A New Account of Abstraction?

Software engineering could benefit from a more rigorous grounding in epistemology, e.g., for the account of abstraction. So, let’s see what we can learn from: Raymond Turner (2018) Computational Artifacts Continue reading

Technical Artefacts and Software Requirements

The epistemic concept of “Technical Artefact” may prove useful for studying requirements engineering. It brings together the notions of the world as physical objects with the world of intentionally acting agents. Continue reading

Stachowiak on Preterition and Abundance in Modelling

In his 1973 book “Allgemeine Modelltheorie” Herbert Stachowiak discusses the concepts of Preterition, Abundance and Contrastation of Original-Model mappings. This can be interpreted using homomorphism preservation and other logical concepts. Continue reading
