Computerized assistance using artificial intelligence knowledge base

A computerized personal assistant, comprising:

• a natural language user interface configured to receive a user query;
• an identity machine configured to associate the user query with a particular user;
• a natural language processing machine configured to output a computer-readable representation of the user query;
• a knowledge-base query machine configured to query a user-centric artificial intelligence knowledge base associated with the particular user and to output a response to the user query based on a subset of user-centric facts in the user-centric artificial intelligence knowledge base satisfying one or more constraints defined by the computer-readable representation of the user query, wherein the user-centric artificial intelligence knowledge base is updateable to include a new or updated user-centric fact via an update protocol useable by a plurality of different computer services, the update protocol constraining a storage format of the new or updated user-centric fact to an application-agnostic data format.

A method for automatically responding to queries, comprising:

• recognizing a computer-readable representation of a query associated with a particular user of a computer service;
• querying a user-centric artificial intelligence knowledge base associated with the particular user via a query protocol useable by a plurality of different computer services;
• and
• outputting a response based on a subset of user-centric facts in the user-centric artificial intelligence knowledge base satisfying one or more constraints defined by the computer-readable representation of the query, wherein the user-centric artificial intelligence knowledge base is updateable to include a new or updated user-centric fact via an update protocol useable by a plurality of different computer services, the update protocol constraining a storage format of the new or updated user-centric fact to an application-agnostic data format.
