Table Identification
During Table Identification Supervision, keyers use the Template Tool and keyboard shortcuts to quickly identify all table cells. To maximize the benefits of using the tool and keyboard shortcuts, we recommend following the best practices listed below.
Using the Template Tool
When choosing a template row, consider all pages
If your document has multiple pages, it may contain tables that share a column schema and expected data types for each column. In these cases, your template row can come from any of these identically formatted tables. We will use that row to predict the placement of cells in all of the tables in the document.
If the table's first row has empty cells, we recommend choosing a different row as a template row. You should choose a template row whose columns have values and at the same time, these values are the largest in the table.
Adjust row height before adding a new bounding box
When you add a new bounding box, the system automatically chooses the row for the box and adjusts the row's height as described in Table ID Supervision. To increase the likelihood of the box being placed in your intended row, adjust the height of the row to fit the content that will be included in the box before adding the box.
Auto-annotate missing cells
The target button (​​
) on the top of the column label can help auto-annotate any cells that may have been left unidentified in a particular column. We recommend using this button in the following cases:
When a user manually created rows that the machine had failed to identify. To auto-identify missing cells from the newly created rows, the user can click the target button (​​
) for each column.When a user manually deleted all rows, created new rows from scratch, and annotated a single row. To auto-identify missing cells from the rest of the rows, the user can click the target button (
​​) for each column.
Keyboard shortcuts
Split row
When there are unidentified rows in a table, to identify them more quickly, you can:
Extend the table boundary to the bottom of the table.
Separate the table into individual rows by pressing S on the keyboard and then clicking each place where a row boundary should exist.
This method avoids the need for continuously clicking the + button at the bottom of the last row and constantly adjusting row boundaries.
Select multiple bounding boxes
To select multiple bounding boxes:
Hold Command for Mac or Control for Windows, and click the top-most and then the bottom-most row of a specific column.
Drag the edge boundary until every row’s cell contents are fully captured by the selection highlighting.
We recommend selecting multiple bounding boxes that are part of the same column when many bounding boxes on a page are not fully captured.
Toggle between columns
To toggle between table columns more quickly, we recommend using the following keyboard shortcuts:
To select the previous column, press W.
To select the next column, press E.
Toggle labels visibility
Column labels can sometimes get in the way of annotations or document readability. When needed, we recommend pressing Command + I for Mac or Control + I for Windows to make these labels invisible.
Table Transcription
During Table Transcription, keyers can sometimes have difficulties finding cells that are pending transcription or finding transcribed cells that need to be reviewed. To save time when navigating to different cells, we recommend following the best practices listed below.
Go to next cell
If a table contains many columns, and you zoom in on a document, you may have difficulties finding the next cell in the table during Table Transcription. We recommend pressing Tab to automatically go to the next cell.
Go to next empty cell
If a table contains many cells and most of them have already been transcribed, you may have difficulties finding all cells that do not have a transcription. We recommend pressing Control + E to automatically go to the next empty cell.
