systran-align 3.1.0

Alignment tool based on fast_align

systran-align

systran-align is a small alignment tool that is based on https://github.com/clab/fast_align.

Installation

pip install systran-align

Usage

import systran_align

Generating alignment probabilities

systran_align.generate_alignment_probabilities(
    input_path: str,
    forward_probs_path: str,
    backward_probs_path: str,
    verbose=False,
    iterations=5,
    favor_diagonal=False,
    beam_threshold=-4,
    diagonal_tension=4,
    optimize_tension=False,
    variational_bayes=False,
    alpha=0.01,
    no_null_word=False,
    prob_align_null=0.08,
    thread_buffer_size=10000)

Computing alignments

aligner = systran_align.Aligner(
    forward_probs_path: str,
    backward_probs_path: str)

alignments, forward_log_prob, backward_log_prob = aligner.align(
    source: list,
    target: list)
