Document Understanding Activities

ClassifierCodeActivity Class
ClassifierCodeActivity is an abstract class that implements both the IClassifierActivity interface and the CodeActivity abstract class, vital for creating a compatible CodeActivity for document classification.
- Namespace:
UiPath.DocumentProcessing.Contracts.Classification - Assembly:
UiPath.DocumentProcessing.Contracts
An abstract class that implements the
UiPath.DocumentProcessing.Contracts.Classification.IClassifierActivity
interface and the
System.Activities.CodeActivity
abstract class.
This class must be implemented in order to
construct a
CodeActivity for
document classification that is compatible with
the Classify Document Scope
activity and the document processing
infrastructure.
In order to implement this abstract class, the
Execute(CodeActivityContext
context) method must be overridden.
All the defined InArguments are automatically populated by the Classify Document Scope activity for all child activities.
The InArguments contain the following information:
- Information about the document that is to be classified, specifically the original file path, the text version, and the document object model.
- Information about the document types expected to be understood and processed by the classifier activity. These document types are set by the Classify Document Scope activity after their configuration in the Configure Classifiers wizard of the scope activity.
The OutArgument contains a list of
classification results, in a
ClassifierResult.
For example, if a classifier can classify an
entire file as either a contract or an annex, then
the
ClassifierResult should
contain a single entry in the
Classifications list. This entry
should reflect the highest confidence
classification, with the
ResultsDocumentBounds
encompassing the entire document.
If a classifier can classify segments of a file
as either a contract or an annex, then the
ClassifierResult should contain
multiple entries in the
Classifications list, matching
the number of identified parts. These entries
should each have its own
ResultsDocumentBounds. The page
ranges for each should be disjunctive.
Constructors
ClassifierCodeActivity()
- The protected default constructor.
