CSuggestive similarity

Evidence tier

Echo patterns are similarity-based hypotheses, not proof of causation. Open the sources and evaluate the linkage yourself.

Evidence Scorecard

A single score cannot prove an echo. This card triangulates semantic, temporal, and linkage evidence.

Suggestive similarity

Semantic

Strong semantic alignment

Temporal

Global precedent precedes Korea

Linkage

No recorded linkage

Tier C — Suggestive similarity — semantic or keyword overlap + plausible timing

Multilingual semantic similarity

cosine similarity (method detail)0.806

Computed with intfloat/multilingual-e5-small multilingual embeddings. Display score is a calibrated mapping of the raw cross-lingual cosine (0.806); higher means closer meaning. Reflects semantic similarity, not proof of causation.

Could also be…

•Parallel domestic policy development is possible.
•Industry or market pressure may have driven similar language.
•A common external shock (e.g., financial crisis, pandemic) could explain parallel adoption.

Matched concepts: Polar Code ↔ 극지; polar waters ↔ 극지활동; ships operating ↔ 쇄빙선

Cross-lingual similarity 48/100 (multilingual e5 embedding) — a computed signal, not proof.

Similarity type: treaty implementation with domestic framework law

Caveat: semantic similarity only — this tier records a hypothesis, not proof of causal influence.

Original (Global)

The IMO International Code for Ships Operating^③ in Polar Waters^② (Polar Code^①), mandatory under SOLAS and MARPOL, entered into force on 1 January 2017, requiring ships in Arctic and Antarctic waters to hold Polar Ship Certificates (Categories A, B, or C), carry a Polar Water Operational Manual, meet ice-strengthened construction standards, and comply with discharge restrictions including a prohibition on oil discharge into Arctic waters and, from July 2024, a ban on heavy fuel oil use under MARPOL Annex I Regulation 43A.

Echo (Korea)

한국은 2021년 4월 13일 제정된 「극지활동^②진흥법」(법률 제18055호, 시행 2021. 10. 14.)을 통해 해양수산부 장관이 5년 단위 극지활동^②진흥 기본계획을 수립하도록 의무화하고(제6조), 쇄빙선^③ 등 극지^① 인프라 확보 및 북극항로 개발을 국가 책무로 규정하였다(제1차 기본계획 2023~2027). 또한 「선박안전법」 시행규칙에 따른 극지^①운항기준을 통해 IMO 극지^①코드의 극지^①운항선박 증서(Polar Ship Certificate) 발급 등 의무사항을 국내 이행하고 있다. 2025년 7월 29일에는 해양수산부·극지^①연구소 주관으로 한화오션과 IACS PC3급 LNG-MGO 이중연료 전기추진 쇄빙연구선(총톤수 1만 6,560톤, 2029년 12월 인도 예정) 건조 계약을 체결하여 극지^①코드 기술기준을 직접 적용하고 있다.

Score Guide

Confidence — Editorial judgment, now shown as a confidence tier (A–D) based on semantic, temporal, and linkage evidence. Not proof of causation.

Echo Strength — Metadata completeness score. Rewards verified sources, paired links, explicit dates, keyword diversity, and origin tags.

Vocabulary Overlap — Heuristic score measuring shared tokens between global and Korean texts. Reflects loanwords and repeated terms, not meaning across languages.
