Small Entity Errors Can Undermine the Entire Story
A name wrong by one letter. A date off by one year. A location in the wrong city. Entity errors in AI summaries are common and compound. How to verify names, dates, and locations before publishing.
Who this is for
Journalists, reporters, editors, fact-checkers — Working journalists and editors who receive AI-generated summaries, research, or drafts and need to verify that names, dates, and locations are correct before publication
The problem
Entity errors are often caught last and published first. A name misspelled by one letter, a date off by one year, a location given as the capital city when the event happened somewhere else — these feel minor during drafting and consequential after publication. AI models pattern-match on frequently appearing information, not on whether a specific name, date, or location is correct for the specific context in question.
Entity errors also compound. A wrong date makes the timeline wrong. A wrong location changes the jurisdiction. A misidentified person becomes a false attribution. Getting these right is not a detail task — it is the structural accuracy that everything else in the story rests on.
How ConvergePanel helps
Entity verification is a distinct step from claim verification. It requires checking specific names against primary sources, dates against records, and locations against contemporaneous reporting — independently of whether the broader claim is accurate. ConvergePanel's multi-model comparison helps surface entity divergence: when models give different names, different dates, or different locations for the same element of a story, that divergence is a flag.
How they compare
| Entity type | What to verify | Primary source to use | Common AI error |
|---|---|---|---|
| Person's name | Full legal or public name, spelling, middle name or initial | Official biography, organization website, public record | Common-name collision — correct first and last name but wrong individual |
| Title or role | Current title at the time of the event, not current title | Contemporaneous organizational record or news report | Using current title for a role the person held years earlier |
| Event date | Exact date the event occurred vs. date it was reported | Contemporaneous news report, official record, or court filing | Publication date substituted for event date; year off by one |
| Location | Specific venue, city, and country — not just country or region | Contemporaneous news report, official record, or photograph record | Capital city substituted for actual location; venue name from different event |
How it works
- 1List every person named in the AI summary: extract full names, titles, roles, and organizations
- 2List every date: event dates, publication dates, legal dates, and time references
- 3List every location: cities, venues, regions, countries, and jurisdictions
- 4For each name: verify against a primary source — official biography, organization website, public record, or contemporaneous report
- 5For each date: find a contemporaneous primary source (news report, official record, court filing) that confirms the date for that specific event
- 6For each location: confirm against a contemporaneous primary source or geographic record
- 7Submit the summary to ConvergePanel and note where models give different names, dates, or locations for the same element
- 8Resolve any divergence by going to the primary source for that specific entity
Use cases
- Checking an AI summary of a news story before incorporating specific names or dates into a report
- Verifying entity data in an AI-generated profile of a public figure before publication
- Fact-checking dates and locations in an AI-generated timeline before using it in an investigation
- Reviewing AI-assisted research notes for name, date, and location accuracy before they enter a draft
Why AI Gets Entities Wrong
AI models generate names, dates, and locations from pattern-matching on training data. For frequently mentioned entities, the model has seen the same combination many times and reproduces it reliably. For less-covered entities, the model may produce a plausible name that belongs to a different person, a date that appears nearby in the training data, or a location associated with the topic rather than the specific event.
The most common source of entity errors is similarity: two people with the same or similar names in the same field; two events with the same participants in the same location but different years; two locations associated with the same organization that are easily confused.
Entity Verification Checklist
- Full name — verify spelling, full legal or public name, and whether the name is the person's commonly used name or a variation
- Middle name or initial — check for disambiguation against others with the same first and last name
- Title or role — verify the title the person held at the time of the specific event, not their current title
- Organization — verify the exact organization name and whether the person actually belonged to it at that time
- Same-name collision — search for other individuals with the same or similar name who could be confused
- Event date — verify against a contemporaneous record, not a later article about the event
- Publication date vs. event date — distinguish when something was announced from when it occurred
- Location specificity — verify city and venue, not just country or region
- Time zone — for international stories, confirm whether the stated time is local or GMT
- Current vs. historical name — verify that the place name used is correct for the period in question
- Jurisdiction — for legal stories, confirm the specific court, territory, or regulatory body
- Organization name at the time — institutions change names; verify the name that was in use at the event date
Same-Name Collisions
Same-name collisions are one of the most frequent sources of AI entity error and one of the most damaging for published stories. Two people with the same name in the same field — politicians, researchers, executives, public officials — can be conflated without any other indicator that something is wrong. The name is correct; the person is not.
When a named individual appears in an AI summary, always verify not just that the name is correctly spelled but that it refers to the specific individual relevant to the event in question. Common disambiguation checks: employer and role, geographic location, age range where publicly available, and confirmation in a primary source that refers to this individual specifically in connection with this event.
Frequently asked questions
Why are AI entity errors so common if the facts appear correct?
AI models generate names, dates, and locations from training data patterns. They produce the entity most commonly associated with a topic, role, or context — which may be the right entity type but the wrong specific instance. The model has no mechanism to verify that a specific individual, date, or location is correct for a specific event; it reproduces the most likely candidate based on patterns.
What is a same-name collision in AI research?
A same-name collision is when an AI references the correct name but the wrong individual bearing that name. Two researchers with the same name, two politicians with the same surname, two executives with the same first and last name — the AI attributes a statement, role, or action to the right name but the wrong person. The check is verifying, via a primary source, that the named individual was actually connected to the specific event.
How do I verify a date that an AI gives for a historical event?
Find a contemporaneous primary source — a news report, official record, court filing, or organizational announcement published at the time of the event. Do not rely on later articles about the event, which may have introduced errors. Where multiple contemporaneous sources give different dates, note the discrepancy and use the source with the most direct connection to the event.
Is the location the AI gives for an event usually wrong?
Not always, but AI location errors are common for: events that moved between locations, events associated with an organization's headquarters rather than where they occurred, international events where the AI defaults to the capital city, and events named after a location that is not where they took place. Always verify against a contemporaneous source.
Does ConvergePanel help with entity verification?
ConvergePanel helps surface entity divergence: when multiple models give different names, dates, or locations for the same element of a story, that divergence flags the entity for primary-source verification. The primary-source check still requires human review of the specific records — ConvergePanel surfaces which entities need the most scrutiny.
