IPTC News Genre
IPTC News Genre separates expectations from official statements and reported outcomes throughout each scheduled market decision cycle.
Two articles can describe the same event but serve different purposes. A forecast states expectations. A curtain raiser prepares readers for a scheduled event. A press release carries an institution’s statement. Results report an outcome. Analysis interprets it. Genre preserves that role across subjects, sentiment and sources.[1]
The distinction matters around scheduled market events. Expectations form before a decision, official information arrives at a known time, and reporting then resolves uncertainty. Genre separates those stages before tests of tone, novelty or market response. World assigns one of 55 peer labels to every canonical event, making information state observable through event time. That sequence is directly testable.[2][3][4]

Foundations
News genre identifies editorial purpose without judging accuracy, quality or market impact
IPTC News Genre classifies editorial form. Its labels distinguish current events, forecasts, interviews, press releases, transcripts, results, analysis and other publishing conventions. The label does not describe the event’s subject or economic importance. It tells a researcher how the information was presented and what role the item was designed to perform.[1]
World assigns the dominant genre of the canonical event record. It does not verify factual accuracy, identify the original publisher’s intent or measure whether investors read the item. Genre can separate expectation-setting from outcome reporting, but a valid market test must still control for content, source, timing, novelty and policy surprise.[5][6]
Categories
IPTC News Genre uses 55 flat categories for editorial form
The ontology is flat. Every event receives one peer-level label, with no parent or child classes. The explorer exposes the formal definition, stable code and World V1.2 frequency for all 55 labels. Search keeps the interface consistent with larger hierarchical ontologies and preserves explicit category boundaries.

Example usage 1 of 3
Example Usage: FOMC genres separate market expectations from confirmed outcomes around scheduled policy decisions
Across 40 Federal Open Market Committee decisions from 2021 to 2025, Forecast and Curtain Raiser form 56.5% of pre-announcement coverage. Their share falls after each decision as Results and Press Release expand, without becoming a results-led regime. Matched weekdays confirm a smaller information clock around scheduled policy decisions.[2]
That clock prevents look-ahead leakage and cohort contamination. Pre-decision articles encode expectations; post-decision articles contain outcomes and official communication. Pooling them can make a model appear predictive when it has learned information released after the tradeable timestamp. Genre labels let researchers isolate anticipation, announcement and digestion before testing rates, currencies, equities or volatility.[2]
The coverage chart divides Federal Reserve events by all World events on the same dates. The forward-looking share combines Forecast and Curtain Raiser. The resolved share combines Results Listings and Statistics with Press Release. Each point pools 40 scheduled decisions. Matched dates use the same weekdays two weeks earlier. The comparison is descriptive and does not measure policy surprise or market impact.

Example Usage: Obituary labels remove recycled history from event studies around major deaths
Obituaries account for 59.9% of 554 Queen Elizabeth II events from her death through the funeral, compared with 3.7% of the same-date English baseline. The classification identifies the dominant block of retrospective reporting inside a global news surge rather than allowing it to masquerade as hundreds of independent information arrivals.[7]
This matters whenever a prominent death affects currencies, sovereign institutions, succession risk or exposed companies. Obituaries frequently repeat known history. Removing or down-weighting them prevents duplicated biography from inflating attention, sentiment and novelty measures. Researchers retain live announcements and institutional consequences while applying a cleaner event clock to genuinely new information.[1]
- Obituary
- +56.2pp
The fixed cohort contains 554 events from 8 to 22 September 2022, equal to 19,129 per million English World events. The same-date baseline contains 28,961 events during the matched two-week period surrounding the funeral and succession.

Example Usage: iPhone 16 coverage moves from previews into supplied and results-led formats
iPhone 16 launch coverage rises 69% after Apple's 9 September announcement, from 1,649 to 2,785 events per million. Curtain Raiser falls from 40.8% to 14.9% of assigned genres. Advertiser Supplied rises from 2.9% to 14.4%, while Results Listings and Statistics enters the reporting mix at 7.9% after launch.[8]
The transition exposes both an event clock and a source-format risk. Preview material arrives before the launch; supplied and results-led formats expand afterwards. Researchers can separate anticipation from product disclosure, but Advertiser Supplied content requires source controls before interpreting tone, novelty or market impact. Genre classification makes that contamination visible rather than silently pooling it inside one cohort.[1]

The fixed English cohort covers 15 August through 3 October 2024 and requires iPhone 16 or Apple Intelligence. Each line pools genre counts across the current and prior six days, then divides by all genre-assigned cohort events in that window. The marker is Apple's 9 September announcement.
