Which locator to use for table extraction?
There ware two different locator methods for extracting tables on a document.
- Table Locator
-
This locator method is fine-tuned for invoices with a single table of line items that can span multiple pages.
Any additional tables after the first table are ignored.
This locator is available for online learning.
- Advanced Table Locator
-
This locator method uses a separate recognition engine that extracts and assigns a table type to every table on a document. With the aid of design-time training documents, this locator identifies specific table types to extract, no matter where the table is located on a document.
This locator is not available for online learning. All training must be done during design-time.
This means that if you are processing an invoice with a single table of list items, use a Table Locator. If you are processing a document with multiple tables, and want to extract data from one or more tables, use the Advanced Table Locator, one for each table in the document.
