Semantic Router
Definition
A semantic router forwards queries to the appropriate processing path based on their meaning.
A non-uniformly standardized routing component that assigns requests to a route, data source, model class, or capability based on semantic features or intent.
Simply explained
Like an information desk, it recognizes your concern and sends it to the appropriate place.
Why it matters in practice
The term helps to design automated processes reliably, measurably, and with clear responsibilities.
Example from business
Contract questions go to the legal knowledge base, technical malfunctions to the ticket system.
Limits and pitfalls
- Using semantic similarity as authorization, equating router decision with query fan-out, forcing unknown requests into a route, or providing no fallback and quality measurement.
Origin & history
Semantic routing combines intent classification, embeddings, and orchestration.
Use in mid-sized companies
- Possible application: Contract questions go to the legal knowledge base, technical malfunctions to the ticket system.
