A Detailed Guide on Data Labelling Jobs

In the rapidly progressing AI and Machine Learning landscape, the development and training of new models are gaining momentum. AI and ML systems are trained on data that is labelled and annotated by data labellers. Lately, the data labeller job is gaining prominence, and domain experts are being hired by companies like FlexiBench to annotate specialised datasets for client project requirements.

In this blog, we will discuss what exactly is data labelling and dive deep into the data labelling job, its requirements, challenges, and best practices.

What is Data Labelling?

Data labelling is the process of turning raw data into processed, annotated data sets that can be understood by machines and used for the training of AI models. This is done by identifying and adding suitable labels or tags to the data to specify what the data is about and point out individual elements within the data. This labelled data allows machine learning and AI models to make accurate predictions.

Four main kinds of data labelling include Image labelling, video labelling, text labelling, and audio labelling or annotation. Data labelling is the primary job of Data annotators and labellers and they are known as AI training specialists.

Data Labelling Jobs: What Does a Data Labeller Do?

A data labeller’s primary responsibility is to annotate and label datasets, making them understandable and usable for training AI algorithms. Data labellers meticulously analyse and categorise data, identifying patterns, objects, or features within images, texts, or videos.

Data labellers contribute to the development and training of AI models, enabling machines to recognise and interpret information accurately. Therefore, they are called AI training specialists.

Why Data Labelling is Essential for AI and Machine Learning

Data labelling is essential for AI and ML models because these systems are built from the ground up and are taught to interface with the human world and understand it via data. Raw and unannotated data makes no sense to such systems. What data labelling essentially does is point out, tag, and label individual elements, tones, and other characteristics of the data to make it understandable for the AI and ML systems. 

Huge data sets that have been annotated and labelled allow new models to prepare reference points and organically learn new information through repetition and labelling.

Skills and Qualifications for Data Labelling Jobs

Apart from computer proficiency and being detail-oriented, focused, and meticulous, there is no such minimal requirement for starting as a data labeller. The following are the broad qualifications for a data labelling job:

  1. Basic computer literacy:
    Since labelling and annotations are done on computer systems, basic computer literacy and proficiency with the internet are a necessity. 
  2. Attention to detail:
    Data labelling is often a repetitive task that requires sustained focus and attention to detail. Accurate and consistent labelling is necessary for the best possible development of AI models.
  3. Language and Cultural Knowledge:
    Proficiency with language is essential, as text and audio labelling are a huge part of the job. In addition to that, individual elements of image and video raw data and their settings are also sub-parts of image and video annotation that require fluency in languages.
  4. Familiarity with Labelling Software and Tools:
    While it is not necessary to know about tools at an early stage, experience and knowledge of annotation tools are a huge advantage when working as a data labeller.

How to Find Data Labelling Jobs

If you are in the job market for a data labeller job, there are two primary options available:

  1. Crowdsourcing platforms:
    Crowdsourcing platforms like Appen and Toloka have a workforce on their respective platforms that does data annotations as a collective. These platforms are data solution platforms that source data from individual and unspecialised labellers.

    Working on a crowdsourcing platform requires no prior experience and involves little or no training since the data labelling process for these platforms is fairly straightforward and uncomplicated.

  2. Specialised Platforms:
    Specialised platforms such as FlexiBench offer all the above-mentioned benefits but with an added advantage. With FlexiBench, you can be a specialised data labeller, bring in your previous domain knowledge, and work on specific targeted projects with companies looking for data solutions.

    In addition to this, FlexiBench also provides you with flexible commitment options such as hourly engagements, project-based work, part-time contracts, and, if things work out well, full-time jobs as well.

    FlexiBench combines crowdsourced labelling with your pre-existing expertise to create targeted annotated data sets for different clients as per their project requirements.

The Future of Data Labelling Jobs

The future of the work of a Data Labeller in the AI era is filled with exciting opportunities. As AI advances, new opportunities for specialisation requirements will emerge across various industries. The integration of AI technologies necessitates a shift in skills and a focus on human-AI collaboration.

Individuals working as AI training specialists can position themselves for success in a world where this technology plays an increasingly prominent role.

In A Nutshell

In conclusion, data labellers are playing an extremely crucial role in the AI revolution as they produce the basic building blocks on which new AI systems are developed and trained. Their primary job is to add labels and annotations to make the data understandable for AI models. 

Skills like computer literacy, attention to detail, language proficiency, and familiarity with labelling tools are important for this job. And as far as job opportunities are concerned, crowdsourcing platforms offer opportunities, but specialised platforms like FlexiBench provide additional benefits, allowing labellers to leverage their expertise in other domains to create specialised labelled data sets. 

Data labelling jobs are showing promising prospects as AI advances, requiring specialised skills and integration with other traditional industries. Overall, data labellers contribute to the growth of AI and can position themselves for success in this evolving field.
