Community detection in Social Media

The past decade has witnessed the emergence of participatory Web and social media, bringing people together in many creative ways. Millions of users are playing, tagging, working, and socializing online, demonstrating new forms of collaboration, communication, and intelligence that were hardly imaginable just a short time ago. Social media also helps reshape business models, sway opinions and emotions, and opens up numerous possibilities to study human interaction and collective behavior in an unparalleled scale. This lecture, from a data mining perspective, introduces characteristics of social media, reviews representative tasks of computing with social media, and illustrates associated challenges. It introduces basic concepts, presents state-of-the-art algorithms with easy-to-understand examples, and recommends effective evaluation methods. In particular, we discuss graph-based community detection techniques and many important extensions that handle dynamic, heterogeneous networks in social media.

Social media mining is the process of obtaining big data from user-generated content on social media sites and mobile apps in order to extract patterns, form conclusions about users, and act upon the information, often for the purpose of advertising to users or conducting research. The term is an analogy to the resource extraction process of mining for rare minerals. Resource extraction mining requires mining companies to sift through vast quantities of raw ore to find the precious minerals; likewise, social media mining requires human data analysts and automated software programs to sift through massive amounts of raw social media data in order to discern patterns and trends relating to social media usage, online behaviours, sharing of content, connections between individuals, online buying behaviour, and more. These patterns and trends are of interest to companies, governments and not-for-profit organizations, as these organizations can use these patterns and trends to design their strategies or introduce new programs, new products, processes or services. Social media mining uses a range of basic concepts from computer science , data mining , machine learning and statistics. Social media miners develop algorithms suitable for investigating massive files of social media data.

For a broad range of research and practical applications it is important to understand the allegiances, communities and structure of key players in society. One promising direction towards extracting this information is to exploit the rich relational data in digital social networks the social graph. As global social networks e. Distributing graph processing requires solving many difficult engineering problems, which has lead some researchers to look at single-machine solutions that are faster and easier to maintain. In this article, we present an approach for analyzing full social networks on a standard laptop, allowing for interactive exploration of the communities in the locality of a set of user specified query vertices. The key idea is that the aggregate actions of large numbers of users can be compressed into a data structure that encapsulates the edge weights between vertices in a derived graph.

Social media mining

The proposed survey discusses the topic of community detection in the context of Social Media. Community detection constitutes a significant tool for the analysis of complex networks by enabling the study of mesoscopic structures that are often associated with organizational and functional characteristics of the underlying networks. Community detection has proven to be valuable in a series of domains, e.

 - Когда мистер Беккер найдет ключ, он будет вознагражден сполна. ГЛАВА 22 Дэвид Беккер быстро подошел к койке и посмотрел на спящего старика. Правое запястье в гипсе. На вид за шестьдесят, может быть, около семидесяти.

Он не привык, чтобы кто-то повышал на него голос, пусть даже это был его главный криптограф. Он немного смешался. Сьюзан напряглась как тигрица, защищающая своего детеныша.

Это было другое кольцо - платиновое, с крупным сверкающим бриллиантом. Сьюзан охнула. Дэвид посмотрел ей в глаза: - Ты выйдешь за меня замуж. У нее перехватило дыхание. Она посмотрела на него, потом на кольцо. Глаза ее увлажнились. - О, Дэвид… у меня нет слов.
