## Modelling with Classes: Square and Rectangle revisited

Classic problem in class-modelling: how to express that a square is a special kind of rectangle? In order to deepen understanding, let us scrutinize the situation a bit closer here, using logical/ structural foundations of modelling: Continue reading

## Reflections on Abstractions in Relational Structures. The very basic Setting.

Abstractional concepts can be found in the very basics of Graph Theory and Formal Concept Analysis. They provide the basic elements of Classification, Aggregation and Generalisation for a deeper rigorous analysis of Abstractions. Continue reading

## Reflections on Abstractions: Classification and Generalisation by Conceptualisation

It is demonstrated how the basic notion of Concept in Formal Concept Analysis covers two of the fundamental notions of Abstraction: Classification and Generalisation. This is why conceptualisation is so highly valuable in examining entities and their properties. Continue reading

## Reflections on Abstractions: Generalisation and Aggregation

Abstraction Awareness is about gaining a deeper understanding of abstraction. With basic means of Graph Theory we diff among two kinds of abstraction: abstraction wrt. generalisation and aggregation. Continue reading
