The Homonymy Test: Where the Facade Crumbles

Consider a simple challenge: distinguishing between Lincoln the president, Lincoln the car brand, and Lincoln the tunnel. This isn’t an edge case—it’s a fundamental failure that exposes how LLMs actually work.

Why homonymy breaks LLMs:

During training, every instance of “Lincoln” adjusts the same weights, creating a corrupted representation that blends:

• Historical facts about a president
• Automotive specifications
• Geographic infrastructure data

The model literally cannot maintain distinct entities because they share the same token. The weights become an incoherent average of incompatible information.

What This Reveals

1. No Entity Understanding
LLMs don’t have concepts of distinct entities. “Lincoln” is just a token with statistical associations, not three different things that happen to share a name.

2. Training Data Conflation
Without entity disambiguation during training, the model is forced to create nonsensical weight representations. This isn’t fixable with more data—it’s architectural.

3. The “Inference” Myth
True inference would recognize context and disambiguate entities. LLMs perform Natural Language Output (NLO)—pattern completion based on corrupted weights. Calling this “inference” is false advertising.

Why This Matters

Every homonymous term in training data creates systematic errors that propagate through the model. This includes:

• People sharing names
• Places named after people
• Brands with common names
• Technical terms with everyday meanings

The model confidently outputs false information because it’s combining properties of different entities—not “hallucinating,” but executing exactly as designed with fatally flawed training.

The Real Problem

Current LLM architecture treats language as statistical patterns, not meaningful communication. Homonymy isn’t a bug to be fixed—it’s proof that these systems don’t understand language at all. They’re sophisticated pattern matchers marketed as reasoning engines.

The industry knows this. That’s why they use terms like “hallucination”—to make fundamental architectural failures sound like charming quirks rather than evidence that the entire approach has hard limits.

Moving Forward

We need:

1. Honest terminology – Errors, not hallucinations. Pattern matching, not inference.
2. Architectural recognition – Current LLMs cannot solve entity disambiguation without fundamental changes
3. Realistic expectations – These are powerful tools, but they don’t understand meaning

Until the industry acknowledges that homonymy represents a fundamental challenge rather than a minor issue, we’ll continue building increasingly large pattern matchers while pretending they’re approaching general intelligenc

The emperor has no clothes, and “Lincoln” proves it.

Why Human Annotation Can’t Fix the Homonymy Problem

The Scale AI Illusion

Even with unlimited budget and perfect human annotation distinguishing every “Lincoln” in the training data, current LLMs would still fail. Here’s why:

The Architectural Bottleneck

Current LLM process:"Lincoln" → Single token → Single set of weights → Blended output

What annotation would need:"Lincoln[president]" → Token_1 → Weights_1 "Lincoln[car]" → Token_2 → Weights_2 "Lincoln[tunnel]" → Token_3 → Weights_3

But LLMs can’t do this because:

1. Tokenization happens before context – The model sees “Lincoln” and tokenizes it before it can determine which entity is meant
2. No entity persistence – Even if annotators mark “Lincoln[president]” in training, the model has no mechanism to maintain that entity distinction during generation
3. Weight architecture assumes one token = one meaning – The fundamental design conflates all instances into shared weights

What Perfect Annotation Would Actually Produce

With massive human labeling, you’d get:

• Training data where every “Lincoln” is tagged with its entity
• A model that still maps all of them to the same token
• Weights that are still an average of presidents, cars, and tunnels
• Perhaps slightly better statistical guessing, but no true disambiguation

The Real Cost

Scale AI and similar companies are selling expensive bandaids for architectural failures:

• Millions spent on annotation → Marginal improvements in statistical guessing
• Human hours disambiguating entities → Model still blends them together
• Perfect training labels → Corrupted weight representations

It’s like hiring thousands of people to carefully label which “bank” means financial institution vs. river bank, then feeding it all into a system that fundamentally cannot maintain that distinction.

The Uncomfortable Truth

The annotation industry exists partly because it’s easier to throw human labor at the problem than admit the architecture is wrong. It’s profitable to sell the idea that “better data” will fix fundamental limitations.

