Analyzing mass media influence using natural language processing and time series analysis

Abstract: A key question of collective social behavior is related to the influence of mass media on public opinion. Different approaches have been developed to address quantitatively this issue, ranging from field experiments to mathematical models. In this work we propose a combination of tools involving natural language processing and time series analysis. We compare selected features of mass media news articles with measurable manifestation of public opinion. We apply our analysis to news articles belonging to the 20… Show more

“…The matrix H has a representation of the tweets in the topic space, in which the columns are the degree of membership of each tweet to a given topic. On the other hand, the matrix W provides the combination of terms which describes each topic [42].…”

“…The decomposition dimension was swept between 5 and 30, and for each dataset we chose a number of topics in the corpus so as to have a clear interpretation of each one. The same methodology was used and described in [11,42].…”

“…Another realistic feature at the collective level that was included in opinion models is an external mass media propaganda, which influences public opinion in the preferred direction set by the propaganda [ 25 , 37 , 38 , 39 , 40 , 41 ]. The case scenario of a propaganda that oscillates in time was considered in several studies [ 24 , 25 , 42 , 43 , 44 , 45 , 46 ] where, in analogy with spin systems in statistical physics, the propaganda can be viewed as an external oscillating field that has an influence on the opinion update of every agent.…”

“…Researchers in the field chiefly address the question of which individuals should be influenced-under a budget constraint-to achieve maximum spread. Studies on IM allow us to better understand different aspects of influencing attempts, such as under which conditions one can effectively introduce the desired opinion in a population [12,13], how influencing strategies interact when competition for influence takes place [14,15], or what the effect of external influence is on reaching consensus in a population [16].…”
