Social network analysis: 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.

Social network game: 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.

International Network for Social Network Analysis: The International Network for Social Network Analysis (INSNA) is a professional academic association of researchers and practitioners of social network analysis.

Social network: 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 (online game): Bananagrams is an online social game developed by Large Animal Games in partnership with Majesco Entertainment.  It launched on Facebook on November 17, 2008.

Social network aggregation: 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".

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).
