iMerit Data Annotation Tools in Use

Going forward with iMerit company review, here is some information on the company's tools and tasks performed. For the majority of annotations, iMerit experts use their own tool, Ango Hub, which makes labeling quicker. Even though they can use client’s individual tools, they prefer their own, and use it for all cases. It is also available by subscription for individual annotation.

Ango Hub is used for image, video, and text annotation, and helps with accomplishing the following tasks:

  • Image and video annotation. The tool has such features as autodetect, optical character recognition, and magnetic lasso.

  • Radiology annotation product suite. Called iMerit Radiology Editor, it supports medical imaging annotation. It works with various formats, has data compliance, and helps to partially automate manual annotation tasks.

  • In-cabin monitoring annotation. The tool helps to create data annotation for a driver monitoring system (DMS). With it, some specific driver behaviors can be auto annotated.

  • Defect detection. The tool includes the application for automated surface inspection. It detects defects in manufacturing thanks to specific built-in algorithms.

  • Crop and weed detection. With built-in ML models, the tool has another application for agriculture and tech industry. It’s beneficial for pre-labeling or auto-labeling for ML-assisted annotations.

  • Ground control. With Ground Control, Ango Hub provides detailed analytics and metrics, and allows keeping the case materials in one place. It makes the annotated data transfer smooth and in a needed format.

  • Edge cases. With the tool, the team of annotators manages such edge cases as reflections of people and objects, hidden signs, and ambiguous objects, among others.

Finally, they have a People platform that contributes to project management, workflow optimization, skill, and talent allocation.

iMerit Integrations

Seamless integration

The company offers no-code integrations. The majority of deployment happens through APIs and plugins. They can integrate various applications and MLOps platforms. The data pipelines can be efficiently integrated even with custom requests.

iMerit Annotation Process

Despite offering machine-assistant labeling for specific cases, the company believes human annotation is faster and more efficient. Moving on with iMerit company review, here are their main steps for data annotation:

  • Consultation with an expert. At this stage, the customer registers with iMerit’s platform and prepares their tech task.

  • Trial and annotators’ training. Depending on the task, annotators proceed with a pilot or proof of concept. During the pilot stage, the group of annotators is chosen and trained, especially if the task requires some specific industry knowledge.

  • Workflow customization. Data annotation happens for the piece of the project, which is defined in the pilot stage.

  • Feedback cycle. The client provides feedback and proceeds to the offer.

  • Evaluation. At the end of every project, the evaluation is done before submission of the final project.

You may be involved in the annotation process at any stage you decide.

iMerit Quality Assurance

During every step of data annotation, iMerit uses various reports, dashboards, and tracking systems to allow efficient project management, identify troubleshooting needs, and track KPI metrics. To ensure the quality of provided annotation, they use a combination of techniques:

  • Setting a gold standard during mini-sets;

  • Using an annotator consensus;

  • Using scientific methods for label consistency;

  • Subsampling.

The solution architect randomly chooses a sample of dataset, around 5-10% of the whole labeled data, and checks for possible errors. AI-based frameworks help annotators to review labeled datasets, which is done a couple of times before the project submission.

iMerit Pricing

Main components of iMerit's pricing

The usage of the iMerit Ango Hub platform requires a monthly subscription. The price range for annotation is universal for all annotation tasks, but differs depending on the dataset volume. It gets flexible based on the annotator's language and location. If there are more than 100k objects to label per month, the company offers discounts.

If you need to export your data in a custom output, you’ll need to pay a one-time charge. To calculate the full price for the project, it’s important to know the scope of annotation and understand how many people will be involved.

iMerit Security and Data Compliance

The standard procedure supposes that for every new client, the company nominates a Security Manager, who plays a role of a mediator between the client and the team of annotators. This person examines the requirements and identifies the security and control measures that should be in place. The manager tracks the processes and the progress, and trains iMerit employees.
