link-parser-js

Emscripten port of link-parser, the CLI for the CMU Link Grammar natural language parser

Motivation

I wanted a version [of link-parser] that is more portable, so it can be easily installed and run in any environment with node.js, including node.js cloud hosting platforms and a variety of Unix/Windows developer machines.

Usage

Same as the original link-parser program. For details, run link-parser-js --help and or see the official documentation.

Note that loading custom dictionaries or input files from the filesystem is not currently supported. Pull Requests welcome.

Example:

> echo This is a sentence. | link-parser-js en -constituents=1
constituents set to 1
link-grammar: Info: Dictionary found at ./data/en/4.0.dict
Debug: Dictionary "en/4.0.dict": Locale "en_US.UTF-8" unknown
link-grammar: Info: Dictionary 'en/4.0.dict': No locale definition - "C.UTF-8" will be used.
link-grammar: Info: Dictionary version 5.8.0, locale C.UTF-8
link-grammar: Info: Library version link-grammar-5.8.0. Enter "!help" for help.

Press RETURN for the next linkage.
linkparser> Bye.

In addition to being used in the console (as in the above example), this program is intended to be used programatically with node.js's child_process module.
