FineWeb2-IR
Multilingual IR training set built by generating search-style queries from FineWeb-Edu (English) and FineWeb2-HQ (20 additional languages) using the model hotchpotch/query-crafter-multilingual. Each of the 21 languages below has roughly 3M (query, text) pairs plus validation (2k) and test (30k) splits. Use it for multilingual IR training, reranking, and evaluation.

Dataset construction
- Source corpora
- English: HuggingFaceFW/fineweb-edu.
- Non-English: HuggingFaceFW/fineweb-2 / FineWeb2-HQ.
- Cleaning & filtering: remove rows with missing text, cap text length, keep passages whose token count (Qwen3-1.7B tokenizer) falls in a per-language range.
- Query generation:
- Prompt format:
system: language=<lang>\ntype=<instruction>,user: <passage>. - Model:
hotchpotch/query-crafter-multilingualvia vLLM (T=0, top-p=0.95, max_new_tokens=128). - Instruction types (7):
keywords,query,title,faq,summary,synonym_keywords,alt_query. - Rotation weights: 5× for the first five types, 1× for
synonym_keywordsandalt_query(so these two are rarer by design).
- Prompt format:
- Post-filtering & split: drop empty/"NONE" queries and queries ≥50 tokens (Greek cap 70); stratified split by
type: validation 2,000, test 30,000, train = remainder. Columns kept:query,text,type,query_token_count,text_token_count,id,original_row_id,date,dump,file_path,score. - Deduplication (no-dup release): within each split, remove any row whose
queryortextduplicates a previously seenqueryortext(afterstrip()), ensuring all queries and documents are unique within the split.
Hard negatives (train/test)
- For each language subset, all texts are embedded with BGE-M3 and indexed for ANN search.
- Each query embedding retrieves the top 200 nearest texts excluding the paired positive; their IDs go to
hard_negativesand cosine-similarity scores tohard_negatives_score. - The
scorecolumn is the original FineWeb quality score, not a query–text similarity score.
