A sentence aligner for comparable corpora

Last update: Aug 24, 2022

Overview

About

Yalign is a tool for extracting parallel sentences from comparable corpora.

Statistical Machine Translation relies on parallel corpora (eg.. europarl) for training translation models. However these corpora are limited and take time to create. Yalign is designed to automate this process by finding sentences that are close translation matches from comparable corpora. This opens up avenues for harvesting parallel corpora from sources like translated documents and the web.

Installation

Yalign requires that you install scikit-learn.

After that you can install Yalign from PyPi via pip:

sudo pip install yalign

Usage

Firstly we need to download and unpack the english to spanish model.

wget https://raw.githubusercontent.com/machinalis/yalign/develop/data/models/0.1/en-es.tar.gz
tar -xvzf en-es.tar.gz

Now we can use the yalign-align script along with the english to spanish model to align two web pages.

yalign-align en-es http://en.wikipedia.org/wiki/Antiparticle http://es.wikipedia.org/wiki/Antipart%C3%ADcula

Yalign is not limited to any one language pair. By creating your own models you can align any two languages. For more details on how to use yalign and on yalign's implementation please read the docs.

Problem with yalign-train

Hello,

I am writting to you with ask for help. It is very important for me to gain some additional data for my MT systems. You tools seems to be great but it does not work for me.

I did installation from http://yalign.readthedocs.org/en/latest/installation.html#installing-from-pypi.

With the files from tutorial all works but not with other.

I took dictionary from phrase table of mine MT system and uses OpenSubtitles 2012 corpora from OPUS project you recommended in tutorial.

For some time yalign-train works (2-3 mins) than it becomes Killed. I have no idea why. Is there any way to display what causes the error?

Really hope you can help me out.

Set WordPairScore to prefer maximum scoring pairs (rather than random).

Before, WordPairScore will take the last value of the potential translation, in the event of clashes. This didn't seem correct.

For example (using the dictionary.csv from the tutorial):

He abstained from any further comments. Se abstuvo de hacer mas comentarios.

The words 'abstained' and 'any' both can map to 'se', but 'abstained' score is 0.0138 while 'any' is 0.0015. The current code will return the smallest value because 'any' appears later in the sentence.

This commit fixes this issue, by updating the values to keep the maximum score registered within the sentence.

Running on Windows 10

Hi there,

Yalign seems to be a great alignment tool for wikitext!

I'm wondering whether can it run on Windows?

I've setted up python2 in the path, and installed all the required pakage via powershell.

What should I do next?

Many thanks to your kindly help!

Site machinalis.com is dead

wget: unable to resolve host address ‘yalign.machinalis.com’

The site machinalis.com seems to be dead. Is there an alternative location where the models can be downloaded from?

Thanks.
