Know the Health of the Record a Nation Keeps

An AI Health Check and Continuous Monitoring of the Archive's Holdings and Catalogue

The AITS Content Tracking System (CTS) gives an executive one number: a composite Repository Health score. At 98.4%, you know your holdings are soundly described and findable, and you can say so with confidence in any room. At 64%, there is work to do, and the breakdown behind the score shows exactly what it is.


BI charts and reports show you the data. CTS uses AI and machine learning to tell you what it means: how healthy the repository is, what is driving the score, and what to do to improve it.


You choose what healthy means. The score is built from the KPIs that you and your managers select and weight. AITS recommends a proven starting set, and you add to it, drop from it or change the weights as your priorities change.


Behind the score is AI trained on your own holdings. It begins with a health check that establishes where the repository stands today, then keeps the score current around the clock, for every record and description as it is added.


For example: a file unit whose title is only a number, a digitized record with no searchable text, or an item whose dates fall outside the dates of its own series. CTS flags it, scores its effect on repository health, and recommends action, before a researcher or an AI assistant fails to find the record.


What you receive: the score, the breakdown behind it, and a prioritized list of what to fix first. It is evidence you can show a minister, a board or an auditor.


You do not have to imagine it. The live demo shows CTS measuring a real public collection.

Do You Know the Condition of What You Hold?

Most archives cannot say. That is the problem: not that the holdings are known to be poorly described, but that the condition of the catalogue as a whole is not known at all.


An archive holds records transferred over generations, described at different times, to different standards, by different hands. Some series are described down to the item. Others carry a title and little else. Digitization adds images faster than descriptions can keep up. Problems usually surface one at a time: a researcher who cannot find a file, a request that takes weeks, a digitized record nobody can search. Until then, nobody could have known how many more there are.


If you pulled a thousand catalogue records at random, what percentage would have a meaningful title, a date, a description, a complete place in the hierarchy and a recorded access status?

Why It Matters for an Archive

An archive's holdings are the permanent memory of a government and its people. As you know, three things follow from that:

  • Permanent: nothing ages out. A record described poorly today stays hard to find for as long as it is kept, which is forever.
  • Public: the catalogue is the only way in. A record that cannot be found through its description might as well not be held.
  • Trusted: courts, historians, journalists and citizens rely on the record being authentic, in context, and correctly identified.

Each of those rests on the repository: the descriptions, the hierarchy that gives every record its context, the digital copies and the access decisions recorded against them. A record is only as usable as its description, and a gap in the catalogue is invisible to everyone searching it.


This matters more as archives adopt AI. AI search and AI assistants are only as reliable as the descriptions they work from, and the gains come from finding issues early: each one corrected improves the next result, and the improvements compound.


See It on Real Records: The US National Archives Live Demo

AITS pointed CTS at catalogue descriptions the US National Archives publishes as open data, checked every one against a set of KPIs, and rolled the results up into one composite Repository Health score. Two pages show the result:

  • The CTS Dashboard: the score at a glance, with the breakdown behind it and the recommended actions. This is what an executive sees.
  • The Health Report: the dimensions, every KPI with how many records passed, the actionable recommendations ranked by the gain each would bring, and where the risk sits series by series.
  • Every record, not a sample: each description was checked as it was loaded, the same way CTS assesses each item as it arrives in an engagement.
  • Seven of the eight dimensions were measured. Security was left out, because everything in the collection is already public.

What this is and what this is not. The score is measured from the published catalogue descriptions, not from the documents themselves, and against KPIs AITS chose for this presentation. The National Archives would choose its own. Nothing was edited, and the National Archives' own systems were not involved. The demo is not endorsed by, or connected with, the US National Archives.


AI That Learns From Your Staff, and Works Under Their Control

CTS is not a fixed set of rules applied to every repository. Its AI is trained on your own records, so it learns what a sound record looks like here. The measuring is automated. The standard being measured against is yours.


It learns how you solve problems. When staff confirm, correct or dismiss a finding, that decision trains the model. CTS learns not only to recognize an issue but how your people resolve it, so the alerts get sharper and the number needing review falls.


You decide how much it does. Every type of issue starts with CTS recommending and a person acting. When you are satisfied it handles a type correctly, you can let it prepare the fix for approval, and later give it standing permission to resolve that type itself. Staff check a sample, every action is logged and reversible, and you can withdraw the permission at any time.


