Creativity Design and Cognition Gopal Kaushik – RohitSureka
Motivation • Learn about trends • Read important buzz/news • Read what other people think • Who is in the news? For what reasons? • Differentiate between positive and negative publicity
Concept • People tend to tweet what they think • There are 190 million twitter accounts! • Tweeters archive their tweets via Hashtags
What we want to do? • Find who is in the news • Find why they are in the news • Analyze twitter ‘sentiments’ for a particular topicor person
Use Case - 1 • Cricket World Cup Tracking player performances versus their presence in tweets • Who gets noticed – for the good and the bad?
Use Case - 2 • Technology tweetsFind out what people think about the latest technology products • Can also act as a community review system • E.g. What’s good in the new iPad? Merits? Flaws?
How do we do it? • Twitter feeds are public. • They can be searched by hash tags and can be parsed. • Popular words within these tweets can be stored and visualized to track the ‘buzz’ on the internet
Sentiments? How? • Sentiments can be classified by using the words used by the tweeters • Positive (Good Boy!) and Negative (Bad Boy!) words can be used to predict the trend • We can also do a temporal sentiment analysis. Find out how user sentiments change over time.
Visualization • All the data we gain needs to be suitably visualized so that people can understand what is going on! • Use information visualization techniques like Tag Clouds, Tree maps and tools like Google Visualization API , jQuery.
Who are our users? • Sports fans – to find out who is hot and who is not! • Technology Enthusiasts • Researchers – to find trends on research topics
