Linguistica 5 is a Python library for unsupervised learning of linguistic structure.

Full documentation: http://linguistica-uchicago.github.io/lxa5/

Apart from being a Python library, Linguistica 5 provides two additional interfaces: (i) graphical user interface; (ii) command line interface.

Work by Jackson Lee and John Goldsmith

Please note that this code (Linguistica 5) is not John Goldsmith's development code, which can be found on his GitHub repository. The most recent release of John Goldsmith's code is Linguistica 4; see Linguistica at UChicago.

Note: If you are a developer of the Linguistica project group, you should ignore this section and set up your environment by following these notes.

Linguistica 5 is available through pip:

$ pip install linguistica

Linguistica 5 works with Python 2.7 and 3.4+.

To use the graphical user interface, only Python 3 is supported. In addition, PyQt5 and SIP are required. PyQt5 is readily available from pip:

$ pip install PyQt5

At the time of writing (April 2017), SIP is best downloaded and installed from its source. (SIP is available through pip, but it does not include the C/C++ code generator for PyQt5.)

To use Linguistica 5 as a Python library, simply import linguistica in your Python programs:

import linguistica as lxa

Quick library demo here.

To launch the Linguistica 5 graphical user interface (with SIP and PyQt5 installed):

$ linguistica gui

To launch the Linguistica 5 command line interface:

$ linguistica cli
