Concept maps — the hidden gem of personal knowledge management
Facilitating associative thinking based on your permanent notes
In the world of personal knowledge management (PKM), there is an intense focus on note-taking, but hardly any focus on the structural organization of notes or how they relate to each other. Some tools have features for creating structure in your notes, but most tools do a rather poor job. The aim of this article is to convince you that concept mapping is the method you, as a serious PKM enthusiast, should master to structure your second brain.
Concept maps
A concept map is a visual representation of relationships between concepts. A concept map consists of nodes and edges where the nodes summarize concepts and the edges represent the relationship between the concepts. In the simplest form, concept maps consist of noun-verb relationships as shown below. This is the essence of knowledge graphs, which is a simpler form of concept maps.
In concept maps, you can in principle put anything on the nodes and you may color and shape code the nodes, link them by any statement, make one-to-many relationships, and much more. Here is a somewhat more complex example representing a broad selection of data-oriented tasks in data science (yes, I am a data scientist).
