A system for recommending the optimum hashtag when posting an image on social media
Did you know that studies have found that on Twitter, tweets with more hashtags do not attract more views? This means that we now have to identify the individual hashtag that will convey a tweet’s appeal to its maximum advantage. The goal of my research is to develop a system that recommends the optimum hashtag when posting a tweet with an image attached. I hope to create a system that helps extend the reach of tweets and which is easy for anyone to use.
