Techniques for building slot types and slot type artifacts are described. For example, in some implementations, a natural language understanding (NLU) service is implemented by instructions that upon execution are to cause: receiving a request to build a slot type, the request including an indication of one or more locations storing information need to build a slot type, a slot type being a list of one or more values used to train a machine learning model to recognize a value for a slot; retrieving a slot type definition bundle associated with the request, the slot type definition bundle at least including a slot type definition defining resolution activities for the slot type; building the slot type using the retrieved slot type definition bundle; and storing into the storage slot type artifacts produced from building the slot type to be used during an analysis of an utterance.
