Emeka Okoye

Semantic technologies permit powerful connections across a variety of linked data resources across the web. Until recently, developers had to learn the RDF language to discover and use these resources.

Leveraging the new Model Context Protocol (MCP) and LLM-powered natural-language interfaces, Emeka Okoye has created the RDF Explorer, an MCP service that lets any developer surf the semantic web without having to learn its specialized language.

We talked about:

his long history in knowledge engineering and AI agents
his deep involvement in the business and technology communities in Nigeria, including founding the country's first internet startup
how he was building knowledge graphs before Google coined the term
an overview of MCP, the Model Context Protocol, and its benefits
the RDF Explorer MCP server he has developed
how the MCP protocol and helps ease some of the challenges that semantic web developers have traditionally faced
the capabilities of his RDF Explorer:

facilitating communication between AI applications, language models, and RDF data
enabling graph exploration and graph data analysis via SPARQL queries
browsing, accessing, and evaluating linked-open-data RDF resources


the origins of RDF Explorer in his attempt to improve ontology engineering tooling
his objections to "vibe ontology" creation
the ability of RDF Explorer to let non-RDF developers users access knowledge graph data
how accessing knowledge graph data addresses the problem of the static nature of the data in language models
the natural connections he sees between neural network AI and symbolic AI like knowledge graphs, and the tech tribalism he sees in the broader AI world that prevents others from seeing them
how the ability of LLMs to predict likely language isn't true intelligence or actual knowledge
some of the lessons he learned by building the RDF Explorer, e.g., how the MCP protocol removes a lot of the complexity in building hybrid AI solutions
how MCP helps him validate the ontologies he creates

Podcast intro transcript
This is the Knowledge Graph Insights podcast, episode number 36. The widespread adoption of semantic technologies has created a variety of linked data resources on the web. Until recently, you had to learn semantic tools to access that data. The arrival of LLMs, with their conversational interfaces and ability to translate natural language into knowledge graph queries,
