Abstract

Tim Berners-Lee's Semantic Web vision (1999-2001) proposed machine-readable meaning as the next layer of internet infrastructure. Twenty-five years later, that vision has been realized — but not as Berners-Lee imagined. Knowledge graphs power Google Search, Wikidata feeds AI systems, and semantic markup structures how information is retrieved and synthesized. What the original vision lacked was a political economy: who builds the ontologies, who owns the knowledge graphs, who extracts rent from semantic infrastructure, and what happens when extraction exceeds replenishment. This paper bridges technical semantic infrastructure (RDF, OWL, SHACL, knowledge graphs) with the semantic economy framework (semantic labor, semantic capital, semantic liquidation), showing that the economic categories are not metaphorical but describe the actual dynamics of contemporary semantic systems.

Why This Matters Now

Four developments make this framework urgent. First, AI summarization systems (Google's AI Overviews, ChatGPT, Perplexity) increasingly mediate how knowledge reaches users — and these systems draw heavily on semantic infrastructure they did not build. Second, platform enclosure of open knowledge is accelerating: Wikidata's CC0 license enables extraction without attribution or compensation, and major AI companies have already ingested its contents into proprietary systems. Third, empirical evidence of semantic exhaustion is emerging — model collapse from training on synthetic data, knowledge graph incompleteness despite massive volunteer effort, contributor burnout from "usage invisibility." Fourth, no accounting framework currently exists for tracking these dynamics. The semantic economy framework provides one.

1. The Original Vision and Its Blind Spot

In 2001, Tim Berners-Lee, James Hendler, and Ora Lassila published "The Semantic Web" in Scientific American, outlining a vision of machine-readable meaning:

"The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation."

The technical stack they proposed — RDF (Resource Description Framework), OWL (Web Ontology Language), ontologies, inference engines — has largely been built. Google's Knowledge Graph contains billions of entities. Wikidata houses over 100 million concepts with 10 billion properties and relationships. Schema.org provides vocabulary for structured data across the web. SPARQL enables queries across linked datasets.

What Berners-Lee did not theorize was the political economy of this infrastructure:

Who performs the labor of building ontologies?
Who captures value from knowledge graphs?
What happens to the volunteer labor that populates Wikidata when Google ingests it?
How do platforms extract rent from semantic infrastructure they did not build?

Berners-Lee himself recognized the risk. In 2004, he warned that "corporations and political parties find it easy to create strangleholds on records and news. Then they can control what people believe." But his framework provided no accounting categories for tracking this dynamic.

The semantic economy framework provides those categories.

2. Technical Semantic Infrastructure: A Brief Overview

For readers unfamiliar with the technical landscape, the Semantic Web stack consists of:

2.1 Standards and Languages

RDF (Resource Description Framework): The basic data model — subject-predicate-object triples that express relationships between entities.
OWL (Web Ontology Language): A language for defining ontologies — formal specifications of concepts and their relationships.
SHACL (Shapes Constraint Language): A language for validating RDF data against defined shapes and constraints.
SPARQL: A query language for retrieving and manipulating data stored in RDF format.

2.2 Major Knowledge Graphs

Google Knowledge Graph: Powers Google Search's "knowledge panels" and question-answering. Reportedly contains billions of entities sourced from Freebase, Wikidata, Wikipedia, and proprietary data.
Wikidata: The largest open knowledge graph, containing 100+ million entities. Sister project to Wikipedia, maintained by volunteers. Used by Google, Amazon, Apple, Microsoft, and OpenAI.
DBpedia: Extracts structured data from Wikipedia infoboxes. One of the original Linked Data projects.
YAGO: Academic knowledge graph combining Wikipedia, WordNet, and GeoNames.

2.3 Enterprise Knowledge Graphs

Major corporations (IBM, Amazon, Samsung, eBay, Bloomberg, New York Times) maintain proprietary knowledge graphs for internal use — product catalogs, organizational knowledge, customer data structured as semantic entities.

3. The Political Economy Gap

Ford and Iliadis (2023), in "Wikidata as Semantic Infrastructure," identify the core problem:

"Third parties can legally store Wikidata's facts in their proprietary databases and thus lose their dependence on Wikidata and Wikipedia as a source over time, potentially negatively impacting data workers and the political economy of data labor."

