I'm completing an MSc in Science Communication and part of it is to analyse a social media campaign. I use twitter and basic analytics but for this I need to access data from a set time frame (28 Jan - 11 Feb), from geographic region, in English and using campaign # or associated key words. I was going to use NodeXL, then looked at Tweet Archivist but getting myself confused - any advice, recommendations etc. I can pay for a temp package if required.
