Inflex

Natural Language Inflection in English<br> (Formerly called Inflexion)

Overview

The Inflex module is a rule-based morphological analyser and generator. It allows for conversions of any noun, verb or adjective to a specific wordform such as singular, plural, past, past participle or present participle.

Inflex can be tried out and compared against competitors including nltk, textblob, pattern, inflect, inflection, inflector, lemminflect, and pyinflect on https://www.tomaarsen.com/projects/inflex/try. Furthermore, the comparison of performance of all of these modules is visualised on https://www.tomaarsen.com/projects/inflex/performance, using several different datasets. These results show that Inflex outperforms all existing modules for noun conversions, and performs competitively for verbs. This website also contains the thesis out of which Inflex (formerly called Inflexion) was born.

The Inflex documentation can be found here, alongside a Quick Reference.

Sample Usage

from inflex import Noun, Verb, Adjective

# Converting Nouns
Noun("book").plural()   # Produces "books"

# Converting Verbs
Verb("fly").plural()    # Produces "fly"
Verb("fly").singular()  # Produces "flies"
Verb("fly").past()      # Produces "flew"
Verb("fly").pres_part() # Produces "flying"
Verb("fly").past_part() # Produces "flown"

# Converting Adjectives
Adjective("my").singular()       # Produces "my"
