Hi Rupert, Thanks again for your suggestions. I cloned and build the stanbol-stanfordnlp project above and executed the run command [1] as below in a separate directory. But the server startup doesn't complete..it hangs at a point with the log entry : "Reading TokensRegex rules from edu/stanford/nlp/models/sutime/english.holidays.sutime.txt"
Any ideas? Can I edit the configurations to skip the above TokenRegex rules and start the server?
