How it works?

"Quantum Times" is a computer generated news service, with no human editors in background. "Quantum Times" uses completely automated algorithms to display the most popular news stories. To do so, it evaluates several news parameters like the number of news sources a story appeared in, date of publication, etc. It also automatically match news stories to appropriate categories based on news content.
