Top Human Annotation Services for AI Projects

Human Annotation in Machine Learning

Before AI-powered tools can identify objects or understand speech, they need people to teach them. The human-in-the-loop model assumes that machines improve their performance using data processed by humans. Only with people’s help can AI deliver relevant search results, recognize faces, recommend products, identify diagnoses, etc.

Machine learning (ML) models become effective only when they learn from quality training datasets. Creating these datasets is called data annotation, which assumes that professionals mark texts, images, audio, or video files with specific tags. Though every data annotator uses advanced software for marking files, this process is also called manual annotation. 

We have extensive expertise in assembling small and large data labeling teams. Our professionals work equally effectively when marking lines and identifying specific areas on, for instance, medical or agricultural images. The teammates we find for you will train AI algorithms to understand human speech and texts. So our data annotation services will help your software perform with high accuracy.

Your Benefits of Hiring Our Human Annotator

Here are several reasons why cooperation with us is beneficial for you: 

goal

You save on remuneration

Building remote annotation teams with us cuts your payroll expenses up to 15% — compared to data labelers hired in the USA and Western Europe. This appears due to the lower cost of living in Ukraine.

analytic

You minimize office expenses

Employing an entire team would mean arranging working space for them. In your country, office rentals can be substantial, while premises cost in Ukraine can be significantly lower.

calendar

Your team will start working after several weeks

Since our recruiters apply proven techniques, use advanced tools, and leverage vast professional networks, they assemble teams quickly. Moreover, we have talent pools of qualified data labelers.

You'll leverage advanced data labeling and annotation tools

We are responsible for the quality of the AI data annotation services our teams deliver. That's why we equip them with top-notch annotation tools.

cv

You don't have to search for candidates

When you confirm cooperation, our recruiters do the most challenging work for you. They embrace announcing vacancies, processing resumes, interviewing candidates, and onboarding team members.

Human Labeling Services We Provide

No matter what kind of data annotation services for machine learning you need, we can help:

Text Annotation

computer

If your AI-powered solution uses NLP (Natural Language Processing) models, be sure your chatbots, translators, voice assistants, and similar tools will learn from the best datasets. We also offer the Optical Character Recognition or OCR text annotation service, embracing the two main areas of text data annotation.

Image annotation

programming

Classification of separate or all objects on images is the basis for computer vision. Image annotation services have become trendy because businesses need to ensure the privacy and security of data. However, computer vision annotation helps agriculture, manufacturing, and healthcare companies save thousands of dollars. 

 

Data classification

server

Our specialists can help you identify irrelevant or duplicated files in your datasets or detect critical information in your database. This way, all your documents will be labeled and organized, allowing you to find required information urgently. 

Video Annotation

content

Labeling videos involves more work than tagging images. For instance, a half-minute video with 24 frames per second requires processing hundreds of frames. But customers trust the video annotation services we deliver because our teams use professional tools and have years of relevant experience. 

 

Audio transcription

music

 With powerful instruments for audio annotation and collaboration under the belt, our annotators will transcribe your audio files quickly. Like all top-rated audio annotation companies, we support all popular languages and guarantee the confidentiality of your data.

Industries We Serve

The annotation projects our data labelers serve are diverse. And below are examples of which industries we work with:

Healthcare

AI-driven medical solutions help doctors identify diagnoses quickly and accurately. The same way our annotators label your radiology, CT, or other images: they're fast and careful at work.

industry icon 1

Insurance

We teach your algorithms to identify various car damages and automate making decisions. Our labelers typically use bounding boxes and 3D cuboids to place relevant tags.

industry icon 5

Finance

In addition to human-like chatbots, some banks also use face recognition technologies. AI helps them verify the identities of people who withdraw money from ATMs.

industry icon 7

Government

Terabytes of governmental data need classification and structuring. And artificial intelligence copes with the task much faster than humans. We value the trust to our data annotators and always prioritize the data privacy and security of every client.

industry icon 9

Agriculture

Knowing when it's time for fertilizing and harvesting, monitoring plants’ health, and deciding on using pesticides are critical for agricultural companies. And professional image annotation helps them save thousands of dollars.

industry icon 3

Security

Computer vision empowers security cameras with the ability to identify potential threats. This way, AI algorithms can warn security personnel and help them prevent violence or similar problems.

industry icon 8

Retail and e-commerce

Online shops use tagged images of clothes and other products to help buyers find their goods. Accurately marked pictures are part of their marketing efforts.

industry icon 6

Legal

ML projects that help identify text on images support lawyers during preparation for courts. Machines process megabytes of pdf files for people, freeing them for human-needed tasks.

industry icon 4

Self Driving

Annotation teams stand behind such trendy projects as autonomous vehicles. That's how the accuracy of labels on pictures and videos directly impacts the safety of people.

Human Annotation Types and Techniques We Use

These are the text, audio, image, and video annotation types that our specialists can do for you:

Bounding Boxes

Data annotators limit objects with 2D boxes. This approach is used, for instance, to categorize stock images, check shelf inventory levels, assess the damage to a car, map the environment, etc.

ai icon 8

Polygonal Segmentation

Data annotators use polygons when customers need to identify non-cuboid objects on aerial images. Specialists place dots on object peak points and then connect them with lines.

Entity Annotation

When it's necessary to mark proper names or keywords, we use entity annotation. And to give users additional information about the word or phrase, text annotators use entity labeling. This means they add links to external databases.

settings

Semantic Segmentation

Tagging every object or area of an image with predefined labels is widely used for autonomous driving. Moreover, this technique allows AI-driven medical software to analyze CT scans and X-ray images.

ai icon 5

Lines and Splines

This technique identifies road markings and traffic signs that help self-driving cars avoid accidents. Also, it allows warehouse robots to move and place items safely.

ai icon 7

3D Cuboids

This annotation type's use cases are similar to bounding boxes except for adding depth to objects. Once the object edges are hidden behind other objects, labelers approximate them and teach AI to do the same.

ai icon 2

Landmark and Key-Point Annotation

This method is also called pose estimation or dot annotation. Labelers use dots and lines to create the skeleton of a person or part of a body. Placing a sequence of key points on face images empowers face recognition algorithms.

ai icon 4

Linguistic Annotation

You'll use our linguistic annotation services to separate intonations, pauses, parts of speech, or other grammar elements. This approach is similar to entity annotation but considers different elements in a text.

ai icon 9

Content and Text Categorization

With this method, you can classify entire paragraphs or texts. For example, this technique can help lawyers categorize hundreds of documents and save hours.
