What ML Challenges Can In-House Data Labeling and Outsourcing Data Labeling Solve?

High-quality data annotation requires more sophisticated strategies today

What matters in data labeling for machine learning is accuracy, security, and precision. ML projects grow fast when carried out efficiently, and here, the choice arises: in-house vs. outsourcing data annotation.

The majority of data scientists’ work involves working with training data. It has to be properly annotated so that it can be effectively used for a specific use case in machine learning. However, it takes a skilled manpower to perform high-quality data annotation and tackle the following annotation challenges:

  1. Accuracy and consistency: Companies often lack in-house expertise in machine learning and dedicated annotation teams. Assigning annotation tasks to existing personnel, like business executives or industry specialists. However, if they aren’t properly trained, they might not follow the exact instructions, leading to mistakes.

  2. Scalability: Labeling a small batch of data for a new project is feasible. But as projects grow and require more training data, data annotation can quickly become overwhelming. This can overwhelm small and medium-sized businesses, who may struggle to scale their annotation efforts efficiently with limited resources.

  3. Cost and time pressures: As the demand for AI applications intensifies, companies face mounting pressure to deliver solutions swiftly and cost-effectively. Inefficient annotation pipelines lead to project delays, resulting in lost opportunities and additional expenses.

There are two options to overcome these annotation challenges: building a team in-house or outsource data annotation. Let’s delve deeper into each approach.

In-House Annotation Team

The benefits of having an in-house labeling team

In both in-house data labeling and outsourcing data labeling, never disregard data privacy and security underpinning most processes in ML. This means deploying data labeling security strategies to handle massive volumes of sensitive data. Also, some labeled data cannot be transmitted online. And in such cases, having an in-house team makes sense in terms of security and control over your data.

Having your own team of data annotation specialists is great, but it goes hand in hand with tons of human resources to onboard, finances to spend, and time and efforts to devote. Data annotation is deceptively easy, but managing a labeling expert is a commendable effort for the company.

Hiring and training an in-house annotation team is the right thing to do when your ML project is long-term and includes large datasets. This also ensures that the project is carried out safely, following the highest data security standards.

To build an in-house labeling team, you need to:

  • Allocate HR and financial resources

  • Develop a labeling tool or use ready-made solutions

  • Build a QA team for error risk reduction

  • Supervise the annotation team

To lead an internal labeling team effectively, the company must strike the right balance between strategic development and high-quality performance of labeling tasks. Still, it’s not a scalable solution due to operational issues and insufficient training data expertise, unless it’s managed by a tech giant. If not, a third-party support from data specialists, like we provide at Label Your Data, might be a smarter choice to make.

Data Annotation Outsourcing

Reasons to outsource your data annotation tasks

When comparing quality between in-house and outsourcing alternatives, the latter is often considered the most time- and cost-effective way to handle complex ML projects. If a company decides to outsource the labeling tasks to a third party, all the burden associated with an in-house option immediately casts off.

Most companies specializing in data annotation have state-of-the-art tools and software that allows clients to review their tasks and monitor the progress. Professional outsourcing partners also provide customized solutions to satisfy different ML projects’ needs.

Outsourcing data entry services, data labeling, or any other data-related service works well when there’s a clear vision of the rules and standards for the training data used to train the algorithm for a specific use case. Yet, the lowest price can undermine the quality and confidentiality of the annotated dataset, which directly affects the ML model. So pick your outsourcing partner wisely.

Besides, outsourcing inevitably entails the issue of finding a reliable and trustworthy service provider for labeling datasets whose service is built around the highest data security and privacy standards.
