| # GISTBench — Groundedness & Interest Specificity Test Bench
|
|
|
| GISTBench evaluates how well LLMs understand users from their engagement history. Given a user's interactions with content (videos, articles, books, etc.), the benchmark measures whether an LLM can extract meaningful interests, ground them in evidence, and cite specific relevant items.
|
|
|
| ## Dataset Details
|
|
|
| - **Rows:** 4,214,059 engagements
|
| - **Users:** ~1,000 anonymized users
|
| - **Format:** Parquet
|
|
|
| ### Schema
|
|
|
| | Column | Type | Description |
|
| |---|---|---|
|
| | `user_id` | `int64` | Anonymized user identifier |
|
| | `object_id` | `int64` | Anonymized content item identifier |
|
| | `object_text` | `string` | Text description of the content item |
|
| | `interaction_type` | `string` | One of: `explicit_positive`, `implicit_positive`, `implicit_negative`, `explicit_negative` |
|
| | `interaction_time` | `string` | Anonymized interaction timestamp |
|
|
|
| ### Interaction Types
|
|
|
| | Type | Meaning | Examples |
|
| |---|---|---|
|
| | `explicit_positive` | User actively expressed positive interest | Liked, favorited, rated highly |
|
| | `implicit_positive` | Passive positive signal | Watched fully, clicked through |
|
| | `implicit_negative` | Passive negative signal | Scrolled past, skipped |
|
| | `explicit_negative` | User actively expressed dislike | Downvoted, reported, rated low |
|
|
|
| ## Usage
|
|
|
| ```python
|
| from datasets import load_dataset
|
|
|
| ds = load_dataset("facebook/gistbench")
|
| print(ds)
|
| # DatasetDict({
|
| # train: Dataset({
|
| # features: ['interaction_type', 'user_id', 'object_id', 'interaction_time', 'object_text'],
|
| # num_rows: 4214059
|
| # })
|
| # })
|
|
|
| # Access rows
|
| print(ds["train"][0])
|
| ```
