Project Description

Constractor (derived from “Content Extractor’) allows one to use machine learning for web pages content extraction. Library provide following functionality:

  • Extendable features api.
  • Gui tools for simple train-set creation.
  • Simple training and testing process.
  • Simple usage of trained model.
  • Models dumping.
  • etc


NOTE: Project was developed and tested under Ubuntu 12.04. Other operation systems may require enhancements of library.

Ubuntu >=12.04 instructions:

  • Install apt dependecies: sudo apt-get install pip gcc g++ python-dev python-qt4
  • Install constractor: sudo pip install constractor


Following code will run gui train helper:

#!/usr/bin/env python
from constractor.train import GuiTrainer

if __name__ == '__main__':

And following code will print html of predicted element in DOM:

#!/usr/bin/env python
from constractor.parser import Parser

if __name__ == '__main__':
    predicted = Parser('', model_file='model.txt').predicted
    for element in predicted:
        print unicode(element.toInnerXml()).encode('utf-8')
