or qualitative analysis of social networks, by describing features of a network either through numerical or visual representation.


Overview

Networks can consist of anything from families,
project team In a project, a project team or team is defined as "an interdependent collection of individuals who work together towards a common goal and who share responsibility for specific outcomes of their organizations". An additional requirement to the or ...
s,
classroom A classroom or schoolroom is a learning space in which both children and adults learn. Classrooms are found in educational institutions of all kinds, ranging from preschools to universities, and may also be found in other places where education ...
s,
sports team A sports team is a group of individuals who play sports (sports player), usually team sports, on the same team. The number of players in the group depends on type of the sports requirements. Historically, sports teams and the people who play ...
s,
legislature A legislature is an assembly with the authority to make law Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior,Robertson, ''Crimes against humanity'', 90. with its p ...
s,
nation-states A nation state is a political unit where the state and nation are congruent. It is a more precise concept than "country", since a country does not need to have a predominant ethnic group. A nation, in the sense of a common ethnicity, may i ...
,
disease vector In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes. The first major discovery of a disease vec ...
s, membership on networking websites like Twitter or Facebook, or even the Internet. Networks can consist of direct linkages between nodes or indirect linkages based upon shared attributes, shared attendance at events, or common affiliations. Network features can be at the level of individual
node In general, a node is a localized swelling (a "knot") or a point of intersection (a vertex). Node may refer to: In mathematics *Vertex (graph theory), a vertex in a mathematical graph *Vertex (geometry), a point where two or more curves, lines, ...
s,
dyad Dyad or dyade may refer to: Arts and entertainment * Dyad (music), a set of two notes or pitches * ''Dyad'' (novel), by Michael Brodsky, 1989 * ''Dyad'' (video game), 2012 * ''Dyad 1909'' and ''Dyad 1929'', ballets by Wayne McGregor Other uses ...
s, triads, ties and/or edges, or the entire network. For example, node-level features can include network phenomena such as
betweenness Betweenness is an algorithmic problem in order theory about ordering a collection of items subject to constraints that some items must be placed between others.. It has applications in bioinformatics. and was shown to be NP-complete by . Problem ...
and
centrality In graph theory and network analysis, indicators of centrality assign numbers or rankings to nodes within a graph corresponding to their network position. Applications include identifying the most influential person(s) in a social network, key ...
, or individual attributes such as age, sex, or income. SNA software generates these features from raw network data formatted in an edgelist, adjacency list, or
adjacency matrix In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case of a finite simp ...
(also called sociomatrix), often combined with (individual/node-level) attribute data. Though the majority of network analysis software uses a plain text ASCII data format, some software packages contain the capability to utilize relational databases to import and/or store network features.

s are important to understand network data and convey the result of the analysis. Visualization often also facilitates qualitative interpretation of network data. With respect to visualization, network analysis tools are used to change the layout, colors, size and other properties of the network representation. Some SNA software can perform
predictive analysis Predictive analytics encompasses a variety of statistical techniques from data mining, predictive modeling, and machine learning that analyze current and historical facts to make predictions about future or otherwise unknown events. In busines ...
. This includes using network phenomena such as a tie to predict individual level outcomes (often called peer influence or contagion modeling), using individual-level phenomena to predict network outcomes such as the formation of a tie/edge (often called homophily models) or particular type of triad, or using network phenomena to predict other network phenomena, such as using a triad formation at time 0 to predict tie formation at time 1.
