# Inworld Graph Runtime Data Knowledge

[Overview](../overview) > [Inworld Graph Runtime Data](./InworldGraphRuntimeData) > Inworld Graph Runtime Data Knowledge

**Class:** `UInworldGraphRuntimeData_Knowledge` | **Inherits from:** `UInworldGraphRuntimeData`

Runtime data class for managing knowledge retrieval in Inworld graphs. This class manages knowledge sets used for information retrieval and question-answering operations within Inworld graphs. It supports dynamic adding, removing, enabling, and disabling of knowledge sets, with text embeddings used for semantic search and retrieval.
