Smart Labeling

Machine learning assistance to accelerate ROI on your AI initiatives

Smart Labeling features a suite of innovative capabilities using Machine Learning in the data annotation process to improve productivity, quality, and delivery of your data collection and data annotation projects. This produces better model outcomes – giving you high-quality training data and accelerating the ROI on your AI initiatives. 

Our Superpixel tool allows fast annotation of pixel groups ("superpixels") that correspond to an object's boundary.

Appen Smart Labeling Focuses
on Three Specific Areas

Machine Learning can drive quality and time saving in the data annotation process:


Machine Learning provides an initial 'best estimate’ hypothesis before contributors start the task allowing them to save time and make minor adjustments only if needed.

Speed Labeling

Machine Learning provides for in-tool efficiency, quality and accuracy improving labelling productivity.

Smart Validators

Machine Learning models verify human judgments against model predictions, reducing the requirement for manual QA.

Trusted by global leaders to power their mission-critical AI with data for over 25 years

Smart Labeling Capabilities
our Customers Enjoy

Pixel masks are automatically generated and applied to an image for contributor validation saving time and effort.

Pre-Labeling for Autonomous Vehicle Image Pixel Labeling

Images are automatically applied with Pixel Labeled classes based on the ontologies you choose and then verified by a contributor. A/B tests show 91.5% productivity improvement without quality compromise.

Speed labeling eliminates the need to annotate every single frame and expedites the annotation process.

Video Annotation with Speed Labeling

Contributors label each object in the first frame, then Speed Labeling tracks and predicts object locations in subsequent frames where contributors supervise and correct as needed. This results in up to 100x faster annotation speeds.

Speed labeling cuts judgment time by 33% and supports 31 languages.

Image Transcription with Speed Labeling

Contributors box text in an image and then OCR assistance predicts transcribed text. Speed Labeling increases efficiency up to 33%.
Check for language, duplicates and coherence to make sure only high quality utterances are captured.

Text Utterance Collection with Smart Validators

Utterances are checked against three validators (duplicate detection, coherence detection and language detection), delivering a 35% reduction in error rates.

Secure Data Access

Data security requirements are met for customers working with personally identifiable information (PII), protected health information (PHI), and other sophisticated compliance needs.

Enterprise-level security to protect sensitive client data

Secure Crowd

We offer a suite of secure service offerings with flexible options to ensure data security via secure facilities, secure remote workers, and onsite services to meet specific business­ needs.

Enterprise-level security to protect sensitive client data

Secure Facilities

We have sites in multiple geographies to support projects with Personally Identifiable Information (PII) and other sensitive data, as well as the right people, policies, and processes in place for a range of security levels, up to government level certification.

Enterprise-level security to protect sensitive client data

Secure Workspace

With our ISO 27001 accredited remote Secure Workspace solution, our global crowd can work on your sensitive projects remotely, without having to access a physical secure facility. This allows the diversity of our remote crowd to reduce bias and support multiple languages even through global disruptions.
