Explorer_LLM_Rec_Competition
This dataset contains user historical behaviors and content metadata, constructed from real user interaction histories. It covers behavior sequences across multiple domains for a single user and supports cross-domain recommendation, semantic-ID retrieval / generation, content understanding, and related tasks.

Anonymization & Join Rules
- All
pid / item id / author id / live id are hashed int64 values.
- The user table contains no
uid; each row is an anonymous user sample.
- Hashed item ids join the three item-metadata tables via
(domain, pid).
- Regular videos and ads both come from the video system, distinguished by
domain:
- Regular video:
video/video
- Ad:
video/ad
- Some users' video-watch sequences also contain ads.

OneReason_UserProfile
Each row is an anonymous user-profile sample containing behavior sequences from e-commerce, short-video, live-streaming, and ad domains.
Sequence Alignment Rules
user_history fields are grouped into 4 domains. Each domain has one or more primary sequences (pid / ID sequences), and every primary sequence is paired with a set of aligned feature sequences of identical length. If both a primary sequence and its aligned feature sequences are null, the user has no behavior in that domain.
