Nick Diakopoulos at Nieman Journalism Lab has some words of warning about the computer tools that sites like Google use on news pages: "Even robots have biases. Any decision process, whether human or algorithm, about what to include, exclude, or emphasize — processes of which Google News has many — has the potential to introduce bias." He also defines algorithm types: Summarization, personalization, optimization, ranking, association, classification, and aggregation.
