The entities are often concepts of some sort, but they can be anything with a pattern of relationships. Proximities can be obtained from similarities, correlations, distances, conditional probabilities, or any other measure of the relationships among entities. Pathfinder networks are derived from proximities for pairs of entities. Network scaling represents another method based on graph theory. Data clustering and multidimensional scaling are two such methods. Several psychometric scaling methods start from proximity data and yield structures revealing the underlying organization of the data. Pathfinder networks are potentially applicable to any problem addressed by network theory. List of concept- and mind-mapping softwareĪ pathfinder network is a psychometric scaling method based on graph theory and used in the study of expertise, knowledge acquisition, knowledge engineering, scientific citation patterns, information retrieval, and data visualization.( March 2017) ( Learn how and when to remove this template message) Please help to improve this article by introducing more precise citations.
