Chalk is a library for natural language processing (NLP).

The latest stable version is 1.2.0. This version is essentially the code based that was in breeze.process, with "breeze" renamed to "chalk", plus some simple Scala utilities that were in Chalk already.

See the CHANGELOG for changes in previous versions.

In SBT:

libraryDependencies += "org.scalanlp" % "chalk" % "1.2.0"

In Maven:

<dependency>
   <groupId>org.scalanlp</groupId>
   <artifactId>chalk</artifactId>
   <version>1.2.0</version>
</dependency>

• Version 1.6 of the Java 2 SDK (http:https://java.sun.com)

Set 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.

Chalk uses SBT (Simple Build Tool) with a standard directory structure. To build Chalk, type (in the CHALK_DIR directory):

$ ./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:

$ ./build

To make sure all the tests pass, do:

$ ./build test

Documentation for SBT is at http:https://www.scala-sbt.org/
