________________________________________________________Revealing the community structure exhibited by real networks is a fundamental phase towards a comprehensive understanding of complex systems beyond the local organization of their components. Community detection techniques help on providing insights into understanding the local organization of the components of networks. In this study we identify and investigate the overlapping community structure of an interesting and unique case of study: the Estonian network of payments. In order to perform the study, we use the Clique Percolation Method and explore statistical distribution functions of the communities, where in most cases we found scale-free properties. In this network the nodes represent Estonian companies and the links represent payments done between the companies. Our study adds to the literature of complex networks by presenting the first overlapping community detection analysis of a country's network of payments. Kattuvate kommuunide tuvastamine Eesti maksevõrgustikusReaalselt eksisteerivates võrgustikes sisalduvate kommuunide tuvastamine on üheks põhietapiks teel komplekssüsteemide selliste seaduspärasuste mõistmise poole, mis lähevad sügavamale üksikelementide lokaalsete interaktsioonide käsitlemisest. Kommuunide tuvastamise meetodid aitavad heita valgust võrgustike komponentide lokaalstruktuuridele. Käesolevas uurimuses identifitseerime ja uurime kattuvate kommuunide struktuure olulises unikaalses võrgustikus -Eesti maksetevõrgustikus. Selleks otstarbeks kasutame nn klikkperkolatsiooni meetodit ja uurime kommuunide jaotusfunktsioone ning kommuunide mastaabi-invariantseid omadusi. Antud võrgustikus on sõlmpunktideks Eesti ettevõtted ja sidemeteks maksed erinevate ettevõtete vahel. Tegemist on esmakordse uurimusega, kus tuvastatakse kattuvad kommuunid ühe riigi ettevõtete vaheliste maksete võrgustikus

Este artigo tem como foco as redes de personagens, que são um tipo de rede social, apresentando propriedades de redes complexas. Para construir a rede de personagens de um filme, uma estratégia é usar o script do mesmo, que contém informações como o início de uma cena, os personagens que aparecem e diálogos. Em geral, a construção da rede social leva em conta apenas os personagens que possuem falas em cada cena. Neste trabalho, apresentamos uma metodologia que leva em consideração também personagens citados ou que apenas aparecem nas cenas. Utilizamos os filmes da franquia O Senhor dos Anéis para a aplicação da metodologia, construindo a rede de personagens e posteriormente analisando, respondendo quem são os protagonistas de acordo com três medidas de centralidade: grau ponderado, intermediação e PageRank.

“…Many researchers have raised questions about the definition of community and its structure. Shen [55] highlighted the need for a clear definition of community; he claimed that this definition is dependent on its context and applications. Tang and Liu [56] and Shen [55] defined community as a group of nodes that are densely connected with each other more frequently than with those outside the group.…”

Abstract-Current obstacles in the study of social media marketing include dealing with massive data and real-time updates have motivated to contribute solutions that can be adopted for viral marketing. Since information diffusion and social networks are the core of viral marketing, this article aims to investigate the constellation of diffusion methods for viral marketing. Studies on diffusion methods for viral marketing have applied different computational methods, but a systematic investigation of these methods has limited. Most of the literature have focused on achieving objectives such as influence maximization or community detection. Therefore, this article aims to conduct an in-depth review of works related to diffusion for viral marketing. Viral marketing has applied to business-to-consumer transactions but has seen limited adoption in business-to-business transactions. The literature review reveals a lack of new diffusion methods, especially in dynamic and large-scale networks. It also offers insights into applying various mining methods for viral marketing. It discusses some of the challenges, limitations, and future research directions of information diffusion for viral marketing. The article also introduces a viral marketing information diffusion model. The proposed model attempts to solve the dynamicity and large-scale data of social networks by adopting incremental clustering and a stochastic differential equation for business-to-business transactions.
