Ontology competition

This year’s contest is around ontologies that connect to the physical world in a quantitative way.

Extended submission deadline: June 29th

The goal is to offer approaches to subjects that are of broad relevance across the physical sciences and technology that can be applied to realistically complex problems, and demonstrate how they work for representing and querying data.

Examples of subjects that would be of interest are:

1. Spatially varying qualities such as temperature, wind speed, precipitation as it varies over an extended region as used in climate work, engineering models that measure spatial patterns of stress in materials, patterns of population and related aspects such as travel patterns and infrastructure, relevant for urban planning or study of epidemics, or distributions of substances or cells in the body as they evolve.

2. System of physical quantities – the question of units and conversions between them, physical laws and formulas that relate them, “base” versus “derived” quantities, dimensionless quantities, quantities that vary in time.

3. Temporal evolution and patterns: Time course of disease, markets, dynamics of physical processes, longitudinal studies, treatment and clinical follow-up.


  • The ontology should be represented using OWL or Common logic, specifying a reasoner for the fragment of logic used.
  • A representative data set (which can be simulated) that is sufficient to demonstrate utility.
  • A set of queries demonstrating expressiveness and utility and which produce expected results.

Submissions will be in the form of a short paper giving an explanation of the approach and instructions for demonstrating the work. The submitter should document any software that needs to be installed, as well as step by step instructions for executing the queries. Reviewers will follow these instructions and reproducibility will be part of the evaluation. Packaging that requires minimal installation, such as by a self-contained system that uses docker, would be beneficial.

Submitted papers should not exceed 5 pages (not including instructions) and include an abstract of no more than 300 words. Papers should be submitted non-anonymously in PDF format following IOS Press formatting guidelines. Accepted submissions will be published in the JOWO proceedings.

The winner of the competition will receive a prize of $500 USD or equivalent.

All material should be publicly available, for example via a Github repository, clearly licensed and accompanied by a descriptive Readme.

Evaluation criteria
– How realistic are the use case and data?
– Expressive power
– Range of applicability – is the work useful across different domains
– Efficiency and scaling
– Conformity to one or more upper level ontologies
– Ease of reproducing the query results
