What We Do ?

What we do in Named Entity Recognition

We build custom named entity recognition (NER) systems that go far beyond generic tools. Our models are trained on your industry-specific language, regulatory needs, and business workflows, turning messy text into clean, structured, actionable data.

Domain-Tuned NER Models

We fine-tune models to extract entities specific to your field contracts, chemicals, product IDs, clinical terms, and more.

Multi-Level Entity Detection

Capture nested entities, compound names, and attributes within long-form or semi-structured text.

Transformer-Based Accuracy

We use BERT, RoBERTa, DeBERTa, and custom embeddings to achieve high F1 scores even in complex datasets.

Multilingual Entity Extraction

Detect people, places, and organizations across English, Arabic, Spanish, Chinese, and more.

Legal & Financial Document Processing

Extract clauses, case references, client entities, or monetary values from dense professional text.

E-commerce & Product Intelligence

Identify brands, SKUs, categories, and user intent from product listings or reviews.

Healthcare & Biomedical NER

Detect medications, conditions, procedures, and patient identifiers with HIPAA-aligned processing.

Visualization & Export Tools

Display extracted entities with UI overlays and export in JSON, CSV, or structured DB-ready formats.

Industry Adoption

Why Named Entity Recognition Is Transforming Enterprise NLP

Extracting precise entities isn’t optional; it’s central to reliable text understanding. named entity recognition structures chaos into actionable insights, making knowledge searchable, automatable, and strategically valuable.

At Rain Infotech, we specialize in delivering Named Entity Recognition that helps businesses, institutions, and innovators unlock the true potential of artificial intelligence through secure, scalable, and industry-ready applications tailored to real-world challenges.

Nested & Overlapping Entity Recognition

Extract multi-level entities like “CEO of OpenAI” or “$10M equity stake” with context-aware boundary detection.

Few-Shot & Weakly Supervised Learning

We reduce data requirements using prompt tuning, pattern mining, and distant supervision.

Multilingual & Cross-Lingual NER

Our models support multi-language corpora with translation alignment or multilingual embeddings.

Streaming Inference Pipelines

Deploy real-time entity recognition on incoming chat, email, logs, or documents.

Entity Disambiguation & Linking

Resolve entity ambiguity using context and knowledge bases, turn “Apple” into the right Apple.

Output Normalization & Standardization

Map extracted entities to ontologies, ICD codes, SKUs, or CRM tags for downstream automation.

Annotation Tools & Labeling Support

We offer annotation UI, label schema setup, and human-in-the-loop pipelines for fast data labeling.

Scalable Deployment Options

Run your NER stack on cloud, edge, or on-prem environments, containerized and API-ready.

Monitoring & Feedback Loop

Track accuracy drift, new entity types, and false positives with built-in review and retraining pipelines.

  • 03

    Model Selection & Fine-Tuning

    We select the right architecture (e.g., BERT, CRF, BiLSTM) and train it using your labeled examples validated with precision, recall, and F1 benchmarks.

  • 04

    Evaluation & Optimization

    We test on unseen data, tune hyperparameters, and refine entity boundary detection and class performance.

  • 05

    Deployment & API Integration

    We expose NER functionality via scalable, secure APIs, deploying to the cloud or on-prem based on your requirements.

  • 06

    Monitoring, Feedback & Iteration
