Data Annotation: An Overview & Importance

Data labeling or data annotation is the most fundamental process of the artificial intelligence (AI) and machine learning (ML) industry. With the expansion of the AI and ML industry, the size of the coding, labeling and structuring data industry is also swelling exponentially. According to Grand View Research forecast, the global revenue of data labeling AI industry will reach $3.4 billion in 2028 from just $629.5 million in 2021 with a whopping growth of 27.1% CAGR over the forecast period. The demand for a data rating and labeling contractor and an expert data manual labeling has also increased significantly across the globe, especially for building dedicated teams in remote IT outsourcing hubs.

Data annotation is a process of categorizing and labeling the attributes of data in the form of text, audio, video, images, and other forms of input used in the machine learning (ML) and computer-vision artificial intelligence (AI) application. The main purpose of data labeling and classification, commonly known referred to as data annotation, is to build data-sets for training the computer-vision and machine learning algorithms of software applications to clearly understand the input data so that a suitable automated action can be performed for generating the desirable and accurate outputs.

Different models of using different types of procedures to label data such as automated labeling, human-powered annotation, and others. The use of human-annotated data is more accurate and reliable as compared to automated annotation. Thus, a big data labeling company as well as other companies dealing in AI always prefer to use data entry services for human-annotation of the data.

The Main Reasons to Hire a Team of Data Annotators:

  • Higher level of accuracy in data labeling and categorization as compared to automated data annotation
  • Creation of better user experience by enhancing the emotions and other understanding of the machines
  • Adds more intelligence as compared to the automated software about the objects, environments and other forms of data-sets
  • Improved precision of supervised machine learning models and applications for understanding the input data sets more accurately
  • Adds the essence of natural thought processes in the computer models
