I'm trying to build a web application that compiles the trends in a particular vertical around mentions of people's names as a gauge of popularity. I was planning to use the Ellerdale Project's API but they're shutting it down after getting acquired.
The use case would look something like Ellerdale's illustration but for a different type of vertical: http://trends.ellerdale.com/trends/politics I'd like to query the twitter API to get number of mentions/messages relating to a name over a defined period of time (1 hour, 1 day). Is it possible to do this? Seems like you need access to the firehose and have a very compute-intensive back-end to derive this. Or is there another aggregation service with an API you know of? Thanks Neil
