Temporal features in a messaging platform

A non-transitory computer-readable storage medium comprising instructions executable by a processor, the instructions when executed causing the processor to:

• receive, from a computing device accessing a social media platform through a first account, a request for a message stream, wherein the social media platform is accessible by a plurality of accounts including the first account;
• retrieve, from a message repository of the social media platform, a set of two or more candidate messages;
• calculate a respective fatigue score for each candidate message, wherein calculating the fatigue score for a candidate message comprises:
• access a fatigue map that relates one or more accounts and messages viewed in one or more message streams by respective users of the one or more accounts, to retrieve information of one or more first messages associated with the candidate message, the one or more first messages having been previously presented to the first account, wherein entries of the fatigue map for the first account include timestamps identifying when respective first messages were viewed or interacted with by a user of the first account, and
• calculate the fatigue score for the candidate message as a function of the timestamps for the first messages and one or more fatigue factors assigned to each first message, wherein each fatigue factor for a respective first message is a weighting factor assigned based on a presentation format of the first message or a type of interaction by the user of the first account with the first message;
• remove, based on the respective fatigue scores, one or more candidate messages from the set of two or more candidate messages to derive a subset of one or more candidate messages, wherein each removed candidate message corresponds to one or more respective first messages having respective fatigue scores that exceed a specified threshold score;
• for each candidate message in the subset of one or more candidate messages, compute a likelihood value that represents a likelihood of engagement with the respective candidate message by a user of the first account;
• select, based on the likelihood values, one of the candidate messages in the subset of one or more candidate messages and inserting the selected candidate message into the message stream;
• and
• send the message stream to the computing device for display.
