What is a NLP platform?

NLP (Natural Language Processing)

NLP or Natural Language Processing consists in the processing of natural language by machines. Many algorithms fall under the NLP field: splitting a sentence into words, tagging part of speech, enriching words, etc...

NLU (Natural Language Understanding)

NLU is a sub-component of NLP which consists in this case of adding statistical learning (Machine Learning). The NLU intervenes to identify the intentions and meanings of natural language, to basically understand what the user is saying. In order to achieve this, NLU algorithms use NLP.

NLP Platform

A NLP platform is a SaaS (software as a service) that proposes NLP algorithms to integrate conversation interfaces with chatbots or other types of applications.

The most common NLP algorithms are:

  • Intent recognition: the ability to classify a user input to better understand his/her intent
  • Named Entity recognition (NER): being able to find entities within a sentence. Entities can be common entities such as measurements, locations, first names, etc..., or custom entities that have been trained.
  • Sentiment analysis
  • Tokenization: splitting a sentence based on words.
  • Parts Of Speech Tagging (POS): allows you to know the base root of words as well as word types (nouns, adj, etc...)

NLP platforms serve all this information over API so your conversational agent can get going within minutes.
