       socnetv -V | --version

DESCRIPTION

       Social Network Visualiser (SocNetV) is a cross-platform, user-friendly application for the
       analysis and visualization of Social Networks.

       With SocNetV you can:

       • Draw social networks with a few clicks on a virtual canvas, load field data from a  file
         in  a  supported  format  (GraphML, GraphViz, EdgeList, GML, Adjacency, Edgelist, Pajek,
         UCINET, etc.) or crawl the internet to create a social network of connected webpages.

       • Edit  actors  and  ties  through  point-and-click,  analyse  graph  and  social  network
         properties,  produce  beautiful  HTML  reports  and  embed  visualization layouts to the
         network.

FEATURES

       These are the main features and routines of SocNetV:

       • Standard graph-theoretic and  network  cohesion  metrics,  such  as  density,  diameter,
         geodesics  and  distances,  connectedness,  eccentricity, clustering coefficient, walks,
         etc.

       • Matrix routines: Adjacency plot, Laplacian matrix, Degree matrix, Cocitation, etc.

       • Advanced structural measures for social network analysis such as centrality and prestige
         indices  (i.e. eigenvector and closeness centrality, betweenness centrality, information
         centrality, power centrality, proximity and pagerank prestige),

       • Community detection algorithms such as triad census, clique census, etc.

       • Structural equivalence analysis, using hierarchical clustering, actor  similarities  and
         tie profile dissimilarities, pearson coefficients, etc.

       • Random  network  creation,  i.e.  Erdos-Renyi, Watts-Strogatz, scale-free, ring lattice,
         etc.

       • One-click recreation of well-known social network datasets such as Padgett's  Florentine
         families.

       • Layout  algorithms  based  on  either prominence indices (i.e. circular, level and nodal
         sizes by centrality score) or force-directed models (i.e.  Eades,  Fruchterman-Reingold,
         etc) for meaningful visualizations of your social network data.

       • Multirelational  loading  and  editing.  You  can  load a network consisting of multiple
         relations or create a network on your own and add multiple relations to it.

       • Built-in web crawler, allowing you to automatically create networks from links found  in
         a given initial URL.

       • Comprehensive  documentation,  both  online  and  while  running  the application, which
         explains each feature and algorithm of SocNetV in detail.

       • Binary packages for Windows, Linux and MacOS.

OPTIONS

       --version | -V
              Displays the version of the program.

       --help | -H
              Displays a short help message.

       file.net
              The name of the file you want to open.

USAGE

       SocNetV  has  a  simple  Graphical  User  Interface (GUI). The biggest (right) part of the
       window is occupied by a virtual "canvas" where network nodes and edges appear. To the left
       of  it,  there  is  a dock with 4 buttons (add/remove node, add/remove link) and some LCDs
       which display statistics. On the top of the window,  you  will  find  the  menu  with  all
       commands and options, and at the bottom there is a status bar, where messages appear.

       To  create  a  new  node,  you  can  double-click on the canvas or click on the "add node"
       button.

       To create a new link, you can middle-click on the source node and then on the target node.
       Alternatively, you can click on the "add link" button from the dock.

       You  move  a  node  by  left-clicking  and  dragging it. When you right-click on a node, a
       context menu appears. From there you can remove the node, change its color, label, size as
       well  as  its  shape. SocNetV supports many kinds of node shapes, i.e rectangles, diamond,
       ellipse, circle, etc. A similar menu  appears when you right click on a link.

Supported Formats

       The default file format for reading and saving social network  is  GraphML.  Nevertheless,
       SocNetV can import various other formats (see below).

       You can load GraphML files by clicking on menu File > Load. To load other network formats,
       use the menu File -> Import.

       SocNetV supports the following network data formats:

       • GraphML (.graphml or .xml)

       • GML (.gml or .xml)

       • GraphViz (.dot)

       • Adjacency matrix (.sm, .adj or .csv )

       • Pajek (.net, .paj or .pajek),

       • UCINET's Data Language (.dl)

       • edge list (.lst or .list)

       • Weighted Lists (.wlst or .wlist)

Layout algorithms

       SocNetV also supports a variety of layout algorithms, such as spring-embedder (i.e. energy
       based)  and  centralities-based.  The  latter reposition all nodes in circles of different
       radiuses (i.e. more central nodes appear near the centre of the canvas) or  in  levels  of
       different height (more central nodes appear near to the top).

       You  can  apply layout algorithms from the menu Layout or by clicking on the checkboxes on
       the dock. Not all layouts appear on the dock, though.

KNOWN BUGS

       The network file parser is not  100%  trustworthy.  For  instance,  complicated  Pajek  or
       GraphML files can crash the application.

       Antialiasing  is  on by default. This slows down the application when the network has many
       nodes and edges. You can disable antialiasing by pressing F8 .
