menu_bookWorking Definition

To maintain objective reporting, this tracker utilizes the Working Definition of Antisemitism as adopted by the International Holocaust Remembrance Alliance (IHRA):

“Antisemitism is a certain perception of Jews, which may be expressed as hatred toward Jews. Rhetorical and physical manifestations of antisemitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities.”

We apply this standard to distinguish between legitimate political expression and antisemitic manifestations in all documented reports.

02 · Editorial Standards

gavelWhat Counts as an Incident

Every article that reaches this platform passes through a multi-stage verification pipeline. These are the standards that govern which events are documented — and which are not.

An incident must satisfy all three conditions

1. 01
   A specific harmful act occurred:Assault, vandalism, a credible threat, discriminatory expulsion, property destruction, desecration of religious artifacts, or targeted hate mail. A harmful act must be identifiable — not merely alleged, implied, or reported as a general trend.
2. 02
   The act was motivated by antisemitism:The act must be directed at Jewish people because of their Jewishness — not because of citizenship, politics, or affiliation with a state or organization. Hostility toward Israel as a nation does not automatically constitute antisemitism.
3. 03
   The article is reporting the incident — not discussing it:Opinion pieces, editorials, commentaries, and academic analyses of antisemitism are not incidents. A news report about the history of antisemitism is not an incident. Only articles describing a specific, real-world event qualify.

Automatic exclusions

Human review: Automated classification is a first-pass filter, not a final verdict. Incidents queued for review are evaluated by the platform editor before any change in status. Data corrections can be requested at any time via the contact address below.

03 · Pipeline

analyticsData Methodology

Accuracy is our highest priority. Every incident passes through a multi-stage pipeline:

1. 01
   Automated Intelligence Pipeline:Our background engine continuously queries multiple news APIs every 15 minutes using an expanded dictionary of antisemitism-related search terms — covering explicit acts, institutional targets, dogwhistles, and reporting language.
2. 02
   Source Vetting:Priority is given to verified news organizations (e.g., JTA, ADL, Times of Israel, local newspapers) and official law enforcement statements. Articles from unverified sources are flagged for manual review.
3. 03
   Heuristic Verification:Incidents are marked as Verified only if they meet high-confidence criteria (arrests made, school board confirmation, or multiple independent reports). Others remain Pending Review until corroborated.
4. 04
   Evidence Preservation:Source web pages are automatically downloaded and SHA-256 hashed through our Evidence Vault, creating immutable forensic snapshots. This ensures that even if articles are removed, the evidentiary record is preserved.
5. 05
   Legal Cross-Reference:Tracked subjects are automatically linked to federal court dockets via the CourtListener/PACER system, connecting documented incidents to real legal proceedings and ensuring accountability extends to prosecution.
