Disambiguating contacts using relationship data

Abstract

Technologies are disclosed for disambiguating contact information using relationship data using a virtual assistant. A user interacts with a virtual assistant to obtain and utilize contact information. For example, a virtual assistant may allow users to perform an action that utilizes contact information (e.g., make a call to a contact). The virtual assistant utilizes a contact service to identify candidate contacts that are related to the requesting user. The contact service identifies candidate contacts based on relationship data between the requesting user and the stored contacts. For example, the relationship data may indicate that the requesting user is on the same project or team as another contact, that the requesting user has the same role as another contact, that the requesting user is a manager of another contact, as well as other attributes. In some examples, the contact service limits the number of candidate contacts provided to requesting user.
