THE CHALLENGE
The Meaning Isn't Always in the Words
A customer writes, “That's just great.” Depending on the conversation, they could be genuinely pleased or expressing frustration. The words are the same, but the meaning is different.
AI models need examples that show how language works in context. Without those examples, they can miss intent, confuse similar expressions, or assign the wrong meaning to a message.
Anotag helps turn raw text into labeled examples that reflect the distinctions your application needs to recognize.
Understand Intent
Help models distinguish between questions, requests, complaints, feedback, and other communication goals.
Identify Important Details
Mark relevant names, dates, organizations, products, within text for accurate data extraction and analysis.
Make Text Usable
Turn unstructured language into organized examples for training, search, classification, and other AI tasks.
TEXT ANNOTATION CAPABILITIES
Give Every Piece of Text a Clear Purpose
The right annotation depends on what your model needs to learn. We label language at the level of detail your application requires, from identifying a person's name to understanding the purpose of an entire message.
.avif)
Sentiment Analysis
Label expressed opinions as positive, negative, neutral, or other sentiment categories required by the project.
(1).avif)
Named Entity Recognition (NER)
Identify people, organizations, locations, dates, products, and other defined entities in text.
.avif)
Intent Classification
Identify what someone wants to do, such as request a refund, ask a question, or get technical help.
.avif)
Semantic Annotation
Label meaning and context to help models distinguish between words or expressions with different interpretations.
.avif)
Text Classification
Assign documents or passages to categories based on their subject, purpose, or defined criteria for easier organization and retrieval.
.avif)
Content Moderation
Identify text that may violate defined policies, including abusive language, harmful content, or restricted material.
.avif)
Topic Labeling
Group text by subject or theme to support document organization, content discovery, detailed analysis, and insights.
Relationship Annotation
Label connections between entities, such as a person and their organization or a product and its manufacturer.
.avif)
Custom Text Annotation
Create labeling rules for specialized terminology, industry-specific language, or application-specific requirements.
ANNOTATION DEPTH
Label Text at the Level Your Model Needs
A document, a sentence, and a single word can each carry different information. The annotation level determines exactly where a label is applied and how much detail the resulting dataset contains.
The aim is to capture the right information, not to label more text than the task requires.
AUDIO ANNOTATION PROCESS
From Raw Text to a Dataset Your Team Can Use
We start with the purpose of the project, establish how the text should be labeled, and work through review before preparing the final dataset for your AI workflow.
AI + HUMAN ANNOTATION
Let Automation Handle the Repetition. Keep People in the Loop.
Automated tools can suggest labels and speed up routine work. But a sentence can be sarcastic, a word can have several meanings, and industry terminology can change how a passage should be interpreted.
The workflow should match the task: automate where the rules are clear, and bring in human judgment where the meaning needs closer attention.
AI-Assisted Labeling
Generate initial label suggestions to reduce repetitive work on suitable text datasets and speed up review.
​Human Review & Validation
Review ambiguous wording, sarcasm, context-dependent meaning, and labels that need closer judgment.
Rule-Based Checks
Check required fields, permitted categories, and formatting against the project's specifications.
Domain-Specific Review
Apply relevant language and subject knowledge when specialist terminology affects the correct label.
TEXT ANNOTATION QUALITY
Make Labeling Decisions Consistent Across the Dataset
A label is only useful if it is applied the same way to similar examples. Quality checks help identify where interpretations differ, rules are unclear, or the data does not meet the project's requirements.
Clear Label Definitions
Give annotators examples and decision rules for each category, including difficult cases.
Context Checks
Confirm that labels reflect the passage's meaning rather than relying on individual words alone.
Agreement Reviews
Compare annotations across reviewers or samples to find differences in interpretation.
Ambiguity Checks
Examine examples where a phrase could fit multiple categories or its meaning is unclear.
Data Validation
Check for missing labels, invalid categories, incomplete records, and formatting issues.
Guideline Improvements
Use recurring review findings to clarify instructions and reduce repeated mistakes.
DOMAIN & SCALE
Text Annotation for the Language Your Industry Uses
Every field has its own terminology and communication patterns. Annotation needs to reflect those differences instead of applying the same labels to every dataset.
WHY ANOTAG
A Text Annotation Partner That Fits Your Workflow
Your team should not have to reshape its entire process around its annotation partner. The work should fit the task, the data, and the way your team plans to use the results.
Language-Focused Expertise
Handle tasks that depend on context, terminology, and distinctions between similar expressions.
Flexible Workflows
Match the labeling approach to your task instead of forcing every project into the same process.
Project-Specific Guidelines
Define labels and decision rules around your application's specific requirements and use cases.
Flexible Project Scale
Plan annotation capacity around dataset volume, complexity, and delivery expectations.
Agreed Delivery Formats
Receive annotated data in the structures and formats specified for your downstream workflow.
Workflow Compatibility
Align delivery requirements with your existing NLP, machine learning, or data-processing environment.
SECURITY & DELIVERY
Keep Sensitive Text Under Control
Text projects can involve customer conversations, internal documents, or other confidential information. Access, transfer, and delivery requirements should be agreed before work begins.
Encrypted Transfers
Protect project files during transfer using agreed secure transmission methods.
Controlled Access
Restrict access to authorized personnel according to project permissions.
Defined Data Handling
Follow agreed procedures for managing, processing, and retaining project information.
Privacy Requirements
Establish applicable contractual, privacy, and regulatory obligations before annotation begins.
Controlled Delivery
Return completed datasets through agreed channels in the required formats.
