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
