Ariel – A Ruby Information Extraction Library

Ariel is a library that allows you to extract information from semi-structured documents (such as websites). It is different to existing tools because rather than expecting the developer to write rules to extract the desired information, Ariel will use a small number of labeled examples to generate and learn effective extraction rules. It is developed by Alex Bradbury and released under the MIT license. Ariel was started as a Google Summer of Code project mentored by Austin Ziegler in 2006.
