Stanford CoreNLP

The classpath must include all of the CoreNLP dependencies. The memory requirements of the server are the same as that of CoreNLP, though it will grow as you load more models (e.g., memory increases if you load both the PCFG and Shift-Reduce constituency parser models). A safe minimum is 4gb; 8gb is recommended if you can spare it. The server can be stopped programmatically by making a call to the /shutdown endpoint with an appropriate shutdown key. This key is saved to the file /tmp/corenlp.shutdown
