US Patent 10509829 Contextual search using natural language

A context aware digital assistant supported on devices such as smartphones, tablet computers, wearable computing devices, personal computers (PCs), game consoles, and the like is configured with a natural language interface that enables a user to launch searches for content using contextual references such as time, date, event, location, schedule, activity, contacts, or device. The user can thus use natural language to express the context that is applicable to the sought-after content rather than having to formulate a query that uses a specific syntax. The digital assistant can comprehensively search for the content across applications (i.e., both first and third party applications), devices, and services.
