Note: If you want to use a Dedicated AI Engine make sure you have purchased the feature before you start the training process.
1. Always use Magic Grid to annotate the structured line items tables.
Structured tables are tables where data is placed in separate columns, one data type per column, each line item in a separate row. When using a Magic Grid, drag the grid lines over the data itself. See our user guide article or the video below on how to use Rossum’s Magic Grid in more detail:
2. For semi-structured and unstructured tables, use the combination of Magic Grid and point-and-click approach.
Semi-structured and unstructured tables are tables where one data type is placed within another data type, or the data you need to have extracted flow across more columns so it couldn’t be included in the Magic Grid. For these cases, use Magic Grid as shown in the video above, for all the data that can be extracted using Magic Grid. For the rest of the data, use your mouse to extract the data by pointing on them and clicking on the bounding box around the data or drawing it around the data from scratch.
Of course, selecting all the values manually is very tedious and time consuming. Therefore, Rossum’s AI Engine can be configured to learn from the user’s feedback immediately after clicking on the values in the first row. Based on the user’s input we can already complete other values in the columns of the table. Read more how to capture nested values in complex tables.
Moreover, the AI Engine can improve itself in the long term based on the user feedback.
If capturing data from such complex tables is already bothering you, do not hesitate and contact us on firstname.lastname@example.org. We would happily make you part of our early adopters group so that we could conquer this challenge together.
Note: the configuration mentioned in the video is not present on your Rossum account by default. To find out more about the configuration, see this article. The point-and-click approach for annotating can be applied without this configuration.
3. Place the columns as close to the original table as possible.
When using Magic Grid, put the grid lines over the table lines rather than putting them too close or too far from the table line.
