Twitter is a valuable data source for tapping into the opinions and behaviour of people in real time. As with most high volume unstructured data sources, pulling the signal out of the noise can often represent a significant challenge. Yesterday Twitter introduced new metadata for tweets; with the objective of helping developers pull out the most “valuable” tweets.
The problem is that “value” is highly subjective and will vary on the context within which it is being viewed. Ranking purely on the influence of the author or the sharing of an individual content item is potentially dangerous.
