It is a lesser-known fact that much of Artificial Intelligence (AI) is powered by humans. Machine learning (ML) algorithms that are gaining much attention worldwide depend on humans that provide detailed labeling to the data to train the learning algorithm in a supervised environment. As machines cannot interpret data, humans are responsible for bringing machines up to speed. So, human dependency is the unspoken vulnerability of AI.

What are Data Annotation Services?

Data annotation involves labeling data in texts, images, audio, or video, to give additional information and provide context to make them easier to analyze and categorize. This enables machines to understand the said data clearly, improving the performance of AI and machine learning models.

Types of Data Annotation Services

Listed below are some of the data annotation services provided by companies:

Video Annotation

Video annotation services help clients to annotate videos by remodeling each video into a collection of frames and converting it back as soon as the annotations are completed. It provides a stable object-tracking system for the machines. Good annotators decide the accuracy of object recognition in a particular video.

Text Annotation

Text Annotation Services help process large volumes of data. Skilled annotators can provide you with specific classifications and keyword tags, name recognition, sentiment analysis, categorization of texts, and much more.

Speech Recognition and Audio Transcription

Data annotation helps businesses with more accurate speech recognition. Businesses that require digital speech recognition can hire annotation services for audio interpretation and control functions. The annotations can also help with audio transcription, where the transcribed text formats are machine-readable.

Industry Usage

Data annotation is a popular tool used in various industries today. Industries like finance, insurance, automated vehicles, commerce, agriculture, social media, law, and government use data annotations.

Image Annotation

Annotation experts provide high-quality image annotation services, which boosts machine learning. The services may include annotating 2D bounding boxes, polygon, semantic segmentation and annotation, LiDar, and image classification. Data annotation services process images so machines can analyze and identify images like humans.

Machine Learning models these days are required to be more domain-specific. Therefore, the data annotation task gets more complicated and tedious. For instance, in the healthcare sector, businesses are preparing high-end innovations that can diagnose multiple areas of concern. To create these technologies, first-hand ML training is required for algorithms and images to identify the problems.

How Does AI Work?

What powers modern AI is the system of machine learning. The seven patterns of AI, namely, computer vision, predictive analytics, pattern and anomaly detection, autonomous systems, hyper-personalization over a series of applications, goal-driven systems, and natural language processing, are what organizations tend to implement more. However, these algorithms should be trained to interpret data to forecast accurate predictions. The deep learning neural network, an advancement in machine learning, needs large volumes of data to create highly accurate models. The data used for analysis should be clear, complete, and, most importantly, well-labeled. Only then the resultant ML model can deliver accurate predictions.

When it comes to human intervention, resources should be trained. So, businesses invest time to ensure accurate labels on specific data to supervise ML and achieve learning goals. Customers possess data, but they should be equipped to analyze and label large data sets. Finding a skilled task force is challenging, and leveraging an external support team often leads to inaccurate results. Outsourcing bridges this gap, as service providers are equipped to manage large-scale data labeling swiftly and accurately.

Why are Human-powered Data Annotation Services Necessary?

Data Annotation with a human touch is crucial to train the ML algorithms efficiently and improve their accuracy. Humans easily understand and interpret complex content. This is a necessary feature for AI as they use object detection, speech recognition, and sentiment analysis. Moreover, well-trained human annotators can correctly identify whether the machine-generated annotations are of good quality by providing well-labeled data. When it comes to images and videos, humans can provide additional information about the graphics that machines cannot, such as facial expressions and attributes of objects. Hence, human-powered data annotation services are necessary to improve the quality and performance of Machine Learning Models and AI.

Conclusion

The machine learns from the processed content, which is accurately tagged via human inputs. That data is retained for automated processing of the pre-existing data to deliver results. Machines require context to analyze information and judge, just like humans do. Thanks to data annotation, which accurately categorizes information to train the AI to provide definitive conclusions, machines are, thus, able to analyze information and produce outcomes. In the foreseeable future, the requirement for human-powered data labeling will remain the same but grow into newer domains that need further knowledge. This will, in turn, require data annotation professionals that are the real reason behind the success of AI.
