Managing Data Labels

Create labeling session

In the Data Labeling page, select Choose from OOB labeling template.
In the Configure data labeling page, select the out-of-the-box package you want to configure. For the purpose of this example, we will use Email. The Email template is a combination of text classification and entity recognition labels.
Enter a name for the Data Labeling section and choose the Dataset. You can also create a new dataset from this page. For more information on datasets, see the About Datasets page.
Click Create.

Configure

In the Configure tab, you can configure the labels needed for your session.

There are two ways in which you can configure the labels:

Using a General UI
Using the Advanced editor

The left panel is the label config editor, while the right panel shows a preview of the current config. The right panel also shows the text components that are a part of the template. In this example, the Email template comes preset with a From, To, CC, Date and Text fields. You can add/remove these text components using the Advanced Editor.

Note: The text components configured here determines the structure of the files imported for labeling.

Using the interface

You can add new labels by using the interface from the General tab.

To add a label, click on ➕ next to Entity Label. Add the following information for the new label:

Name: the name of the new label.
Input to be labelled: choose which text component you want to be labeled. In the case of Email AI, you chose between Date, From, To, cc, and text.
Attribute name: choose label names for the entities in your data. Use this to create attributes such as customer name, city name, telephone number, and so on.
Shortcut: choose a hotkey for the label. Use this to configure a key as a shortcut. Only single letters or digits are supported.
Color: choose a color for the label to distinguish it from the others.

Note: You can add more attributes for the same label by clicking on + Add new.

To add a classification, click on ➕ next to Classification. Add the following information for the new label:

Name: the name of the new classification.
Classification Type: choose the type of classification. You can choose between Single and Multiple.
Attribute name: choose label names for each class or value in your data. Use this to create attributes such as sentiment (positive or negative), the type of email (customer, marketing, spam), and so on.
Shortcut: choose a hotkey for the attribute. Use this to configure a key as a shortcut. Only single letters or digits are supported.

Note: You can add more attributes for the same classification by clicking on + Add new.

Using the Advanced Editor

You can add new labels by using the Advanced Editor tab.

To add a new label, make sure to use the following format:

<Label value="NewLabel"
                        background="color"/>

. Add the labels in the <Labels name> section. Once you add the new label, it will be displayed on the right side of the screen.

Once you finish adding all the needed labels, click Done.

Note: Once configured, you can also reconfigure the labels by clicking Reconfigure.

Note that if you want to reconfigure data labeling, all labeled data that has not been exported will be lost and needs to be sent to labelers again.

Import

In the Import tab you can import the needed files for labeling. The labeling tool supports files in the JSON format. The JSON file should contain a data object that in turn contains the structure configured in the previous step. Here's a sample JSON file structured for the default Email template, containing From, To, CC, Date and Text fields as name-value pairs within a 'data' object.

{
  "data": {
    "date": "1/29/2021 12:29:01 PM",
    "from": "[email protected]",
    "to": "[email protected]",
    "cc": "",
    "text": "I currently have 4 separate student loans that I have been paying on for years with Citi,..."
  }
}{
  "data": {
    "date": "1/29/2021 12:29:01 PM",
    "from": "[email protected]",
    "to": "[email protected]",
    "cc": "",
    "text": "I currently have 4 separate student loans that I have been paying on for years with Citi,..."
  }
}

Once added, click Upload.

You can check all your uploaded files in the Uploading and Validating Files window. If there is an error to any of the files, the error message will help you in editing the file in order to meet the requirements.

For example, the cc field is missing in one of the uploaded files.

Once you checked the uploaded and validated files, click Done.

Labels

Note:

If you are using Chinese or Japanese, granularity="word" must be removed using the Advanced Editor.
If you are using right-to-left languages, you can set view style using the Advanced Editor. To change the alignment, add view style="text-align:right" in the Advanced Editor.

AI Center
