• Extract 100 million facts (CC0) from the scientific literature per year

• Grow communities and give everyonethe tools and know-how to mine science

What is “Content”?

contentmine.org tackles these

Machine-Human symbioses

• Wikipedia

• Open StreetMap

• Google

We aim to make it trivial for a human+machineto mine the scientific literature.

By building Communities

Workshops and Hackdays

• CRAWL the web for scientific documents(articles, grey literature, repositories)• quickSCRAPE pages (text, graphics, images, data)• NORMA-lize page to semantic form

…Open semantic science …• MINE pages with your methods and tools (AMI)

• CAT-alogue results in searchable index• Automate daily process (CANARY)

CRAWLing the Literature

NO Central Table of Contents

Massive technical, political, legal opposition

Little interest from Academia

Tedious

Few general tools
