The Royal Birth of 2013:Analysing and Visualising Public Sentiment in the UK Using Twitter
TABLE II: Correlation ratio between the dictionary-based and the machine learning approaches
['[BOLD] Country', '[BOLD] No. of Tweets', '[BOLD] Correlation Ratio']
Further, a correlation analysis between the PSS obtained from both the approaches was performed. Given the large volume of tweets analysed for England, there is a large correlation of over 80% between the results produced by both the approaches. The two approaches produce least correlated results for Wales, and the correlation ratios for Scotland and N. Ireland are not high. This is perhaps because the analysis on larger volumes of tweets can produce higher quality of results.
