context-url-extractor

Methods for extracting URLs from HTML or text strings with surrounding context

When data mining content that contains URLs, it's far easier for a machine to categorise them if they are semantic (or friendly) URLs:

Bad URL

• http://example.com?country=19&province=2

Good URL

• http://example.com/americas/canada/quebec

This package provides a jumping off point for data mining the surrounding context of each URL found in the supplied content.
