OWL formalization of the Zachman Framework

'The Zachman Framework for Enterprise Architecture' (a.k.a. 'The Enterprise Ontology') defines an arrangement of concepts for describing an enterprise. The framework is, for example, used as reference in business analysis practices to capture the various perspectives required for enterprise modelling. Although known as 'The Enterprise Ontology', some people argue that the Zachman Framework is not an ontology as such. We’re not going to get into this debate here and prefer to look at it as being a 'lightweight' ontology, i.e., a ... Read more

A starter ontology for Value Stream Mapping

Value stream mapping is a lean management technique typically used in manufacturing business process re-engineering, but is equally suited for other kinds of business process improvement initiatives. The approach is deployed for assessing the current states of processes and practices and proposing improved future states. The following steps are generally tackled in order to successfully complete the approach: A suitable product family candidate is identified by analysing product quantities and routings. The takt time is calculated and a current ... Read more

Ten things to watch out for in ontology papers

Introduction A quick search in your favourite search engine is likely to reveal the extent of journal articles, conference papers and whitepapers that talk about the application of knowledge engineering and ontologies across various fields of study. In this post we’ll talk about 10 important points to watch out for in papers that deal with applied ontology principles. Referring to these points can prove handy when writing an ontology paper or when making a triage of several papers, for instance, to ... Read more

Core skills for the knowledge engineer

Introduction In this post we'll discuss some of the essential skills necessary for an individual to thrive in the role of knowledge engineer. Note that we'll be using the terms knowledge engineer, knowledge architect and ontologist interchangeably for simplicity. We are assuming that these roles all require expertise in developing technical ontologies using formal knowledge representation languages like the Web Ontology Language (OWL). Technical know-how The knowledge engineer should have technical know-how and full user-level understanding of computer-based ontology development tools. Very ... Read more

Building blocks of an ontology-driven system

There is an enormous amount of literature out there that investigates and documents ontology-related work. The literature remains very technical, highly specialised and somewhat overwhelming. This means that it is not easy for non-experts to understand what is actually required at a high level when contemplating a functional ontology-driven system. In this post, we’ll be looking at the building blocks that feed into the ‘minimum’ ontology-driven system from which benefits can be gained. The diagram in this post summarizes these essential building ... Read more

Ontoweave at a glance

Greetings and welcome to Ontoweave! After a couple of months of solid work to get my website assets together, I'm really pleased to announce that Ontoweave is now up and running. In this post, we'll talk a little bit about Ontoweave - its purpose, that field of knowledge being targeted and what my plans are in order to address it. To date, our information systems are still relying on data and information models as structures for organizing information, which we can tap ... Read more
