Format Locator
The format locator works with format definitions such as pattern matching (regular
expressions and
simple expressions) and
advanced algorithms (Levenshtein and
trigrams). The
format definitions in partnership with
dictionaries and
keywords are used to extract data from documents, without the need to define zones. The locator
runs on a full or partial page read of the document to extract the data using searches that are specific to the data, not the
document layout. The locator evaluates the found alternatives and the data output.
You can add more than one format definition on a single format locator to increase flexibility. This is useful because the format locator searches a document and collects all items that match any of the format definitions. Depending on whether a format matches an entire word or just part of it, a confidence level is assigned. For the calculation of the final confidence, this extraction method also takes keywords into account.
To configure a format locator, add it to the selected class. Open a document set that contains documents for the class before modifying the locator properties. You can then configure the Format Locator by opening the locator properties.
