Content selection and presentation of electronic content

A system for populating an interest feed with electronic news article resources comprising:

• one or more processing devices;
• one or more non-transitory machine-readable storage devices for storing instructions that are executable by the one or more processing devices to cause performance of operations comprising:
• selecting, based on an interest list of a user, multiple electronic news article resources, each electronic news article resource including electronic media content comprising at least a portion of text content;
• detecting data similarities between a subset of the multiple electronic news article resources, wherein the data similarities comprise relative locations of certain portions of the text content of the subset of electronic news article resources;
• identifying, based on the data similarities, two or more related entities that are associated with the subset of electronic news article resources;
• selecting at least one pair of entities from the two or more related entities based on a quantity of electronic news article resources of the subset in which the at least one pair of entities are associated with one another;
• for the at least one pair of entities that are identified as topics of a particular electronic news article resource:
• determining, by the computing system and based on the quantity of electronic news article resources satisfying a threshold, that an event that is itself not included on the interest list of the user and that involves both entities of the pair is likely occurring;
• generating, by the computing system, a representation that corresponds to the event, the representation being generated based on one or more of the electronic news article resources in which each entity of the pair of entities is associated;
• and
• providing, by the computing system and for output to a user device, the representation that corresponds to the event on the interest feed.
