Corporate shocks propagate through distinct events. A software failure causes disruption. Remediation triggers customer actions. Losses bring claims and litigation. Management responses create governance, disclosure and earnings events. One topic label cannot preserve that sequence. [[ 1 ]](https://doi.org/10.1016/j.jbankfin.2005.09.015) The NOSIBLE Event Ontology maps reporting into 17 categories, 69 subcategories and 330 event types. World applies those paths to canonical event clusters with point-in-time dates and source coverage. Researchers can construct event chains, separate the initial shock from later consequences and test which stages affect exposed assets across the corporate resolution sequence through time. [[ 2 ]](https://www.finma.ch/en/news/2023/03/20230319-mm-cs-ubs/) [[ 3 ]](https://www.snb.ch/en/publications/communication/press-releases/2023/pre_20230319_1) Categories 416 categories Structure 3 levels World events labelled 29.8% Stable codes Since v1 Release data CC0 On this page [01 Foundations](https://nosible.com/ontologies/nosible-events#foundations) [02 Categories](https://nosible.com/ontologies/nosible-events#vocabulary) [03 Example usages](https://nosible.com/ontologies/nosible-events#trends) [04 Downloads and references](https://nosible.com/ontologies/nosible-events#downloads) Foundations ## The NOSIBLE Event Ontology separates corporate shocks from their downstream consequences The ontology is designed around investable corporate events. Categories separate operational, legal, regulatory, governance, earnings, capital-market, credit, reputation and competitive effects. Subcategories narrow the mechanism. Concrete event types specify the reported action or outcome. The hierarchy supports both broad samples and precise event studies across linked corporate event chains and market regimes. World classifies what a canonical event record reports. It does not prove causality, materiality or legal liability. A cascade can contain repeated reporting, parallel consequences and classification errors. Researchers should preserve event time, deduplicate source clusters, audit leaf labels and test whether downstream events add information beyond the initial shock, its immediate coverage and concurrent market conditions. [[ 1 ]](https://doi.org/10.1016/j.jbankfin.2005.09.015) Categories ## Seventeen categories expand into 330 concrete corporate events across three levels The NOSIBLE Event Ontology contains 416 categories: 17 roots, 69 subcategories and 330 leaf events at maximum depth two. The explorer loads bounded branches and exposes definitions, full paths and World counts. World V1.2 assigns a NOSIBLE path to 4,562,361 of 15,311,040 events, giving 29.8% corpus coverage.

Example usage 1 of 3 ### Example Usage: Credit Suisse coverage moves from liquidity crisis toward takeover, governance and resolution The cohort requires Credit Suisse plus crisis, loss, liquidity, deposit, UBS or rescue language. Normalized coverage rises from 91 to 802 events per million after the 19 March 2023 rescue announcement. The fixed entity and risk filter separates a resolution shock from the changing volume of the wider World corpus. [[ 2 ]](https://www.finma.ch/en/news/2023/03/20230319-mm-cs-ubs/) [[ 3 ]](https://www.snb.ch/en/publications/communication/press-releases/2023/pre_20230319_1) [[ 4 ]](https://www.news.admin.ch/en/nsb?id=93793) Capital Markets rises from 14.7% to 23.7% of ontology-assigned events. Corporate Governance rises from 13.2% to 20.0%, while Technical Analysis falls from 17.6% to 4.8%. FINMA and the Swiss National Bank records confirm the transition from confidence and liquidity stress toward takeover, governance and resolution. [[ 2 ]](https://www.finma.ch/en/news/2023/03/20230319-mm-cs-ubs/) [[ 5 ]](https://www.ubs.com/global/en/media/display-page-ndp/en-20230612-ubs-credit-suisse-acquisition.html) Normalized coverage **91 to 802** Capital Markets **14.7% to 23.7%** Corporate Governance **13.2% to 20.0%** **Coverage surges as Credit Suisse reporting moves into capital markets and governance** stacked rate per million World events · 14-day memory Capital Markets Corporate Governance Technical Analysis Credit Analysis Other The cohort requires Credit Suisse plus crisis, loss, liquidity, deposit, UBS or rescue language. The comparison splits at 19 March 2023. Coverage divides matched events by all World events in each phase. Composition divides by ontology-assigned cohort events. The result describes the resolution sequence; it does not measure loss severity, depositor behaviour, counterparty exposure or causal market impact. Example usage 2 of 3 ### Example Usage: Microsoft–Activision moves from antitrust review to layoffs within 100 days of closing Microsoft–Activision reporting changes event type three times. Antitrust Case Filed and Antitrust Case Updated dominate before the 13 October 2023 close. Merger Concluded peaks at completion. Workforce Reduced appears in late January 2024 and becomes the leading event type during the first restructuring wave roughly 100 days after the deal closes. [[ 8 ]](https://www.ftc.gov/legal-library/browse/cases-proceedings/2210077-microsoftactivision-blizzard-matter) Those phases carry different financial questions. Antitrust events change closing probability. Completion starts the ownership and accounting clock. Workforce reductions reveal integration costs and synergy execution. A single acquisition keyword merges all three. Event classifications let researchers align spreads, revisions, operating margins and competitor responses to the mechanism that actually changed during each distinct deal phase.

Each line pools event-type counts across the current and prior twenty days, then divides by all English World events in that window. Example usage 3 of 3 ### Example Usage: CrowdStrike reporting moves from outage disclosure into fraud cases and apologies CrowdStrike reporting changes event type after the 19 July 2024 outage. Cyber-attack and software-vulnerability classifications peak during the acute response. Fraud Case Filed appears in the following weeks, while Apology Statement Issued arrives later. The line chart exposes the sequence that pooled before-and-after shares conceal. [[ 6 ]](https://www.crowdstrike.com/en-us/blog/falcon-content-update-preliminary-post-incident-report/) Each phase starts a new risk clock. The outage affects clients, vendors and operations at once. Fraud cases and apologies shift attention to legal, insurance, churn and trust costs. Researchers can test prices, sales and client events by phase instead of pooling all CrowdStrike news into one risk signal.