This describes semantic liquidation in technical terms: volunteer labor produces semantic capital (Wikidata entries), which is then extracted by platforms (Google, OpenAI) and converted into proprietary assets that generate rent (subscription revenue, advertising) without compensating original producers.

The AoIR panel "Semantic Media: Political Economy Perspectives on Platformized Fact Production" (Iliadis et al., 2023) elaborates:

"The adoption (and domination) by platform companies of linked data has catalyzed a re-shaping of web content to accord with the question and answer linked data formats, weakening the power of open content licenses to support local knowledge and consolidating the power of algorithmic knowledge systems that favor knowledge monopolies."

This is semantic rent extraction through semantic infrastructure control: whoever controls how meaning is structured controls what can be known.

4. Mapping Technical to Economic Categories

The semantic economy framework provides accounting categories that map directly onto technical semantic infrastructure:

Technical Term	Semantic Economy Term	Description
Ontology engineering	Semantic labor	The work of defining concepts, relationships, and constraints
Knowledge graph	Semantic capital	Accumulated structured meaning that systems draw upon
RDF/OWL/SHACL standards	Semantic infrastructure	Background structures enabling meaning to be legible and actionable
API access / Knowledge panels	Semantic rent	Value extracted from stabilized meanings
Training data harvesting	Semantic liquidation	Conversion of accumulated meaning into monetizable assets
Model collapse / Data degradation	Semantic exhaustion	Depletion when extraction exceeds replenishment

4.1 Ontology Engineering as Semantic Labor

Building an ontology is semantic labor par excellence: defining classes, properties, relationships, and constraints that determine how a domain is understood. This labor is often:

Invisible: Ontologies function as infrastructure — noticed only when they fail
Non-fungible: Domain expertise cannot be easily substituted
Undercompensated: Much ontology work is academic or volunteer labor

The "metadata modelers" interviewed by Iliadis work at platform companies building proprietary ontologies. Their labor shapes how Google understands "restaurant" or how Amazon categorizes "electronics" — yet this labor rarely appears in accounts of platform value.

4.2 Knowledge Graphs as Semantic Capital

A knowledge graph is not merely "data" — it is accumulated semantic labor crystallized into structure. Wikidata's 100 million entities represent millions of hours of volunteer work: researching, verifying, formatting, linking.

This capital has specific properties:

Non-rival in use: Google and OpenAI can both use Wikidata without depleting it
Rival in capture: Only some entities can monetize access or control modification
Dependent on maintenance: Knowledge graphs require ongoing labor to remain accurate

4.3 Standards as Semantic Infrastructure

RDF, OWL, SHACL, and Schema.org are semantic infrastructure — they determine what kinds of meaning can be expressed and how meaning flows between systems. Control of standards is control of semantic infrastructure:

Schema.org (developed by Google, Microsoft, Yahoo, Yandex) shapes how websites structure data for search engines
W3C standards establish what counts as valid semantic markup
Proprietary APIs determine who can query knowledge graphs and how

4.4 Semantic Rent and Liquidation

When Google displays a "knowledge panel" sourced from Wikidata, it extracts semantic rent: value derived from stabilized meanings without performing the original labor. The Wikidata volunteers who created the entries receive no compensation; Google captures the value through advertising.

When OpenAI trains GPT on Wikipedia and Wikidata content, it performs semantic liquidation: converting accumulated semantic capital into a proprietary asset (model weights) that generates subscription revenue. In technical terms, this is irreversible representational capture — the semantic structure is distilled into parameters, severed from its sources, and enclosed. The original labor is not merely uncompensated — it becomes invisible, as users interact with ChatGPT without seeing its sources.

A note on framing: semantic liquidation is often structural rather than malicious. Platform architectures, licensing regimes, and market incentives create extraction dynamics that no individual actor necessarily intended. The point is not to assign blame but to make the dynamics visible and accountable.

4.5 Semantic Exhaustion

The technical literature documents early signs of semantic exhaustion:

Model collapse: AI systems trained on AI-generated content produce degraded outputs (Shumailov et al., 2023)
Knowledge graph incompleteness: Despite millions of edits, Wikidata remains "far from complete" (Guo et al., 2022)
Volunteer burnout: Wikidata editors experience "usage invisibility" — their labor powers systems that never acknowledge them (Zhang et al., 2023)

When extraction (training, API access, knowledge panels) exceeds replenishment (volunteer editing, ontology maintenance), semantic exhaustion occurs: the infrastructure degrades, outputs become less reliable, and the system loses coherence.

