Document Understanding 活动

描述​

• 包含基于关键字的文档分类算法，可针对具有重复标题的文件进行分类。
• Classifies a document based on a given training set, found in a specified file, if used inside the Classify Document Scope activity.

配置​

设计器面板​

• LearningFilePath - The full path to the file containing the classifier data. This field supports only strings and String variables.

  备注：

  Only one of the above parameters can be set at a time. You can use either the LearningData string or the LearningFilePath string.

  The LearningFilePath specifies the locations from where to retrieve the classifier data.

  The LearningData contains the actual information of that classifier.

属性面板​

• “显示名称”- 活动的显示名称。

• LearningData - The string containing the serialized classifier data. This field supports only strings and String variables.

• LearningFilePath - The full path to the file containing the classifier data. This field supports only strings and String variables.

  备注：

  Only one of the above parameters can be set at a time. You can use either the LearningData string or the LearningFilePath string.

  The LearningFilePath specifies the locations from where to retrieve the classifier data.

  The LearningData contains the actual information of that classifier.

• “私有”- 选中后将不再以“Verbose”级别记录变量和参数的值。

  备注：

  The best practice is to create an empty .json file at that location, then use its name in the LearningFilePath field.

使用“管理学习”向导​

1. Add a Keyword Based Classifier or Keyword Based Classifier Trainer activity to your workflow.

2. Configure your Keyword Based Classifier activity by adding the path of a .json file. Take the following information into consideration, when configuring the classifier:

   • If no path is provided and the Manage Learning option is selected, then a pop-up is displayed, asking for a Learning File Path input. Once the path is provided, the wizard opens.
   • 可以添加变量而不是 .json 文件，但是，由于向导无法将学习模式应用于学习数据变量，因此它会要求您提供可编辑的特定文件路径。

3. Select Manage Learning.

   The Manage Keyword Based Classifier Learning wizard window opens.

   Figure 1. The Manage Keyword Based Classifier Learning wizard overview

   

4. If no path is provided and the Manage Learning option is selected, then a pop-up is displayed, asking for a Learning File Path. Once the path is provided, the wizard opens.

   Figure 2. The Warning pop-up displayed if no path is provided and the Manage Learning option is selected

   

   备注：

   即使没有可用的 .json 文件，您也可以直接将新的 .json 文件的名称添加到活动中，系统会在指定的文件夹中自动创建 .json 文件。

为文档类型添加关键字​

1. Select Add new keyword set to add an extra field to that category.
2. Select the remove icon, to remove the field and its keywords.
3. Select Save to save your wizard configuration. You can find all the added values in the .json file of the project.
   备注：

   根据 Visual Basic 约定（双引号），在“管理关键字”向导中作为关键字的一部分输入的双引号始终会转义，即使在 C# 风格的项目中也是如此。
