Features built for production text annotation

Text data is messy, ambiguous, and full of edge cases. Your labeling workflow should be the opposite: structured, fast, and easy to audit.
feature-image
Flexible labeling setup
Set up text annotation projects for classification, NER, sentiment, summarization, translation, and question answering. Define labels, attributes, and required fields so every annotator follows the same schema.
feature-image
Clear guideline enforcement
Bake rules into the workflow using required fields and validation checks. This reduces ambiguity, improves consistency, and keeps edge cases from becoming everyone’s personal opinion.
feature-image
Configurable QA workflows
Choose the right control level for each dataset, whether that means Maker-Checker for strict approvals, Maker-Editor for corrective reviews, or Majority Vote for subjective tasks.
feature-image
High-throughput task operations
Route work by priority and skill, batch tasks for speed, and keep queues moving without compromising consistency. Built for real-world volumes where delivery dates exist.
feature-image
Audit-ready traceability
Track who labeled what, what changed during review, and why it was approved. Useful for regulated data, repeated experiments, and debugging model behavior.
feature-image
Structured export for NLP and LLM pipelines
Export clean, structured datasets that plug into training and evaluation workflows. Less manual cleanup, fewer broken handoffs, and fewer “final_final_v3” files.

built scale
Summarisation
Create high-quality summarization datasets by labeling key points, required fields, and acceptable tone. This helps with agent assist, meeting notes, and shortening long customer threads without losing the one important line.
built scale
Translation
Build multilingual training data by labeling translation pairs and preferred terminology. This supports global support, cross-border commerce, and models that need domain-specific language understanding, not generic dictionary translations.
built scale
Sentiment analysis
Label sentiment and emotion consistently using consistent rules so you can track customer experience over time and build reliable classifiers. This is how you avoid dashboards that say “mostly positive” while your churn says otherwise.
built scale
Text classification
Tag text into custom categories, topics, and intents to make routing and automation more predictable. Works for ticket queues, inbox triage, compliance buckets, and any workflow where humans shouldn't be playing traffic cop.
built scale
Named-entity recognition
Extract structured entities from unstructured text by labeling names, products, dates, amounts, locations, and identifiers. Useful for contract processing, claims, KYC workflows, and search enrichment.

Taskmonk's workflow is built for faster text annotation with repeatable quality

Text datasets do not fail at the model stage. They fail when the workflow is fuzzy. This one keeps labels consistent from first batch to production scale
trust-icon
Import and organise
Bring in text records with metadata, queue work by priority, language, source, or difficulty, and start annotation with structure instead of sorting.
trust-icon
Define schemas and guidelines
lock down taxonomies for labels, standardize entity rules, and resolve edge-case decisions upfront. Ensure validation prevents multiple valid interpretations for the same input.
trust-icon
Annotate and review
Label in focused queues, then apply Maker-Checker, Maker-Editor, or Majority Vote based on subjectivity and risk. Resolve disagreements before they become a training signal.
trust-icon
Export and iterate
Export training-ready outputs, version schema changes, and rerun only updated items. Enable faster iterations and reduce relabeling pain.

FAQ

What is text annotation in NLP?
Text annotation adds structured labels to raw text, such as classes (categories of text), entities (e.g., names or locations), relations (how entities are connected), sentiment (emotional tone), and QA pairs (question-and-answer pairs), to help machine learning models learn patterns.
What types of text annotation does Taskmonk support?
Taskmonk supports labeling text by category, finding names, marking feelings and goals, translating, shortening, and making question-answer sets. You can adjust how you set up tasks and check quality.
How do you ensure quality in text data labeling?
Good labels come from clear instructions, simple checks, well-trained labelers, and review by others. If people don’t agree, set rules for hard cases and repeat until solved.
What file formats can I import and export for text annotation?
You can usually use CSV or JSON files to bring in your data, and export results in JSONL or CSV. You can include labels, text parts, reviewer choices, and version notes for clear future use.
Can Taskmonk help with LLM training datasets like summarization and question answering?
Yes. Taskmonk can help you create simple sets for summarizing or answering questions by marking the needed parts, providing information for answers, and using clear, quality steps that follow what you care about.
Do you offer managed text annotation services or only the platform?
You can use Taskmonk on your own, or have Taskmonk label your data from start to end, including setup, people, checks, and reports.
