Understanding LabelExtraction

The label extraction class is returned by many of the helper functions that a Stream Prediction returns, and represents a single extraction that the platform has made. This section contains a summary of what data it contains.For more details, see The anatomy of an extraction.

Properties

Property	Description
LabelExtraction.Name	The extraction's name indicates its primary topic. For example, an extraction could be called "Address Change" to signify that its main focus is on changing addresses.
LabelExtraction.OccurenceConfidence	This is the confidence value associated with the extraction.
LabelExtraction.Fields	This is the list of fields that have been extracted for the current extraction.

Helper functions

Just like withthe StreamResult class, you typically won't need to interact with these properties directly. There are a set of helper functions that make it easy to access the data you need:

FieldExists

FieldExists(string name)

Returns: bool

This function lets you determine whether a given field exists for the current extraction.

GetFieldValue

GetFieldValue(string name)

Returns: string

This function returns the value for the given field.

note

If the field does not exist, then an empty string will be returned.

GetField

GetField(string name)

Returns: Field.

This function returns the field with the given name

note

Most of the time you want to use GetFieldValue instead.
