Attributes
| Attribute | API Type | Default | Description |
|---|---|---|---|
| Name | String | Specifies the name of the object. This name can be used to reference this object from anywhere else in the program. This is a required property | |
| TermExtractionColumn | String | This value specifies the name of the term extraction column. This is a required property | |
| CaseSensitiveTermExtraction | Boolean | False | This value specifies whether the Term Extraction process is case sensitive. The default value is False. |
| ConnectionName | AstOleDbConnectionNode | This value specifies the name of the OLE DB connection that is used to connect to the exclusion term table. This references an existing definiton. | |
| LocaleId | Language | Inherited | This value specifies which locale is used by the dataflow task. |
| ScoreOutputColumn | String | "Score" | This value specifies the name of the dataflow column to use for the score output. The default value is "Score". |
| ScoreType | TermExtractionTransformScoreType | Frequency | This value specifies what kind of score is associated with an extracted term. The default value is that the frequency of a term is used as the score. |
| TermFrequencyThreshold | Int32 | 2 | Specifies the frequency threshold above which a term is extracted. |
| TermMaxLength | Int32 | 12 | This value specifies the maximum number of words allowed in a term. The default value is 12. |
| TermOutputColumn | String | "Term" | This value specifies the name of the dataflow column to use for the term output. The default value is "Term". |
| TermType | TermExtractionTransformTermType | NounAndNounPhrase | This value specifies the type of terms to extract. The default value is that noun and noun phrases are extracted. |
| ValidateExternalMetadata | Boolean | true | This value specifies whether the data flow transformation is validated against columns that originated in external data sources. When server assets such as tables and stored procedures are created during processing, ValidateExternalMetadata is normally set to False, which prevents validation from completing at compile time. |

| Child | API Type | Description |
|---|---|---|
| <ErrorHandling /> | AstComponentErrorHandlingNode | Specifies the error handling defaults to apply to an entire component |
| <ExclusionTermTableColumnInput /> | AstTableColumnResourceNode | This resource references a column from a table in the model. |
| <ExclusionTermExternalTableColumnInput /> | AstUnmanagedTableColumnResourceNode | This resource references a column and table that are not included in the model. |
| <InputPath /> | AstDataflowInputPathNode | AstDataflowInputPathNode is used to model input paths in a SQL Server Integration Services dataflow task. Connections are made by referencing an appropriate output path. |

| Child | API Type | Description |
|---|---|---|
| <Annotations> <Annotation /> </Annotations> | AstAnnotationNode | This is a collection of annotation items that can be used to specify documentation, tags, or other information. Annotations are particularly useful for storing information about nodes that can be used by BimlScript code. |
| <DataflowOverrides> Multiple Choices... </DataflowOverrides> | AstDataflowOverrideNode | Provides a collection of objects to override properties of the component, its input paths, its output paths, and its consituent dataflow columns. |
