collective leader behavior ratings by assessing the patterns of

connections that emerge in a team and providing a method for modeling both vertical and shared leadership

within a team


Social software - Social network analysis

1 Social network analysis tools analyze the data connection graphs within social

networks, and information flow across those networks, to identify groups (such as cliques or key influencers) and trends. They fall into two categories: professional research tools,

such as Mathematica, used by social scientists and statisticians, and consumer

tools, such as Wolfram Alpha which emphasise ease-of-use. See list at Social

network analysis software.


Computer and network surveillance - Social network analysis

1 government agencies such as the Defense Advanced Research Projects

Agency (DARPA), the National Security Agency (NSA), and the

Department of Homeland Security (DHS) are currently investing heavily in research involving social network

analysis



1 Jason Ethier of Northeastern University, in his study of modern social network analysis, said the following of the Scalable Social

Network Analysis Program developed by the Information Awareness Office:



1 The purpose of the SSNA algorithms program is to extend techniques of

social network analysis to assist with distinguishing potential terrorist cells from legitimate groups of people ..


Surveillance - Social network analysis

1 One common form of surveillance is to create maps of Social network analysis|social networks based on data from social networking sites such as Facebook, MySpace, Twitter as well as from

traffic analysis information from phone call records such as those in the NSA call database, and others. These social network maps are then

data mining|data mined to extract useful information such as personal interests,

friendships affiliations, wants, beliefs, thoughts, and activities.

Social network analysis software

1 'Social network analysis software' (SNA software) is software which facilitates quantitative analysis of

behavior|quantitative or qualitative research|qualitative analysis of social networks, by describing features of a network either through numerical or Graph drawing|visual representation.


Social network analysis software - Overview

1 Networks can consist of direct linkages between nodes or indirect linkages based upon shared attributes, shared attendance

at events, or common affiliations.Wasserman Faust, Social

Network Analysis Methods and Applications Network features can be at the level of

individual node (graph theory)|nodes, dyad (sociology)|dyads, triad (relationship)|triads,

ties and/or edges, or the entire network


Social network analysis

1 Social network analysis views social relationships in terms of network theory,

consisting of nodes (representing individual actors within the network) and ties (which

represent relationships between the individuals, such as friendship, kinship, organizations, sexual network|sexual

relationships, etc.) These networks are often depicted in a social network diagram, where nodes are represented as points and ties are

represented as lines.

money laundering and terrorism.


Social network analysis - Modelling and visualization of networks

1 Many of the Social network analysis software|analytic software have

modules for network visualization


Social network analysis - Modelling and visualization of networks

1 Especially when using social network analysis as a tool for facilitating change, different

approaches of participatory network mapping have proven useful. Here participants /

interviewers provide network data by actually mapping out the network (with pen and

paper or digitally) during the data collection session. One benefit of this approach is that it allows researchers to collect qualitative data

and ask clarifying questions while the network data is collected.


Social network analysis - Practical applications

1 In the private sector, businesses use social network analysis to support

activities such as customer interaction and analysis, marketing,

and business intelligence needs


Social network analysis - Practical applications

1 Social network analysis is also used in intelligence, counter-intelligence

and law enforcement activities

structure as a distinct analytical method and was articulated and
