From the history of computation to knowledge representation
There are various tools that make computational problems easier to solve. Through thousands of years mankind built and refined them in order to grasp intricate operations that can help unravel the complexity of the world. History of those tools is connected with the ability to visualize, categorize and also to assign hierarchy to things and to define relations between them. Some of them have philosophical roots, other could be employed only when suitable and sufficient mathematical apparatus became available. This paper shows a path, beginning with simple tools that aided simple mathematical operations through the ones that allowed visualization of relations between things, and finally, to the combination of these two kinds, which resulted gave us the beginning of modern ontologies in the context of informatics.
