Data annotation is expected to play a major role in enhancing the applications of AI in the healthcare sector. AI-backed machines use machine vision or computer vision in medical imaging data technologies to sense patterns and identify possible injuries, which assists medical practitioners in automatically generating reports after the individual is examined. The database of CT scan, MRI, and X-Ray images can be easily screened by the AI to determine various injuries. Data annotation tools help train AI systems in differentiating data obtained from normal and injured medical images to generate the final reports of the examined individuals. Thus, data annotation tools are expected to play a major role in enhancing the applications of AI in the healthcare sector.

For instance, in June 2018, Innodata Inc., a U.S.-based company that offers consulting and business process technology services has announced the launch of managed data annotation and labeling services for its customers in industries including healthcare, financial services, legal, and pharma. The company aims to provide advanced data annotation tools to its clients along with attributes such as high-quality and accurate data annotated, user-friendly, and quick processing time. Further, the solution comprises features such as labeling content for search, building intents, and utterances for conversational agents, mapping data for ontologies, document classification, recommendation engines, and customer insights.

Technologies such as the Internet of Things (IoT), Machine Learning (ML), robotics, advanced predictive analytics, and Artificial Intelligence (AI) generate massive data. With changing technologies, data efficiency proves to be essential for creating new business innovations, infrastructure, and new economics. These factors have significantly contributed to the growth of the market. Owing to the rising scope of growth in data labeling, companies developing AI-enabled healthcare applications are collaborating with data annotation companies providing the required data sets that can assist them in enhancing their machine learning and deep learning capabilities. For instance, in November 2020, Telus International, a provider of digital customer experience (CX), and digital IT solutions and services announced to acquire Lionbridge AI, which offers training data and annotation platform solutions used for designing AI algorithms to power machine learning.

However, the inaccuracy of data annotation tools acts as a restraint to the growth of the market. For instance, a given image may have low resolution and can include multiple objects that make it difficult to label. The primary challenge faced by the market is issues related to inaccuracy in the quality of data labeled. In some cases, the data labeled manually may contain erroneous labeling and the time to detect such erroneous labels may vary, which further adds to the cost of the entire annotation process. However, with the development of sophisticated algorithms, the accuracy of automated data annotation tools is improving and thus reducing the dependency on manual annotation and the cost of the tools in the near future.
