AUTHORS are gradually using less emotionally-charged words in their books over time, according to new joint-research by Sheffield University staff with colleagues from Bristol and Durham.
The study found ‘mood words’ – anger, disgust, fear, joy, sadness and surprise – are being used in novels less today when compared against novels from last century.
Researchers charted the use of the words from a database of more than five million digitised books. The information was provided by internet search engine Google.
Dr Vasileios Lampos, from Sheffield University’s computer science and natural language processing group department, said there was also a clear link between historical events such as World War II and emotional language in literature.
