What is Data Labelling?
It is basically the process of identification of properties in any document, text, image or video; and thereby annotating or labelling them with those specified properties. Any identification or classification of latest news on a social media platform, an article, the actual sentiment of a tweet or post, the caption of an image & its inner meaning, crucial words spoken in an audio recording, the gist of a video, etc. are all examples of data labelling. Therefore, data labelling can be considered as a quintessential aspect of Artificial Intelligence (AI) and Machine Learning (ML) projects. Through one such process, you can create and effortlessly browse through datasets, view documents, images & texts, and thereby apply labels or tags to AI/ML models. In layman’s terms, data labelling lets you easily label datasets with bare minimum configuration steps. You’re allowed to label documents in PDF, TIFF & TIF format, and images in JPG, JPEG & PNG format, apart from text in TXT format. The primary resource in any data labelling project is Datasets. It basically consists of records and their respective labels. It can be a single image, a piece of text or a document.
Smart Data Labelling for Computer Vision & NLP Applications
One such complex & time-intensive process is to enrich a wide variety of data sets & data types, which can be in the form of text, image, audio & video. It can also be languages and sentiments. Such high-end and precise services basically help mid-level enterprises, AI startups, universities, research institutions, agriculture & farm sector, law enforcement agencies and various government departments & agencies. Almost all data labelling services are necessary for object detection & tracking, semantic segmentation, image classification and image-to-text transcription. In the video aspect, such a service is required for frame-by-frame object detection, object tracking, video classification, live video stream monitoring & video moderation. Similarly in the area of text & document, it is required for Named Entity Recognition (NER), data extraction, classification, relationship extraction, as well as semantic segmentation in a 3D environment. A labelling service is basically performed to enhance your machine learning, computer vision or deep learning projects. This is how experienced data labelling specialists in the UK like “Aya Data” create high-quality training data sets for scaling up your AI initiative, along with human powered annotations. It is a step-by-step process, involving data collection, annotation, quality assurance and final delivery.
How Data Labelling Works?
It would be a wise decision to outsource your data lablelling requirements to experts that have fully managed annotation teams to accelerate any AI based projects for powering your machine learning initiative. It is done through various techniques such as bounding boxes, semantic segmentation, 3D Cloud point, text annotation, Polygon annotation, Cuboid, etc. The most common types of data labelling are computer vision, natural language processing (NLP) and audio processing. A set of unlabeled data is labeled by humans, in order to make precise judgments. Here, human labellers tag all the images in a given dataset and also verify the accuracy of the labels. Nowadays, machine learning models are available to label data automatically. This makes it easier for a machine to understand and give results. From a technical point of view, the machine learning model utilizes the human-created or automatic labels to identify the underlying patterns through a process referred to as ‘model training’. This is how predictions are made on new data. The bottom-line is to have a highly accurate data labelling for identifying certain classes of objects and thereafter train your computer vision model, in a desired way.
