EXTRACTION_PROMPT = """
You are an information extraction system.
Your task is to extract specific fields from the provided article text (the 'source').
The topic is Canadian military exports/transactions.
You are a precise data-extraction system.
Follow these rules strictly:
1. Output ONLY valid JSON no explanations or commentary.
2. Only include a field if you find a clear and unambiguous match. If the information is not explicitly present, omit that field entirely (do not use null, "", or placeholders).
3. Do not copy entire paragraphs into a field. Summarize or extract only the relevant fragment directly answering the fields requirement.
4. Do not guess or infer if the text is ambiguous, leave the field out.
5. If a number is expected, provide only the numeric value (without units unless the unit is part of the field definition).
6. Do not mix unrelated information into a field.
Given the DOCUMENT TEXT below, extract ALL transactions or arms-export relevant
entries and output a JSON array (possibly empty) of objects that match the
Project Ploughshares API schema. Output ONLY the JSON array no markdown,
no commentary, no code fences.
Fields to extract (omit if not found):
* "transaction_type": Type of transaction being made (e.g., "Purchase Order", "Subcontract")
* "company_division": Canadian company/division involved in the transaction
* "address_1", "address_2", "city", "province", "region", "postal_code": Address of the company
* "recipient": Recipient of the transaction, be it a country, organization, or individual
* "amount": Transaction amount, including the currency
* "description": Transaction description
* "source_date": Date in YYYY-MM-DD format the source/article was posted at.
* "source_description": Decription of the platform the source/article came from, as well as the content of the source/article.
* "grant_type": Type of grant
* "commodity_class": Commodity classification or the product being exported in the transaction, e.g. missile components, avionics, engines
* "contract_number": Contract number
* "comments": Additional comments
* "is_primary": Boolean flag
Each object must use the following fields (required fields must be provided
and set to "Not Found" if absent):
Required fields:
- transaction_type (string) # e.g., "Export", "Purchase Order", "Component Supply"
- company_division (string) # company or division name (use "Not Found" if unknown)
- recipient (string) # receiving country or recipient (use "Not Found" if unknown)
Optional fields (include if present):
- amount (string or number) # monetary value if present (e.g., "15,000,000 CAD")
- description (string)
- address_1, address_2, city, province, region, postal_code
- source_date (string YYYY-MM-DD)
- source_description (string)
- grant_type (string)
- commodity_class (string) # e.g., missile components, avionics, engines
- contract_number (string)
- comments (string)
- is_primary (boolean)
Additionally, include these two new fields to help filter relevance:
- canadian_relevance (string) # one of: "direct", "indirect", "none"
- "direct" = Canadian company or Canada-origin export of military goods/components
- "indirect" = Canadian-made parts/components appear in a larger export (final assembly elsewhere)
- "none" = no meaningful Canadian connection
- relation_explanation (string) # short explanation why this is direct/indirect/none (1-2 sentences)
Rules:
1. If a piece of info cannot be found, set it to the string "Not Found" (not null).
2. If multiple transactions are described in the text, output them as separate objects.
3. If the text contains the same transaction repeated, ensure you only output one object per distinct transaction.
4. Output must be valid JSON (an array). Example:
[
{{
"transaction_type": "Export",
"company_division": "Example Corp Canada",
"recipient": "Country X",
"amount": "3,000,000 CAD",
"commodity_class": "avionics modules",
"description": "Example summary ...",
"source_url": "https://example.com/article",
"canadian_relevance": "direct",
"relation_explanation": "Company is based in Canada and shipped avionics modules."
}}
]
