Gaining Insight in Social Networks with Biclustering and Triclustering
P. 162–171.
We combine bi- and triclustering to analyse data collected from the Russian online social network Vkontakte. Using biclustering we extract groups of users with similar interests and find communities of users which belong to similar groups. With triclustering we reveal users' interests as tags and use them to describe Vkontakte groups. After this social tagging process we can recommend to a particular user relevant groups to join or new friends from interesting groups which have a similar taste. We present some preliminary results and explain how we are going to apply these methods on massive data repositories.

This paper dates back to the asymptotic solutions of Rota’s problem on the size of maximum antichain in the set partition lattice by Canfield and Harper and others. The knowledge of asymptotic coefficients could pave the way to the asymptotic solutions of such problems as (maximal) antichain counting in partition lattices. In addition to our ...

The article, based on semi-structured in-depth interviews, examines how the practices of social network users have changed in context of two problematic situations: restrictions associated with the covid-19 pandemic and blocking of popular Internet resources. It is noted that with a high level of access to the Internet, a restructuring of the media practice system ...

Background: The outbreak of SARS-CoV-2 in 2019 was accompanied by a rise in the popularity of conspiracy theories. These theories often undermined vaccination efforts. There is evidence that the spread of misinformation about COVID-19 is associated with online social media use. Online social media enables network effects that influence the dissemination of information. It is important ...

We consider two ways how to compute the number of maximal antichains in the Boolean lattice on 𝑛 elements. The first one is based on full direct enumeration, while the second ones relies on concept lattices or Galois lattices (studied in Formal Concept Analysis, an applied branch of lattice theory) and the Dedekind–MacNeille completion of a partial ...

The study analyzes the time series of the number of new cases in the administrative courts
of the Russian Federation using two methods of time series grouping according to the chaotic, stochastic, and
regular structure. The first model is based on the entropy‒complexity plane, the second one is presented by the
attribute‒object graph. As a result, four groups ...

В докладе рассматриваются подходы к прогнозированию на основе кластеризации, опирающиеся на методологию анализа формальных понятий. Методология применяется для кластеризации участков временного ряда с целью выделения характерных участков (мотивов), отвечающих больным с различной степенью засорённости фистулы. ...

This paper presents different versions of classification ensemble methods based on pattern structures. Each of these methods is described and tested on multiple datasets (including datasets with exclusively numerical and exclusively nominal features). As a baseline model Random Forest generation is used. For some classification tasks the classification algorithms based on pattern structures showed better ...

© 2021, Springer Nature Switzerland AG.Missing genotypes can affect the efficacy of machine learning approaches to identify the risk genetic variants of common diseases and traits. The problem occurs when genotypic data are collected from different experiments with different DNA microarrays, each being characterised by its pattern of uncalled (missing) genotypes. This can prevent the ...

Abstract: The paper deals with the problem of triclustering in multivalued triadic contexts in termsof one multidimensional extension of formal concept analysis; triclustering can be viewed as asearch for dense subtensors in three-dimensional tensors over the field of real numbers. Twomethods are proposed for solving this problem, namely, NOAC—a version of the OACtriclustering method for ...

The article discusses the actual sociological problem of interrelation of ontological and epistemological bases in the study of social space. The authors draw attention to the fragmentation of Internet space research and aim to analyze the transformation of scientific approaches to the problem of social space in the process of nderstanding the new ontology of ...

В разговоре об алгоритмах, их влиянии на коллективное и индивидуальное восприятие соцсетей, на мой взгляд, важен конфликт очищенных от контекста больших данных, на которые так любят ссылаться маркетологи и аналитики, и пользовательских практик, пронизанных аффектами и догадками. Даже имея большие
данные, например, подробную статистику пользователей с учетом возраста,
гендера, территориальной принадлежности пользователей, исследователи и маркетологи часто не ...

Ensembles of decision trees, like Random Forests are efficient machine learning models with state-of-the-art prediction quality. However, their predictions are much less transparent than those of a single decision tree. In this paper, we describe a prediction model based on a single decision tree in terms of Formal Concept Analysis. We define a differential way ...

The article reveals the issues of expanded understanding of self-presentation viewed as an integral component of any communicative act, as the socio-cultural behaviour, and also as a means of controlling the impression a person makes on others in the process of interaction. As communication through social networks is becoming an increasingly common element of modern ...

Social tie maintenance has always had cognitive and emotional costs and has always been leading to uneven distribution of communication volume among egos' alters. This distribution, known as a social signature, is assumed to be relatively stable for each individual. Availability of digital traces of human communication allows testing
whether this assumption is true and whether it holds in specific ...
