While mind maps tremendously lack horizontal cross-connections, concept mapping inherents this feature as its core strength. It focuses on representing the relationships between concepts by using arrows. These arrows are usually annotated with a verb that explicitly defines the relationship. In this manner, the connections can be read as simple sentences, e.g. [Concept Maps] –have–> [network structure].
Although these labels clearly illustrate the nature of the individual connections, the networks can also quickly become confusing in the process of growing. The graphical, intuitive representation of a topic is therefore restricted, and it is re-verbalized with the consequence that the creative flow of ideas can break off. Moreover, the networks lack any hierarchy, which makes identifying a higher-level structure very difficult.
