The BuzzMentions Political Index
http://election2015.buzzmentions.com/
What
It was built to give you insight into what people are discussing about the 2 major Presidential candidates of the 2015 Nigerian Elections, President Goodluck Ebele Jonathan and General Muhammadu Buhari. It aims to enhance understanding of political dynamics in Nigeria by analyzing the tone and intensity of the online political conversation that is going on in this country. It is the product of a partnership between Buzzmentions and OpenAmplify.

How
It was modeled after 'Twindex', an election enthusiasm tracker built by Twitter for the last US elections. Buzzmentions media monitoring engine scans through news articles (local and international), blogs, Youtube, Facebook, Twitter etc for mentions of "Goodluck Jonathan" and "Buhari". The OpenAmplify Insights engine then analyzes mentions trying to detect the sentiment (emotion), age range of writer and language style. OpenAmplify is a world-renowned NLP (natural language processing) text analysis engine with over 20 years of NLP research and 15 granted patents. We are also tracking entities (person, city and organization) in the posts so we can determine discussion themes.

This is a very silly dashboard based on false analytics. The trend for previous months were not as good for Jonathan and Buhari's positive perception is actually much wider than Jonathan than was shown in the graphs.

Are you speaking based on emotions or fact. This is a research work, you can only counter with facts.
