Data labeling is assigning tags, labels or annotations to a given dataset. Well-labeled datasets are immensely valuable for researchers trying to develop models and algorithms that accurately represent data from the real world. Data labeling is particularly necessary for supervised machine learning, in which machines must be provided with input and output data to learn how to accurately predict their outputs.
Data labeling can take many forms, depending on the dataset and its purpose. For example, some datasets require human input, while others can be labeled entirely by machines. In addition, several third-party tools and platforms, such as image and text data labeling services, make the process simpler for researchers and developers.
In this article, we will go over some of the most popular data labeling solutions available today and their uses cases and benefits. We’ll explore manual data labeling and why it’s important; automated data labeling; crowd-sourcing; tools for annotating images; online annotation services; annotation languages; and finally AI-assisted labelers that have become increasingly popular in recent years.

Comparison of Solutions
Data labeling solutions are invaluable for machine learning applications, since understanding data is a fundamental prerequisite for implementing any AI-based system.
Various solutions are available on the market today, each with different features and benefits. This article will discuss some of the most popular solutions and compare them to help you decide which is best for your situation.
Ease of Use
When selecting a data labeling solution, one of the most important factors is ease of use. Therefore, the chosen solution should be intuitive and straightforward, allowing users to quickly become comfortable with the interface and start labeling data in no time.
To assess the ease of use, consider how user-friendly the platform is to adopt. For example, look for a solution with built-in features like auto ML algorithms that can be configured to automatically label data, or a graphical user interface (GUI) that makes it effortless for users to manually create labels. In addition, ensure that any API libraries are easy to use and can be set up with minimal technical overhead. Understanding documentation in different languages also helps if you use the software internationally. Last, verifying that customer support is readily available in case problems arise is important.
Cost
Cost is a major factor when selecting the best data labeling solution. The cost of each solution may depend on the use case, size of data, requirements and the type of labeling approach (e.g., manual or automated). Some solutions may be priced on a per-annotation task basis or as a subscription cost.
In general, manual labeling solutions tend to be more costly than automated annotation services since they may require more human intervention—such as hiring workers from an online job search platform or using in-house employees whose wages are accounted for in overhead costs. On the other hand, automated approaches can provide faster results and be less expensive since AI/ML models can handle some of the processing work that would normally require manual input at higher speeds and with lower total investment costs; however, these models may not always be accurate enough for production-level deployment depending on the task at hand.
It is important to evaluate all data labeling solutions thoroughly before investing those funds into one approach—manual or automated—by researching each options’ features, accuracy level, turnaround time and pricing model more closely to meet specific use cases.
Features
When researching data labeling solutions, it is important to know the available features. Popular features include automated workflows with multiple crowd workers, real-time tracking of task outcome, and AI-assisted active learning. Depending on the specific use case, different solutions may offer a wide range of features including:
• Data collection: Most solutions will provide tools to collect your raw data. Some solutions are suitable for diverse needs such as web scraping and/or manual uploading into the platform.
• Workflows: This allows you to set up different tasks and assign them to different crowd workers based on their skill level, maximizing efficiency. It can also enable split testing with your labels so that you can compare and assess results from multiple individuals.
• Labeler management: Many solutions have an interface that enables you to oversee and manage your labelers in one place with features such as rating, bonuses, rewards and blacklisting inappropriate labelers if necessary.
• Real-time tracking: With this feature, you can track progress of tasks at any point in time and review completed tasks before concluding a project. This is useful for monitoring task quality as well as timeliness of completion.
• AI-assisted active learning: Solutions such as Snorkel AI allow you to leverage artificial intelligence by helping you automatically remove noisy labels and providing insights into what causes incorrect labels. This saves labeling time, leading to increased accuracy in model training and a faster timeline for model deployment.
Conclusion
The use of data labeling provides a powerful way to produce reliable and accurate data sets for machine learning and other AI applications. Generally, data labeling aims to quickly and accurately categorize or classify data so that it can be used effectively.
