Data labeling for machine learning is done to prepare the data set that can be used to train the algorithm used to train the model through machine learning. And such data contains the texts, images, audio or videos that are properly labeled to make it comprehensible to machines.

To label the data there are several annotation techniques are used like text annotation, image annotation and video annotation, in which important keywords or object of interest are annotated with added metadata to make it detectable or recognizable to machines through NLP or computer vision.
Data Labeling for NLP or Voice Based Machine Learning Model
Depending on the type of data, the labeling technique is used. In case of data available n text format, NLP annotation and Name Entity Recognition or Relationship Recognition is used to train the voice or language based machine learning models like Chatbot or Virtual assistance.
Data Annotation for Computer Vision Based Machine Learning

While for visual perception based machine learning models that are trained through computer vision technology to make the object of interest recognizable to machines. Actually, objects in the images are annotated through different methods as per the visual perception model algorithms.
How to Label or Annotate the Data for Machine Learning?
To label or annotate the data for machine learning, you need certain tools or software, where you can put your raw data and then label it as per the AI model needs. Apart from that you also need knowledge, experience, time and efforts to label the data correctly.
It not seems easy to label the data yourself, especially if you don’t have any idea of this field. Actually, there are different types of data labeling techniques, and which method is suitable for which machine learning model, only machine learning engineers, in collaboration with data scientist and AI experts can know about such things.
So, doing yourself it’s better to outsource your data labeling needs to professional labelers or data annotation service providers, who will do this job for you at lower cost with better quality. You just need to assign them the raw data, they will label or annotate the same with better accuracy that will make your machine learning not only successful but will also give the right predictions.
