nyota ✨

Nyota is an intelligent English-speaking officer for your computer. She understands English and will carry out your every command. Well, only those commands you teach to her.

Nyota is different from other language processors, such as Siri and Google Now, in that she is built to execute actionable commands. She is not a question bot, or a conversation AI (although those might make nifty plugins), but rather an officer who awaits commands from the captain of your computer, you, and carries them out. This project is inspired by the aspiration of human-like interaction with computers.

A Plugin-Based NLP

Nyota is a Natural Language Processor capable of parsing sentences with the knowledge given to her (the knowledge of specific grammatical feature structures, or words with context). Once a sentence has been parsed, an action can be composed using the phrase's components.

Users can configure Nyota by specifying words, their appropriate grammatical contexts, and their meaning (a verb might represent a function that takes a subject and a direct object, and performs some action with them).

Installation

Clone Nyota from github:

git clone https://github.com/patgrasso/Nyota

Try It

const CFG = require('./grammar/cfg');
//const rd  = require('./parsing/shift-reduce');

let cfg = new CFG();

cfg.production('S', { name: 'NP', num: '?n' }, { name: 'VP', num: '?n' });
cfg.production('NP', 'Det', 'NP');
cfg.production('NP', 'Adj', 'NP');
cfg.production({ name: 'NP', num: '?n' }, { name: 'N', num: '?n' });
cfg.production({ name: 'VP', num: '?n' }, { name: 'V' , num: '?n' }, 'AP');
cfg.production('AP', 'Adv', 'Adj');
cfg.production('AP', 'Adj');

cfg.production({ name: 'N', num: 'sg' }, 'Nyota');
cfg.production({ name: 'V', num: 'sg' }, 'is');
cfg.production('Adv', 'very');
cfg.production('Adj', 'intelligent');

cfg.production({ name: 'N', num: 'pl' }, 'bananas');
cfg.production({ name: 'V', num: 'pl' }, 'are');
cfg.production('Adj', 'yellow');

//rd.parse('Nyota is very intelligent');
//rd.parse('bananas are yellow');

Testing

Testing Nyota requres jasmine (2.0+). All specs can be found in spec/. To run all tests, simply run npm test in the project's root.

Concepts

To gain a better understanding of NLP and the magic that makes Nyota work, take a look at NLTK and perhaps give Natural Language Processing with Python a read. They are great resources for understanding the natural language concepts that Nyota implements.
