# CreateDocumentClassifier
<a name="API_CreateDocumentClassifier"></a>

Creates a new document classifier that you can use to categorize documents. To create a classifier, you provide a set of training documents that are labeled with the categories that you want to use. For more information, see [Training classifier models](https://docs.aws.amazon.com/comprehend/latest/dg/training-classifier-model.html) in the Comprehend Developer Guide.

## Request Parameters
<a name="API_CreateDocumentClassifier_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [ClientRequestToken](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-ClientRequestToken"></a>
A unique identifier for the request. If you don't set the client request token, Amazon Comprehend generates one.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.  
Pattern: `^[a-zA-Z0-9-]+$`   
Required: No

 ** [DataAccessRoleArn](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-DataAccessRoleArn"></a>
The Amazon Resource Name (ARN) of the IAM role that grants Amazon Comprehend read access to your input data.  
Type: String  
Length Constraints: Minimum length of 20. Maximum length of 2048.  
Pattern: `arn:aws(-[^:]+)?:iam::[0-9]{12}:role/.+`   
Required: Yes

 ** [DocumentClassifierName](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-DocumentClassifierName"></a>
The name of the document classifier.  
Type: String  
Length Constraints: Maximum length of 63.  
Pattern: `^[a-zA-Z0-9](-*[a-zA-Z0-9])*$`   
Required: Yes

 ** [InputDataConfig](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-InputDataConfig"></a>
Specifies the format and location of the input data for the job.  
Type: [DocumentClassifierInputDataConfig](API_DocumentClassifierInputDataConfig.md) object  
Required: Yes

 ** [LanguageCode](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-LanguageCode"></a>
The language of the input documents. You can specify any of the languages supported by Amazon Comprehend. All documents must be in the same language.  
Type: String  
Valid Values: `en | es | fr | de | it | pt | ar | hi | ja | ko | zh | zh-TW`   
Required: Yes

 ** [Mode](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-Mode"></a>
Indicates the mode in which the classifier will be trained. The classifier can be trained in multi-class (single-label) mode or multi-label mode. Multi-class mode identifies a single class label for each document and multi-label mode identifies one or more class labels for each document. Multiple labels for an individual document are separated by a delimiter. The default delimiter between labels is a pipe (\$1).  
Type: String  
Valid Values: `MULTI_CLASS | MULTI_LABEL`   
Required: No

 ** [ModelKmsKeyId](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-ModelKmsKeyId"></a>
ID for the AWS KMS key that Amazon Comprehend uses to encrypt trained custom models. The ModelKmsKeyId can be either of the following formats:  
+ KMS Key ID: `"1234abcd-12ab-34cd-56ef-1234567890ab"` 
+ Amazon Resource Name (ARN) of a KMS Key: `"arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab"`

Pattern: `^\p{ASCII}+$`   
Required: No

 ** [ModelPolicy](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-ModelPolicy"></a>
The resource-based policy to attach to your custom document classifier model. You can use this policy to allow another AWS account to import your custom model.  
Provide your policy as a JSON body that you enter as a UTF-8 encoded string without line breaks. To provide valid JSON, enclose the attribute names and values in double quotes. If the JSON body is also enclosed in double quotes, then you must escape the double quotes that are inside the policy:  
 `"{\"attribute\": \"value\", \"attribute\": [\"value\"]}"`   
To avoid escaping quotes, you can use single quotes to enclose the policy and double quotes to enclose the JSON names and values:  
 `'{"attribute": "value", "attribute": ["value"]}'`   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 20000.  
Pattern: `[\u0009\u000A\u000D\u0020-\u00FF]+`   
Required: No

 ** [OutputDataConfig](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-OutputDataConfig"></a>

Required: No

 ** [Tags](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-Tags"></a>

Required: No

 ** [VersionName](#API_CreateDocumentClassifier_RequestSyntax) **   <a name="comprehend-CreateDocumentClassifier-request-VersionName"></a>
