The word “algorithm” is ubiquitous today. It is as prevalent as the term Artificial Intelligence (AI). In fact, AI and algorithms are inseparable. Broadly, algorithms instruct a computer on transforming data into insights that inform decision-making. Specifically, it has become fundamental to AI-powered solutions.
With the abundance of data and the diversity of its sources, it has become critical to building Machine-Learning (ML) models that resolve high-dimensional challenges. ML, an AI application, uses algorithms to enable machines to learn continuously from decision-making examples or training data and improve. Consequently, what Gartner believed back in 2016 “that the predominance of algorithms will only increase in the digital age”¹ has come true.
Today, algorithms are helping to distinguish diseases at the molecular level².. They are being developed to mitigate disruptions when critical networks such as power distribution, air traffic control, etc., are under targeted attacks³. Besides, algorithms are playing an intrinsic role in our day-to-day lives. For example, from shopping online to over-the-top platforms and from Alexa to your social media channels, leverage algorithms to provide what you want or like at your fingertips.
The hard fact is that algorithms would only be able to perform with annotated or labeled data. In other words, data annotation or labeling enables algorithms to do the tasks they are designed to do.
The process of labeling data sets to make them machine-readable is data annotation. Data annotation or labeling is regarded as an indispensable adjutant to machine learning. They help develop and enhance the capability of machines to identify patterns from previous experience or data.
Consequently, if data is incorrectly annotated, the algorithms will deliver results that do not meet the business objective for which they were generated. The algorithms will learn the wrong lessons from the incorrectly annotated data, execute wrong calculations, and deliver misleading results. For specific and complex business objectives, Straive believes it is advisable to engage subject matter experts to ensure the quality and relevance of the annotated data.
Furthermore, industries like financial, information services, banking and insurance, life sciences and healthcare, real estate, and legal have complex data sets that require the services of these subject matter experts to ensure the labeling does not go off the rails.
Data is humungous in volume and available in numerous formats and types. As a result, there are many data annotation methods. Let us tell you more about data annotation types and their uses.
Text annotations - Today, the challenges of analyzing text data and the mounting realization of its strategic importance drive the need for text annotation. Text annotation allows enterprises to get the full value out of all their text-based data sources by making the important keywords in the texts understandable to machine-learning algorithms.
Text annotation is the process of adding tags or labels to text data to determine its meaning better. Cognitive text data annotations allow enterprises to harness the text's potential information and help machines interpret human language. Natural language and linguistics are leveraged to provide text annotation.
Image annotations – Image annotation or tagging is the first step in making datasets useful for machine learning in image recognition. In computer vision, it performs the vital function of enabling computers to view and interpret visual information from digital images and videos.
Moreover, image annotation helps to assign captions, identifiers, and keywords to images as attributes to help train the ML models. Frequently bounding boxes or semantic segmentation is employed to facilitate a range of AI-based apps such as facial recognition, computer vision, robotic vision, and autonomous vehicles, among others.
Video annotations - Video annotation is the process of labeling or annotating objects in a video clip on a frame-by-frame basis to enable machine learning models to detect or identify objects. It prepares datasets for optimal machine learning functionality. Video annotation calls for a combination of skill and technology, as it is essential for building a comprehensively labeled dataset optimized for a business objective.
Video annotation types and techniques are similar to image annotation, like Bounding boxes, 3D cuboids, semantic segmentation, polygon annotation, etc. In addition, there are key-point annotations, frames classification, and video transcriptions. Processes such as object location and tracking performed by computer vision models require video annotation data, along with a coherent performance of concepts like location, motion blur, object tracking, and more.
Audio annotations – Audio annotation labels audio recordings to develop, train, and improve conversational Artificial Intelligence (AI), chatbots, and speech-recognition AI engines. This technique requires the services of qualified linguists from across the globe. Labeling and transcribing audio files parts to extract meaningful insights from audio formats is also a part of the audio annotation.
Many dynamic concepts in an audio file, such as language, speaker demographics, dialects, mood, intention, emotion, and behavior, make audio annotation a complex task. It requires understanding and identification of all these parameters as they need to be labeled using methods like music tagging, timestamping, acoustic scene classification, and more. Let’s remember the nonverbal cues consisting of sighs, silences, or for that matter, even background noises can be annotated for the machines to achieve a usable understanding of the audio files.

Enterprises tend to employ data from external sources in their data strategy to convert insights into financial gain as they mature in their data journey. This external data comes in diverse forms. However, for enterprises, the most critical is public data.
There are currently no compliance mandate around ESG reporting, especially for private companies, and such reporting is voluntary. While many large companies report on ESG as part of CSR, growing awareness among investors and consumers about ESG has led to this becoming a more widespread practice.
