Dear Heba,
depending on the sense inventory you would like the entities to, you will need to use different components. I recommend to use Wikipedia as it mostly contains entities. You could use one of the dictionaries derived from Wikipedia. The corresponding readers
are in module de.tudarmstadt.ukp.dkpro.wsd.si.dictionary
You could also use a wrapper from the module de.tudarmstadt.ukp.dkpro.wsd.wrapper-gpl. Unfortunately, there are not too many wrappers. You can use the most frequent sense with the LinkDatabaseMFADisambiguator. I
can provide you with the corresponding database if you are interested.
Best regards,
Nicolai
