Korean Market Fear & Greed — LLM-Annotated Text Sentiment Dataset
LLM annotations of 1.28 million Korean financial texts (news headlines and retail investor community posts) and the resulting daily fear–greed index for the Korean stock market (research period 2021-01 – 2026-08, with a 2019–2020 news-only warm-up segment).
Companion dataset for: "Measuring fear and greed with large language models: Evidence from news and retail investor communities in the Korean stock market".
Files
| File | Rows | Description |
|---|---|---|
news_domestic_annotations.jsonl.gz |
~195k | Naver Finance main news, 2019–2026. Per-article: relevant, dims (7 sentiment dimensions, 0=extreme fear…100=extreme greed), reason, date/press/URL |
community_annotations.jsonl.gz |
~1.08M | DCinside stock gallery posts, 2021–2026. Per-post: relevant, stance (bull/bear/neutral), intensity (0–100), type (position/loss/gain/info/banter), timestamp, post id/URL |
news_foreign_annotations.jsonl.gz |
~8k | Foreign-outlet coverage of Korea (Google News), 2025–2026. Same schema as domestic news. Reference only (zero weight in the index) |
daily_index.csv |
~2.8k | Daily index: official percentile index pct_ema, absolute composite raw_score, per-source scores, community auxiliaries (com_vol_z, com_disagree, …), labels. See paper §2 |
daily_dims.csv |
— | Long-format per-source per-dimension daily detail |
audit/reannotation_audit_2021.jsonl.gz |
2,000 | Re-annotation audit sample (2021): post ids, original and re-annotated labels; relevance agreement 94.2%, stance 88.3% |
Original texts are not included (copyright). Every record carries its source URL / post id, so texts can be re-fetched. All paper results are reproducible from the annotations and the daily index alone (scripts included with the paper).
Annotation pipeline (fully unsupervised)
- Model: DeepSeek (vLLM, OpenAI-compatible), temperature 0, batched JSON outputs
- News: relevance + up to 7 dimension scores (only dimensions the article addresses)
- Community: relevance + stance/intensity/type, with explicit Korean slang/irony handling ("가즈아"=bullish, "한강"=bearish, irony resolved to actual sentiment)
- No human labels at any stage
Index construction (summary)
Daily composite = 0.6 × news (dimension-weighted mean over relevant articles)
- 0.4 × community bullishness. Official index = rolling 1-year percentile of the
composite, 5-day EMA. Community posting volume z-score (
com_vol_z) is computed against a trailing 60-day window. Capitulation signal =pct_ema < 25 AND com_vol_z > 2.
Caveats
- Community coverage: exhaustive from 2025-01, evenly-spaced 300 posts/day sample for 2021–2024
- 2019–2020 rows are a news-only warm-up for the percentile window — do not use them as the composite index
- KOSPI/VKOSPI market data are not redistributed (Naver/KRX); see paper scripts

Changelog
v1.1 (2026-08-12, Revision 1)
daily_index.csv/daily_dims.csvupdated: (i) community component dropped on days with <10 relevant posts (weight renormalized to news); (ii) community volume z-score re-initialized at the 2025-01-01 coverage-regime boundary (first 19 days of 2025 have no z); annotation files unchanged.- Added
prompts/: exact Korean system prompts used for annotation + English translations.
v1.0 (2026-08-12) — initial release.
v1.2 (2026-08-12, Revision 2)
- Added
audit/reannotation_audit_2021.jsonl.gz: the 2,000-post re-annotation audit sample (balanced 1,000 relevant / 1,000 irrelevant from 2021), with post ids, dates, URLs, original and re-annotated labels. Agreement: 94.2% (relevance), 88.3% (stance, on the 969 doubly-relevant posts).
