Methods, systems, and media for creating and updating a group of media content items

A system for identifying and updating a group of media content items, the system comprising:

• a hardware processor that is programmed to:
• receive, from a user device, one or more indications of filtering criteria to be applied to a corpus of media content items;
• store the received indications of filtering criteria in connection with an identifier of a collection of media content items;
• receive, from the user device, a first request to present the collection of media content items;
• in response to receiving the request, identify a first collection of media content items, wherein the first collection of media content items includes a plurality of media content items associated with a particular topic;
• identify a first group of candidate media content items, wherein the first group of candidate media content items includes media content items not included in the first collection of media content items;
• create a second collection of media content items by applying the stored filtering criteria to the first collection of media content items and the first group of candidate media content items;
• cause a user interface that indicates the second collection of media content items and the identifier of the collection of media content items to be presented on the user device;
• receive, from the user device, a second request to update the second collection of media content items;
• in response to receiving the second request, identify a second group of candidate media content items from the one or more sources of media content;
• modify the second collection of media content items by applying the stored filtering criteria to the second group of candidate media content items;
• update the user interface by indicating the modified second collection of media content items;
• and
• cause the updated user interface to be presented on the user device.

A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for identifying and updating a group of media content items, the method comprising:

• receiving, from a user device, one or more indications of filtering criteria to be applied to a corpus of media content items;
• storing the received indications of filtering criteria in connection with an identifier of a collection of media content items;
• receiving, from the user device, a first request to present the collection of media content items;
• in response to receiving the request, identifying a first collection of media content items, wherein the first collection of media content items includes a plurality of media content items associated with a particular topic;
• identifying a first group of candidate media content items, wherein the first group of candidate media content items includes media content items not included in the first collection of media content items;
• creating a second collection of media content items by applying the stored filtering criteria to the first collection of media content items and the first group of candidate media content items;
• causing a user interface that indicates the second collection of media content items and the identifier of the collection of media content items to be presented on the user device;
• receiving, from the user device, a second request to update the second collection of media content items;
• in response to receiving the second request, identifying a second group of candidate media content items from the one or more sources of media content;
• modifying the second collection of media content items by applying the stored filtering criteria to the second group of candidate media content items;
• updating the user interface by indicating the modified second collection of media content items;
• and
• causing the updated user interface to be presented on the user device.
