Social Network Analysis & Visualization

Meerkat is an automated Social Network Analysis (SNA) tool used to analyze, visualize and interpret large or complex networks of information, allowing users to examine patterns and investigate relational dynamics.

The application uses information about the interactions between a set of objects (or nodes) within a network and lets the user employ different algorithms to automatically identify meaningful connections or highlight the most influential or central nodes in different ways.

Network analysis features include:

  • Automated community detection and analysis
  • Interactive visualization using general, community and metric-based layouts
  • Filtration and extraction of useful data
  • Dynamic analysis of network changes over time

Meerkat also provides tools for text mining, including polarity and emotion analysis, which give users the ability to examine text for positive and negative sentiments and a range of basic emotions. Meerkat ED, a version of the program that has been tailored specifically for educational environments, allows instructors to evaluate student activities in online discussion forums.
