The invisible web:what are you missing?

Hanna Back, 22 de Maio, 2009.

All information in the web is available for everyone, if you can google it, you can access it, at least that is what everyone thinks, but there are contents that are in formats or embedded in databases that can’t be accessed by search engines as Google and Yahoo, which means that you don’t see it. This is the Invisible web.

Non-descriptive titles, unreadable or un-indexable content (doc,pdf,xls,ppt) by search engines, files embedded in the depths of databases, makes the most of the invisible web.

The main issue: most of that information is relevant data: academic research, official stats, market information.

There are some efforts being done to reveal the info:Google Scholar, Google Public Data visualization, the Wolfram Alpha search engine and Slideshare are some of the tools available for it. But the efforts are slow and information goes outdated really quick. The solution? access and search directly. Where? see the list below:
