The CoreNLP package is a thin Elixir client for the Stanford CoreNLP Server.
Since the Stanford offering is written in Java, the recommended integration for non-JVM languages is to stand up a CoreNLP dedicated server and hit it from a client interface. This package provides that interface for the Elixir ecosystem.
If available in Hex, the package can be installed
by adding corenlp to your list of dependencies in mix.exs:
def deps do
[{:corenlp, "~> 0.1.0"}]
endThe following are configuration settings used by this application to point to your CoreNLP server, with their defaults shown:
config :corenlp,
host: "localhost",
base_path: "/",
port: 9000,
recv_timeout: 30_000Refer to the Stanford CoreNLP Server page for detailed information regarding standing up a dedicated server (including a local instance for dev/testing).
For detailed usage information regarding options that can be passed into the various calls, please consult the Stanford CoreNLP Server documentation.
