Социальные медиа: о чем и кому пишут их пользователи? Некоторые подходы к анализу данных
Прикладная эконометрика. 2017. № 3. С. 74–99.
Study of users and their segmentation, based on users’ preferred topics of discussion and their networking, is the unique opportunity offered by social networks. Variety of approaches to social media analysis based on social network analysis and text mining is summarized in the paper. It is extended by concentration index application and visualizing of the results of social network analysis.
The study of a model set exhibits that: 1) users can be successfully segmented on the base of their most mentioned topics, which is useful for a product placement and other commercial purposes; 2) distribution of number of posts by authors is highly uneven regardless to the topic of discussion; 3) users connected on-line typically live in the same geographical area; 4) users’ number of posts and centrality indices are correlated.

The article describes the second part of the research aimed at developing the framework for studying the comprehension of implicit meanings of verbal texts. The uniqueness of the proposed framework stems from the combination of psychological and linguistic methodologies. We outline the current approaches to the phenomenon of text comprehension along with its classifications available ...

Individualism–collectivism (I-C), the most widely researched cultural dimension, is often equated with Hofstede’s pioneering nation scores. Concerns are growing about these scores’ validity, but subsequent research has not produced a widely accepted alternative. Here, we offer a refined theoretical conceptualization of I-C, we systematically reevaluate the validity of Hofstede’s I-C scores, and we report the ...

Numerous studies focus on the tightness–looseness (TL) dimension of national culture, reporting important implications for business and management. However, the main TL measure has generated a number of theoretical and empirical concerns. It likely reflects unfounded national auto-stereotypes, the conceptual boundary between TL and individualism–collectivism (IC) is blurred, respondents in different societies have different TL-related ...

Contemporary theories of emotion emphasize the dual role of emotions as both personal
experiences and communicative signals during social interactions. However, the impact of
macro-level societal structures on emotional expression remains underexplored. This study
investigates the expression-experience discrepancy for self-reported emotions across nations,
focusing on how societal development relates to this discrepancy, which captures expressivity.
Using meta-analysis and multilevel modeling ...

We develop a new three-party quantum secret-sharing (QSS) protocol based on a three-qubit W state. This protocol encodes the secret-sequence bits using X gates and employs randomly selected Hadamard operations and measurement bases to generate information and security-test rounds. We evaluate the efficiency of the proposed protocol and analyze its security against an internal adversary ...

Цифровые технологии XXI века способствуют формированию новых методологических подходов в гуманитарных науках, включая литературоведение и биографические исследования. Для автоматизации процессов сбора и аннотирования информации все чаще используют большие языковые модели (Large Language Models, LLM), включая ChatGPT. Развитие подобных инструментов стимулирует переход от традиционных методологических подходов, основанных на исключительно ручном аннотировании и экспертной верификации, к гибридным, ...

This study examines the range of strategies used to encode future time reference in Standard EasternArmenian, situating them within the broader context of other Modern Armenian varieties. Illustrative data are drawn from Standard Western Armenian, the Hadrut dialect, and the Hamshen dialect. Adopting a semantic approach, we employ the term “future time reference” to delimit ...

The article continues the series of publications focused on the reassessment of the controversial Hokan hypothesis. In this paper, the traditional comparative method is applied to the reflexes of Proto-Hokan obstruents and glottal stop. The obtained results are compared to Terrence Kaufman’s (1989) reconstruction of Proto-Hokan. ...

This contribution presents three excerpts from a Modern Western Aramaic interview collected in December 2020 in Maaloula, Syria. In the interview, the narrator relates his own biographical details, the legendary life of Thecla, and a personal account of a miraculous healing. The local traditions concerning Thecla feature distinctive motifs, including the miraculous opening of the ...

We provide four equivalent combinatorial conditions for a simple assembly graph (rigid vertex graph where all vertices are of degree 1 or 4) to have the largest number of Hamiltonian sets of polygonal paths relative to its size. These conditions serve to prove the conjecture that such a maximum, which is equal to 𝐹_(2𝑛+1) −1, ...

This article explores the factors driving the regional differentiation of judicial activity in the post-reform Russian Empire. The historiography is currently divided between two poles: the paradigm of legal dualism, which postulates the alienation of rural and non-Russian (inorodtsy) populations from the Crown courts, and the opposing thesis of mass grassroots legalism, large- ly verified ...

In this paper, we construct a weighted Sobolev space of fractional order based on the
generalized Bessel potential.We apply these results to the analysis of the singular fractional Schr¨odinger
equation. To solve the Cauchy problem for this equation, we prove an estimate that relates the norm of
the solution to the norm of the initial condition in the ...

This article demonstrates that the Laplace–Bessel operator generates a strongly continuous
semigroup on a weighted Lebesgue space. Using this semigroup, we define the fractional Laplace–
Bessel operator via Balakrishnan’s formula. Furthermore, we derive three distinct representations for
fractional powers of the negative Laplace–Bessel operator. ...

In this paper, we introduce a new construction of fractional derivatives and integrals
with respect to a function, based on a matrix approach. We believe that this is a powerful
tool in both analytical and numerical calculations.We begin with the differential
operator with respect to a function that generates a semigroup. By discretizing this
operator, we obtain a matrix ...

“Leaderlessness” is widely held to be a defining feature of contemporary mass mobilization, yet the claim rests on a handful of recent cases. We offer the first systematic cross-national analysis of this phenomenon from 1791 to 2019. We show that the absence of leadership is real but older and more modest than claimed: the share ...

The carbon balance of an ecosystem is the difference between Gross Primary Productivity (GPP) and Ecosystem Respiration (Reco) as expressed by Net Ecosystem Exchange (NEE). While remote sensing retrievals of GPP have reached maturity, Reco estimation remains underexplored and ultimately cast bias on NEE.

This paper addresses the challenge of merging hierarchical navigable small world (HNSW) graphs, a critical operation for distributed systems, incremental indexing, and database compaction. We propose three algorithms for this task: Naive Graph Merge (NGM), Intra Graph Traversal Merge (IGTM), and Cross Graph Traversal Merge (CGTM). These algorithms differ in their approach to vertex selection ...

A noncommutative projective variety is defined, following Artin and Zhang, by a graded coherent algebra 𝐴. The category of coherent sheaves is then the quotient qgr(𝐴) of the category of finitely presented graded modules by the subcategory of torsion modules. We consider the categorical and polynomial entropies of the Serre twist, that is, of the ...

If a symmetric multilinear algebra is weakly nil, then it is Engel. This result may be regarded as an infinite-dimensional analogue of the well-known Jacobian theorem, which states that if a polynomial mapping has a polynomial inverse, then its Jacobian matrix is invertible.
