"software that color-codes Wikipedia entries, identifying those portions deemed trustworthy and those that might be taken with a grain of salt.
To determine which passages make the grade, the researchers analyzed Wikipedia's editing history, tracking material that has remained on the site for a long time and edits that have been quickly overruled. A Wikipedian with a distinguished record of unchanged edits is declared trustworthy, and his or her contributions are left untouched on the Santa Cruz team's color-coded pages. But a contributor whose posts have frequently been changed or deleted is considered suspect, and his or her content is highlighted in orange. (The darker the orange, the more spurious the content is thought to be.)"
