How to tell the document types apart. Titles are often missing, renamed, or misread by OCR, so rely on the fields, not on the title.
- invoice: a request for payment. Has a unit price column and an amount column, a total amount in a currency, and usually payment terms or trade terms such as CIF or FOB.
- packing_list: describes how the goods are packed. Has case or carton numbers, net weight, gross weight and measurement (M3). It has no unit price and no amount. It may be titled "Weight and Measurement List" or similar.
- bill_of_lading: issued by a carrier. Has Shipper, Consignee, Notify Party, vessel and voyage, port of loading, port of discharge, container and seal numbers, "shipped on board", the number of original B/Ls, and a clause about surrendering an original.
- certificate_of_origin: numbered boxes for exporter, importer, transport details and country of origin, a declaration by the exporter, and a certification by a chamber of commerce or authority.
- insurance_policy: issued by an insurer. Has the assured, amount insured, conditions such as Institute Cargo Clauses, and where claims are payable.
- blank: no lines at all, or only a few stray characters such as "|", "_", "." or a single letter left by stamps and ruled lines. A page with a few meaningless fragments is still blank.
- other: a readable page that is none of the above, such as a fax cover sheet or a printed e-mail.
Continuation pages: the second and later pages of an invoice or packing list often have no title and no header. They start directly with table rows and end with a total or a signature. Decide their type from the columns (prices and amounts mean invoice; weights and measurements mean packing_list).
OCR noise: "0" and "O", "1" and "I" or "L" are often confused. Stamps such as "RECEIVED" and handwritten notes may be mixed in. Ignore them.

# （日本語訳）
# 書類種別の見分け方。タイトルは記載がない場合や、別名になっている場合、OCR で誤読されている場合が多いため、タイトルではなく各項目（フィールド）を手がかりに判断すること。
# - invoice: 支払請求書。単価列と金額列、通貨単位付きの合計金額があり、通常は CIF や FOB などの貿易条件や支払条件が含まれる。
# - packing_list: 貨物の梱包状態を示す。ケース番号やカートン番号、正味重量、総重量、容積（M3）がある。単価や金額はなく、「Weight and Measurement List」などの別名が付くこともある。
# - bill_of_lading: 運送人が発行。荷送人、荷受人、着荷通知先、本船名・航海番号、積込港、揚地港、コンテナ・シール番号、「shipped on board」表記、オリジナル B/L の発行通数、およびオリジナル原本の提出に関する約款がある。
# - certificate_of_origin: 輸出者、輸入者、輸送詳細、原産国が記載された番号付きの枠があり、輸出者による宣誓文と、商工会議所または公的機関による証明文がある。
# - insurance_policy: 保険会社が発行。被保険者、保険金額、協会貨物約款などの保険条件、保険金支払地がある。
# - blank: 行が全くないか、スタンプや罫線に由来する「|」「_」「.」などのゴミ文字や1文字の文字断片のみ。意味をなさない少数の断片しかないページも空白とみなす。
# - other: 上記のいずれにも該当しない、内容が読み取れるページ（FAX 送付状や印刷された電子メールなど）。
# 続きページ: インボイスやパッキングリストの2ページ目以降は、タイトルやヘッダーがないことが多い。表の行から直接始まり、合計やサインで終わる。列の内容から種別を判断する（価格と金額があれば invoice、重量と容積があれば packing_list）。
# OCR ノイズ: 「0」と「O」、「1」と「I」または「L」は混同されやすい。「RECEIVED」などのスタンプや手書きメモが混ざり込んでいる場合があるが、無視すること。
