Internet is full of junk, there are so many anti-vaccine web sites appearing on the first page of Google search engine, and without contrasting facts alleged news spread like wildfire. Google has devised a solution consisting rank websites according to their veracity.
The Google search engine uses the number of incoming links to a website as an indicator of the quality of the site to determine where it appears in the search results. So, pages that link many other sites score higher. This is the search engine system as we know it today, but the downside is that websites full of misinformation can climb the leaderboard, if enough sites link to them.
A research team at Google is adapting this model to measure the reliability of a page, rather than its reputation through other websites. Instead of counting inbound links, the system – which is not yet available – counts the number of incorrect facts within a page. A source who has some false facts is considered to be unreliable. The score is calculated for each page is what Google calls “based on reliable knowledge score”.
The software works by scanning Knowledge Vault a large database of facts that Google has obtained from internet. Data unanimously considered a reasonable approximation to the truth. The web pages that contain conflicting information falling in the rankings.
