How we deliver

  1. Phase_01

    Data & Domain Audit

    We analyze your text data (volume, language, domain vocabulary, quality) and define what structured output you need.

  2. Phase_02

    Pipeline Design

    Architecture for preprocessing, model selection, post-processing, and validation. Every pipeline is modular and testable.

  3. Phase_03

    Model Training & Tuning

    Fine-tuning transformer models on your domain data with rigorous evaluation on precision, recall, and real-world accuracy.

  4. Phase_04

    Integration & Monitoring

    API deployment, batch processing setup, drift detection, and continuous improvement based on production feedback.

Questions we hear

Yes. For multilingual classification, NER, and semantic search, we use multilingual transformer models -- XLM-RoBERTa and mBERT handle 100+ languages with strong performance on European and major Asian languages. Arabic, Hindi, and other morphologically complex languages typically need domain-specific fine-tuning on top of the multilingual base.

For text classification with a fine-tuned transformer, 500-2,000 labeled examples per class is usually enough for production quality. Named entity recognition needs 1,000-5,000 annotated sentences. If your labeled data is thin, we combine semi-supervised learning with active learning loops so you label efficiently rather than randomly.

Traditional NLP with fine-tuned transformers is faster, cheaper, and more deterministic -- ideal for high-volume classification, entity extraction, and structured output. LLMs handle ambiguous, open-ended tasks better but cost 10-50x more per token. Many of our production systems combine both: a fine-tuned classifier routes text, with an LLM handling only the cases that benefit from reasoning depth.

A classification or NER pipeline integrated into an existing API takes 4-8 weeks. Semantic search built on a document corpus takes 2-4 weeks. Document extraction from structured layouts runs 4-6 weeks. Conversational AI on a domain knowledge base takes 6-10 weeks. The biggest variable is labeled data availability at project start.

For binary classification on clean text, well-tuned models reach 90-97% F1. Multi-label classification over 20+ categories runs 80-88% micro-F1. NER on domain-specific entities reaches 85-93% F1 after fine-tuning. We report precision and recall separately because the right tradeoff depends on your use case.