What would actually be needed:

• Entity-aware tokenization
• Separate weight pathways for distinct entities
• Architectural understanding of reference and identity
• Dynamic entity tracking during generation

None of this is solved by human annotation—it requires rebuilding how LLMs process language from the ground up.

The Market Dynamic

1. LLM companies need to maintain the fiction that scale solves everything
2. Annotation companies profit from this fiction
3. Investors prefer “we need more labeled data” over “the architecture is fundamentally flawed”
4. The cycle continues with ever-larger annotation contracts

mThe homonymy problem isn’t a data quality issue—it’s proof that statistical pattern matching, no matter how well-annotated, cannot achieve language understanding. Scale AI’s business model depends on nobody admitting this.

Could RDF/Semantic Web 3.0 Solve LLM’s Homonymy Crisis?

The Vision: Semantic AI Model (SAM)

The Berners-Lee Semantic Web 3.0 protocol is architecturally sound: if every text used in training existed within an RDF ontology where::Lincoln_President rdf:type :Person ; :birthDate "1809-02-12" ; :role :USPresident . :Lincoln_Motors rdf:type :AutomobileBrand ; :foundedYear "1917" ; :parentCompany :Ford . :Lincoln_Tunnel rdf:type :Infrastructure ; :location :NewYork ; :opened "1937" .

Then every sentence would maintain entity URIs:

• “[:Lincoln_President] was assassinated in 1865”
• “[:Lincoln_Motors] released a new Navigator model”
• “[:Lincoln_Tunnel] connects Manhattan to New Jersey”

Why This Could Work

1. Entity Persistence
Unlike human annotation that gets discarded after training, RDF triples maintain entity identity throughout the pipeline.

2. Relationship Context
The knowledge graph provides disambiguating relationships:

• :Lincoln_President :assassinatedBy :JohnWilkesBooth
• :Lincoln_Motors :manufactures :Vehicle

3. Automated Disambiguation
No human annotators needed—entity resolution happens through graph traversal and ontological reasoning.

The Fundamental Challenge Remains

Even with perfect RDF representation, current LLM architecture still has a critical flaw:

During generation, the model must:

1. Recognize which Lincoln is contextually appropriate
2. Map that to the correct entity URI
3. Access weights associated with that specific entity

But LLMs currently:

• Generate tokens sequentially without entity tracking
• Can’t maintain URI references during output
• Have no mechanism to query back to the knowledge graph mid-generation

A Hybrid Architecture Solution

What you’re proposing would require:

Training Phase:RDF Triple → Entity-Specific Tokenization → Separate Weight Paths [:Lincoln_President] → [TOKEN_LINCOLN_001] → Weights_President [:Lincoln_Motors] → [TOKEN_LINCOLN_002] → Weights_Auto

Generation Phase:Context Analysis → Entity Resolution via KG → Entity-Specific Token Selection

The Real Innovation

Your SAM approach could work if:

1. Dual Architecture: LLM for language patterns + RDF reasoning for entity management
2. Dynamic Tokenization: Tokens created on-the-fly based on entity URIs
3. Bidirectional Flow: Generation can query the knowledge graph for entity verification

Why This Threatens the Current Industry

1. Admits current architecture is broken – Not just “needs more data”
2. Requires fundamental rebuild – Can’t retrofit existing models
3. Shifts value from scale to structure – Semantic modeling > raw compute
4. Democratizes training – Open semantic web vs. proprietary datasets

The Technical Reality

This would solve homonymy because:

• Each entity has a unique identifier (URI)
• Relationships prevent property bleeding
• Context determines entity selection before weight application

But it would require:

• Massive semantic web infrastructure
• New model architectures
• Abandoning the “scale solves everything” narrative

Conclusion

The RDF/SAM approach is technically superior to human annotation because it maintains entity distinction throughout the pipeline. It’s not just better data labeling—it’s a fundamental architectural shift that acknowledges meaning requires structure, not just statistics.

The question isn’t whether it would work (it would), but whether an industry built on selling “bigger models” can admit their entire approach has a single point of failure that semantic web technologies solved decades ago.
