Horseman Article Parser

A web page article parser which returns an object containing the article's formatted text & other attributes including sentiment, keyphrases, people, places, organisations and spelling suggestions.

Prerequisites

Node.js & NPM

Install

npm install horseman-article-parser --save

Usage Example

var parser = require('horseman-article-parser');

var options = {
  userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36',
  url: "https://www.theguardian.com/politics/2018/sep/24/theresa-may-calls-for-immigration-based-on-skills-and-wealth"
}

parser.parseArticle(options)
  .then(function (article) {

    var response = {
      title: article.title.text,
      metadescription: article.meta.description.text,
      url: article.url,
      sentiment: { score: article.sentiment.score, comparative: article.sentiment.comparative },
      keyphrases: article.processed.keyphrases,
      people: article.people,
      orgs: article.orgs,
      places: article.places,
      text: {
        raw: article.processed.text.raw,
        formatted: article.processed.text.formatted,
        html: article.processed.text.html
      },
      spelling: article.spelling
    }

    console.log(response);
  })
  .catch(function (error) {
    console.log(error.message)
    console.log(error.stack);
  })

parseArticle(options, <socket>) accepts an optional socket for pipeing the response object, status messages and errors to a front end UI.

See horseman-article-parser-ui as an example.

Options

The options below are set by default

var options = {
  userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36',
  // node-horsman options (https://ghub.io/node-horseman)
  horseman: {
    timeout: 10000, 
    cookies: './cookies.json'
  },
  // clean-html options (https://ghub.io/clean-html)
  cleanhtml: {
    'add-remove-tags': ['blockquote', 'span'],
    'remove-empty-tags': ['span'],
    'replace-nbsp': true
  },
  // html-to-text options (https://ghub.io/html-to-text)
  htmltotext: {
    wordwrap: 100,
    noLinkBrackets: true,
    ignoreHref: true,
    tables: true,
    uppercaseHeadings: true
  },
  // retext-keywords options (https://ghub.io/retext-keywords)
  retextkeywords: { maximum: 10 }
}

At a minimum you should pass a url

var options = {
  url: "https://www.theguardian.com/politics/2018/sep/24/theresa-may-calls-for-immigration-based-on-skills-and-wealth"
}

there are some additional "complex" options available

var options = {
  // array of html elements to stip before analysis
  striptags: [],
  // readability options (https://ghub.io/node-readability)
  readability: {},
  // retext spell options (https://ghub.io/retext-spell)
  retextspell: {}
}
