From Tokens to Knowledge: The Digital Backbone That Forms Context Graphs Shannon's 1948 communication theory bracketed meaning entirely: "semantic aspects of communication are irrelevant to the engineering problem." That boundary clarified what his theory measures. It also left a layer unmeasured. Consider the word TANK. One system sees a fish tank. Another sees an armored vehicle. Transmission succeeded. Interpretation diverged. This is not a corner case in language. It is the ordinary condition of real-world semantics: words routinely accumulate multiple senses, and the correct sense depends on surrounding cues. The bridge from data transfer to data understanding depends on the next layer up: the layer where systems decide which meaning a shared token should activate. Context Engineering is a systems discipline that treats context as a measurable gap between communicating and decision-making systems. A context graph shifts the meaning of a symbol from a flat label to a position inside a structure. "Tank" is not merely a string, but a node connected to neighbors that constrain interpretation: aquarium → water → fish versus armored vehicle → battlefield → platoon. Where Shannon measured noise in transmission, a context graph measures noise in interpretation. Ontology grounding and alignment convert ambiguous symbols into computable structures. Context telemetry turns meaning into an observable runtime signal, enabling safer AI agents, more reliable interoperability, and more defensible decisions in operational environments where ambiguity carries real costs. 🧠 Systems can make interpretation measurable when they externalize meaning into grounded graphs, quantify uncertainty over competing meanings, and expose interpretive divergence as telemetry with provenance. That does not replace Shannon's achievement. It extends his program into the domain he bracketed, where meaning becomes the next signal that engineering learns to measure.

ONTrust: A Reference Ontology of Trust Trust has stood out more than ever in the light of recent innovations. Some examples are advances in artificial intelligence that make machines more and more humanlike, and the introduction of decentralized technologies (e.g. blockchains), which creates new forms of (decentralized) trust. These new developments have the potential to improve the provision of products and services, as well as to contribute to individual and collective well-being. However, their adoption depends largely on trust. In order to build trustworthy systems, along with defining laws, regulations and proper governance models for new forms of trust, it is necessary to properly conceptualize trust, so that it can be understood both by humans and machines. This paper is the culmination of a long-term research program of providing a solid ontological foundation on trust, by creating reference conceptual models to support information modeling, automated reasoning, information integration and semantic interoperability tasks. To address this, a Reference Ontology of Trust (ONTrust) was developed, grounded on the Unified Foundational Ontology and specified in OntoUML, which has been applied in several initiatives. For example, to demonstrate how it can be used for: * Conceptual modeling and enterprise architecture design * Language evaluation and (re)design * Trust management * Requirements engineering, and for * Trustworthy AI in the context of affective Human-AI teaming ONTrust formally characterizes the concept of trust and its different types, describes the different factors that can influence trust, as well as explains how risk emerges from trust relations. To illustrate the working of ONTrust, the ontology is applied to model two case studies extracted from the literature.

LordAlex Leon, Wiseways’CTO, after the presentation of IEML that I made yesterday, had this reaction on LinkedIn : « Mind = Blown: The Future of Semantic Intelligence Delving into ontology and IEML (Information Economy Meta Language) alongside Pierre Lévy and the Wisewase team was an enlightening experience. Our technical dialogue swiftly transformed into a profound conversation, reshaping my outlook on the realm of possibilities. Pierre, a trailblazer in collective intelligence and semantic metadata (CEO & Co-founder at INTLEKT Metadata Inc.), unveiled IEML - a semantic code that mirrors natural language's expressiveness while retaining algebra's computability. Consider this: a universal, programmable language for meaning itself. The implications transcend AI: - Dynamic visualization of knowledge systems - Genuine semantic interoperability among systems - A computational approach to collective intelligence - Novel avenues for knowledge management and preservation From my vantage point bridging AI and business transformation, IEML emerges as a potential game-changer in structuring, sharing, and scaling human knowledge in the digital era. I urge all enthusiasts of AI's future, knowledge management, and semantic technologies to delve into Pierre's groundbreaking work. Explore his blog for captivating insights: intlekt.io Gratitude to Pierre Lévy for illuminating us with your vision and expertise.

Jayson Bursill, Delta's own well-known Data Scientist was recently honored with two awards from the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) including the YEA (Young Engineers in ASHRAE) Award of Individual Excellence and the Distinguished Service Award. Following the recognition, Jayson went on to be video interviewed by AutomatedBuildings.com's @KimonOnuma, where he shared valuable insights regarding the gap between BIM and operation control, BACnet, RDF, and the value of natural tagging in large language models (LLM). Jayson notably comments in the video, “We already crossed the line with PDFs. Now ASHRAE needs to provide tools that enhance access to its deep knowledge base—including the research that never makes it past a summary paragraph.” Watch the complete video interview on Vimeo: vimeo.com/1096198774/d2b9267… Jayson is part of ASHRAE’s new MTG on Generative AI and exploring how LLMs can unlock buried insight in technical documentation. #ASHRAE2025 #DigitalTwins #BIM #BACnet #RDF #AIinBuildings #LLMs #OpenStandards #GenerativeAI #SemanticInteroperability #MTGGenA

The Elephant in the Room? Not scalability. Not regulation. Not throughputs. Not Transactions per second. It’s Semantic Inter-operability. Everyone’s building bridges. But if consortium partners don’t UNDERSTAND each other, all we’re doing is moving ambiguity at high speed. Semantic interoperability is the GLUE of the digital economy. It’s what turns data into trust. Automation into assurance. Tokenomics into credibility. TradeLens. Everipedia. We Trade. Terra/Luna. All teach us one thing: When meaning fails, systems fail. When building Web3, DeFi, or Stablecoin, ask not: Do systems talk to each other? Ask: Do systems truly UNDERSTAND each other?
