Repository Details

Pure ruby implementation of the Boilerpipe content extraction algorithm tuned for online articles

Boilerpipe

CircleCI Gem Version

A pure ruby implemenation of the boilerpipe algorithm.

This is a text extraction utility first written by Christian Kohlshutter - presentation

I went directly to the original author's github https://github.com/kohlschutter/boilerpipe and forked that code base here https://github.com/gregors/boilerpipe.

I saw other gems making use of boilerpipe via the free api but depending on time of day the api goes down due to exceeding the hosting plan. I also checked out some gems making use of Jruby but I had all kinds of dependency and bug issues. So I made some tweaks on my fork and created a new jruby-boilerpipe gem.

This solution works great if you're using Jruby but I wanted a pure ruby solution to use on MRI. Open vim - start coding...

Here's a high level diagram of how the system works.

TLDR

Just use either ArticleExtractor, DefaultExtractor or KeepEverythingExtractor - try out the others when you feel like experimenting...

Presently the follow Extractors are implemented

  • ArticleExtractor
  • ArticleSentenceExtractor
  • CanolaExtractor
  • DefaultExtractor
  • KeepEverythingExtractor
  • KeepEverythingWithMinKWordsExtractor
  • LargestContentExtractor
  • NumWordsRulesExtractor

Installation

Add this line to your application's Gemfile:

gem 'boilerpipe-ruby', require: 'boilerpipe'

And then execute:

$ bundle

Or install it yourself as:

$ gem install boilerpipe-ruby

Usage

gregors$ irb
> require 'boilerpipe'
 => true
> require 'open-uri'
  => true
> content = open('https://blog.carbonfive.com/2017/08/28/always-squash-and-rebase-your-git-commits/').read; true;

> Boilerpipe::Extractors::ArticleExtractor.text(content).slice(0..40)
 => "Always Squash and Rebase your Git Commits" 

> Boilerpipe::Extractors::DefaultExtractor.text(content).slice(0..40)
 => "Posted on\nWhat is the squash rebase workf"

> Boilerpipe::Extractors::LargestContentExtractor.text(content).slice(0, 40)
 => "git push origin master\nWhy should you ad"

> Boilerpipe::Extractors::KeepEverythingExtractor.text(content).slice(0..40)
 => "Toggle Navigation\nCarbon Five\nAbout\nWork\n"

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.

Running Tests on Docker

The default run command will run the tests

docker build -t boilerpipe .
docker run -it --rm boilerpipe
