    Study Notes

    TikTok Recommendation Feature

    • TikTok is developing an interactive feature that allows users to customize video recommendations based on their interests.
    • Users can provide their interests through surveys or freeform text input.

    Surveys

    • Surveys are triggered after user interactions with a video, with two types – positive and negative – based on the nature of interaction.
    • Four options in the survey:
      • Option 1: Fixed – See more/less content similar to the current video.
      • Options 2 & 3: Generated based on the video – View more of this content.
      • Option 4: Fixed – Allows users to express specific likes or dislikes.

    Freeform Text Input

    • Users enter their desired content preferences in freeform text.
    • The AI model processes the user's text, translating it into recommendations the recommendation system can understand.
    • The model’s interpretation is shown to the user for confirmation before refreshing the feed.

    Relevant Content Retrieval

    • After input, relevant content based on the prompt is retrieved.
    • Two types of prompts:
      • i2i (Item-to-Item): Users seek “more posts like this” or “fewer posts like this.”
        • Retrieved content is similar to the current video or the one associated with the freeform input.
      • Entity: Users specify a desired topic, like "cats," "Lady Gaga," etc.
        • Content matching the user's entity prompt is retrieved.

    Labeling Guidelines

    • Evaluation focuses on the relevancy of recommended content to the user prompt or the original post.

    Discard Rules

    • User prompts are discarded if they meet any of the following conditions:
      • Non-target language: Most words are not in the target language.
      • Unintelligible: User intent is unclear, even if most words are in the target language.
      • Personal data: User prompt contains any of these:
        • Full name (excluding single names/characters)
        • Individual phone number (excluding business numbers)
        • Individual email address (excluding business addresses)
        • Individual postal address (excluding business addresses)
        • ID numbers
        • Account numbers for personal/business accounts
        • Usernames (including public usernames)
        • Passwords/passcodes

    Prompt Type Classification

    • i2i (Item-to-Item) Prompt:

      • Users request "more posts like this" or "fewer posts like this," without specifying a specific topic.
      • Examples: “More”, "Love", "Relatable", "Plus", "More posts like this lifeguard"

    • Entity Prompt:

      • Users ask for specific content types, languages, formats, creators, etc.
      • Examples: "More basketball videos", "less news", "More yoga videos in Spanish"

    • Entity Prompt Aspects:

      • What: Specific theme/topic (e.g., Cats, Basketball videos)
      • Action: Boost (more), Deboost (fewer), or remove entirely (no)
      • Format: Video, photo, live streaming, ads, or unknown (if not specified)
      • Content Language: English (en), Spanish (es), etc., or unknown (if not specified)
      • Creator: Friends, follow, or unknown (if not specified)

    Content Labeling Procedure

    • Step 1: Label Prompt Type: Identify prompt as either "i2i" or "entity."
    • Step 2 (for i2i only): Label Original Video Clarity: Determine if the original video is clear and conveys a clear meaning.
      • "Yes" if clear, "No" otherwise.
    • Step 3: Label Recalled Content Relevancy: Evaluate the relevancy of each recommended post to the original post or user prompt.
      • "Relevant" if both text and visual information match, "Not relevant" otherwise.
      • "Uncertain" if the video is blurry, unclear, or conflicting.
      • "Not available" if the video link is broken.
    • Step 4: Calculate Overall Accuracy: Calculate the proportion of relevant content to total recommended content: "Overall Accuracy = No. of relevant / (No. of relevant + No. of irrelevant)"

    Additional Notes

    • The labeling process involves evaluating 6 recommended posts in most cases, although fewer posts may be available.
    • The platform automatically categorizes overall accuracy into ranges, like 0%, 1-25%, 6-49%, 50%, 51-75%, 76-99%, or 100%.
