{'service': 'train', 'act': 'inform', 'slot_name': 'time', 'value': '17 minutes'} {'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': '8'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '09:50'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': ' 23:50'} {'service': 'train', 'act': 'select', 'slot_name': 'none', 'value': 'none'}
