Comparison of intelligence software

Which intelligence tool to use in function of the needs?

It isn't always easy to select the right intelligence solution for one's needs. The IE Portal recently published a dynamic tool presenting 44 intelligence solutions, from free Google Alert or Page Monitor type tools to payable platforms such as KB Crawl. 

Among the criteria: are you looking for a free or paid solution? What type of intelligence (media, social network, etc.)? What type of alert (email, dashboard, RSS, etc.)? Is it quick to pick up or more technical? What type of content (patents, news,Twitter, forums, etc.)?

The computer graphics are dynamic, facilitating the cross over of various parameters.
