# External EN Econ Explanation + Article CPT (512/32)

외부 4개 소스(설명형 + 기사형)를 병합/정제/청킹한 영어 CPT 코퍼스입니다.

## Sources
- `KadamParth/NCERT_Economics_12th` (Explanation)
- `KadamParth/NCERT_Business_Studies_12th` (Explanation)
- `KadamParth/NCERT_Accounting_12th` (Explanation)
- `XJCEO/bloomberg_financial_news_120k` (Article)

## Processing Pipeline
1. Merge target fields only (`Explanation`, `Article`)
2. External cleaning:
- `<|endoftext|>` artifact split/cleanup
- Bloomberg contact boilerplate tail removal
- table/separator noise removal (`====`, `YOY%` 등)
- leading/trailing sentence-fragment trimming
3. Exact dedup
4. Sentence-aware chunking
- tokenizer: `Qwen/Qwen3.5-4B`
- `max_tokens=512`, `overlap_tokens=32`
- docs with any `hard_split` dropped
