An example of 'validation' looks as follows.

This example was too long and was cropped:

{
    "phase": 1,
    "question": "How would you answer a second test question?",
    "sql": {
        "agg": 0,
        "conds": {
            "column_index": [2],
            "condition": ["Some Entity"],
            "operator_index": [0]
        },
        "human_readable": "SELECT Header1 FROM table WHERE Another Header = Some Entity",
        "sel": 0
    },
    "table": "{\"caption\": \"L\", \"header\": [\"Header1\", \"Header 2\", \"Another Header\"], \"id\": \"1-10015132-9\", \"name\": \"table_10015132_11\", \"page_i..."
}

Data Fields

The data fields are the same among all splits.

default

• phase: a int32 feature.
• question: a string feature.
• header: a list of string features.
• page_title: a string feature.
• page_id: a string feature.
• types: a list of string features.
• id: a string feature.
• section_title: a string feature.
• caption: a string feature.
• rows: a dictionary feature containing:
  • feature: a string feature.
• name: a string feature.
• human_readable: a string feature.
• sel: a int32 feature.
• agg: a int32 feature.
• conds: a dictionary feature containing:
  • column_index: a int32 feature.
  • operator_index: a int32 feature.
