Using Twitter Streaming API to do sentiment analysis by location



I plan to use Twitter Streaming API to extract tweets based on locations ( and then do sentiment analysis based on multiple criteria. I also plan to publish this sentiment analysis information over the web.

I would like to know if I am allowed to do this and does this conform to the rules and policies set by twitter? Is there anything specific I need to be aware of?


I have the same goal with my school project. Anyone have any info on this? Also tips of good sentiment analysis tools.
