# TrendFact
TrendFact is the Chinese fact-checking benchmark from our ACL 2026 paper *TrendFact: A Benchmark Towards Hotspot Perception in Automatic Fact-Checking*.
Unlike earlier datasets built mostly on Wikipedia, most claims in TrendFact are drawn from trending platforms, so every sample comes with real dissemination signals. We use it to study a mostly overlooked question: when claims differ in social impact, should — and can — a fact-checking system adapt how much reasoning effort it spends on them? We call this the Hotspot Perception Ability (HPA).
## Data
- **7,643** samples across five domains: public health, science, society, politics, and culture
- an evidence library of **366,634** entries
- supports three tasks: evidence retrieval, fact verification, and explanation generation
### `TrendFact.json`
The main data. Each sample has the following fields:
| Field | Description |
|-------|-------------|
| `claim` | the claim to be verified |
| `label` | 0 = SUPPORT, 1 = REFUTE, 2 = NEI (not enough info) |
| `evidence` | gold evidence, with `text` / `url` / `target_idx` |
| `explanation` | human-annotated explanation |
| `domain` | domain the claim belongs to |
| `views` / `Discussion` / `Engagemen` / `Post` | four hotspot indicators |
| `influence_score` / `final_influence_score` | influence scores |
| `ori_title` / `url` / `date` | original title, source link, and date of the claim |
### `evidence.parquet`
The evidence library, 366,634 entries in total, with fields `url` / `text` / `publish_date`. Used for the evidence retrieval task.
