Fetch Abstract to KB

Core Goal

• Provide only two DB operations:
  1. Fetch DOI candidates from journals.
  2. Batch update abstract by DOI.

Required Environment

• KB_DB_HOST
• KB_DB_PORT
• KB_DB_NAME
• KB_DB_USER
• KB_DB_PASSWORD

Workflow

1. Fetch DOI list (default 10 rows):

python3 scripts/fetch_abstract_to_kb.py fetch-doi

2. Optionally override row limit:

python3 scripts/fetch_abstract_to_kb.py fetch-doi --limit 10

3. Prepare JSON input for batch update (one of the two formats):

[
  {"doi": "10.1000/a", "abstract": "text A"},
  {"doi": "10.1000/b", "abstract": "text B"}
]

or

{
  "10.1000/a": "text A",
  "10.1000/b": "text B"
}

4. Batch write abstract by DOI:

python3 scripts/fetch_abstract_to_kb.py write-abstracts --input abstracts.json

Query/Write Contract

• Fetch filter:
  • doi not empty
  • author not empty (fall back to authors when author is unavailable)
  • abstract empty (NULL or blank)
• Fetch order:
  • ORDER BY created_at DESC NULLS LAST
• Fetch default limit:
  • 10
• Write guard:
  • Update only when target row abstract is still empty.
