5/19/2023 0 Comments Data annotate![]() Sentiment Analysis – You would use this type of annotation to help the machine understand whether the tone of voice is positive or negative.Transcription – If during an audio recording needs to be written down, this s the form of annotation that will be used.Optical Character Recognition – This is when you need the system to recognize the characters printed or handwritten on the page and transform them into editable text formats.Timestamps – This is when certain events happen in the video or audio and you need to place a timestamp when this event happened.Landmark Annotation – This form of annotation is used to place key points along peoples’ facial features so the system can recognize them.3D Bounding Boxes – If you need to annotate the dimensions of the object such as length width and height, 3D Bounding Boxes would be used.2D Bounding Box – This is simply drawing a square or a rectangle around an object in an image.Lines and Splines – This is where all of the boundaries of the objects are contoured.Semantic Segmentation – One of the most detailed types of annotation where you classify each pixel in an image.Tagging – This is simply labeling all of the people or objects.There are also many types of data annotations. LiDAR – Annotating the 3D Point Cloud produced by the LiDAR.Audio annotation – Annotating sound and speech.Text annotation – Annotating written text, both types and handwritten.Video annotation – Annotating moving images.Image annotation – Annotating still images.There are several classifications of annotations: Let’s start by looking at some of the industries that rely on machine learning and AI and what data annotation is required for such projects. As we will see later on, data annotation is required for AI projects in any industry and it is an essential aspect of any machine learning project. This, in essence, is what data annotation is. This training data needs to be annotated by human workers to prepare the raw data to be consumed by machines. However, in order to create such systems, a lot of training data is required to allow the machines to recognize things we want them to find. AI and machine learning are some of the fastest-growing technologies that offer incredible innovations that benefit various sectors of the global economy.
