Sentiment analysis

Measure sentiment with machine learning

A multinational company wanted to track user sentiment about its brand on Twitter so it could extract and measure customer perceptions to help inform its advertising and marketing campaigns.


Measure brand sentiment.

To track and measure user sentiment, we needed to build a model that would enable us to aggregate the opinions of our client’s Twitter audience over a period of time.

Online chatter can be poorly written and unclear, so our first task was to create a framework to disambiguate the tweets. To meet this challenge, we built a real-time tracker for tweets that used specific hashtags and handles, including tags that referenced our client’s competitors.

After we created a framework to identify, clarify, and target relevant tweets, we then analyzed those tweets to decide if the tweets were positive (favorable) or negative (unfavorable). Once we quantified that data, we were able to chart customer sentiment about our client’s brand versus customer sentiment about competitive brands over a period of time.
