RefViz uses a word-based statistical analysis to determine which terms (referred to as keywords) in the title and abstract (or notes if there is no abstract) fields represent the main concepts or themes for a set of references. The Matrix visualization illustrates and highlights associations between keywords and groups, or among the keywords themselves. Associations between keywords and groups provide a global perspective of the concepts discussed across groups. Associations between keywords tell you which topics tend to be discussed together in the literature. The colour of each cell represents the relevance, or strength, of the associations.
Use the Matrix visualization to gain the following insights:
A. Obtain an at-a-glance overview of the major concepts discussed across groups
B. Review which subjects tend to be discussed together in the literature
C. Understand the overlap and associations between concepts
