Overview
Natural language processing turns text into structured signals: categories, entities, sentiment, topics, intents and relationships. We build NLP systems using the right mix of fine-tuned transformer models, LLMs and classical techniques — optimised for accuracy, throughput and cost at your volume — for use cases from ticket routing and compliance screening to search relevance and voice-of-customer analytics.
Common use cases
- Ticket and email routingAutomatic categorisation and prioritisation of inbound text.
- Entity extractionNames, amounts, dates, products and clauses pulled from documents.
- Voice of customerSentiment and topic analysis across reviews, surveys and calls.
- Multilingual processingUnderstanding and normalising content across languages.
Quick answers
NLP Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is NLP development?
- Natural language processing for classification, entity extraction, sentiment, search and multilingual text understanding.
- Who is it for?
- Typically product companies adding AI features, enterprises automating knowledge work, and teams whose AI pilot needs to become a dependable production system.
- What does Shivacha provide?
- Text classification
- Named entity recognition
- Semantic search
- Topic modelling
- High-throughput pipelines
- Annotation workflows
- Which technologies are used?
- Python, MLOps, Computer Vision, Natural Language Processing, Speech AI, AI Inference & Serving — chosen to fit your stack and constraints.
- How does the process work?
- Frame the prediction → Audit the data → Baseline then improve → Deploy with MLOps → Monitor and retrain.
- What affects the cost?
- Number and quality of data sources
- Accuracy targets and evaluation effort
- Integrations with business systems
- Model choice, hosting and per-request cost
- Human-in-the-loop and audit requirements
- Data residency and privacy constraints
- How long does it take?
- A scoped proof of value usually takes 4–8 weeks; a production system with evaluation, integrations and guardrails typically takes 3–6 months.

Capabilities
What we deliver
Text classification
Multi-label classifiers trained on your taxonomy.
Named entity recognition
Domain-specific entity models and linking.
Semantic search
Embedding-based search and similarity.
Topic modelling
Unsupervised discovery of themes in large text collections.
High-throughput pipelines
Efficient batch and streaming processing.
Annotation workflows
Labeling tools and guidelines for training data.
Architecture
Engineered right from day one
The layers we typically design for machine learning, NLP & computer vision, adapted to your stack and partners.
- ExplainabilityFeature importance and reason codes where decisions affect customers.
- Data leakageRigorous validation splits so offline accuracy reflects production reality.
- Latency budgetsModel size and serving architecture matched to real-time requirements.
- FairnessBias testing across relevant segments for decisions with customer impact.
Delivery
How an engagement runs
- 1
Frame the prediction
Define the target, decision it supports, acceptable error and business metric.
- 2
Audit the data
Assess availability, quality, leakage and labeling needs before modeling.
- 3
Baseline then improve
Start with simple, explainable baselines and add complexity only when it pays.
- 4
Deploy with MLOps
Versioned models, reproducible pipelines and automated deployment.
- 5
Monitor and retrain
Track drift and performance in production and retrain on a schedule or trigger.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Data boundaries
Permission-aware retrieval so users only see answers from documents they may access.
Guardrails
Input and output checks, tool allow-lists and human approval for consequential actions.
No training on your data
Provider settings and contracts chosen so your data is not used to train third-party models.
Audit trail
Prompts, sources, tool calls and approvals logged for review.

Frequently asked questions
Should we use an LLM or a fine-tuned small model for classification?
LLMs are fast to prototype and handle nuance; small fine-tuned models are cheaper and faster at high volume. A common path is to prototype with an LLM, then distil into a smaller model.
Do you support languages other than English?
Yes. Multilingual models support many languages; performance varies, so we evaluate on your target languages.
How much data do we need?
It depends on the problem. Some tasks work with a few thousand labeled examples, especially with pre-trained models; others need much more. A short data audit gives a reliable answer before significant investment.
Can models run on devices or at the edge?
Yes. We optimise and quantise models for mobile, embedded and edge hardware where latency, connectivity or privacy require local inference.
