? Intro

Lingtrain Studio is the ML based app for accurate texts alignment on different languages.

  • Extracts parallel corpora from two texts.
  • Makes the formatted parallel book from it with sentence highlightning.

? Models

Automated alignment process relies on the sentence embeddings models. Embeddings are multidimensional vectors of a special kind which are used to calculate a distance between the sentences. You can also plug your own model using the interface described in models directory. Supported languages list depend on the selected backend model.

  • distiluse-base-multilingual-cased-v2
    • more reliable and fast
    • moderate weights size — 500MB
    • supports 50+ languages
    • full list of supported languages can be found in this paper
  • LaBSE (Language-agnostic BERT Sentence Embedding)
    • can be used for rare languages
    • pretty heavy weights — 1.8GB
    • supports 100+ languages
    • full list of supported languages can be found here

? Running on local machine

You can run the application on your computer using docker.

  1. Make sure that docker is installed by typing the docker version command in your console.

  2. Images configured to run locally are available on Docker Hub.

  3. Run the following commads in your console:

    • docker pull lingtrain/studio:v7.2
    • docker run -v C:\app\data:/app/data -v C:\app\img:/app/static/img -p 80:80 lingtrain/studio:v7.2
  4. App will be available in your browser on the localhost address.

  5. If you need to run the container on another port (e.g. localhost:8081):

    • Change the API_URL parameter in config.js
    • Rebuild the docker container
    • Start it with changed -p parameter (e.g. -p 8081:80)

? Running in development mode

Clone this repo on your machine.


Flask/uwsgi backend REST API service. It’s pretty simple and contains all the alignment logic.

cd /be python


SPA. Vue + vuex + vuetify. UI for managing alignment process using BE and a tool for translators to edit processing documents.

cd /fe


npm install

Compile and run with hot-reloads for development

npm run serve
