[Feature Request] Find infinitives from conjugated forms

[picomot]

Hi @bretttolbert,

I hope you're doing great! In case you're planning to add more features to your package, here's my use case :

I have a list of sentences in French, with conjugated verbs. I am able to identify the verb (using spaCy) but I need to convert these conjugated verbs into their infinitive forms.

Eg: "Le grand-père mangeait une pomme" -spaCy-> "mangeait" (-verbecc-> "manger")

I think your Conjugator class only supports infinitive forms to conjugated forms. Do you consider adding the other way around ?

Thanks a lot for your work 😄

Best,
Victor

This is an interesting use-case. I will have to give it some thought.

Here's a very basic implementation that does what you seek using verbecc as-is:

from verbecc import Conjugator

cg = Conjugator(lang="fr")
verbs = cg.get_verbs()
all_conjugations = {}
for verb in verbs:
    conjugation = cg.conjugate(verb.infinitive)
    all_conjugations[verb] = conjugation
hash_table = {}
for verb, conjugation in all_conjugations.items():
    for mood_name, mood_value in conjugation["moods"].items():
        for tense_name, tense_value in mood_value.items():
            for person_idx, person_ending in enumerate(tense_value):
                hash_table[person_ending.split()[-1]] = (
                    f"{verb.infinitive}:{mood_name}:{tense_name}:{person_idx+1}"
                )
print(hash_table["mangeait"])

Output (where 3 = third-person singular):

manger:indicatif:imparfait:3

I agree that this is an interesting idea! Is there a way to predict the infinitive from the project website? (http://verbe.cc/)

I am learning Spanish and get a lot of great use from this project. If there is not already a way to put in a conjugated verb and get the infinitive in return, I would like to suggest the feature is added to the project website so that non-coders (such as myself) can use this feature.

@nataliateran I'm pleased you find the project useful. I appreciate the feedback. Unfortunately it's not yet possible to reverse a conjugation to its infinitive, but you and @picomot have convinced me that it will be a beneficial feature and I plan to implement it. Recently I've pushed some updates that will help facilitate this feature. E.g. it now outputs all possible inflections, including all pronouns, both masculine, feminine and misc. pronouns (e.g. Spanish vos, usted and French on), and inflects for all gender/number permutations where applicable (e.g. French verbs conjugated with auxiliary être like se lever). You will notice these changes on the verbe.cc website as well. I can't commit to a specific timeline, it could be weeks or months, as time permits, but I plan to implement a reverse lookup feature and make it accessible via the website.
