Why is Data Annotation Services Important in Machine Learning and AI?
What is Data Annotation?
To clarify, data annotation and data labels are interchangeable to refer to the technique for tagging contents in various formats. It uses the data annotation tool which makes objects of particular interest within text, images or videos easily recognizable by computers using NLP or computer vision.
Data annotation is a crucial part of AI/ML projects being scalable. To train an ML model, the model must be able to recognize and identify all objects in algorithm inputs. Different data labelling techniques can be used depending on the project requirements. To make it easier for machines and humans to classify and identify information, additional effort must be made to label data. ML algorithms won't be able to compute the most important attributes if data labels are not completed.
Text Annotation to NLP
NLP text annotation or speech recognition by computers is used to establish a communication system between people using their local languages and dialects. This is where text annotation is used by virtual assistant devices and AI chatbots in order to respond to questions asked by people in their native language.
Different text annotation types exist but a common feature of these is the metadata that's added to create keywords machines can use to make critical decisions.
Video Annotation for High Quality Visualized Training
Like text annotation, video annotation has the sole purpose of making computers recognize moving objects by using computer vision. Video annotation is all about precision. You can annotate frames by frames and other objects to determine their movements.
Video annotation is useful in creating training data or visual perception models for driverless vehicles.
Image annotation for Recognizable Items
Image annotation has one purpose: To make objects of interest recognizable and detectable by visual perception based on ML models, it is done. An image annotation is where the object is annotated, tagged and associated with different elements. This makes it easier to recognize ranging projects by AI-enabled machine.
Different types of image annotation are used when creating training data sets to AI businesses. Among the most popular methods used in ML are 3D cuboid annotation, bounding boxes, landmark annotation and 3D point annotation.
Annotation For Medical Imaging
Data scientists create healthcare training datasets for ML by annotating medical images. Images taken from Radiology departments such as CT Scan and Ultrasound are annotated with medical images to train ML models to diagnose different diseases accurately.
Radiology experts use appropriate annotation tools for manual Image Annotation of medical conditions. AI machines can then detect them in real life situations.
Data Annotation in: Benefits
It's simple:
- Supervised learning provides ML models with accurate training that allows them to accurately predict and estimate.
- End-users can have amazing experiences using ML automated systems. Digital assistants and chatbots, for example, respond to users' questions according to the speed at which they are asked.
- Google is one of the many web search engines that use ML technology, similar to Google, to improve the accuracy and relevancy of their results based the search history of their end-users.
- The ML speech recognition software has also been a great help. It offers virtual assistance for human speech with NLP.
- Correctly labeling data will ensure success in all ML projects. Even the smallest mistake in preparing data for training ML model can prove disastrous and even fatal.
- Data annotation is key to AI's full potential. AI offers many benefits. With the correct data labelling, we can extract the greatest and most valuable from it.
Data annotation services for ML Use cases
Image Annotation
Adobe Stock for Asset Profile: Adobe Stock is one Adobe's most prominent offerings. This is a curated selection of high quality stock imagery. There are over 200 million assets in the library (including many millions of photos, videos and 3D assets as well as editorial assets). Each asset was made searchable by a model based on accurate training data.
Video Note
HERE Technologies: HERE has a track record of providing accurate, detailed and insightful location data and insights to businesses and corporations. Their ambitious ML project required them to annotate tens, thousands of miles worth of driving roads to obtain ground truth data that could be used to power their sign detection models. The solution to this problem was found in Video Object Tracking technology.
