Group Index
The group index can be used to indicate that field values should have some sort
of identifiable geometric relationship with each other. For example, some items
on a document, like zip code and city name, will be geometrically closely related
and can be grouped.
You can define up to five groups by simply assigning a group index to one or
more fields in the field list. If grouped fields on the document are not closely
related, a penalty is applied to decrease the confidence.
Those fields that are assigned to a group are then listed in the Group properties
area, where you can determine further settings for the group.
Distance
Use this property to specify the expected proximity of the elements of a field. For
example, a company name frequently consists of several single words on the
same line, as in SampleCompany Inc. In this case, you can set the distance
property to same line by selecting it from the list.
Importance
Select the level of importance for the field: normal, low, very low, high, and must
exist. This setting indicates how critical the existence of the value is. For example,
if a value for Country is of low importance, there will be minimal impact to the
confidence if it is not found on the document.
Replace
If this option is selected, the results will not use the text actually found on the
document. Instead the extracted text will be replaced by the corresponding value
from the database. This is useful since the database records are located using a
fault tolerant technology that is able to ignore most OCR and typing errors. Most
of the time, you will want the original record from the database to be used as the
result rather than the sometimes incorrect data from the document. This option is
selected by default.
Group properties
The Group properties list shows the groups and the fields that are assigned to this
group, if any.
For each group you can define a distance attribute. This is similar to the distance
setting for the fields, but it applies to the entire group. For example, if you group Last
Name and First Name, the distance for this group should be set to very close since
the member fields are likely to be immediately adjacent to each other on the
document.
