Oxford sells lookup data for embedding in products. Linguabase is a semantic reasoning engine.
Oxford answers: “What does X mean?” and “What’s similar to X?”
Linguabase answers: “How does X connect to Y?” and “What’s between them?” and “Which sense of X connects to which sense of Y?”
Traditional dictionaries and thesauruses are designed for word substitution — helping writers replace one word with another. Linguabase is designed for concept exploration — understanding how ideas connect across meaning-space.

Relationship Comparison
Oxford’s thesaurus is excellent at what it does — finding substitute words. But that’s a different problem than finding associated concepts.
Oxford helps writers find substitute words. Linguabase helps applications find where users’ minds might go — including senses (pool shots, aviation banking, blood banks) that thesauruses don’t cover at all.
Definition Comparison
The clearest difference is in how definitions are structured.

Linguabase “spring”
The noun spring may describe the season following winter when days lengthen and plants start growing; a natural supply of water from the ground (mineral spring); or a device that returns to its original shape when force is removed. Spring also describes a lively quality, suggestive of the rebounding force of spring. To spring is to move suddenly and quickly, often upwards. An instance of this is also called a spring. Something that springs a leak suddenly starts leaking.

We’re Not Competing on Brand
Oxford has 150 years of brand equity. We have over a decade of graph engineering.
We’re not offering a cheaper Oxford. We’re offering something Oxford literally cannot provide: graph traversal through meaning-space with quality-rated, sense-aware, directional relationships.
If you need to embed dictionary lookups in an e-reader, use Oxford. If you need to navigate semantic space for games, AI, or exploration — that’s what we built.
