Сеть или текст? Факторы распространения протеста в социальных медиа: теория и анализ данных
Social media can act as environments that accumulate and concentrate protest sentiment before it brings people to the streets. The social ties that connect people online are similar to their offline ties, and their structure can affect the diffusion of both the protest-related information and the protest itself. In addition, social media can serve as core platforms or environments for articulating collective goals and identities. This article builds on previous scholarship that has developed these ideas, and extends it with an empirical analysis of the Venezuelan Twittersphere during the political unrest in that country.
Short messages, a.k.a. tweets, are the basic building blocks of online protest behavior on Twitter. Some of these tweets get virally retweeted and can achieve very broad audiences. These viral tweets are arguably of key importance for the articulation of the protest sentiment.
But what kind of a tweet tends to become viral? Is it a tweet posted by someone with a fortunate position in the social media network, or the one that stands out as particularly catchy or emotional? We formalize and test these competing hypotheses using two groups of empirically observable features characterizing either the author of a tweet or its content. The first group of features includes the average number of followers the users who posted a retweet have, the total number of followers the author of the original tweet has, whether the author or those who retweet are verified Twitter users, etc. The other group describes the content of the tweet and includes binary indicators of whether the tweet contains links to external platforms, emojis, question or exclamation marks. The dependent variable is the total number of retweets.
We analyze over 5.7 million unique tweets using modern data science approaches and methods (e.g. a LASSO-regression model, cross-validation, etc.) and find that the first-group features are much more informative for modeling the dependent variable. This finding turned out to be very robust and holds for both OLS and LASSO models. In addition, given the increasing importance that social media bots – i.e. automated accounts that are able to post retweet, among other things – have recently gained for political communication, we also performed robustness checks by removing bots from the analysis. We find that the network characteristics matter more than the content-related features under study.
By analyzing the logs of corporate e-mail networks we found a number of patterns, showing how the size of ego-networks of individual employees changes on a day by day basis. We proposed a simple model that adequately describes the observed time dependence of an employee's "social circle". Comparison of experimental data with the theoretical model showed that employees are divided into two groups - with fast and slow changes in their social circles, respectively. We believe that the presence of these groups reflects both project-type and process-type of employees' activities. Comparison of data obtained before and during the global economic crisis has shown that the crisis led to an actual reduction in project-type activities.
Legal pluralism and the experience of the state in the Caucasus are at the centre of this edited volume. This is a region affected by a multitude of legal orders and the book describes social action and governance in the light of this, and considers how conceptions of order are enforced, used, followed and staged in social networks and legal practice. Principally, how is the state perceived and how does it perform in both the North and South Caucasus? From elections in Dagestan and Armenia to uses of traditional law in Ingushetia and Georgia, from repression of journalism in Azerbaijan to the narrations of anti-corruption campaigns in Georgia - the text reflects the multifarious uses and performances of law and order. The collection includes approaches from different scholarly traditions and their respective theoretical background and therefore forms a unique product of multinational encounters.
The social and community driven aspects of our digital lives continue to rapidly increase, resulting in transformative behaviors and, significantly, publishing and distributing huge amounts of fascinating data. The seventh meeting of the International AAAI Conference on Weblogs and Social Media (ICWSM-13) held in Cambridge, Massachusetts, promised to be a benchmark year for ICWSM. Thanks to the enthusiastic participation of our community, we received a record number of submissions, with a growth of 50 percent over the previous year. More than the quantity, however, the high quality of the submitted papers is the truest evidence that ICWSM is maturing in its role as a premier venue for social media research.

The article discusses the phenomenon of interconnected glocal hospitality communities which have recently spread over the world in the context of the internet development and cultural globalization processes. It focuses on a typical community of users of CouchSurfi ng.org, a major social hospitality network in St. Petersburg. The author argues that, in the framework of this web service, there occurs a transformation of virtual groups of users localized in various spots of the globe into actual interconnected glocal communities which shape shared identities, norms, values, and practices among its members.
The following article is devoted to analysis of civil identity's social foundations through the actor-network theory framework. Three aspects are considered: the specific character of civic identity as a subject-object interaction between the actor and the state, the network interactions in the «real» and «virtual» spaces, social memory, social and cultural experience, socially-relevant knowledge as a basis for forming a shared social context of civic identity.
There have been implemented engineering and development of multi-agent recommender system «EZSurf» that performs analysis of interests and provides recommendations for the social network «VKontakte» users based on the data from profile of particular user. During the work process different methods and technological solutions have been analyzed with examination of their advantages and disadvantages. Besides of that the comparative analysis of analogous products has been held where the most similar is Russian start-up service - Surfingbird. Based on this analysis the decision of recommender system implementation and integration has been accepted. The feature of this system is that it uses social network “VKontakte” profile for user’s data collection and API of third-party services (LastFM, TheMovieDB) for an extraction of information about similar objects. Such an approach contributes into optimization of recommender system, because it does not require creation of its own object classification system and objects database. The functionality of multi-agent system was separated between three agents. First agent (Collector) collects user data from “VKontakte” profile using VK API. Second agent (Analyzer) collects similar objects from databases of thitd-party services (LastFM, TheMovieDB) that will be the criteria for further search of recommendatory content. For search and selection of information an agent (Recommender) that works as web-crawler has been implemented. System «EZSurf» can be exploited by the users of social network “VKontakte” in everyday life for time economy on web-surfing process. At the same time they will get recommendations on content that are filtered depending on preferences of every particular user.
The article deals with the processes of building the information society and security in the CIS in accordance with modern conditions. The main objective is to review existing mechanisms for the formation of a common information space in the Eurasian region, regarded as one of the essential aspects of international integration. The theoretical significance of the work is to determine the main controls of the regional information infrastructure, improved by the development of communication features in a rapid process.The practical component consists in determining the future policies of the region under consideration in building the information society. The study authors used historical-descriptive approach and factual analysis of events having to do with drawing the contours of today's global information society in the regional refraction.
The main result is the fact that the development of information and communication technologies, and network resources leads to increased threats of destabilization of the socio-political situation in view of the emergence of multiple centers that generate the ideological and psychological background. Keeping focused information policy can not be conceived without the collective participation of States in the first place, members of the group leaders of integration - Russia, Belarus and Kazakhstan. Currently, only produced a comprehensive approach to security in the information field in the Eurasian region, but the events in the world, largely thanks to modern technology, make the search for an exit strategy with a much higher speed. The article contributes to the science of international relations, engaging in interdisciplinary thinking that is associated with a transition period in the development of society. A study of current conditions in their relation to the current socio-political patterns of the authors leads to conclusions about the need for cooperation with the network centers of power in the modern information environment, the formation of alternative models of networking, especially in innovation and scientific and technical areas of information policy, and expanding the integration of the field in this region on the information content.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
