Key takeaways

  • Approve the source version before approving extracted fields.
  • Preserve qualifications, options and unresolved subjects alongside values.
  • Require a separate decision before extracted terms drive payments or external instructions.

Select the source before reviewing the output

A negotiation chain may contain offers, counteroffers, broker summaries and corrected recaps. The extraction workflow should ask which document or message is being processed and what status the authorised desk assigns to it. The newest timestamp alone is not a reliable substitute for that decision.

Show the source identity, revision and relevant attachments at the top of the review. If the recap refers to earlier wording, identify the referenced document and whether it has been retrieved. A parser should not fill missing provisions from a similar fixture merely because the text says “as before”.

Keep draft and approved sources distinguishable in the data model. This allows useful early extraction without implying that every proposed term is agreed. The reviewer can then approve the extraction's fidelity while leaving the commercial status appropriately unresolved.

Preserve commercial expressions as structured groups

Extract a rate with its basis, a quantity with its option language and a date with its relevant qualification. Treating these as isolated fields can produce a clean-looking record that loses the commercial meaning of the original expression.

Provide the original phrase beside the normalised value. For a port range, retain the range rather than selecting one familiar location. For a notice or payment provision, identify the source passage and route interpretation questions to the authorised reviewer instead of converting uncertain wording into a rigid workflow rule.

The extraction schema should support “not stated”, “ambiguous” and “requires referenced document”. Those states are useful outputs. A compulsory field that forces the model to invent a value can be more dangerous than an incomplete record that honestly identifies the missing information.

Separate factual checking from commercial approval

An analyst can check whether the extracted cargo quantity matches the selected recap. The responsible broker decides whether that recap reflects the approved negotiation position. A contractual reviewer assesses disputed wording or formation questions. These tasks may involve the same individual in a small desk, but they remain distinct decisions.

Record the scope of each approval. “Extraction checked” should not be displayed as “fixture confirmed”. Similarly, a legal review of one clause should not automatically approve every operational field or attachment in the record.

When an approved source changes, invalidate only the affected decisions where the implementation permits a reliable comparison. Show the change clearly. Do not force reviewers to reread unrelated fields, but do not carry an earlier approval over a material amendment without attention.

Use a recap extraction authority map

Use the map to design the interface and notifications. An extraction exception about a misspelled vessel identifier should not be sent to the same queue as a disputed subject-lifting message simply because both involve text.

Keep a clear route for the reviewer to request source clarification. The workflow should help the reviewer ask a precise question and attach the relevant passage, rather than encourage them to guess in order to complete the record.

Keep model suggestions separate from authority

The system may suggest that a message appears to lift a subject or amend a term. Present that as a proposed classification with supporting text. It should not change the fixture's commercial status unless the designated person approves the interpretation through the established process.

OWASP's excessive-agency guidance highlights risks from giving AI systems more action capability than their task requires. For recap extraction, a practical design response is to keep parsing separate from authority to issue contractual communications or payment instructions. OWASP excessive-agency guidance.

The implementation team should enforce those boundaries in the application, not rely solely on an instruction telling the model to be careful. Commercial staff should test the result using scenarios where a source message asks for an action outside the parser's role.

Design the handover around unresolved decisions

An approved extraction can produce a useful handover containing confirmed fields, source links and outstanding questions. Keep the unresolved items prominent and assign owners. A blank clause reference or unverified payment detail should not disappear because the summary is intended to be concise.

Before a downstream system uses a field, define the required approval status. A voyage planner may work with a clearly labelled provisional port range, while finance may need a separately verified payment basis. The same data can support different tasks with different authority requirements.

Keep the released handover version and later amendments. If a term changes, tell the affected team what action or assumption needs review. Merely updating the database may leave an operator following an earlier exported instruction.

Fictional case: a subject-lifting phrase in quoted history

In this fictional case, a recap email includes a quoted earlier message saying a terminal subject had been lifted for a different proposed vessel. The extractor applies that phrase to the current vessel and suggests a fully confirmed fixture status.

The reviewer sees the source passage and notices the vessel mismatch. The status suggestion is rejected and the responsible broker clarifies the current subject position. The corrected record preserves the recap terms while leaving the unresolved subject visible.

The workflow succeeds because approval is attached to the commercial decision, not simply to whether the model produced well-formed data. Accurate formatting would not have prevented the mistaken interpretation on its own.

Common mistakes

Do not treat the latest email as automatically authoritative or use a field checker to decide whether a fixture is binding. Another mistake is extracting headline values while dropping options, qualifications and referenced documents.

Avoid a single “approved” badge that covers source selection, extraction and operational release. Finally, do not let a corrected database field silently replace an instruction already distributed. Notify the responsible users and retain the version history.

Frequently asked questions

Can extraction decide whether subjects are lifted?

It can identify relevant wording and propose a classification, but the authorised desk should determine the status using the actual communications. Quoted text, changed vessels and conditional responses can make a simple phrase misleading. Preserve the evidence beside the proposed decision.

Does every term need legal review?

Routine source-to-field checking can be handled by trained staff within their authority. Material ambiguity, disputed wording and legal-effect questions should follow the appropriate review route. The purpose of the authority map is to send each question to the right person, not escalate every clerical check.

What should happen when a referenced document is missing?

Mark the affected fields as dependent on that document and assign retrieval. Do not infer the content from a similar fixture or a model's general knowledge. The handover should show the gap until an authorised source is available and reviewed.

Can approved fields feed other systems automatically?

Only within an agreed action policy that identifies the required approval and destination. A field approved for planning may not be sufficient for payment or external communication. Keep the downstream use explicit and preserve the source version behind the transferred data.
