How can AI help detect duplicate records across bordereaux submissions?
Duplicate records in bordereaux submissions commonly arise from coverholder resubmissions, corrected versions of a prior submission, or overlapping reporting periods. Simple exact-match validation rules often miss duplicates where small differences exist between entries, such as a slightly different date format or a minor spelling variation. AI-assisted matching can identify likely duplicates by comparing records for overall similarity rather than requiring an exact match, flagging candidates for human review rather than removing them automatically, since confirming a genuine duplicate still requires operational judgement.
Key takeaways
- Duplicate records commonly arise from coverholder resubmissions, corrections and overlapping reporting periods.
- Exact-match validation rules often miss duplicates that differ slightly in formatting or spelling.
- AI-assisted matching can identify likely duplicates by comparing overall similarity rather than requiring an exact match.
- Flagged duplicates should be reviewed and confirmed by a person before being merged or removed.
Duplicate records rarely announce themselves. A risk that appears twice in a premium bordereau does not usually look wrong at first glance. It just looks like two entries, each individually plausible.
The consequence is not always obvious either, until premium totals are overstated, exposure figures are inflated, or a claim ends up reserved twice because it exists in the system under two slightly different references.
Catching duplicates reliably, particularly when they are not exact matches, is a persistent and often underestimated data quality challenge in bordereaux processing.
Why duplicate records occur in bordereaux submissions
Duplicates arise for mundane, recurring reasons rather than unusual errors.
A coverholder may resubmit a corrected bordereau after finding a mistake, without removing the original, incorrect entries from the system first. A risk with a mid-period change might appear on both the current and a prior period's submission if reporting cycles overlap slightly. A coverholder's own system might export the same underlying record twice under two different reference formats, particularly after a system migration or a change in how policies are numbered.
None of these causes indicate carelessness. They are a predictable consequence of data flowing from many different systems and processes into a shared reporting cycle.
How organisations traditionally tried to catch duplicates
Traditional duplicate detection typically relies on exact-match rules: flag two records as duplicates if their policy reference, premium amount and effective date are all identical.
This approach works reliably for genuinely identical entries, but it misses duplicates that differ even slightly, which is a common occurrence in practice. A resubmitted record might have a corrected premium figure, a policy reference typed with an extra space, or a date recorded in a different format. To an exact-match rule, these look like two different records, even though a person reviewing them side by side would likely recognise them as the same underlying risk.
How AI-assisted matching identifies likely duplicates
AI-assisted matching approaches the problem differently, comparing records for overall similarity across multiple fields rather than requiring every field to match exactly.
It can recognise that two entries with very similar insured names, closely matching premium amounts, and the same or adjacent dates are likely to represent the same underlying risk, even where no single field matches exactly. This allows it to catch near-duplicates that exact-match rules would miss entirely.
The output is typically a ranked list of likely duplicate pairs or groups, each with an indication of how confident the system is that the match is genuine, rather than a single definitive answer.
Why human review remains necessary
A flagged pair of records is a candidate for review, not a confirmed duplicate.
Two genuinely separate risks can, on occasion, share very similar characteristics without being duplicates at all, particularly for coverholders with a narrow product range where many risks look alike on paper. Treating every flagged pair as confirmed and removing one automatically risks losing genuine data.
For this reason, most organisations require a person to review flagged duplicate candidates, confirm which entry (if any) should be treated as the duplicate, and decide how the record should be corrected, before anything is merged or removed from the underlying data.
Example
A coverholder submits a corrected version of last month's premium bordereau after discovering an error, but the correction is added as a new submission rather than replacing the original, so both versions of several risks now exist in the insurer's systems.
The AI-assisted validation tool flags a set of records across the two submissions as likely duplicates, based on close similarity in policy reference, insured name and premium amount despite minor formatting differences. An analyst reviews the flagged pairs, confirms which version is correct, and removes the superseded entries before the data feeds into reporting.
FAQs
-
Can duplicate records be removed automatically once AI flags them?
Most organisations require human confirmation before removing or merging flagged records. An apparent duplicate might occasionally represent two genuinely separate transactions that happen to look similar, and an incorrect automatic removal could itself create a data quality problem.
-
How can duplicates be prevented rather than just detected?
Clear submission guidance to coverholders, such as requesting that corrections replace rather than supplement a prior submission, can reduce how often duplicates arise in the first place. This works best alongside ongoing detection as a safety net, rather than as a replacement for it.
-
Are duplicates only a risk in premium bordereaux?
No. Duplicate records can occur in claims and risk bordereaux as well. Duplicate claims entries in particular carry a risk of double-reserving or double-payment if they are not identified and resolved.
