RADIOMICSRadiomics Ontology

The Radiomics Ontology aims to cover the radiomics feature domain with a strong focus on first order, shape, textural radiomics features. In addition, in the original version. it includes classes about segmentation algorithms and imaging filters. Due to a recent collaboration with the IBSI (International Biomarkers Standardization Initiative), the ontology has been expanded (v 1.6) and it includes all the entities presented in the IBSI document. Therefore, a broad coverage of not only radiomics features, but also every entity (e.g.

SUMSOSustainable Meat Systems Ontology

The Sustainable Meat Systems Ontology (SuMSO) is a domain ontology addressing meat systems sustainability. It extends Sustainability Core Ontology (SCO) and Basic Formal Ontology (BFO). Currently, SuMSO provides a representation of the core architectural features of a sustainable meat system, focusing on cow-derived meat as an initial use case. SuMSO deals with meat in a broad sense: it contemplates the liaisons with other cow-derived materials, such as leather and bones., SuMSO is a domain of ontology, representing meat systems sustainability.

GDOGraphic Descriptor Ontology

The Graphic Descriptor Ontology (GDO) is intended for use in describing graphics that represent the form of objects. It uses the language of visual communication, illustration, and technical drawing. The GDO is rooted in the Basic Formal Ontology (BFO) and uses several classes from the Information Entity Ontology of the Common Core Ontologies as a mid-level ontology.

MENOMid-level Energy Ontology

The midlevel energy ontology (MENO) is a BFO-based midlevel ontology. It comprises the concepts for energy qualities, energy-based dispositions and energy-driven transformation and transfer processes and their interrelations. It has the goal to provide an upper level structure for these concepts for energy-related domain ontologies.

L'ontologia fondazionale della sostenibilità

SCO is a middle-level ontology, representing the major theoretical challenges to sustainability: 1) The polysemy of the term sustainability. 2) The relationship between sustainability and sustainable development. 3) The complexity underlying sustainability. SCO aims to play a pivotal role in harmonizing and integrating top-level and domain ontologies regarding sustainability.

EROExperimental Research Ontology (ERO)

The Experimental Research Ontology (ERO) is a small ontology that models some fundamental aspects of data creation in experimental research. ERO is aligned with several upper ontologies, including BFO, IAO, OBI, and SOSA. ERO enables the characterization of different types of experiments by specifying different methodologies and collections of parameters. Methodology specifications may include, e.g., research objectives, experiment setups and procedures, success criteria, or saftey regulations.

GFOGeneral Formal Ontology

The General Formal Ontology is a top-level ontology for conceptual modeling, which is being constantly further developed by Onto-Med. It includes elaborations of categories like objects, processes, time and space, properties, relations, roles, functions, facts, and situations. Moreover, we are working on an integration with the notion of levels of reality in order to more appropriately capture entities in the material, mental, and social areas.

OGMSOntology for General Medical Science

The Ontology for General Medical Science (OGMS) is an ontology of entities involved in a clinical encounter. OGMS includes very general terms that are used across medical disciplines, including: 'disease', 'disorder', 'disease course', 'diagnosis', 'patient', and 'healthcare provider'. OGMS uses the Basic Formal Ontology (BFO) as an upper-level ontology. The scope of OGMS is restricted to humans, but many terms can be applied to a variety of organisms.

SEMIOTICSA content ontology pattern that encodes a basic semiotic theory, by reusing the situation pattern.

A content ontology pattern that encodes a basic semiotic theory, by reusing the situation pattern. The basic classes are: Expression, Meaning, Reference (the semiotic triangle), LinguisticAct (for the pragmatics), and Agent. A linguistic act is said to be context for expressions, with their meanings and references, and agents involved. Based on this pattern, several specific linguistic acts, such as 'tagging', 'translating', 'defining', 'formalizing', etc. can be defined, so constituting a formal vocabulary for a pragmatic web.
