Computer Programs for Social Network Analysis

Programs that convert data from one format into a different format

• Adj2Neg, a program for converting adjacency matrices to NEGOPY-style data in which there is one line of data per link. Each line begins with two ID numbers, telling who the link is from and who it goes to, followed by some values that describe the link (eg. strength, duration, content, channel, time, place, etc...) Besides making the data available for NEGOPY, this makes it much easier to work the data and reduces the number of errors that are inadvertently introduced when attempting to edit the data, especially for larger networks.
  
  
• Neg2Adj, a program for converting NEGOPY-style data into adjacency matrices for input to UCINET and other programs that require that format. Accepts up to 2,000 nodes and 60,000 links.
  
  
• Free2Fix, a program that parses and converts free-format files into fixed-format files for MultiNet and other programs that require a fixed format.

Programs for collecting network data

Programs for analysing networks

• AGD a broad range of existing algorithms for two-dimensional graph drawing and tools for implementing new algorithms. It is a product of a cooperation of groups in Halle, Köln, Saarbrücken, and Wien, and originated from the DFG-funded project "Design, Analysis, Implementation, and Evaluation of Graph Drawing Algorithms" in 1995-2000. Currently, AGD is further developed by the groups in Köln and Wien. more

• Apache Agora, by Stefano Mazzocchi. I'm a visual type of guy. I love to see things, I love to visualize them, hopefully in esthetically pleasant ways. I'm also fascinated by human dynamics and sociology. For these reasons, I started about the shape of a virtual community and if it was possible to come up with ways to harvest the data as transparently as possible about communities of invididuals and how to visualize this incredible amount of information so that it can yield insights that were hard to see before. I opted for a run-time interactive molecular-style simulation where a simple model describes the behavior of a single molecule (the person, in our case) and how it interacts with others in the same environment.

• DyNet, from Advanced Technology Assessment. ATA's dynamic network software package provides tools for creating data-driven visualizations of the underlying relational structures which would otherwise be obscured by the fragmentation of data into heterogeneous domains and databases. This program owes its original position in part to its GraphVista components, which simultaneously meet different demands from dynamic and static network visualization, as well as network analysis, with a valuable potential for graph browsing..
• Ecosystem Network Analysis a collection of quantitative methods that systematically teases most pertinent information from the full, complicated network description. In tracing the trophic connections among the populations of even the simplest ecosystems, the emerging picture soon comes to resemble a hopeless jumble, sometimes referred to as a "bird's nest" or "spaghetti" diagram. Yet within such a depiction lie valuable clues to how the ecosystem is functioning. "Ecosystem network analysis" is the rubric applied to a collection of quantitative methods that systematically teases most pertinent information from the full, complicated network description.

• LinkaLyzer™, from MDLogix, Inc, accepts as input your existing egocentric social network data in an SPSS, Microsoft® Excel, or tab-delimited text file. The data can be in either Egocentric (one record per Primary subject) or Egocentric-Dyadic (one record for each Secondary subject) format. LinkaLyzer lets you choose the criteria used to determine whether different subjects in your data are really the same person. You can define combinations of numeric, string, and date variables to be used with a variety of comparison functions to find potentially matching subjects in your data. Once you have produced a set of potential matches, you can view and accept them one by one, or for large datasets you can have LinkaLyzer accept all of them automatically. When the matches are combined, the links of matched subjects are also combined, resulting in a new network.
