Where this one gets misread
NLP is a field, not a capability. Being told a system uses NLP tells you nothing about whether it can do the specific thing you need, and it is usually said in place of a measurement.
Glossary

How Marella uses the term
We use “Natural language processing (NLP)” only where a product mechanism or an evaluation method backs it up, and we say when the behaviour depends on how a deployment is configured.
- Backed by a product mechanism or an evaluation method
- Deployment differences flagged
What this page does not prove
