Text Data Annotation Services for Document Classification and Content Understanding

Text Data Annotation Services
Text datasets support a wide range of AI applications including document categorization, content tagging, topic modeling, compliance automation, and information retrieval. Training these systems requires structured and consistent text annotations applied across large and diverse corpora.
DataVLab provides text data annotation services designed for teams building domain specific classifiers, search algorithms, document ranking systems, and content moderation tools. We annotate long form text, short messages, articles, transcripts, and structured business documents according to your taxonomy.Our services include document classification, topic tagging, summarization alignment, metadata extraction, labeling for content moderation, and text based relevance scoring. We adapt to specialized use cases such as legal document structuring, financial text categorization, e commerce product description tagging, customer feedback analysis, and internal knowledge base optimization.
Quality control combines multi stage review, guideline enforcement, and consistency checks across annotators. When required, we can deploy EU based teams for projects involving sensitive or proprietary text datasets.With workflows shaped around accuracy, repeatability, and large scale throughput, we help organizations prepare text datasets that are ready for training and fine tuning language models and classification systems.
Structured and consistent document annotation aligned with your taxonomy.
Scalable workflows suitable for large text corpora and high volume processing.
Support for specialized domain content including legal, financial, retail, and technical documents.
How DataVLab Supports Text Classification and Document Understanding
We design annotation workflows tailored to document level and corpus level understanding for enterprise and AI applications.

Document Classification
Assigning category labels to structured and unstructured text
We label documents across multi level taxonomies to support search indexing, content management, and automated routing.

Topic and Theme Tagging
Identifying themes in long form or short form content
We tag text with topic labels for training content discovery systems and improving information retrieval.

Metadata and Attribute Extraction
Assigning structured attributes from free text
We extract attributes such as category, priority, product type, compliance flags, and internal classifications.

Content Moderation Labeling
Analyzing compliance risks and sensitive content
We annotate policy violations, safety risks, sentiment thresholds, and content categories for moderation systems.

Summarization Support Datasets
Highlighting key statements and relevance markers
We tag important segments and provide relevance scoring to support training summarization and document ranking models.

Classification for E Commerce Descriptions
Structuring product text for catalog organization
We classify product descriptions, tag attributes, and ensure consistent categorization for catalog and marketplace AI.
