Product Features

Unleashing the power of advanced semantic intelligence

Foundational NLP

  • Accurate language identification — Automatically detects the language of each document or query with high reliability even in multilingual or code-switched data.
  • Tokenization — Splits unstructured text into words, phrases, or other meaningful units, respecting linguistic nuances.
  • Morphological analysis — Breaks down words into roots, stems, prefixes, and suffixes to interpret grammatical structure, inflection, and derivation.
  • Lemmatization — Reduces words to their base or dictionary form (lemma), allowing semantically similar words to be grouped for more effective matching.
  • Part-of-speech tagging — Assigns grammatical categories, enabling syntactic parsing and allowing for more accurateinterpretation of query intent and document meaning.
  • Named entity recognition (NER) — Automatically detects and classifies proper names to enrich search results and support entity-based retrieval.