5. Implications for Semantic Web Research and Practice

5.0 A Clarification

This framework does not challenge the correctness of Semantic Web standards or machine learning architectures. RDF is a sound data model. OWL enables valid inference. Knowledge graphs are genuinely useful structures. The framework challenges something else entirely: the absence of accounting for labor and extraction in how these systems are built, maintained, and monetized. Technical excellence and political-economic critique are not in tension — the latter presupposes the former.

5.1 For Ontology Engineers

Your labor is semantic labor. The ontologies you build become semantic capital that others extract and monetize. Consider:

Licensing: How do your ontologies flow into commercial systems?
Attribution: Is your labor visible in downstream applications?
Sustainability: What replenishes the semantic capital you create?

5.2 For Knowledge Graph Practitioners

Knowledge graphs are not neutral technical artifacts — they embed decisions about what counts as knowledge, who is represented, and whose categories prevail. The "more-than-technical" nature of projects like Wikidata (Ford & Iliadis, 2023) means that technical decisions have political-economic consequences.

5.3 For AI/ML Researchers

Training data is semantic capital. When you train on Wikipedia, Wikidata, Common Crawl, or any text corpus, you are drawing on accumulated semantic labor. The semantic economy framework asks:

Whose labor produced this capital?
What compensation, if any, reaches them?
What happens when this capital is exhausted?

5.4 For Platform Studies

Platforms do not merely "use" semantic infrastructure — they capture and enclose it. Google's Knowledge Graph, built substantially from open sources (Freebase, Wikidata), is now proprietary. The semantic economy framework provides vocabulary for analyzing this enclosure.

6. The Semantic Economy Is Not a Metaphor

A potential objection: "Semantic economy" is merely a metaphor — a way of talking about meaning using economic language, without literal economic dynamics.

This objection fails for three reasons:

First, semantic labor produces measurable value. Platform market capitalizations depend substantially on semantic infrastructure — Google's ability to answer questions, Amazon's product categorization, Facebook's social graph. This is not figurative value.

Second, semantic extraction has real consequences for real workers. The Wikidata volunteers, the content moderators, the data labelers performing RLHF — their labor is extracted, and they experience the effects of non-compensation materially.

Third, semantic exhaustion is empirically observable. Model collapse is not a metaphor. Knowledge graph incompleteness is not a metaphor. Volunteer burnout is not a metaphor. These are measurable phenomena that follow the logic the framework predicts.

The semantic economy is the actual economy of meaning-production in digital capitalism. The framework does not impose economic categories on non-economic phenomena — it reveals the economic dynamics that were always present but lacked vocabulary.

7. Completing Berners-Lee's Vision

Tim Berners-Lee envisioned a Semantic Web where "computers and people work in cooperation." The technical infrastructure largely exists. What remains incomplete is the governance of that infrastructure — the accounting of who produces, who extracts, and who benefits.

Berners-Lee himself recognized this. His later work on Solid — a project for decentralized data ownership — reflects concern about platform capture of semantic infrastructure. But Solid addresses data ownership at the individual level; it does not provide a framework for analyzing systemic extraction.

The semantic economy framework completes Berners-Lee's vision by adding the missing ledger. The six core categories, in order:

Semantic labor — accounts for who builds the infrastructure
Semantic capital — accounts for accumulated meaning-resources
Semantic infrastructure — accounts for control over standards and access
Semantic liquidation — accounts for value extraction and irreversible capture
Semantic rent — accounts for ongoing value capture from stabilized meanings
Semantic exhaustion — accounts for systemic risk when extraction exceeds replenishment

With these categories, researchers and practitioners can analyze semantic systems not merely as technical architectures but as political-economic formations — with winners, losers, extraction, resistance, and sustainability conditions.

8. Conclusion

The Semantic Web exists. Knowledge graphs power search, AI, and digital infrastructure. The technical vision of machine-readable meaning has been substantially realized.

What has not been realized is the equitable Semantic Web — one where the producers of semantic labor share in the value their labor creates, where semantic capital is not enclosed by platforms, where semantic infrastructure serves diverse communities rather than consolidating monopolies.

The semantic economy framework does not prescribe solutions. It provides accounting categories that make the current situation legible. Once legible, it becomes contestable.

The semantic economy is not a metaphor. It has extraction, rent, and exhaustion.
