YOUTUBE SOCIAL NETWORK

Article analyzes Youtube definition, youtube advantages and disadvantages, youtube advertising. Thanks to Youtube, a larger number of users can be reached and allows you to see the reaction of the players to the video advertising. YouTube is one of the most popular sites on the world, which receives millions of impressions annually and spends millions of content makers that it has. The profit earned through YouTube comes from advertising. Content developers who post ads in their videos receive about half of the revenue generated by these ads. Youtube is a social network that allows you to make money

The Untold Story of the Clones: Content-agnostic Factors that Impact YouTube Video Popularity

Video dissemination through sites such as YouTube can have widespread impacts on opinions, thoughts, and cultures. Not all videos will reach the same popularity and have the same impact. Popularity differences arise not only because of differences in video content, but also because of other "content-agnostic" factors. The latter factors are of considerable interest but it has been difficult to accurately study them. For example, videos uploaded by users with large social networks may tend to be more popular because they tend to have more interesting content, not because social network size has a substantial direct impact on popularity. In this paper, we develop and apply a methodology that is able to accurately assess, both qualitatively and quantitatively, the impacts of various content-agnostic factors on video popularity. When controlling for video content, we observe a strong linear "rich-get-richer" behavior, with the total number of previous views as the most important factor except for very young videos. The second most important factor is found to be video age. We analyze a number of phenomena that may contribute to rich-get-richer, including the first-mover advantage, and search bias towards popular videos. For young videos we find that factors other than the total number of previous views, such as uploader characteristics and number of keywords, become relatively more important. Our findings also confirm that inaccurate conclusions can be reached when not controlling for content.Comment: Dataset available at: http://www.ida.liu.se/~nikca/papers/kdd12.htm

La société recommandée: De la conjecture de von Foerster aux sciences sociales prédictives

The conjecture of von Foerster describes the circular causal relationship between a whole (eg, a human community) and its elements (individual members). It establishes that when the relationship between individuals become more and more "rigid" (social influence is getting stronger) the behavior of the whole could appear, to the individual elements that compose it, as an autonomous dynamics beyond their control, despite the fact it will be more predictable by an outside observer. While at the time of this conjecture in 1987, few people were inclined to accept the idea that a theorem could account for social dynamics, or even predict them, we show that information and communication technologies (ICT), which have become ubiquitous in our societies, provide both an example of what von Foerster called "rigid relations" between individuals, a testing ground and an empirical validation of this conjecture. We then explore the societal consequences of the conjecture.La conjecture de von Foerster décrit le rapport de causalité circulaire entre une totalité (par exemple, une collectivité humaine) et ses éléments (les individus qui la composent). Elle établi que plus les relation inter-individuelles sont "rigides" (plus l'influence sociale est forte) plus le comportement de la totalité apparaîtra aux éléments individuels qui la composent comme dotée d'une dynamique propre qui échappe à leur maîtrise alors qu'elle sera d'autant plus prédicible par un observateur extérieur. Alors qu'en 1987 lors de sa formulation, peu de gens étaient enclins à accepter l'idée qu'un théorème puisse rendre compte de dynamiques sociales, voire les prédire, nous montrons que les technologies de l'information et de communication (TIC), devenues ubiquitaires dans nos sociétés, nous donnent à la fois un exemple de ce que von Foerster appelait " relations rigides " entre individus, un terrain d'expérimentation et une validation empirique de cette conjecture. Nous en explorons ensuite les conséquences sociétales

A Network View of Social Media Platform History: Social Structure, Dynamics and Content on YouTube

Social media sites are prone to change from many internal and external causes, yet it is difficult to directly explore their histories in terms of the content itself. Search and browsing features are biased toward new and paid content, archives are difficult to navigate systematically, and their scale makes any observations challenging to contextualize. Here, we present results of an ongoing study of YouTube’s history (currently with more than 76 million videos) using a combination of iterative browsing, network crawling and clustering within and across time periods. Through this method, we are able to identify historical patterns in YouTube\u27s content related to internal and external events. Our approach thus illustrates an adaptation of network analysis for understanding genre evolution in the histories of social media platforms
