I would think that an automated system would have less ad-hoc bias.
It would report on whatever triggers newsworthiness[1] rather than whatever gains the attention of a reporter (which would have fewer if any stated minimums or maximum requirements).
Concretely speaking it's the difference between human-curated search engines and automated search engines like Google.
[1] Since such a system would require thought and design, there would be less impulsive influence.
