Google's SyntaxNet API in Haskell

Haskell library for using Google's SyntaxNet. SyntaxNet is natural language parser including:

• Part of Speech tagger,
• syntax tree generator,
• recognition of referential expressions.

This API allows:

1. Reading saved SyntaxNet parse tree, POS, or reference assignment from file.
2. Easy manipulation of the parse trees with extra information (given by POS and/or reference assignment.)

Documentation

Documentation will put into docs folder.

Tests

Examples of parsed SyntaxNet inputs are attached.

There are following files there for each test:

• .txt file contains the input
• .cnll file contains the SyntaxNet output from run.sh script (parsed by the library)
• .tree file contains the SyntaxNet output from demo.sh script (if present)

Usage

1) stack repl
2) :load src/NLP/SyntaxNet/SyntaxNet.hs 
3) > tr <- readParseTree "test/examples/test1.tree"
4) > drawTree' $ fromJust $ tr
for Testing.
