SENTiVENT v1.1 Economic Events and Implicit Sentiment

SENTiVENT is a high-quality human-annotated financial news dataset for economic event extraction, implicit economic sentiment analysis, aspect-based sentiment analysis, and joint event-sentiment evaluation. Here, implicit sentiment means investor-relevant polarity inferred from factual news through common sense and world knowledge, not only explicit opinion wording. The corpus contains 170,398 tokens across 288 fully annotated English business-news articles about 30 S&P 500 companies. It includes 6,245 event mentions, 13,780 event arguments, 3,669 sentiment expressions, and 4,429 sentiment-target tuples. Articles were collected from diverse online financial-news sources and selected for sector diversity, temporal spread, topical diversity, and suitability for linguistic annotation. The resource is designed to be representative of the business-news genre: article selection avoids over-representing one company, sector, topic, or news event, and excludes robo-written or templated articles.

What SENTiVENT Provides

SENTiVENT is intended for reproducible evaluation of information extraction and implicit economic sentiment analysis in financial news.

• Human-annotated economic event, argument, sentiment-expression, sentiment-target, and event-sentiment labels.
• A joint document-level target that links event triggers, participants, fillers, sentiment expressions, entity/aspect/event targets, and polarity.
• Consistent train/dev/test splits across configs matching the pre-existing SENTiVENT papers for benchmark comparison.
• Research-standard document, sentence, and token-span interoperability views for baselines, prompting, and evaluation.

Implicit sentiment captures cases where factual business-news content changes a reader-investor's attitude toward a company, asset, person, product, or event because readers know what is desirable or undesirable in financial markets, even without words like great or bad. Implicit sentiment in financial news is challenging because articles are written objectively and the evidence is lexically diverse and requires common-sense world knowledge to resolve.

Uses

SENTiVENT is intended for research and evaluation in information extraction, implicit economic sentiment analysis, and structured-output modeling over financial news. The corpus covers English company-specific business-news articles about 30 S&P 500 companies from June 2016-May 2017, so results may not transfer directly to other languages, later market periods, informal text, non-US companies, or broader financial-advice settings.

How To Use

from datasets import load_dataset

unified = load_dataset("GillesJacobs/sentivent")
unified_continuous = load_dataset("GillesJacobs/sentivent", "sentivent_unified_document_continuous")
sentences = load_dataset("GillesJacobs/sentivent", "sentivent_unified_sentence")
uie_sentences = load_dataset("GillesJacobs/sentivent", "sentivent_unified_uie_sentence")
textee_events = load_dataset("GillesJacobs/sentivent", "ere_textee_sentence_e2e")
iabsa_quads = load_dataset("GillesJacobs/sentivent", "iabsa_quad_sentence")

The anonymized raw WebAnno/UIMA XMI source export is included under raw_webanno_export/ for users who need the original annotation files. It is a source artifact, not a recommended modeling or evaluation config.

Main Task

• The primary public config is sentivent_unified_document, the compact view for joint economic event extraction, implicit economic sentiment, and event-targeted sentiment in one structured target.
• sentivent_unified_document uses the full article text as input and emits event triggers, participants, fillers, sentiment expressions, non-event targets, and event-sentiment links with token, character, and text spans.
• sentivent_unified_sentence mirrors the same schema one source sentence at a time for smaller models, prompt-size constrained evaluation, and sentence-window pipelines; cross-sentence arguments, targets, and relation endpoints are omitted.
• Use sentivent_unified_document_continuous only for tools that cannot consume discontinuous spans; it fills span gaps and is therefore a derived lossy evaluation view.

Joint Document Row Shape

The default config is an article-level JSON object. text is the model input; annotations and relations are the structured target. This compact example shows the main nested shapes; long token and annotation lists are shortened.

Corpus And Annotations

SENTiVENT contains company-specific English financial news about 30 S&P 500 companies from June 2016-May 2017. Articles were selected from diverse online business-news sources for sector balance, temporal spread, topical diversity, source quality, and suitability for detailed linguistic annotation; duplicate, low-relevance, templated, and non-company-specific items were removed.

The annotations cover ACE/ERE-style economic events and implicit economic sentiment in one joint layer: event triggers, event types/subtypes, participants, fillers, event coreference, event attributes, sentiment expressions, entity/aspect/event targets, polarity, and event-implied sentiment.

The holdout test set is a gold-standard expert-adjudicated reference set from a three-annotator agreement study. Reported agreement is almost-perfect for event main type (Fleiss kappa=0.877, Krippendorff alpha=0.874), substantial for event full type/subtype (kappa=0.813, alpha=0.809), and substantial for directly annotated sentiment polarity (kappa=0.778, alpha=0.782).

Recommended Configs

Config	Best for	Task and references
sentivent_unified_document	Canonical joint benchmark for ML and LLM evaluation	Full-article structured IE: extract economic event triggers, types/subtypes, participants, fillers, implicit sentiment expressions/targets, and event-sentiment links. See the event extraction paper, implicit sentiment paper, and SENTiVENT thesis.
sentivent_unified_document_continuous	Systems that cannot represent discontinuous spans	Same joint document task for span-limited extractive tools; discontinuous spans are filled to one covering extent, so this is a lossy convenience view. See the event extraction paper and implicit sentiment paper.
sentivent_unified_sentence	Smaller-context joint sentence evaluation	One row per source sentence with the same event/sentiment schema as the document target. Cross-sentence arguments, targets, and relation endpoints are cut so each row is self-contained. See the event extraction paper, implicit sentiment paper, and SENTiVENT thesis.
sentivent_unified_sentence_continuous	Sentence-window tools that cannot represent discontinuous spans	Same sentence-level joint task, after row-local filtering, with retained discontinuous spans filled to one covering extent. This is a lossy convenience view for span-limited tools. See the event extraction paper and implicit sentiment paper.

Dataset Configs