The description stays with the archivist. CTS recommends corrections to repository records: titles, dates, links, duplicates, missing fields. It never alters a record or decides what it means. Appraisal, arrangement and description remain the archivist's.


People stay in charge. CTS learns from your archivists and records staff, and their judgement is what it cannot replace. It takes the repetitive work off their desks and leaves them the review, the exceptions and the decisions.


The repository improves with it. Every issue corrected raises the score, and the trend shows whether the repository is getting healthier or slipping. Better descriptions make the AI more accurate, and a more accurate AI finds the next issue sooner. The two improvements compound.


Your Official Repository Is Never Touched

CTS does not run against the official repository. The archive's environment is replicated in a secure cloud environment hosted in-country, and the AI is trained and run on that replica. It works alongside the systems you already have, with no platform replacement.


Every item is assessed, from the first to the last. The replica starts empty. Your content is loaded into it in bulk, and CTS assesses each item as it arrives. Existing records, newly digitized records and new accessions all go through the same check, so the score covers the whole repository and not a sample.


The official repository remains untouched. Nothing CTS does is destructive, and any result or correction can be compared against the original at any time.


Corrections are made and checked in the replica first. Applying them to the official catalogue remains the archive's decision, through its own change controls.


What the AI Measures in an Archive's Repository

Health is not one property. CTS scores the repository across eight dimensions, each built from KPIs the archive defines and weights. These eight are the starting set AITS recommends, and the ones used in the live demo; each rolls up into the composite score, and each can be opened to see what is pulling the score down.


Content

Does every record have a title of its own within its parent, and is its physical form stated?

Structure

Does every record sit in a complete hierarchy, up to its record group, at a recognized level?

Metadata

Are the required fields complete, and are the dates valid and in order?

Search

Is the title meaningful, is there a description or subject terms, and does a digitized record have searchable text?

Data Quality

Do a record's dates fall within those of its parent, and does each digital copy have its address, type and size recorded?

Security

Do access permissions reflect the sensitivity of the record, including restricted and closed material?

Governance

Are access and use status recorded, and is the custodian named?

AI Readiness

Does the record pass every check an AI assistant relies on to find it and describe it correctly?

AI Is Only as Good as the Records Behind It

Archives have good reasons to adopt AI: natural-language search across the catalogue, transcription of handwritten records, descriptions drafted for the backlog. But AI works from the records it is given, and it does not know what it has not been told.

It cannot find a file whose title is only a number. It will describe a record out of its context if the hierarchy above it is incomplete. It will read a date from a faded page and present it with confidence. It will surface a restricted record if nothing says it is restricted.

A measured repository is what makes archival AI safe to use. With a current health score, you know which collections are ready for AI today, which need work first, and whether each new use is improving the record or degrading it.

AI capabilities can then be introduced one at a time, each with a defined use, human review points, security controls and a measurable result.

What a Healthy Repository Enables

  • Natural-language catalogue search
  • Document classification
  • Information extraction
  • Handwritten record transcription
  • Description drafting for the backlog
  • Duplicate and anomaly identification
  • Record linkage across series
  • Reference request assistance
  • Staff knowledge assistance

How an Engagement Works

Discover

Understand the repository, its content, structure and processes, and agree the KPIs that define a healthy record for this archive.

Assess

Replicate the repository in a secure cloud environment, train the AI on it and run the Health Check. The result is the first score, with the detail behind it.

Prioritize

Rank what to fix first by risk and value, including which collections to describe or digitize first.

Optimize

Correct and monitor continuously. The AI keeps learning, and the score shows that each change left the record better.

An Archive You Can Show Is Sound

The value of an archive lies in the integrity, accessibility and protection of its holdings. Every record is kept to be found. The repository behind the catalogue should be measured.

AITS brings together AI and machine learning, records and information management, and business process experience to give an archive what it has not had before: a current, evidence-based answer to the question of what condition its holdings are in, and a system that keeps that answer true as the holdings grow.

The destination is not simply a newer system. It is an archive that knows the condition of its records, improves them continuously, and can show an auditor how it knows. See it on real records: the CTS Dashboard and the Health Report for the US National Archives live demo.
