2. Roles in the Project
Each annotation project on the TagOn platform allows users to participate in two distinct roles, each with specific responsibilities and requirements. Understanding these roles is crucial for choosing the right position that matches your skills and interests.
Role Selection
When registering for a project or stage, you must choose which role you want to perform. Important considerations:
- You can only choose one role per project: You cannot be both an Annotator and Reviewer for the same project simultaneously
- Role selection is stage-specific: You may choose different roles for different stages within the same project
- Role requirements vary: Each role has different skill requirements and test criteria
- Role availability: Not all projects may have openings for both roles
• Annotator (Anno)
The Annotator role is the primary data labeling position in annotation projects.
Responsibilities
Annotators are responsible for:
- Data Labeling: Performing the actual annotation work according to project guidelines
- Quality Standards: Ensuring annotations meet the specified quality criteria
- Guideline Adherence: Following all instructions, standards, and best practices provided
- Task Completion: Completing assigned work items within specified deadlines
- Correction Implementation: Making necessary corrections based on reviewer feedback
Skills Required
Successful annotators typically possess:
- Attention to Detail: Ability to notice subtle differences and follow precise instructions
- Consistency: Maintaining uniform annotation standards throughout the project
- Time Management: Completing tasks efficiently while maintaining quality
- Technical Proficiency: Comfortable using annotation tools and software
- Domain Knowledge: Understanding of the subject matter being annotated (when applicable)
Workflow
The typical annotator workflow involves:
- Receiving assigned work items (WIs)
- Reviewing project guidelines and instructions
- Performing annotations according to specifications
- Reviewing own work for accuracy and completeness
- Submitting completed annotations
- Addressing any feedback or correction requests from reviewers
• Reviewer
The Reviewer role focuses on quality assurance and evaluation of annotation work.
Responsibilities
Reviewers are responsible for:
- Quality Evaluation: Checking annotations submitted by annotators for accuracy and completeness
- Guideline Compliance: Verifying that annotations follow project guidelines and standards
- Scoring and Rating: Assigning quality scores to annotation work
- Feedback Provision: Providing constructive feedback to annotators when corrections are needed
- Final Approval: Approving annotations that meet quality standards
Skills Required
Successful reviewers typically possess:
- Expert Knowledge: Deep understanding of annotation guidelines and quality standards
- Analytical Skills: Ability to identify errors, inconsistencies, and quality issues
- Fair Judgment: Objective evaluation of work based on established criteria
- Communication Skills: Ability to provide clear, constructive feedback
- Experience: Usually requires prior experience as an annotator or domain expertise
Workflow
The typical reviewer workflow involves:
- Receiving annotations submitted by annotators
- Reviewing annotations against project guidelines and standards
- Identifying any errors, inconsistencies, or quality issues
- Providing scores and feedback
- Approving acceptable work or requesting corrections
- Documenting patterns or recurring issues for project improvement
Choosing the Right Role
When deciding which role to pursue, consider:
- Your Experience Level: Annotator roles are typically more accessible to newcomers
- Your Skills: Reviewers usually need more experience or specialized knowledge
- Your Preferences: Do you prefer creating annotations or evaluating them?
- Project Requirements: Some projects may have specific requirements for each role
- Earning Potential: Different roles may have different compensation structures
Users may choose either role for each stage, depending on the requirements of that specific stage and their own skill set. You are not locked into one role across all projects or stages.

3. Project Stages
Projects on the TagOn platform are organized into stages, which provide a structured approach to managing complex annotation projects. Understanding the stage system is essential for effective project participation and management.
Stage Structure
Each project is divided into multiple stages, with each stage representing a distinct phase of the annotation work. This modular approach offers several advantages:
- Focused Work: Each stage concentrates on one specific type of task
- Clear Progression: Stages provide a clear path through the project
- Flexible Participation: Users can join stages that match their skills and availability
- Quality Control: Each stage can have its own quality standards and review process
Stage Characteristics
Single Task Focus
- Each stage has only one specific task, and this task does not change throughout the stage
- This focused approach ensures clarity and consistency in the work
- Examples of stage-specific tasks:
- Stage 1: Object detection in images
- Stage 2: Classification of detected objects
- Stage 3: Attribute labeling for classified objects
Independent Work Modules
Each stage functions as an independent work module with:
- Its Own Requirements: Specific guidelines and standards unique to that stage
- Its Own Documentation: Stage-specific instructions, examples, and reference materials
- Its Own Test(s): Separate qualification tests that must be passed to participate
- Its Own Timeline: Individual deadlines and milestones
- Its Own Quality Criteria: Stage-specific evaluation standards
Benefits of the Stage System
The stage-based structure provides several advantages:
- Skill Matching: Users can join stages that align with their expertise
- Progressive Learning: Users can start with simpler stages and progress to more complex ones
- Workload Management: Users can participate in multiple stages at their own pace
- Quality Assurance: Each stage can be optimized for specific quality requirements
- Flexible Scheduling: Users can join stages when they have time available
Stage Navigation
To work with stages:
- Access Project Details: Open the project you want to participate in
- View Available Stages: Review the list of stages within the project
- Select a Stage: Click on a stage to view its details and requirements
- Review Stage Information: Read descriptions, documents, and requirements
- Register for Stage: Complete tests and registration process if interested
- Begin Work: Start receiving work items after approval
Stage Progression
Understanding how stages relate to each other:
- Sequential Stages: Some projects require completing stages in order
- Parallel Stages: Some projects allow working on multiple stages simultaneously
- Prerequisites: Some stages may require completing previous stages first
- Independent Stages: Some stages can be completed independently of others
