssistant : Unsupported major.minor version 51.0

Could not find the main class: edu.illinois.cs.cogcomp.wikifier.ReferenceAssistant. Program will exit.

I am not a Java programmer and I am running Wikifier standalone for the first time. Kindly guide me on how I can get the software to work as I want to run it for a large set of files where running the online version is not an option.

I wasn't able to find the README file and there aren't any command line examples and parameters. Any help on this will be great!

Also, what version of the Wikipedia database is being used for the web server and the the standalone? Is there any way to update the database so it references the most up to date version of Wikipedia?

Thanks for your help!

Best,

Saloni
