concepts-parser

Nodejs module for extracting concepts from text.

A Concept is a part of a text that may be a Named entity. We use Concepts for learning new named-entities, for searching known entities, for identifying entity names(synonyms, abbreviations), etc.

Usage

JavaScript:

const parser = require('concepts-parser');

const concepts = parser.parse({ text: 'Some text', lang: 'ru', country: 'ru' });

TypeScript:

import { parse } from 'concepts-parser';

const concepts = parse({ text: 'Some text', lang: 'ru', country: 'ru '});
