Calendar-aware resource retrieval

A system comprising:

• a user interface that provides a user access to functionality of an electronic mail (email) application;
• a processor;
• and
• a memory device coupled to the processor, the memory device including a program stored thereon, wherein the program, when executed, causes the processor to perform operations comprising:
• determining that a calendar event is scheduled to occur;
• responsive to the determination, extracting or identifying features of a calendar event of the email application;
• generating, by a query of a database, a list of resources accessible by the user and related to the calendar event;
• ranking, by a machine learning (ML) model, the resources by a feature vector that indicates overlap between the extracted features of the calendar event and resource feature vectors representing content of respective resources of the list of resources;
• and
• causing respective summaries of a specified number of the respective resources with higher respective ranks to be output on the user interface.

At least one machine-readable storage medium including instructions for execution by processing circuitry to perform operations comprising:

• extracting content of a calendar event on an electronic mail (email) application, the content including a subject, one or more names of people attending or invited, a name of an organizer, a body, and a date and time of the calendar event;
• identifying, by a query of a database, a list of resources accessible by the user and related to the extracted content of the calendar event;
• ranking, by a machine learning (ML) model, the resources by a feature vector that indicates:
• (a) content similarity of respective resources and one or more of the subject and text in the body;
• (b) the names of people attending or invited and one or more names of people in the respective resources or metadata of the respective resources;
• (c) a temporal recency of the respective resources;
• and (d) a relationship of the respective resources to the calendar event in a resource-relation graph;
• and
• causing respective summaries of a specified number of the resources with higher respective ranks to be displayed on a display.

A method, performed by at least one processor of a computing system, the method comprising:

• extracting features of a calendar event on an electronic mail (email) application, the content of the calendar event including:
• a subject, one or more names of people attending or invited, a name of an organizer, a date and time, and text in a body, of the calendar event;
• generating, by a query of a database, a list of resources accessible by the user and related to the extracted content of the calendar event;
• ranking, by a machine learning (ML) technique, the resources by a feature vector that indicates overlap between the extracted features and at least two of:
• (a) content similarity of respective resources and one or more of the subject and the text in the body;
• (b) the names of people attending or invited and one or more names of people in the respective resources;
• (c) a temporal recency of the respective resources;
• and (d) a relationship of the respective resources to the calendar event in a resource-relation graph;
• and
• causing respective summaries of a specified number of the resources with higher respective ranks to be displayed on the user interface.
