Final prediction

Isobelle Roberts • 18 December 2021

Each week we rank Strictly contestants based on social media analysis. We call this the Strictly Sentiment score.


During every show we collect tweets on each contestant and extract the sentiment from them using a model that we built especially for Strictly. We use the sentiment score to rank the popularity of each contestant.

We then combine our Strictly Sentiment analysis with the judges scores to predict who will finish in the bottom two and go through to the dreaded dance off.

It's the final!


If the winner was decided by Twitter sentiment then Rose wins it.




Strictly Sentiment score


The Strictly Sentiment score is derived from a sentiment analysis of tweets. Using natural language programming and machine learning we classify each tweet as positive, neutral or negative. Tweets are filtered so that they only relate to a celebrity's appearance on the show rather than what they do in their 'day job'. Only tweets made during the show and up to the time that the public voting phone lines close are included. This is to ensure that tweets relate to Strictly.


We then add up all the positive tweets for each contestant and assign a score between 1 and 100.  This score is based on the relative distribution of positive tweets. We do this to make it easier to compare and contrast Strictly Sentiment scores.
