Hi Manish I had the same error once. In that case the error was originating from some uncommon UTF8 chars, where basically two chars at the same position where creating a single character in the text.

Can you try if you can reproduce the error on "http://dev.iks-project.eu:8081/enhancer"; or "http://dev.iks-project.eu:8081/enhancer/chain/dbpedia-noun-linking";? > 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]! > at > org.apache.stanbol.enhancer.engines.entitylinking.impl.LabelMatch.<init>(LabelMatch.java:96) > at > org.apache.stanbol.enhancer.engines.entitylinking.impl.EntityLinker.matchLabel(EntityLinker.java:762) This exception is basically a "safeguard" that wars for an unexpected state in the EntityLinking process. One could also just write a warning to the log, but then it would be much less likely to discover such issues. The warning suggests that the section "cult status" is the reason for the exception. As the matching label "Cult status" is a FULL match, but the matching score is lower than 1 (0.875) my assumption is that the section "... earn cult status. The ..." does indeed contain some special UTF8 characters because otherwise I one would expect an exact match with a score of 1.0. Can you please check the original text for such chars? I will have a look at the exception. Maybe I should catch those exceptions and write a detailed summary (including the source text, tokens, pos tags ...) to the logs instead.
