Media Playback With Friend-Filtered, Time-Linked Comments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Social networking systems face challenges in presenting media content items that are most interesting or relevant to a user while avoiding emotionally distressing comments from unknown individuals, and in withholding complete comment threads to prevent emotional distress.
Innovation Solution
The system generates media content playback with comments only from friends, allowing private messaging with comment creators, and implements a cool-down period for notifications, while displaying comments at respective temporal positions during playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays all comments from all users on media content items, then the completeness of information is improved, but user emotional distress increases due to irrelevant or distressing comments from unknown individuals
Solution Approach 1:
The system segments comment visibility by user relationship type. Comments from friends are displayed by default, while comments from non-friends are hidden. This segmentation allows the system to maintain information completeness for relevant users while filtering out harmful content from unknown individuals, directly resolving the contradiction between comment completeness and user emotional distress
Solution Approach 2:
The system applies different visibility rules to different groups of commenters based on their relationship to the user. Friends' comments are made visible with high quality access, while non-friends' comments are restricted. This local quality approach ensures that each user receives appropriately filtered content based on their specific social context, reducing emotional distress while preserving relevant information
2Productivity
If the system presents media content items commented by friends to maintain user engagement, then user engagement is improved, but the system complexity increases due to friend relationship tracking and filtering
Solution Approach 1:
The system merges the friend relationship data already existing in the social networking system with the media content commenting functionality. By combining these existing structures, the system can filter and display friend comments without requiring a completely new architecture, thus improving user engagement while minimizing the increase in system complexity
Solution Approach 2:
The system leverages the existing friend relationship graphs and user profiles that are already maintained by the social networking system. These pre-existing structures automatically provide the filtering capability needed, allowing the media content feature to benefit from friend relationships without the system needing to independently track and manage all relationship data, thereby reducing overall complexity
3Loss of information
If the system displays complete comment threads to users, then the information completeness is improved, but user emotional distress increases due to lack of further comments from friends in response to user comments
Solution Approach 1:
The system segments comment thread visibility based on commenter identity. Within a comment thread, comments from friends are displayed while comments from non-friends are hidden. This segmentation ensures that users see complete threads of relevant conversations with their friends while filtering out potentially distressing content from unknown individuals, resolving the contradiction between thread completeness and emotional distress

AI summary
A method and a system include receiving a request from a client device to view a media content item, determining at least one comment associated with a respective user profile from a set of connected profiles, generating a summary comments selectable item based at least in part on the respective user profile, causing a display of playback of the media content item and the summary comments selectable item in response to the request to view the media content item, and during the playback of the media content item at the particular time, causing a display of at least one comment.
