Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory.
 It characterizes networked structures in terms of "nodes" (individual actors, people, or things within the network) and the "ties", "edges", or "links" (relationships or interactions) that connect them.
 Examples of social structures commonly visualized through social network analysis include social media networks, memes spread, friendship and acquaintance networks, collaboration graphs, kinship, disease transmission, and sexual relationships.
 These networks are often visualized through "sociograms" in which nodes are represented as points and ties are represented as lines.
Filmow is a Brazil-based collaborative social network where users list the films and series they have watched or would like to watch, having the option of giving a review of up to 5 stars.
 The user shares its registered film library with friends.
 In addition, the site also has the basic functions of a social network where the user can meet new people and make new friends.
 It was founded by Alisson Patrício and Thais Lima, and it was launched on April 1, 2009.
A social network game is a type of online game that is played through social networks.
 They typically feature multiplayer gameplay mechanics.
 Social network games were originally implemented as browser games.
 As mobile gaming took off, the games moved to mobile as well.
 While they share many aspects of traditional video games, social network games often employ additional ones that make them distinct.
 Traditionally they are oriented to be casual games.
The International Network for Social Network Analysis (INSNA) is a professional academic association of researchers and practitioners of social network analysis.
 Members have interests in social networks as a new theoretical paradigm, in methodological developments, and in a variety of applications of different types of social networks approaches, social network software, and social networking.
A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors.
 The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures.
 The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics.
Bananagrams is an online social game developed by Large Animal Games in partnership with Majesco Entertainment.
 It launched on Facebook on November 17, 2008.
 Success of the Bananagrams tile game developed by the Nathanson family prompted Bananagrams International to extend the brand online.
 Bananagrams was later released on Bebo and MySpace.
Social network aggregation is the process of collecting content from multiple social network services, such as Instagram, Tumblr, Flickr, LinkedIn, Twitch, YouTube, etc. into one unified presentation.
 The task is often performed by a social network aggregator (such as Hootsuite and FriendFeed), which pulls together information into a single location, or helps a user consolidate multiple social networking profiles into one profile.
 Various aggregation services provide tools or widgets to allow users to consolidate messages, track friends, combine bookmarks, search across multiple social networking sites, read RSS feeds for multiple social networks, see when their name is mentioned on various sites, access their profiles from a single interface, provide "lifestreams", etc.
 Social network aggregation services attempt to organize or simplify a user's social networking experience, although the idea has been satirized by the concept of a "social network aggregator".

Chinese social relations are social relations typified by a reciprocal social network.
 Often social obligations within the network are characterized in familial terms.
 The individual link within the social network is known by "guanxi" (关系/關係) and the feeling within the link is known by the term "ganqing" (感情).
 An important concept within Chinese social relations is the concept of face, as in many other Asian cultures.
 A Buddhist-related concept is "yuanfen" (缘分/緣分).
