Knowledge Graph Architecture and AI Enablement

• Support the design, implementation, and optimization of knowledge graph capabilities leveraging Graphwise Graph Modeling, GraphDB, GraphRAG, semantic standards, and human-in-the-loop validation practices. Partner with AI architects, engineers, product leaders, and other stakeholders to ensure knowledge assets are structured and governed for effective use in search, retrieval, recommendation, personalization, and emerging AI-enabled applications. Contribute to the ongoing evolution of semantic AI capabilities by applying technical expertise, evaluating solution performance, and recommending improvements that strengthen knowledge graph usability and business value.

Cross-Functional Architecture Leadership

• Provide technical guidance and collaborate with content, product, technology, UX, and data stakeholders to support effective knowledge architecture practices. Inform platform requirements, content architecture, integration approaches, and semantic technology decisions to support cross-functional initiatives and business objectives. Translate taxonomy, ontology, metadata, and knowledge graph concepts into clear recommendations that help teams implement consistent, scalable, and user-centered solutions.

Data Integration, Classification, and Semantic Governance

• Support and guide the evaluation, normalization, mapping, classification, and integration of internal and third-party knowledge assets. Apply and help improve governance processes that incorporate human-in-the-loop review to validate automated tagging, ontology expansion, content classification, and semantic enrichment activities. Ensure consistency, interoperability, and quality across content and data sources through hands-on analysis, documentation, stakeholder collaboration, and adherence to established governance practices.

Performance Optimization and Continuous Improvement

• Analyze knowledge platform analytics, search behavior, retrieval performance, and content utilization trends to identify opportunities for improving discoverability, relevance, taxonomy effectiveness, and knowledge architecture maturity. Recommend practical enhancements to taxonomy, ontology, metadata, and knowledge graph structures based on performance data, stakeholder feedback, and evolving business needs.

Knowledge Architecture Governance and Organizational Capability Development

• Serve as a senior technical resource on taxonomy, ontology, knowledge graphs, semantic technologies, Graphwise Graph Modeling, GraphDB, and human-in-the-loop knowledge engineering practices. Provide guidance, documentation, and knowledge-sharing support to stakeholders to promote consistent use of knowledge architecture standards and practices. Contribute input on relevant tools, technologies, and industry practices, and recommend improvements that support ISACA’s knowledge architecture maturity and AI-enabled capabilities.
