Alenka 👧

Alenka is a free library for predicting Russian names (and genders) from transliterated and short forms with statistical learning and Levenshtein distance.

Alenka now is not a tool for inflection (see Lvovich) or parsing first/middle/last Russian names from strings. But it will somewhen be.

Advantages

Useful for social data and media analysis.

🌀 Natively in TypeScript

🔢 Statistically trained

❤ Simple and friendly API

⚙ Configurable

Usage

Install Alenka with npm or yarn.

npm i alenka
yarn add alenka

Using with default configuration

import { NamePredictor } from "alenka";

const np = new NamePredictor();

np.predictName('Саня') // 'Александр' as more frequent
np.predictName('Саня', 'female') // 'Александра'
np.predictName('Сирожа') // 'Сергей' due to Levenstein matching
np.predictName('$one4ka') // 'София' due to transliteration rules
np.predictName('asdasda') // undefined
np.predictGender('Соня') // 'female'
np.predictAll('Саня') // [{name: 'Александр', ...}, ...]

Using with custom configuration

import { NamePredictor } from "alenka";

const options = {
    useLevenshtein: false,
    // minAcceptibleDistance: 1,
    // frequenciesSource: 'vk',
    // handlingCase: 'ignore',
    // handlingYo: 'ignore',
} as const;

const np = new NamePredictor(options);

np.predictName('Сирожа') // 'unedfined'

Terminology

1. Names are full forms of Russian Names (e.g. Александр or София);
2. Shorts are shotened forms of names (e.g. Саша or Сонечка);
3. Transliterations are latin versions of names or shorts (e.g. Alex or Sofia);
4. Variants are names, shorts and transliterations together;
5. Tokens are any strings including variatns (e.g. Саша, $0nechk@, abcdefg).

Prediction is mapping a token to a name. It happens via mathcing token against a dataset of names, shorts and transliterations with Levenshtein distance to find the closest one and return the relevant name. If nothing matched, undefined will be returned.

Contribution

Feel free to fork and leave pull requests.

To start development just run following familiar commands.

git clone https://github.com/solovevserg/alenka.git
cd alenka
yarn install
yarn test:watch

Roadmap

Here a list of actual tasks to participate at. Thanks in advance for any help.

• Fix problems with handling 'ё'
• Split in the dataset variants for shorts and tranliterations
• Finish README
• Add issues board (bug tracker)
• Add ESLint
• Add missing short forms to the data source
• Write transliteration logic (instead of cyrillic-to-translit-js)
• Optimize performance
