Web Data Extractors 2016

Extracting data from the World Wide Web (WWW) has become an important issue in the last few years as the number of web pages available on the visible Internet has grown to over 20 billion pages with over 1 trillion pages available from the invisible web. Tools and protocols to extract all this information have now come in demand as researchers as well as web browsers and surfers want to discover new knowledge at an ever increasing rate! As robots (bots) and intelligent agents are at the heart of many extraction tools I decided to create a compilation of the latest sources and sites that extract information from the web. There are a number of eMail extraction tools still available through the Internet and I have decided not to list these as they aid to the on-going and increasing problem of SPAM except for a readily available DMOZ Directory listing:
