Frequently Asked Questions
X+ Ontologies are the intelligence layer that makes Phenom AI accurate rather than approximate. Built on a decade of HR data including 1.1 billion candidate profiles, 400 million jobs, 200,000 skills, and 570,000 job titles, they map how skills, roles, and experience actually relate to each other.
This is what lets Phenom AI understand context rather than just match keywords.
Phenom's ontology understands that a nurse with ICU experience is relevant for a surgical coordinator role even if the job description uses different terminology. Keyword search cannot make that inference.
The ontology knows which skills transfer, which roles are adjacent, and which experience signals actually predict success. That produces better matches than surface-level text matching.
Yes. Every hiring decision, promotion, and departure in your organization feeds back into the ontology. The system learns what good looks like in your specific context, not just in the general market.
Over time, recommendations become more specific to your organization's patterns rather than relying only on broad industry data.
The ontology spans 400 million jobs, 1.1 billion candidate profiles, 200,000 skills, 570,000 job titles, 1.2 million companies, 270,000 schools, and 50 industries.
It was built over more than fifteen years specifically for HR rather than adapted from a general knowledge base. That depth is what makes the matching accurate across diverse roles and industries.
Ontologies underpin every agent. The Sourcing Agent draws on 1.1 billion profiles to find candidates. The Career Coach Agent maps skills to progression paths. The Voice Screening Agent understands which answers signal competency for a specific role.
Without the ontology, agents would be making decisions without context. The ontology is what makes their reasoning coherent.
