Description
Do you love to build ontologies?
Are you passionate about semantic information systems?
If so, we're looking for someone like you to join our team at APL.We are seeking an ontologist. As a member of our team, you'll contribute to ontologies in a variety of domains. You will be joining a hardworking team of engineers and scientists who craft and implement novel methods for solving meaningful national security challenges. We are passionate about applying knowledge representation techniques to draw insights from and enable computational analysis of large sets of structured and unstructured data.
As an Ontologist- Your primary responsibility will be to build ontologies.
- You will engage stakeholders to determine ontology requirements
- You will work with subject matter experts to craft ontology content.
- You will contribute to quality assurance and validation practices.
Qualifications
You meet our minimum qualifications for the job if you...- Possess a PhD degree in a field related to Applied Ontology (e.g. Philosophy, Computer Science, Cognitive Science, Mathematics, Logic, or Linguistics)
- Are proficient with Web Ontology Language (OWL2), Resource Description Framework Schema (RDFs), and Resource Description Framework (RDF)
- Are proficient with SPARQL
- Have a proven track record of conducting independent research within the field of ontology and knowledge representation
- Have excellent written and oral communication skills, and the ability to work with a wide range of collaborators
- Have experience building domain ontologies
- Are proficient with ontology editors (e.g., TopBraid Composer, Protégé)
- Have experience with formal representations of logical reasoning and inference
- Have experience eliciting, defining, and communicating modeling requirements for domain before crafting ontologies that meet those requirements
- Have experience with multi- or intra-disciplinary collaboration.
- Are able to obtain a Top Secret security clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.
You'll exceed our minimum requirements if you have...- A Doctorate degree in a field related to Applied Ontology (e.g. Philosophy, Computer Science, Cognitive Science, Mathematics, Logic, or Linguistics)
- Experience working with a software engineering team to deliver ontology-driven software features
- Experience building domain ontologies based on a top-level ontology
- Comfort with weighing tradeoffs between semantic expressivity and project-specific implementation strategies
- Experience with any of the following: Basic Formal Ontology (BFO); The Common Core Ontologies (CCO); W3C standards such as SOSA/SSN and the Time Ontology; ontologies in the Open Biological and Biomedical (OBO) Foundry; as well as other semantic web standards, such as Dublin Core, SKOS, QUDT, and GeoSPARQL
- Experience with triple stores or graph databases (e.g., GraphDB, Stardog, Jena Fuseki)
- Experience with semantic software packages and frameworks (e.g., Jena, Sesame, RDF4J, RDFLib)
- Experience with semantic validation languages (e.g. SHACL, SPIN)
- Experience with software version management using GIT
- Experience with Python
- Experience applying ontologies in natural language processing, image processing, or in the normalization/integration of heterogeneous data sources.
- Coursework in data structures, databases, metaphysics, knowledge representation, algorithms, mathematical logic, mereotopology, or software programming.
