Atomese API for Link Grammar

Atomese API for Link Grammar

This repo provides an Atomese API for Link Grammar, allowing Link Grammar dictionaries and parse results to be accessed from the AtomSpace.

Status

Version 1.0

The code here has been used in production for many years.

However, there are still some things that would be nice to have. This includes:

• Placing costs on the parse results.
• Reporting costs in dictionary lookups.

Prerequisites

The following packages must first be built and installed.

cogutil

Common OpenCog C++ utilities https://github.com/opencog/cogutil It uses exactly the same build procedure as this package. Be sure to sudo make install at the end.

atomspace

OpenCog Atomspace database and reasoning engine https://github.com/opencog/atomspace It uses exactly the same build procedure as this package. Be sure to sudo make install at the end.

Link Grammar

Natural Language Parser for English, Russian, other languages. https://www.abisource.com/projects/link-grammar/

Building LG-Atomese

Perform the following steps at the shell prompt:

    cd to project root dir
    mkdir build
    cd build
    cmake ..
    make
    sudo make install

Libraries will be built into subdirectories within build, mirroring the structure of the source directory root.

Unit tests

To build and run the unit tests, from the ./build directory enter (after building opencog as above):

    make test

At this time, there are no unit tests.

Examples

See the examples directory for examples of how to use this Atomese API to Link Grammar.
