FinePhrase Gov Reranker Hard K10 v1

Hard reranker dataset derived from HuggingFaceFW/finephrase for Irish-government-like search.

Each row is a grouped reranker example:

• —one query
• —one relevant passage from a public-sector page
• —nine hard negatives from the same filtered gov-like domain pool

The candidate set is fixed at 10, matching the current serving target of reranking only the top 10 candidates after first-stage retrieval / RRF.

Source filtering

Rows are filtered to public-service and Irish government related hosts such as:

• —gov.ie
• —citizensinformation.ie
• —hse.ie
• —oireachtas.ie
• —related historical/government subdomains captured in the source snapshot

Construction

• —source dataset: HuggingFaceFW/finephrase

• —negatives: lexical shortlist followed by teacher-selected hard negatives
• —teacher used for hard-negative selection: temsa/search-reranker-broad-v1 q8

Split sizes
