Descriere

  • Create and maintain procurement ontologies that define business entities, attributes, relationships, events, states, and concepts.
  • Own semantic models for suppliers, contracts, obligations, sourcing events, categories, risks, savings, and operational workflows.
  • Build and refine procurement knowledge graphs that capture entities, relationships, dependencies, events, and business context.
  • Establish context-graph patterns for users, workflows, retrieval systems, and AI agents.
  • Represent temporal relationships, lifecycle states, provenance, hierarchies, ownership, and dependencies.

  • Ensure semantic and graph models enable retrieval, reasoning, recommendations, workflow automation, and agentic execution.
