Clinical guidelines as plans: An ontological theory
Clinical guidelines are special types of plans realized by collective agents. We provide an ontological theory of such plans that is designed to support the construction of a framework in which guideline-based information systems can be employed in the management of workflow in health care organizations.
The framework we propose allows us to represent in formal terms how clinical guidelines are realized through the actions of are realized through the actions of individuals organized into teams. We provide various levels of implementation representing different levels of conformity on the part of health care organizations.
Implementations built in conformity with our framework are marked by two dimensions of flexibility that are designed to make them more likely to be accepted by health care professionals than standard guideline-based management systems. They do justice to the fact 1) that responsibilities within a health care organization are widely shared, and 2) that health care professionals may on different occasions be non-compliant with guidelines for a variety of well justified reasons.
The advantage of the framework lies in its built-in flexibility, its sensitivity to clinical context, and its ability to use inference tools based on a robust ontology. One disadvantage lies in its complicated implementation
Physical Properties of Biological Entities: An Introduction to the Ontology of Physics for Biology
As biomedical investigators strive to integrate data and analyses across spatiotemporal scales and biomedical domains, they have recognized the benefits of formalizing languages and terminologies via computational ontologies. Although ontologies for biological entities—molecules, cells, organs—are well-established, there are no principled ontologies of physical properties—energies, volumes, flow rates—of those entities. In this paper, we introduce the Ontology of Physics for Biology (OPB), a reference ontology of classical physics designed for annotating biophysical content of growing repositories of biomedical datasets and analytical models. The OPB's semantic framework, traceable to James Clerk Maxwell, encompasses modern theories of system dynamics and thermodynamics, and is implemented as a computational ontology that references available upper ontologies. In this paper we focus on the OPB classes that are designed for annotating physical properties encoded in biomedical datasets and computational models, and we discuss how the OPB framework will facilitate biomedical knowledge integration
Translating Universal Scene Descriptions into Knowledge Graphs for Robotic Environment
Robots performing human-scale manipulation tasks require an extensive amount
of knowledge about their surroundings in order to perform their actions
competently and human-like. In this work, we investigate the use of virtual
reality technology as an implementation for robot environment modeling, and
present a technique for translating scene graphs into knowledge bases. To this
end, we take advantage of the Universal Scene Description (USD) format which is
an emerging standard for the authoring, visualization and simulation of complex
environments. We investigate the conversion of USD-based environment models
into Knowledge Graph (KG) representations that facilitate semantic querying and
integration with additional knowledge sources.Comment: 6 pages, 3 figures, ICRA 202
Towards a Conceptualization of Sociomaterial Entanglement
In knowledge representation, socio-technical systems can be modeled
as multiagent systems in which the local knowledge of each individual agent can
be seen as a context. In this paper we propose formal ontologies as a means to
describe the assumptions driving the construction of contexts as local theories and
to enable interoperability among them. In particular, we present two alternative
conceptualizations of the notion of sociomateriality (and entanglement), which
is central in the recent debates on socio-technical systems in the social sciences,
namely critical and agential realism.
We thus start by providing a model of entanglement according to the critical realist
view, representing it as a property of objects that are essentially dependent on
different modules of an already given ontology. We refine then our treatment by
proposing a taxonomy of sociomaterial entanglements that distinguishes between
ontological and epistemological entanglement. In the final section, we discuss the
second perspective, which is more challenging form the point of view of knowledge
representation, and we show that the very distinction of information into
modules can be at least in principle built out of the assumption of an entangled
reality

OntoEng: A design method for ontology engineering in information systems
This paper addresses the design problem relating to ontology engineering in the discipline of information systems. Ontology engineering is a realm that covers issues related to ontology development and use throughout its life span. Nowadays, ontology as a new innovation promises to improve the design, semantic integration, and utilization of information systems. Ontologies are the backbone of knowledge-based systems. In addition, they establish sharable and reusable common understanding of specific domains amongst people, information systems, and software agents. Notwithstanding, the ontology engineering literature does not provide adequate guidance on how to build, evaluate, and maintain ontologies. On the basis of the
gathered experience during the development of V4 Telecoms Business Model Ontology as well as the conducted integration of the related literature from the design science paradigm, this paper introduces OntoEng and its application as a novel systematic design
method for ontology engineering
B-Cube, Behavioural modelling of technical artefacts
A new model, B-Cube, is described for managing knowledge at the behaviour level of the function–behaviour–structure framework. The model proposes a three-dimensional approach to the behavioural modelling of technical artefacts using definitions based mainly on the meta-ontology DOLCE as concepts of behaviour.
The present work aims to show how these terms and those from the NIST functional basis can complement each other in functional design. It is assumed that this model achieves similar objectives with behaviours to those obtained by the NIST functional basis with functions, i.e. the representation of behaviours in CAD and KBS, a scheme for the modelling of behaviours and a universal set of behaviours. The modelling language IDEF was adapted to be able to produce a graphic example of the modelling of technical artefacts in the FBS framework using B-Cube terminology at the behaviour level
