Abstract: Systems and processes for operating an intelligent automated assistant are provided. An example process includes receiving an utterance including a user request and determining whether at least a portion of the user request is ambiguous. If at least the portion of the user request is ambiguous then a set of context data based on the ambiguous portion of the user request is determined, metadata is extracted from the context data and a response to the user request is determined based on the extracted metadata.
