FST Lookup

Implements lookup for FOMA format finite state transducers.

Supports Python 3.5 and up.

Usage

Import the library, and load an FST from a file:

>>> from fst_lookup import FST
>>> fst = FST.from_file('eat.fomabin')

Analysis

To analyze a form (take a word form, and get its linguistic analyzes) call the analyze() function:

def analyze(self, surface_form: str) -> Iterator[Analysis]

This will yield all possible linguistic analyses produced by the FST.

An analysis is a tuple of strings. The strings are either linguistic tags, or the lemma (base form of the word).

FST.analyze() is a generator, so you must call list() to get a list.

>>> list(sorted(fst.analyze('eats')))
[('eat', '+N', '+Mass'),
 ('eat', '+V', '+3P', '+Sg')]

Generate

To generate a form (take a linguistic analysis, and get its concrete word forms), call the generate() function:

def generate(self, analysis: str) -> Iterator[str]

FST.generate() is a Python generator, so you must call list() to get a list.

>>> list(fst.generate('eat+V+Past')))
['ate']
