pyhfst 1.0.1

A pure Python implementation of HFST for using HFST optimized lookup transducers (with or without weights)

Pyhfst

Pyhfst is a pure Python implementation of HFST. The library makes it possible to use HFST optimized lookup FSTs without any C dependencies. Both weighted and unweighted FSTs are supported.

The library will run on all operting systems that support Python 3.

Installation

pip install pyhfst

Usage

import pyhfst

input_stream = pyhfst.HfstInputStream("./analyser")
tr = input_stream.read()
print(tr.lookup("voi"))

>> [['voida+V+Act+Ind+Prs+Sg3', 0.0], ['voida+V+Act+Ind+Prs+ConNeg', 0.0], ['voida+V+Act+Ind+Prt+Sg3', 0.0], ['voida+V+Act+Imprt+Prs+ConNeg+Sg2', 0.0], ['voida+V+Act+Imprt+Sg2', 0.0], ['voi+N+Sg+Nom', 0.0], ['voi+Pcle', 0.0], ['voi+Interj', 0.0]]
