  1. Data Annotation Services and Its Various Types

  2. What is Data Annotation in Machine Learning? Data annotation is the process of adding metadata to a dataset. This metadata usually takes the form of tags, which can be added to any type of data, including text, images, and video. Adding comprehensive and consistent tags is a key part of developing a training dataset for machine learning. Data annotation is an indispensable stage of data preprocessing because supervised machine learning models learn to recognize recurring patterns in annotated data.

  3. Data Annotation Types • Semantic Annotation: Semantic annotation is the task of annotating various concepts within text, such as people, objects, or company names. Machine learning models use semantic annotated data to learn how to categorize new concepts in new texts. This can help to improve search relevance and train chatbots.

  4. Image and Video Annotation: Image annotation comes in a variety of forms, from bounding boxes, which are imaginary boxes drawn on images, to semantic segmentation, where every pixel in an image is assigned a meaning. Video annotation often involves adding bounding boxes, polygons, or key points to content. This can be done on a frame-by-frame basis, with these frames then stitched together to help track the movement of the annotated object, or in the video itself using a video annotation tool.

  5. Text Categorization: Text categorization and content categorization refer to the task of assigning predefined categories to documents. For example, you can tag sentences or paragraphs within a document by topic, or organize news articles by subject such as domestic, international, sports, or entertainment.
