A Python library to conjugate verbs in French, English, Spanish, Italian, Portuguese and Romanian (more soon) using Machine Learning techniques.
Any verb in one of the supported language can be conjugated, as the module contains a Machine Learning model of how the verbs behave.
Even completely new or made-up verbs can be successfully conjugated in this manner.
The supplied pre-trained models are composed of:
  • a binary feature extractor,
  • a feature selector using Linear Support Vector Classification,
  • a classifier using Stochastic Gradient Descent.
MLConjug3 uses scikit-learn to implement the Machine Learning algorithms.
Users of the library can use any compatible classifiers from scikit-learn to modify and retrain the models.
The training data for the french model is based on Verbiste https://perso.b2b2c.ca/~sarrazip/dev/verbiste.html .
The training data for English, Spanish, Italian, Portuguese and Romanian was generated using unsupervised learning techniques using the French model as a model to query during the training.

Warning

MLCONJUG3 now only supports Python 3.x as Python 2.x has been deprecated in 2020.

Usage

Note

The default language is French. When called without specifying a language, the library will try to conjugate the verb in French.

To use MLConjug3 from the command line:

$ mlconjug3 manger

$ mlconjug3 bring -l en

$ mlconjug3 gallofar --language es

$ mlconjug3 -o, --output (Path of the filename for storing the conjugation tables.)

$ mlconjug3 -s, --subject (The subject format type for the conjugated forms). The
                   values can be 'abbrev' or 'pronoun'. The default value
                   is 'abbrev'.

    • Implemented a new vectrorizer extracting more meaningful features.
    • As a result the performance of the models has gone through the roof in all languages.
    • Recall and Precision are intesimally close to 100 %. English being the anly to achieve a perfect score at both Recall and Precision.
  • Major API changes:
    • I removed the class EndingCustomVectorizer and refactored it’s functionnality in a top level function called extract_verb_features()
    • The provided new improved model are now being zip compressed before release because the feature space has so much grown that their size made them impractical to distribute with the package.
    • Renamed “Model.model” to “Model.pipeline”
    • Renamed “DataSet.liste_verbes” and “DataSet.liste_templates” to “DataSet.verbs_list” and “DataSet.templates_list” respectively. (Pardon my french ;-) )
    • Added the attributes “predicted” and “confidence_score” to the class Verb.
    • The whole package have been typed check. I will soon add mlconjug3’s type stubs to typeshed.

2.1.11 (2018-06-21)

  • Updated all provided pre-trained prediction models
    • The French Conjugator has accuracy of about 99.94% in predicting the correct conjugation class of a French verb. This is the baseline as i have been working on it for some time now.
    • The English Conjugator has accuracy of about 99.78% in predicting the correct conjugation class of an English verb. This is one of the biggest improvement since version 2.0.0
    • The Spanish Conjugator has accuracy of about 99.65% in predicting the correct conjugation class of a Spanish verb. It has also seen a sizable improvement since version 2.0.0
    • The Romanian Conjugator has accuracy of about 99.06% in predicting the correct conjugation class of a Romanian verb.This is by far the bigger gain. I modified the vectorizer to better take into account the morphological features or romanian verbs. (the previous score was about 86%, so it wil be nice for our romanian friends to have a trusted conjugator)
    • The Portuguese Conjugator has accuracy of about 96.73% in predicting the correct conjugation class of a Portuguese verb.
    • The Italian Conjugator has accuracy of about 94.05% in predicting the correct conjugation class of a Italian verb.

2.1.9 (2018-06-21)

  • Now the Conjugator adds additional information to the Verb object returned.
    • If the verb under consideration is already in Verbiste, the conjugation for the verb is retrieved directly from memory.
    • If the verb under consideration is unknown in Verbiste, the Conjugator class now sets the boolean attribute ‘predicted’ and the float attribute confidence score to the instance of the Verb object the Conjugator.conjugate(verb) returns.
  • Added Type annotations to the whole library for robustness and ease of scaling-out.
  • The performance of the Engish and Romanian Models have improved significantly lately. I guess in a few more iteration they will be on par with the French Model which is the best performing at the moment as i have been tuning its parameters for a caouple of year now. Not so much with the other languages, but if you update regularly you will see nice improvents in the 2.2 release.
  • Enhanced the localization of the program.
  • Now the user interface of mlconjug3 is avalaible in French, Spanish, Italian, Portuguese and Romanian, in addition to English.
  • All the documentation of the project have been translated in the supported languages.

2.1.5 (2018-06-15)
