Outsourcing Data Annotation: Challenges & Solutions

Despite its lack of glamour, data annotation is quietly emerging as one of the key areas of competition in a world where AI technology and its rapid development have become increasingly competitive. Individuals and large organizations alike face significant challenges due to outsourcing obligations in a world where backup responsibilities increasingly burden data annotation. The issues encompass privacy preservation, annotator training and management, technological difficulties, and cost-effectiveness, among others.

It all comes about as a combination of the requirement to follow regulations, scaling needs, and the nature of various types of data. If left unmitigated, these challenges can have significant downstream impacts, such as misallocation of resources (inefficiency), risk to compliance and fiduciary oversight, and constraints on model performance. Therefore, companies need to understand and overcome the challenges of outsourcing data tagging so that they can better access the full capabilities of artificial intelligence.

Data Annotation: Consistency and Outsourcing

Of course, data quality is the top priority when it comes to outsourcing your data annotation tasks. Noise, irregular labeling, and low quality are visible obstacles to the smooth functioning of ML models. Even minor errors, amplified during model training, can result in inaccurate predictions.

Data integrity gets progressively harder to maintain as data collections grow in both volume and complexity. This may introduce quality issues, such as annotator fatigue or weak and inconsistent supervision for tasks more complex than those involving simple classification. Another difficulty in maintaining consistency is the need to correct mistakes at a domain-specific level.

Risks of Privacy and Security on Data

Outsourcing data annotation primarily involves sending sensitive information to third-party vendors, raising legitimate concerns about data privacy and security breaches. Dealing with such massive amounts of data undoubtedly raises privacy concerns on both the acquisition and process fronts. Whether it’s image and video data from sensors or files containing personal identification information, it’s possible to compromise sensitive data. Consequently, it has become an urgent matter to implement comprehensive privacy policies and compliance measures to guarantee the correct utilization of data. Regulatory bodies have mitigated the potential for legal disputes arising from privacy violations by issuing numerous data protection regulations.

Potential Comprehension Gaps with Annotators

The interpretive dissonance for a particular project may be the result of the annotators’ lack of domain expertise or unfamiliarity with the project’s context, which results in inconsistencies that compromise the quality of the annotation.

Neglecting Essential Annotation Features

The tools and technologies your project depends on are crucial in the rapidly changing field of data annotation.

However, the sheer variety of available annotation tools can be overwhelming. Choosing the wrong/misfit tool here would eventually result in inefficiencies/suboptimal quality annotations and the models trained on this data. Similarly, there is an increasing need for sophisticated tooling as annotation projects grow in complexity with multimodal data sources or intricate label taxonomies and advanced methodologies such as 3D annotations.

The Outsourcing Process: Time and Efficiency Drains

In numerous data processing and machine learning projects, manual data annotation is a fundamental yet critical phase that occupies the centre stage. Nevertheless, the process of manually annotating data is both error-prone and labor-intensive.

The potential impact of annotation efficiency extends throughout the entire project manager lifecycle. Far from being a mere inconvenience, delays can bust budgets and delay timelines for your projects—leading to the loss of hard-won competitive advantage. A lack of communication can lead to the desynchronization of both internal and external workflow, complicating timely resource allocation. Working without visibility during the creation of annotations poses a risk, as the cost of correcting errors or delays could arise later in the project.

Cost Uncertainty in Data Annotation Outsourcing

Organizations that are contemplating outsourcing data annotation services continue to prioritize pricing. In their pursuit of cost-effectiveness, numerous organizations frequently disregard concealed expenses, including quality control overhead, project management, and vendor vetting. These costs can inadvertently undermine the intended cost savings of outsourcing. For instance, machine learning projects may fail due to poor-quality outputs in annotated data, resulting in rework and rectification costs that exceed the initial savings from outsourcing. Therefore, companies must exercise extreme caution when comparing potential long-term prices to the original costs, as pricing is a complex and nuanced topic.

Velan Solves Outsourcing Challenges

How does Velan ensure its data quality remains at the forefront of industry standards?

All components in the quality assurance mechanism of Velan, such as real-time error detection, multiple validation stages, and customizable criteria, ensure that annotation results are accurate with a very high prevalence. You can also change the mechanisms’ regulations before annotation starts. The system immediately detects errors in labels, enabling prompt repair; you can go back and fix or top up labels as needed. The system’s design aims to maintain composure and offer a reliable data foundation for your computer vision projects.

What are the sophisticated data privacy and security measures that Velan has implemented to safeguard your project?

We prioritize the protection of your valuable information by implementing robust data protection protocols and maintaining industry-leading security certifications such as ISO 9001, ISO 27001, GDPR, and HIPAA compliance. Our multilayered approach guarantees the protection of your data by integrating physical security, cybersecurity, and advanced internet technology. We enable your projects to prosper with complete peace of mind and unwavering trust in our secure services by leveraging stringent measures and expertise in data privacy, thereby empowering you to focus on your core business objectives. We also offer a private on-premises deployment of our annotation software so that you can keep your data in-house but still run the same number of labeling tools at scale, providing full control and ownership over everything within your secure infrastructure.

How does Velan ensure a communicative and skilled workforce of annotation professionals?

Our primary objective is to guarantee that annotators have a comprehensive understanding of the project’s requirements and objectives. We ensure the expertise of our personnel by conducting a rigorous vetting process that guarantees the recruitment of only annotators with professional backgrounds and domain-specific knowledge. Each project has a dedicated manager who works to create consensus across the entire team, answer questions in real-time, and interact with clients directly on quality checks. We do our best to refine these processes over time for individual client needs by creating a feedback loop that helps us balance things accordingly.
