Supported languages for machine learning models

This is for:

Language support and relevance disclaimer

The Coveo Platform supports a wide range of languages across indexing, machine learning models, and user interfaces; however, the depth of linguistic processing varies by language. Support for a language doesn’t constitute a commitment to equivalent relevance, accuracy, or feature parity.

For example, queries and indexed content in languages such as English, French, German, and Spanish achieve higher and more consistent relevance due to more comprehensive language analysis and optimized platform components. Conversely, for other languages that are technically supported but for which the platform isn’t fully optimized, search relevance, generated answers, and overall accuracy can be reduced or be less consistent. Accordingly, language support doesn’t guarantee equal relevance quality, and observed outcomes can vary depending on the language.

The following table outlines the languages supported by the Coveo Machine Learning (Coveo ML) models.

Note

ART, QS, PQS, DNE, CR, and IAPR models can support content in languages other than those listed in the following table as long as the language uses spaces to separate words. For languages that meet this requirement, most language features are supported.

Available ML models:

Automatic Relevance Tuning (ART)
Case Classification (CC)
Content Recommendations (CR)

Note

Content Recommendations (CR) models are language agnostic, meaning that they can provide recommendations regardless of the language used in their metadata.
Passage Retrieval (CPR)
Dynamic Navigation Experience (DNE)
Intent-Aware Product Ranking (IAPR)
Predictive Query Suggestions (PQS)
Product Recommendations (PR)

Note

Product Recommendations (PR) models are language agnostic, meaning that they can recommend products regardless of the language used in their metadata.
Query Suggestions (QS)
Relevance Generative Answering (RGA)
Semantic Encoder (SE)
Smart Snippets
