Our Data Annotation Services Workflow
Our quality-first workflow that delivers high-accuracy annotations at scale.

Dedicated project manager from LTS GDS conducts a comprehensive assessment to understand your business specific needs and project requirements. We analyze your data types, annotation specifications, quality standards, timeline, and deliverable expectations. Based on this analysis, we propose tailored AI data annotation solutions and provide expert consultation before project initiation.

Our vetted engineers kick off a pilot project using your sample dataset to demonstrate our capabilities and validate our approach. Our data annotators complete this small-scale test, allowing businesses to evaluate our work quality and methodology. Following delivery, our team leader collects your feedback to refine project specifications and finalize the Service Level Agreement (SLA) and contract terms.

Our project manager and HR department carefully select team members based on project's timeline, scope, and specific requirements. We then conduct comprehensive training sessions led by battle-hardened team leaders to ensure all annotators understand the guidelines, quality standards, and project objectives before beginning work.

Clear communication protocols between both parties are established, including regular check-in schedules, reporting procedures, and escalation processes. Both teams are involved in creating a detailed project timeline and implementing tracking systems that will be used consistently across all delivery teams throughout the project lifecycle.

Our annotation team executes the project according to the agreed plan while monitoring progress and key performance metrics. The dedicated project manager from LTS GDS maintains backup solutions for unexpected challenges and provides regular progress reports to keep businesses informed and enable timely adjustments when needed.

All annotated datasets undergo strict multi-stage quality assurance processes before delivery. Upon project completion, we conduct feedback sessions to gather insights and testimonials, helping us improve our services for future projects.

FAQs about Data Annotation Services for AI/ ML Models
What is data annotation?
Data annotation is the process of labeling various data types such as text, images, audio, or video to enable AI models to comprehend and learn from them. It's a crucial step in training AI and machine learning models to recognize patterns, make predictions, and automate decision-making.
Why is data annotation important for AI and machine learning?
High-quality annotated data is fundamental to the accuracy and reliability of AI systems. Without properly labeled data, machine learning algorithms cannot learn effectively, which can result in poor model performance and inaccurate outputs.
What types of data can be annotated?
We offer annotation services for diverse data types, including image, text, audio, video, time series, code, and multimodal annotation, etc.
What is the difference between manual and automated annotation?
Manual annotation is performed by trained experts and delivers higher accuracy often up to 99%, making it ideal for projects that demand precision and quality. Automated annotation is faster but less reliable for complex tasks, often requiring human review.
How do you ensure annotation quality and accuracy?
We ensure annotation quality and accuracy through multi-layered quality control mechanisms. These include a comprehensive QA process (self-check, cross-review, vertical review, and final random inspection), extensive annotation guidelines and training, and regular audits and performance tracking.
