NOTE: This project is currently dormant with no current prospect for further development. Suggestion: check out OpenNLP or StanfordNLP for the JVM or spaCy for Python. (If anyone would like to do something like spaCy for Scala, that would be fantastic.)
Chalk is a library for natural language processing (NLP).
The latest stable version is 1.3.2. Changes from the previous release include:

Configuring your environment variables
JAVA_HOME to match the top level directory containing the Java installation you want to use. If you want to be able to use the
chalk command line executable, set
CHALK_DIR to where you put Chalk, and then add the directory
CHALK_DIR/bin to your path.
Building the system from source
Chalk uses SBT (Simple Build Tool) with a standard directory structure. To build Chalk, type (in the
$ ./build update compile
This will compile the source files and put them in
./target/classes. If this is your first time running it, you will see messages about Scala being downloaded -- this is fine and expected. Once that is over, the Chalk code will be compiled.
To try out other build targets, do:
To make sure all the tests pass, do:
$ ./build test
Documentation for SBT is at http://www.scala-sbt.org/
