# Social Network Simulator SocialNetworkSimulator, A software that enable spatio-temporal social network analysis and simulation, is co-direcetd by Xinyue Ye at New Jersey Institute of Technology and Ming-Hsiang (Ming) Tsou at San Diego State University. This tool is based upon work supported by the National Science Foundation under Grant No. 1416509. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author and do not necessarily reflect the views of the National Science Foundation. Currently, social media has been playing an important role in the process of information diffusion. Exploring the pattern of message propagation on social network help us better prepare for natural disasters or human crises. So, we developed models, algorithms, and tools to generate simulated networks, analyze simulated networks, and simulate information diffusion on social network over time.

Below is the summary of the functions in the menu: | Menu | Description | |---|---| | **File**->Exit|Exit the software| | **Network**->Generate Single Simulated network | Generate a simulated network based on a single model.| | **Network**->Generate Complex Simulated network | Generate a complex network based on one or more network model. The complex network is constructed by adding edges among several smaller networks| | **Network**->Save Network | Save the current network as a txt file| | **Network**->Load Network | Load a network from a txt file| | **Analysis**->Network Analysis | Perform network analysis| | **Community**->CNM | Conduct community detection with CNM algorithm| | **Community**->GirvanNewman |Conduct community detection with GirvanNewman algorithm | | **Simulator**->User Level |Simulate information diffusion on the user level | | **Simulator**->City Level |Simulate information diffusion on the city level | | **Data** |Provide some functions to prepare the data used in the software| ## Example Let's generate a single simulated network use this software. After starting the software, the default window is for generating a single simulated network. If you are not on the interface, please choose Network->Generate Single Simulated Network to switch to the following window:  To generate a single network, please follow these steps: 1. Select a network model from the pull-down list. 2. After selecting a network model, the responding parameters will load automatically. Different network model has different set of parameters. Please configure all the parameters as the picture shows below:  3. Check **Base Map** to generate a network with a underlying base map (.shp file), or leave it unchecked to get a network without any base map. Check **Show Edge** or not to control if the network shows edges among nodes. You may get the similar network like below:
