WHAT ANGO HUB OFFERS

Ango Hub supports text annotation as part of a broader AI data platform, combining workflow automation with expert-in-the-loop delivery. iMerit works on your text and document data to produce high-quality ground truth for NLP and LLM use cases, with consistent schema adherence from labeling through review.

WORKFLOW MANAGEMENT

Run structured text programs with configurable roles, routing, and handoffs. Centralize instructions and manage tasks across labeling and review so teams stay aligned on schema and edge cases.

BUILT-IN QUALITY CHECKS

Maintain gold-standard ground truth with structured review, benchmarking, and real-time issue resolution. Keep entity boundaries, relation logic, and classification decisions consistent across annotators and time.

AUTOMATION

Accelerate annotation with model-assisted workflows that reduce manual effort. Import model outputs and pre-labels to jump-start entity and classification work, then refine with human review for dependable final ground truth.

INTEGRATIONS

Plug into your stack with SDK and API support, model plugins, and webhooks. Automate handoffs into downstream pipelines so your teams can iterate faster.

ANALYTICS

Track throughput and quality trends with reporting that shows what’s completed, how it’s performing, and where to optimize guidelines or retrain for better consistency.

SECURITY AND GOVERNANCE

Support sensitive text programs with role-based permissions and governed workflows. Enable compliance-ready handling for regulated requirements, including PII-aware processes when needed.

CASE STUDY

Indexing 111 Years of Ancestry with Professional Data Annotation

.American Ancestors partnered with iMerit to digitize and index more than 1,300 books of sacramental records containing vital information from 1789 to 1900,. Because the project’s massive scale exceeded the capacity of their traditional volunteer-led approach, the organization utilized iMerit’s specialized experts to transcribe and assess complex handwritten documents,. The result was the creation of a searchable database featuring over 14 million names, allowing users worldwide to discover tangible connections to their family history.

Frequently Asked Questions

Ango Hub supports the full range of NLP and LLM data needs: named entity recognition (NER), relation extraction, text classification, intent and entity labeling for chatbots, sentiment analysis, document field extraction, search relevance judgments, content moderation labeling, and compliance and risk detection. Whether you're building a domain-specific LLM or tuning a general-purpose assistant, the platform is built for schema-consistent, high-volume text annotation.

Consistency starts with schema. Ango Hub enforces structured workflows with centralized guidelines, pre-label imports, and adjudication processes that resolve annotator disagreements systematically. iMerit's reviewers handle edge cases, domain terminology, and ambiguous language with defined rules — so entity boundaries, classification decisions, and relation labels stay consistent across thousands of tasks and multiple annotators.

Yes. iMerit's text annotation platform is actively used in healthcare (clinical text coding, triage, summarization), fintech and insurance (claims processing, risk signal detection, entity extraction from policies), and government (document processing, compliance monitoring). The platform supports PII-aware workflows, governed access, and enterprise-grade security for teams working with sensitive or regulated source data.

Yes. Ango Hub allows you to import model outputs and pre-labels to jump-start annotation, which dramatically reduces manual effort on high-volume programs. Teams can use automation to handle the straightforward cases and route ambiguous or difficult tasks to human reviewers — creating a scalable human-in-the-loop pipeline that improves both speed and accuracy.

iMerit's text annotation platform serves AI and NLP teams across technology platforms (LLM and chatbot training), healthcare (clinical documentation), fintech and insurance (document AI), retail and e-commerce (search relevance, catalog labeling), telecom (intent routing, churn analytics), and government (case management, compliance). Any team that needs structured, reliable labeled text for model training or evaluation can benefit from iMerit's combination of Ango Hub and expert delivery.
