Ishigaki-IDS-Bench

Ishigaki-IDS-Bench is a bilingual benchmark for generating buildingSMART IDS 1.0 XML from user-facing building requirements.

Data Format

Each row uses the common conversational messages format:

{
  "id": "row-0001",
  "messages": [
    {"role": "user", "content": "..."},
    {"role": "assistant", "content": "..."}
  ],
  "language": "ja",
  "input_format": "natural_language",
  "turn_type": "single_turn",
  "domain": "architectural",
  "ifc_versions": ["IFC4"]
}

The final assistant message is the gold IDS XML. The evaluation input is messages[:-1].

Fields

• id: example identifier.
• messages: multi-turn conversation in role/content format.
• language: ja or en.
• input_format: natural_language or csv.
• turn_type: single_turn or multi_turn.
• domain: architectural, structural, mep, or general.
• ifc_versions: target IFC version labels.
