Springer, Cham.978-3-030-79976-2http://hdl.handle.net/10400.26/37110Human Relativism (HR) was presented a decade ago as a new philosophical stance for thinking and modelling Information Systems. The Normative Approach for Modelling Information Systems (NOMIS) adopted HR by using a human-observable-action centred perspective of information systems. By using HR, NOMIS claims to have reduced unpredictability, attributed to human behaviour, and increased precision, required by formal methods. Still, there are other approaches, some of them using formal methods, supported by different ontologies, such as the well-known Bunge–Wand–Weber ontology, that lack the necessary precision. In this paper, we explore different ontologies, their relationship to language and why they fail to deliver precision. Precision, a concept introduced in HR, as a basis for engineering, is analysed, and the way to achieve it is proposed through suggesting guidelines for further discussion and research.engOntologyHuman RelativismEnterprise OntologyBWW OntologySemioticsInformation SystemsInformation Systems ModellingPrecision in Information Systems Modellingbook parthttps://doi.org/10.1007/978-3-030-79976-2_15
