This proyect is composed of three applications:

General dependencies

  • Ruby 2.1.2
  • Bundler (bundler gem)
  • Nokogiri dependencies
  • MongoDB server
  • Redis server
  • elasticsearch
  • Node.js
  • Docsplit
  • FreeLing 3.1
  • Poppler 0.20+

Ruby 2.1.2

It's highly recommended that you install a Ruby version manager as RVM or Rbenv.

$ \curl -sSL | bash -s stable --ruby
$ source ~/.bashrc
$ rvm install ruby-2.1.2
$ rvm use 2.1.2 --default

We recommend rvm for installing and managing the Ruby interpreter and environment. Refer to the installation page for instructions on installing Ruby 2.1.2 with rvm.

Nokogiri dependencies

# apt-get install libxslt-dev libxml2-dev

MongoDB and Redis servers

On Debian / Ubuntu machines, install from the package manager:

# apt-get install mongodb mongodb-server redis-server


You need Java 6 (or newer) to run ElasticSearch. If on Debian / Ubuntu, you can install OpenJDK JRE from the package manager:

# apt-get install openjdk-7-jre

Then, download and install the .deb package:

$ wget
# dpkg -i elasticsearch-1.3.2.deb

Keep in mind that elasticsearch produces a large amount of logs, so it's a good idea to setup a logrotate for this tool. Also, elasticsearch needs to keep lots of files open simultaneously so you'll probably need to run this (for the elasticsearch runner user):

$ ulimint -n 32000

For more information about this issue, please read.

There are alternative downloads here.

Install Node.js

$ curl | sh
$ source ~/.bashrc
$ nvm install 0.10
$ nvm alias default 0.10

Docsplit (dependencies)

Install Docsplit dependencies

# apt-get install -y graphicsmagick poppler-utils poppler-data ghostscript pdftk libreoffice

Detailed dependencies listed in Docsplit documentation.


Download the tarball of Poppler 0.20.1 and extract it somewhere, like /usr/local/src.

Run apt-get build-dep poppler-utils to make sure you have all of its dependencies. Then, just execute ./configure, make and make install as usual.


The NER module currently uses FreeLing, an open source suite of language analyzers written in C++.


This has been tested on FreeLing 3.1. You can download the source here (147Mb~) and compile it. If you are a happy Ubuntu user, check out this link. You will be able to find .deb easily to use files.

Compile and Install

For compiling the source, you need the build-essential, libboost and libicu libraries. On Debian / Ubuntu machines, you can run:

# apt-get install build-essential libboost-dev libboost-filesystem-dev \
                  libboost-program-options-dev libboost-regex-dev \

Then, just execute ./configure, make and make install as usual.

Clone the repository

# apt-get install git
$ git clone


First, run bundle install to install all gem dependencies.

$ cd mapa76
$ cd aphrodite
$ bundle install
$ cd ../hephaestus
$ bundle install
$ cd ../aeolus

Setup your config files

Both, aphrodite and hephaestus are ruby applications and each one of them has their own configuration files. They live in ./config and they have .yml extensions. You need to adjust them to your workstation needs. For easy setup, just rename *.yml.sample to *.yml.

If the servers will be running on the same machine as Mapa76, you don't need to change anything.

Install Aeoluos dependencies

Just follow the instructions here.

Up and Running

You will need to run the aeolus file watcher:

$ cd aeolus
$ grunt w

Fire Rails app:

$ cd aphrodite
$ rails s

To start workers for document processing, you need to run at least one Resque worker:

$ cd hephaestus
$ QUEUE=* bundle exec rake resque:work

you can run multiple workers with the resque:workers task:

$ COUNT=2 QUEUE=* bundle exec rake resque:workers

And you also need to freeling as a server. The .sh file only works in OSX, but it shouldn't be hard to make it work on Ubuntu:

$ cd hephaestus
$ sh ./


  • Split workers from web app.
  • Upgrade to Rails 4.
You can’t perform that action at this time.
