What does an NLP Engineer do?


NLP Engineers are responsible for the interaction between everyday human language and a computer’s ability to process and analyze natural language data. But, what are the day to day tasks of a natural language processing engineer?

What is Natural Language Processing?

NLP Engineer - The role

Natural language processing (NLP) comes from an amalgamation of computer science, Information sciences, AI, and linguistics. NLP focuses on the interaction between computers and human languages.

While computers excel at the handling of structured datasets, they require a little help when it comes to human languages with hundreds of different languages and dialects, all with their own set of grammar rules, slang, terms, and syntax.

Ever wonder how Google or Alexa can understand what you’re saying? That’s NLP in play! And therefore NLP Engineers are responsible for the programming behind technology’s ability to process and analyze natural language data.

What are the responsibilities of an NLP Engineer?

NLP Engineer Responsibilities

Responsibilities as an NLP or Language Engineer will differ based on the type of industry you work for. In general, however, NLP Engineers are responsible for the development and design of language understanding systems and for the effective use of text representation techniques.

This can involve dealing with speech patterns, AI speech recognition, understanding of natural languages, and natural language generation.

Furthermore, they work on scripts to analyze and process text data, while measuring the accuracy of language understanding.

Responsibilities of a natural language processing engineer:

  • Design and develop natural language processing systems
  • Define appropriate datasets for language learning
  • Use effective text representations to transform natural language into useful features
  • Develop NLP systems according to requirements
  • Train the developed model and run evaluation experiments
  • Find and implement the right algorithms and tools for NLP tasks
  • Perform statistical analysis of results and refine models
  • Constantly keep up to date within the field of machine learning
  • Maintain NLP libraries and frameworks
  • Implement changes as needed and analyze bugs
