screenId: Unique RICO screen ID
image: RICO screenshot
image_icon: Google Play Store icon for the app
image_semantic: Semantic RICO screenshot; details are abstracted away to main visual UI elements
file_name: Image local filename
file_name_icon: Icon image local filename
file_name_semantic: Screenshot Image as a semantic annotated image local filename
captions: A list of string captions
bbox: The bounding box for the widget being captioned, relatively scaled with the image size so that coordinates are in [0, 1]
app_package_name: Android package name
play_store_name: Google Play Store name
category: Type of category of the app
number_of_downloads: Number of downloads of the app (as a coarse range string)
number_of_ratings: Number of ratings of the app on the Google Play store (as of collection)
average_rating: Average rating of the app on the Google Play Store (as of collection)
semantic_annotations: Reduced view hierarchy, to the semantically-relevant portions of the full view hierarchy. It corresponds to what is visualized in image_semantic and has a lot of details about what's on screen. It is stored as a JSON object string.

Dataset Creation

Curation Rationale

RICO rationale: Create a broad dataset that can be used for UI automation. An explicit goal was to develop automation software that can validate an app's design and assess whether it achieves its stated goal.
Widget Captioning rationale: Create a dataset that helps machines reason about UI elements on screens

Source Data

RICO: Mobile app screenshots, collected on Android devices.
Widget Captioning: Human annotated concise captions for widgets on screen

Data Collection and Processing

RICO: Human and automated collection of Android screens. ~9.8k free apps from the Google Play Store.
Widget Captioning: Takes the subset of screens used in RICO, eliminates screens with missing or inaccurate view hierarchies.

Who are the source data producers?

RICO: 13 human workers (10 from the US, 3 from the Philippines) through UpWork.
Widget Captioning: 5.4k annotators through Amazon Mechanical Turk
