Language AI for the text your business already writes

Tickets, contracts, clinical notes, reviews. Most of it is read once and filed. We build NLP pipelines that extract, classify and route it, tuned on your vocabulary, scored per class and per language, and wired into the systems that act on the result.

Text in. Structured decisions out.

Six services. Each starts from a task your text already supports and a metric your team signs off.

Sentiment Analysis & Opinion Mining

Sentiment tied to the product, feature or person it's about, across tickets, reviews, chats and news. "Negative" on its own tells nobody what to fix.

Named Entity Recognition & Information Extraction

Parties, dates, amounts, clauses, drug names and part numbers pulled into fields, using models tuned on your own vocabulary and abbreviations.

Custom Chatbot & Conversational AI

Assistants that keep context across a conversation, answer from your knowledge base, and hand over to a person rather than guess.

Automated Document Processing & Classification

Invoices, contracts, medical records and filings read, classified and routed, including scanned pages where OCR noise is half the problem.

Intent Classification & Ticket Routing

Every email, chat and ticket tagged by intent and sent to the team that can resolve it. Uncertain cases are flagged for a person.

Multilingual NLP & Cross-Language Intelligence

Classification and extraction across languages, reported language by language, because performance rarely holds evenly outside the major ones.

Six phases, from raw text to a running pipeline

Each phase is named for the artefact it produces, so you can see exactly where the project stands.

Use cases and the cost of a wrong label

We look at the text you already hold - tickets, contracts, notes, reviews - and the decisions it could feed. Each candidate gets a value, a risk and a measure of success.

Some candidates stop here, because a keyword rule already does the job. That is a good outcome.

  • Ranked use-case list
  • Inventory of text sources and their owners
  • Metric per task, agreed in writing
  • Rules-versus-model decision per use case
  • Privacy and data-handling constraints
  • Phased plan for the chosen use case

Inside an enterprise NLP pipeline

Four stages. The choices made in each one set the ceiling for the next.

001

Ingestion & Cleanup

Text arrives from email, PDFs, scans, chat logs and databases. Language detection, OCR cleanup, de-duplication and redaction of personal data happen before any model sees it. Messy input is the most common reason accuracy disappoints.

002

Approach Selection

Rules, classic classifiers, encoder models such as BERT, or a tuned LLM. The cheapest approach that clears the agreed metric wins, because it will also be the cheapest to run at volume.

003

Task Pipelines

Extraction, classification, summarisation and translation each need their own metric and latency budget. They are built as separate containerised services that combine into larger workflows.

004

Monitoring & Retraining

Drift detection on inputs and outputs, corrections flowing back from the review queue, and a retraining pipeline that promotes a new model only when it beats the current one on the same test set.

Domain-Tuned NLP vs Generic API

Where the difference shows up in practice

Generic API

Broad

Trained for general text, not your tasks

  • Text processed on third-party servers
  • Weak on in-house terms and abbreviations
  • Opaque when it gets something wrong
  • Doesn't learn from your corrections
Nujtech Domain-Tuned NLP

Tuned

Trained and tested on your own tasks

  • Can run inside your own infrastructure
  • Tuned on your vocabulary and formats
  • Per-class results you can inspect
  • Retrained from reviewer corrections

From Rules to LLMs

From regular expressions to fine-tuned LLMs. The task, the data and the cost of running it at volume decide which layer does the work.

Fine-Tuning & Training

PyTorchTensorFlowLoRAQLoRARLHFPEFTScikit-learn

Chosen per task. The benchmark picks the approach, not a partnership.

Three places NLP projects go wrong.

None of them is the model. All of them surface after launch unless someone looks first.

Labels Nobody Agrees On

If two experts would tag the same ticket differently, no model will do better than they do. Disagreement is measured before training, not discovered after it.

A Good Average Hiding a Bad Segment

A strong overall score can hide failure on one language, one product line or one rare class. That is why results are broken out by segment.

A Model Where a Rule Would Do

Some extraction is a pattern match. Training a model for it adds cost, latency and drift risk, and buys nothing.

How we build language systems

Four habits that decide whether a text model survives contact with real documents.

01

Cheapest Approach First

Rules and small models are tested before large ones. You pay for model capacity only where the benchmark shows it's needed.

02

Results by Class and Language

Every report breaks performance down by category and by language, so weak spots are visible before your users find them.

03

Review Built Into the Flow

Uncertain outputs go to people, and their corrections become training data. The system improves from its own mistakes.

04

Data Stays Where It Must

Pipelines can run inside your cloud or on your own hardware, with personal data redacted before anything leaves the perimeter.

Common Questions

Use-case selection, labelling design, model selection and tuning, integration with your systems, validation, and monitoring after launch. The aim is to turn unstructured text into fields, labels and routes your systems can act on.

Pick one decision.
Measure before you build.

Tell us which decision a model should support and what a wrong answer costs. The first conversation covers your data and how the result will be judged. If an off-the-shelf model already passes, that is the answer you get.
