Key-Value Pairs Locator
The Key-Value Pairs Locator uses extraction results from a separate AI engine that is pre-trained to find pairs of data; keys and their corresponding values. You can configure the key-value pairs as subfields and then define additional keywords for each subfield. Keywords ensure that a pair is found even if the key differs on different documents.
In order to use this feature it is necessary to enable key-value pair extraction at the class level. This means that if you want to use this feature for multiple classes, the setting must be enabled for each class.
Once key-value pair extraction is enabled you can add as many subfields for key-value pairs as you want. You can also add additional keywords for each subfield, if needed.
For example, additional keywords for a Customer Number can include Customer No, Policy Number, Account Number, Customer ID, Customer Code, etc.
You can add additional keywords manually or you can reference a dictionary that contains all relevant keywords. A dictionary is useful when there are more than ten additional keywords for a subfield, or you want to include keywords for multiple languages.
If you export a Key-Value Pairs Locator and it includes one or more keyword dictionaries, those dictionaries are not included in the locator export. Because of this it is necessary to export the dictionaries separately. If you do not import these dictionaries, an error message is displayed when the locator is imported stating that the dictionaries are missing.
Currently, this functionality works best for Western languages. As a result, the results for other languages such as Chinese or right-to-left languages cannot be guaranteed.
