Online social networks (OSNs) play an increasingly important role in news dissemination and consumption, attracting such traditional media outlets as TV channels with growing online audiences. Online news streams require appropriate instruments for analysis. One of such tools is topic modeling (TM). However, TM has a set of limitations (the problem of topic number choice and the algorithm instability, among others) that must be addressed specifically for the task of sociological online news analysis. In this paper, we propose a full-cycle methodology for such study: from choosing the optimal topic number to the extraction of stable topics and analysis of TM results. We illustrate it with an analysis of online news stream of 164,426 messages formed by twelve national TV channels during a one-year period in a leading Russian OSN. We show that our method can easily reveal associations between news topics and user feedback, including sharing behavior. Additionally, we show how uneven distribution of document quantities and lengths over classes (TV channels) could affect TM results.
There is a paradox in the aftermath of the global imperial crisis in the region of Eastern Europe and Eurasia. The Habsburg Empire which had been thought about as the katechon of future world of federalism broke into nation-states with regimes of accommodation and repression of national minorities. The Russian Empire which had been thought about as the future centralized nation-state transformed into a federation with layered forms of autonomy and decentralization. The exploration of this paradox begins with the critique of the image of the Russian Empire as a centralized and centralizing state and exploration of inclusive and differentiated governance and ways in which this political formation was reflected in political discourses of reformist and oppositional movements which in one way or another imagined the post-imperial order. The paper then traces the constitutional debates in the revolutionary contexts of 1905 and 1917 and assesses how these debates reflected local and global discourses of imagining the post-imperial order and how they were incorporated into the constitutions adopted on the territory of the former Russian Empire. The global imperial crisis which brought down the Qing, Russian, Ottoman, German and Habsburg empires stimulated imagination of post-imperial order not only in the named contexts, but also in the British, French and other cases. The circulation and synthesis of ideas fostered by the miscellany of the crumbling empires and the diversity within each of them produced a great variety of imaginations. The non-Soviet constitutional projects of 1917–1921 and the Soviet constitutions of 1918 and 1924 incorporated the experience of the Russian Empire and other imperial and post-imperial formations. The Constitution of the Far Eastern Republic, for instance, borrowed the concept of non-territorial autonomy from the Ukrainian Constitution of 1918, while the ineffectiveness of the formal right to territorial autonomy resembled that in the Czechoslovak Constitution of 1920. The multilateral transfers and borrowings, both from the Russian imperial and other contexts, resulted in the departure of the 1924 Constitution of the Soviet Union from the initial Bolshevik plans. Instead of establishing a non-national class-centered formation, it became a mere preamble to a multinational confederation to be developed by its sovereign participants, which included two federations.
