If you are looking for a scrapper, ie to crawl and extract data from a website for Price Management, Marketing, update on football score, news clipping, etc…. the Scrapinghub team have announced the release of Portia, an open source visual web scrapper.
Portia allows you to extract data in a very intuitive way without the need of programming knowledge. You just need to annotate web pages and indicate what data to extract (From the visual editor) and Portia will learn how to scrape similar pages from the website.
Check out the demonstration video:
You can download Portia or contribute to the project through Github here.
