Linguamatics NLP provides varying levels of support for text mining non-English language documents. This page summarizes the most commonly available natural language processing (NLP) capabilities we have applied to non-English language documents. Our capability in this area is constantly evolving based on our customers’ requirements; below is a summary of the most commonly supported capabilities:

  • comprehensive, high quality NLP-based capabilities for English, Dutch, French, German, Italian, Portuguese, Spanish and Italian
  • support for Mandarin, including quantitative expressions and linguistic units.

If your preferred language is not yet included above, please speak to one of our consultants who will be able to provide further information about the current level of support available. A number of key capabilities enable our technology to analyze text in different languages; these are described below.

Pattern classes

Pattern classes enable the technology to match and normalize expressions such as dates, numbers, measurements and genetic mutations. Typically there is commonality across languages, though adaptation is required for items such as numbers, where words may be used instead of digits.

ANSI terminologies

The application of terminologies enables the technology to recognize concepts within the documents. Use of multilingual terminologies such as MedDRA (available in nine languages) can improve recall while preserving precision by:

  • searching for a concept and matching synonyms from multiple languages to improve recall
  • matching English synonyms only in English text, German synonyms only in German text, etc., to improve precision

Linguistics

A range of linguistic extraction techniques are used to transform unstructured text into structured, including:

  • tokenization, used to break down text words
  • stemming to identify the root of a word and recognize different variants with the same root
  • Part of Speech (PoS) tagging, which labels words according to their grammatical role (noun, verb, proposition)
  • chunking, which groups words together based on their PoS, for example grouping a verb and an adverb to form a verb group.
