# Optimizing Bots

<Badge icon="arrow-left" color="gray">[Back to NLP Topics](/ai-for-service/automation/natural-language/nlp-topics)</Badge>

Optimize your assistant's NLP by refining names, synonyms, patterns, and engine configurations. Start by defining synonyms at the task level, then manage them at the app level.

***

## NLP Optimization Options

Go to **Natural Language** for your assistant:

| Section                                    | What to configure                                                    |
| ------------------------------------------ | -------------------------------------------------------------------- |
| **Training > Machine Learning Utterances** | Add and manage utterances for intent recognition.                    |
| **Training > Synonyms & Concepts**         | Optimize intent/entity recognition with synonyms and concept groups. |
| **Training > Patterns & Rules**            | Define patterns for slang, idioms, and complex expressions.          |
| **NLU Config**                             | Set recognition confidence thresholds and engine-specific tuning.    |
