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.
## Files
| File | Description |
|------|-------------|
| `OneReason_UserProfile/` | Per-user multi-domain behavior records (~500k rows) |
| `OneReason_Pid2Sid/` | Mapping from content PID to three-segment semantic ID |
| `OneReason_Pid2Caption/` | Mapping from content PID to text caption |
| `OneReason_Pid2Tag/` | Mapping from content PID to level-3 category tag |
| `OneReason_General/` | General knowledge data |

## 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.
## Domain Values
| Domain | Meaning | Associated user fields | Token prefix |
|--------|---------|------------------------|--------------|
| `video/video` | Regular short videos | `video_*`, `video_history_*` | `<\|video_begin\|>` |
| `video/ad` | Ads / outer-loop content | `outer_loop_*` | `<\|ad_begin\|>` |
| `goods` | E-commerce products | `ec_*` | `<\|prod_begin\|>` |
| `live` | Live-streaming hosts | `live_hist_author_id_list` | `<\|living_begin\|>` |

## OneReason_Pid2Sid
Semantic-ID mapping table. Converts a content ID into a three-segment semantic ID.
| Field | Type | Description |
|-------|------|-------------|
| `pid` | int64 | Hashed content / product / host ID |
| `domain` | string | Domain of the content (see Domain Values) |
| `sid_three` | list[float] | Three-segment semantic ID `[s_a, s_b, s_c]` |
Token concatenation example:
```text
video/video: <|video_begin|><s_a_123><s_b_456><s_c_789>
video/ad: <|ad_begin|><s_a_123><s_b_456><s_c_789>
goods: <|prod_begin|><s_a_123><s_b_456><s_c_789>
live: <|living_begin|><s_a_123><s_b_456><s_c_789>
```
## OneReason_Pid2Caption
Lookup of a content's text description by hashed PID.
| Field | Type | Description |
|-------|------|-------------|
| `pid` | int64 | Hashed content / product / host ID |
| `domain` | string | Domain of the content (see Domain Values) |
| `caption` | string | Content description, or stringified list of description tags |
## OneReason_Pid2Tag
Level-3 category tag for video, ad, and live content.
| Field | Type | Description |
|-------|------|-------------|
| `pid` | int64 | Hashed content / host ID |
| `domain` | string | Domain; currently `video/video`, `video/ad`, `live` |
| `tag_lv3` | string | Level-3 category tag |

## 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.
#### `video/video` (short video)

| `video_history_sampled_pid_list` | `video_history_neg_feedback_list`, `video_history_like_list`, `video_history_comment_list`, `video_history_forward_list`, `video_history_collect_list`, `video_history_watch_time_list`, `video_history_play_done_list`, `video_history_duration_list`, `video_history_ts_list` |
