Based on my existing website

Hi my site is [login to view URL] . we display news based on country and after clicking on map , you can see the news changes based on that country . I want to change the concept to : - instead of displaying the news , we will have a search box . users can search for country , city , university , etc and get news results / tweets / videos / ( as we currently have ) but the results of the search will be like [login to view URL] ( our own demo site for stocks) - so here we can filter the news we get and tweets into keywords (Negative and positive keywords ) and the more of one or the other , then the gauge will turn positve or negative . same as the stock research demo . so if there are 500 positive and 1200 negative then goes toward negative and will link to the news articles as we have now . - we will agree on the keywords later on which can be positive and negative . - we currently import from google news . -we can also make a tag cloud and the the most repeated tag bigger based on frequency . so if killing is repeated the most then will be bigger then something smaller etc ...
