I initially suggested a universal notification/news feed manager in which you can sign in with multiple accounts(Facebook, Twitter etc) and the app removes any redundant posts that may appear on two or more of those accounts. Also, some flexibility on what the user wants in the news feed can be provided. My second idea was a food wastage prevention app in which you can take photos of soiled plates at restaurants/canteens and the app does image processing and runs the data against a database of previously stored data from said image processing and calculates which food item(s) have the highest probability of being wasted. These items can be removed from the menu in the future and it will save a lot of resources. Also, it will save the restaurant/canteen a lot of money in the long run.
We basically want to work with sentiment analysis. We want to figure out how people have responded to products based on their social presence.
