DETERMINING THE LEVEL OF PROPAGANDA IN OPERA LIBRETTOS USING DATA MINING AND MACHINE LEARNING - Research paper

Aug 4, 2026

The article presents an adapted multifactorial model for determining the level of propaganda in librettos for world operas. The method is built using linear convolution with eight carefully selected indicators that capture key propaganda elements while reflecting domain-specific textual characteristics. Each indicator is computed through statistical analysis supported by data mining and machine learning. The resulting value function is produced for every libretto, enabling classification of whether propaganda elements are present.

DATS, O. GAVRILENKO, K. FESHCHENKO Abstract. The article presents an adapted multifactorial model that can be used to determine the level of propaganda in librettos to world operas. This model was created using the linear convolution method, for which eight indicators were selected that are most effective in identifying elements of propaganda in the text, taking into account the subject area's peculiarities. Each of the selected indicators was calculated using statistical analysis, data mining, and machine learning methods. As a result of applying the proposed method, the value function is calculated for each libretto, based on which a conclusion is made as to whether it contains elements of propaganda or not. Keywords: art, propaganda, opera, libretto, multivariate model, statistical analysis, Data Mining, Machine Learning, information technology. INTRODUCTION Propaganda in art is the use of artistic forms to influence public opinion, shape ideas, and spread specific ideologies or political views. It can be both explicit and subtle, serving as an instrument of the state, religion, or social movements. When studying the factors that influence human opinions in various areas of activity, it is worth paying attention to the vast and diverse realm of “agitation” in art. Since classical times, this has included visual and monumental art; during the Renaissance, masterpieces carried propaganda of a new era for humanity. Later, theatrical art acquired a dual meaning, while musical compositions and cinema, with their strong emotional impact, took on a special role in global propaganda. The development of propaganda in art is based on: 􀁸 The promotion of an individual or a collective’s creative activity (promotional advertising), which helped advance the careers of “useful” figures in the creative field. 􀁸 The involvement of specialists in the propaganda of artistic products, where musical content and literary foundations contributed to patriotic songwriting (particularly from the perspective of socialist state leaders) . Quite often, musical works used for propaganda incorporated compositions by other composers or folk songs, embedding entirely new meanings into them. For example: The anthem of the USSR (at least its musical material) was taken from Mykola Lysenko’s “Epic Fragment”, whose impact and emotional depth made it highly suitable for Soviet state propaganda. The agitational song “Far Beyond the River”, which fully adopted a Ukrainian insurgent song about a fallen hero, was repurposed by the Red Army to promote the fight against what they considered old and bourgeois elements. 􀂤 Publisher IASA at the Igor Sikorsky Kyiv Polytechnic Institute, 2025 Системні дослідження та інформаційні технології, 2025, № 2 81 These are just a few examples of musical works that, in addition to raising issues of plagiarism in music, also highlight the problem of identifying propaganda. Due to the vast diversity of art forms, this article focuses on the propagandistic impact on opera audiences, considering opera as a genre with along history, an elite form of art, and a significant part of world culture. Propaganda in opera has been particularly evident in productions staged in China [1], Nazi Germany, and the Soviet Union. For example, the works of Richard Wagner, which glorify ancient Germanic legends, were used to emphasize the superiority of the German nation and the Aryan race, reinforcing the ideology of world domination. Similarly, the soviet regime implemented propaganda slogans by repurposing older russian operas and creating new, ideologically charged soviet works that praised and glorified the soviet government, its achievements, and way of life.

FAQs

What is the main goal of the proposed method?

To determine the level of propaganda in opera librettos by computing a value function for each libretto and concluding whether propaganda elements are present.

How is the model constructed and what indicators are used?

It uses an adapted multifactorial approach based on linear convolution, selecting eight indicators that are effective for identifying propaganda elements in the text while accounting for domain specifics.

Which techniques are employed to calculate the indicators and support the conclusion?

The indicators are calculated using statistical analysis, data mining, and machine learning methods, after which the computed function enables the final classification.
