Wikipedia is to trial a new system which colour-codes pages depending on how "reliable" the author is.

Wikipedia has had some bad press about the reliability of entries written by its all-volunteer team.

The new program, developed at the University of California, Santa Cruz, aims to help with the problem by color-coding an entry's individual phrases based on contributors' past performance.

The program analyses Wikipedia's entire editing history - nearly 2 million pages and some 40 million edits for the English-language site alone - to estimate the trustworthiness of each page.

It then shades the text in deepening hues of orange to signal dubious content.

A 1000-page demon version is already available on a web page operated by the program's creator, link for more info below.
