Services

Natural Language Processing
Services We Deliver

Build NLP systems that understand, classify and extract useful information from human language.

Categorize

Text Classification

Automatically classify emails, documents, support requests and other text into defined business categories.

Common applications include email routing, ticket categorization, document classification, issue detection and content tagging.

Purpose

Intent Classification

Identify what a customer, employee or user is trying to accomplish from written or transcribed language.

Intent classification can support enquiries, service requests, call intake, support triage and workflow routing.

Entities

Named Entity Recognition

Identify and extract meaningful entities such as people, organizations, locations, dates, products, reference numbers and domain-specific terms.

Fields

Information Extraction

Transform unstructured language into structured fields that downstream applications can process.

Opinion

Sentiment Analysis

Analyze reviews, feedback, surveys and support interactions to identify sentiment and recurring opinion patterns.

Languages

Multilingual NLP

Process classification, extraction and language-understanding tasks across supported languages.

For generative language applications, model integration and fine tuning, explore our LLM Development Services.

Approach

NLP Models
and Technology

Not every language problem requires a large language model. We select the approach according to the task, available data and required level of accuracy.

Deterministic

Rule-Based NLP

Useful for workflows with highly deterministic terminology and well-defined language patterns.

Supervised

Machine Learning Models

Suitable for many classification and extraction tasks when representative labeled data is available.

Contextual

Transformer Models

Use contextual transformer models for more complex language-understanding requirements.

Adapted

Pretrained NLP Models

Adapt established models for classification, entity recognition and domain-specific tasks.

Generative

LLM-Assisted NLP

Use language models when they provide a measurable advantage for the specific language-processing task.

For deeper model engineering, explore our LLM Development Services.

Measurement

NLP
Evaluation

NLP systems should be measured against the task they actually perform.

Accuracy

Classification Accuracy

Measure whether text is assigned to the correct category.

Balance

Precision and Recall

Track false positives and missed examples for important classes.

Combined

F1 Score

Balance precision and recall when both are important.

Entities

Entity Accuracy

Measure whether required entities are identified correctly.

Fields

Field Accuracy

Validate extracted business values against expected results.

Per Language

Multilingual Performance

Evaluate supported languages individually instead of relying on one overall score.

Thresholds

Confidence Thresholds

Use model confidence to determine when automatic processing is appropriate and when human review is required.

Typical intents can include booking requests, support enquiries, pricing questions, service requests and department-specific enquiries.

  • Natural-language understanding
  • Intent classification
  • Structured request capture
  • Transcript processing
  • Caller-context extraction
  • Defined intent taxonomy

FAQ

NLP Services
FAQs

Straight answers on classification, entities, extraction, multilingual work and how NLP relates to language models.

Natural Language Processing services involve building software that analyzes and understands human language.

Common applications include text classification, intent recognition, sentiment analysis, named entity recognition and information extraction.

Text classification assigns predefined categories to written content.

It can be used for support tickets, emails, documents, customer feedback and other business text.

Intent classification identifies what a user is trying to accomplish from their language.

Different phrases can therefore map to the same underlying business request.

Named Entity Recognition identifies entities such as people, organizations, locations, dates, products and business-specific references inside text.

Information extraction converts unstructured language into structured information such as fields, entities, attributes or relationships.

Sentiment analysis identifies patterns of opinion or sentiment expressed in text.

It can be applied to reviews, surveys, support interactions and customer feedback.

Yes. Emails can be classified according to intent, department, urgency, topic or another defined business category.

Yes. Document classification can identify the type of document before extraction or downstream processing.

No. Many NLP problems can be solved with traditional machine learning, transformer models or rule-based methods.

The appropriate approach depends on the task, available data and required performance.

Natural Language Processing is the broader field concerned with computational understanding and processing of language.

Large language models are one family of models capable of performing many language tasks. For model engineering work, see our LLM Development Services.

NLP analyzes, classifies or extracts information from language.

RAG retrieves information from external knowledge sources before a language model generates an answer. See our RAG Development Services.

Yes. Multilingual NLP can support classification, entity extraction and other language-processing tasks across supported languages.

Each production language should be tested independently.

Common evaluation measures include accuracy, precision, recall, F1 score, entity accuracy and field-level extraction accuracy.

The appropriate metrics depend on the business task.

Yes. NLP services can integrate with CRM, ERP, ticketing systems, document workflows and custom business applications through APIs and application services. See our AI Integration & Implementation Services.

Yes. We can review training data, label quality, preprocessing, model selection, class balance, confidence thresholds, multilingual performance and production errors to identify where accuracy is being lost.
