Decolonisation: meaning, sentiments and implications for heritage

Within the printed and online newspaper media in the UK, notions of 'decolonisation' referring to various contexts, such as historical, relating to museums and institutions, cultural decolonisation and in relation to modern independence discussions, can be traced. In this article, we have applied topic modelling and natural language processing methods to carry out a classification of, and sentiment analysis on, newspaper headlines and texts from leading British newspapers covering decolonisation over the past decade. The results show an abrupt change in the meaning of decolonisation starting in the middle of the 2010s with an increased focus on cultural and institutional matters, particularly in right-leaning media. Surprisingly, the editorial slant of broadsheets seemingly only had at best moderate effects on tone, while headlines in right-wing tabloids were significantly more negative. Articles covering cultural aspects of decolonisation were substantially more negative than those applying a more traditional, territorial definition of decolonisation. Given the influence of newspaper media on public and private opinions, we discuss the heritage implications of these findings and suggest avenues for further investigation.
