NLP systems built on fine-tuned language models calibrated to your domain vocabulary, document types, and entity taxonomy -- not generic pre-trained models applied without adaptation. Document classification using fine-tuned BERT, RoBERTa, or DeBERTa for routing and categorisation: support ticket intent classification (billing inquiry, technical issue, cancellation, feature request), legal document type identification, financial report section tagging, or clinical note category assignment -- each model fine-tuned on your labelled documents rather than relying on zero-shot generalisation. Named entity recognition (NER) for extracting structured data from unstructured text: company names, people, dates, monetary amounts, locations, medical terms (conditions, medications, procedures using UMLS coding), legal parties and clauses, and custom entity types specific to your domain (product SKUs, account numbers, regulatory citations). Fine-tuned on your documents using Hugging Face's transformers library with your custom NER label schema. Sentiment analysis for customer feedback, review monitoring, and support ticket prioritisation: three-class (positive/neutral/negative) or multi-dimensional sentiment (satisfaction, frustration, urgency) depending on the downstream use case. Text summarisation for condensing long documents (contracts, research reports, clinical records) to key points using abstractive summarisation with fine-tuned T5 or BART models. Inference deployed as a FastAPI endpoint -- your application sends text and receives structured JSON output (labels, entities, sentiment scores) in milliseconds.
