Natural Language Processing (NLP) refers to how humans and computers interact fundamentally with natural human languages. NLP is considered to be a subfield of Computer science and linguistics advancements like data science and artificial intelligence are playing a significant role. Generating and understanding natural languages and speech recognition of some of the actions associated with natural language processing.

In this article, you can gain a better picture of natural language processing using MATLAB where we will first start with an overview of it.

Overview of NLP using MATLAB

  • The source of human languages include social media, web data, audio files, documents, and other crucial databases of public sentiment, maintenance reports, voice commands, and operational data
  • NLP is involved in integrating and simplifying such huge sources of data thus transforming them to obtain deep perceptions using  visualization tools, classifiers based on machine learning, and topic models
  • It is really hard for humans to read and sort huge datasets whereas MATLAB provides a better platform to make this process are highly efficient
  • By using MATLAB you can detect patterns, analyze the trends and establish complex relationships

NLP Toolbox for Matlab

MatlabNLP is the NLP toolbox associated with MATLAB which contains appropriate models for or all types of natural language processing features such as the following

  • Tokenization and pre-processing – stemming, word removal, and text cleaning
  • POS tagging – identify the part of speech for the given sentence or words
  • Learning Algorithms – decision trees, linear regression, Naive Bayes, and support vector machines

Therefore MATLAB provides for a variety of benefits in natural language processing. Natural Language Processing using MATLAB allows us to determine the presence of the human voice in any audio file and establish transcripts from speech to text and apply machine learning algorithms and text mining techniques.
