## Overview

Documents can contain normal fields, table fields, or both. The Supervision tasks associated with a document are dependent on the types of fields it contains. In each of the following scenarios, the field type(s) in a document are pre-defined by the user in the respective Semi-structured layout.

### Documents that only contain table fields

- Table fields are characterized by the fact that each field, or cell, has a relationship with a column header, and each series of related fields constitutes a row.

- Tables do not need to have a standard grid format: if a table has distinct columns, but the individual values in a row don’t share the same alignment, it still qualifies as a Table.

- The Table ID task is the only Supervision task required to identify data on this kind of document.

- Note that a Table ID task will be generated whenever a document contains a table, even if the machine is able to confidently identify the table within the document. This functionality allows you to verify the table’s structure before sending the document to Transcription.

### Documents that only contain normal fields

- Normal fields are text, signatures, and checkbox fields – anything that is not a table field.

- The Field ID task is the only Supervision task required to identify data on these kinds of documents.

- If the machine is able to confidently identify all of the fields on a document, then Hyperscience will not generate a Field ID Supervision task.

### Documents that contain both field types

- Field ID and Table ID are both necessary Supervision tasks in order to identify all of the data on these kinds of documents.

- First, the user will perform Field ID and then they perform Table ID.

- Due to the presence of a table in the document, a Table ID task will always be generated so that you can confirm what the machine has identified before passing the document along to Transcription.
