Customize interface

All interfaces (excepted custom interfaces) are divided into two parts:

  • asset viewer on the left
  • jobs viewer on the right

Jobs indicate the implementation of machine learning tasks (such as classification, object detection, etc). Interfaces can chain several jobs in succession. Each job can be either required or optional.

Interfaces can be customized with the interface builder or in JSON settings.

Interface builder

This is a builder to easily customize the interface. It is accessible in the “Settings” tab.

An interface is composed of:

  • Asset type (image, text, video, audio)
  • Machine Learning task (classification, object detection, named entity recognition, etc.)
  • An input (radio button, check box, dropdown, text field)
  • Optional: a tool (bounding box, polygon, line, etc.)

An interface can have: one job

Several jobs

You can add as many jobs as needed for your labeling task.

Or nested jobs

To nest a job, you click on the arrow at the class level. Classification tasks can be nested with single choice up to the 4th level.

Custom render width

Renderer width is a parameter in the JSON file. It has to be between 0 and 1, and is the proportion of the screen given to the annotation tools (the jobs). The rest of the screen is for the asset. Key: jobRendererWidth : (here 0.2, i.e. 20%)

Metadata at asset level

The app allows you to add additional information to the asset, called metadata. Metadata can be uploaded through the API. It can be an image, text, and/or a URL. The code below shows how to attach metadata to an asset with Kili Playground:

metadata = {
    'imageUrl': 'https://myriadrbm.com/wp-content/blogs.dir/20/files/2018/05/cell-3.png',
    'text': 'Normal cell',
    'url': 'https://www.google.com'
}
kili.update_properties_in_assets(
    asset_ids=[asset_id],
      json_metadata=[metadata]
)

You can find more information on the API here or directly in the Github of the project.

Metadata at category level

You can set up metadata at category level. They will be visible by every annotator, directly on the job interface when they hover the information icon at the right of the category:

Category metadata are configured in the interface. You can set them up for every category belonging to any existing job.

  • Go to "Settings"
  • Click on the tab "JSON"
  • Add a jsonMetadata key that can contain text as in the example below:

Custom classes' colors

The color of each class is a parameter in the JSON file. The color code is the color hex code (hexadecimal). To setup a custom class, you can change directly the following key for each category: color: "#941100". You can use an online tool to upload an image and select the perfect color for your task.

JSON settings

The JSON settings fully describe an interface. For 3 successive classification jobs, for instance, it is composed as such:

{
  "jobRendererWidth": 0.25,
  "jobs": {
    "CLASSIFICATION_JOB": {
      "mlTask": "CLASSIFICATION",
      "content": {
        "categories": {
          "ECONOMICS": {
            "name": "economics",
            "color": "#941100",
            "children": []
          },
          "MATHEMATICS": {
            "name": "mathematics",
            "children": []
          },
          "DATA_SCIENCE": {
            "name": "data-science",
            "children": []
          },
          "ANTHROPOLOGY": {
            "name": "anthropology",
            "children": []
          }
        },
        "input": "radio"
      },
      "required": 1,
      "isChild": false,
      "instruction": "What is the topic of this paper ?"
    },
    "NAMED_ENTITIES_RECOGNITION_JOB": {
      "mlTask": "NAMED_ENTITIES_RECOGNITION",
      "content": {
        "categories": {
          "ACTIVE_LEARNING": {
            "name": "active learning",
            "color": "#73FDFF"
          },
          "DATA_TYPE": {
            "name": "data type",
            "color": "#9437FF"
          },
          "MACHINE_LEARNING": {
            "name": "machine learning",
            "color": "#FF9900"
          },
          "AUTHORS": {
            "name": "authors",
            "color": "#FF40FF"
          }
        },
        "input": "radio"
      },
      "required": 1,
      "tools": [null],
      "isChild": false,
      "instruction": "Identify terms specific to"
    }
  }
}

The JSON can be saved, for example, to duplicate a project. It can also be edited interactively.
