Data Annotation Services

We make AI/ML viable with explicit data, relevant contexts, and meticulous domain-specific semantics.

Data Support for Artificial Intelligence and Machine Learning

AI and ML dictate a new approach to business – one that requires a secure and constant flow of data to learn, grow and create value. You simply can’t handle a computer tons of data and expect it to learn – data needs to undergo some preparation in order for the computer/machine to find patterns and inferences within it. Thus, for machine learning models to learn efficaciously and systematically, there is a dire need for the right mix of expertise, time, resources and understanding – which might prove challenging for some organizations. That’s why it makes complete sense to outsource data annotation services and bring in third-party experts who can escalate the quality of your AI algorithm’s predictions.

The best part: once you hire data annotation service providers or data annotation companies, you can spare ample of time and resources to focus on other critical tasks of your business.

What is the need to annotate data?

Annotating data is essential in creating datasets used to train machines. Using the datasets, professionals can make machines learn and understand visuals and textual information efficiently. With annotation, you can create a clear and in-depth image of an object in front of a machine. Doing this will help the machines in understanding what the object is and how it is different from others. Besides this, annotating data also makes reading more impactful as it helps in remembering the information about a particular object or an element.

How can you annotate data efficiently?

If you want to annotate your data efficiently, you need to act smartly. You can do this by highlighting only the important part of the data. While annotating efficiently, you also need to ensure that you highlight text about the object that you are targeting. While annotating, text can vary from one word to one or two lines depending upon the explanation required.

Is it necessary that your annotators must be subject matter experts?

Whether you need annotators that are subject matter experts depends upon the complexity of the annotating data. It is better if a qualified professional handles the data annotations. Most data annotation service providers do not use experts with specialized skills to annotate the data, but we are not the same. We at SunTec Data have in-house data annotators that are subject matter experts and are a perfect fit to annotate your complex data efficiently without any errors. We understand that the datasets are of no use if they are not accurate. Incorrect data sets can lead to improper training of the machines, so always choose professionals for data annotation.

Is there any difference between Data Annotation and Data Labeling?

Data annotation and data labeling are different from each other. Both of them are interchangeably used to create datasets to train machines as part of the AI model. Both data annotation and data labeling use different content tagging types and styles. Data annotation labels the objects to create datasets that make machines easily understand and recognize better. On the other hand, data labeling adds more info/metadata to various data types like text, audio, image, and video.

Should I outsource data annotation work or perform it in-house?

It is better to outsource data annotation work to renowned third-party service providers. If you annotate data in-house, it will be expensive compared to outsourcing. Also, annotating data requires time and effort that will impact your efficiency at work and hinder focus on core business activities. Therefore, it will be wise to outsource the data labeling services to the market leaders like SunTec Data. We will ensure that your data is annotated by professionals who have expertise in the domain. Also, you will get 100% accurate datasets by opting for our services.

Is it safe to outsource my data annotation work to the vendors?

Yes, it is safe to outsource data annotation services to professionals and renowned vendors. Several data annotation service providers like us annotate data following the standards and guidelines to maintain safety and accuracy. Also, professional service providers like us have in-house experts that have signed NDAs with the company to add extra security to the process.
