Natural Language Processing (NLP)

Nowadays, a great advance in technology has been achieved, to the point that machines have managed to perform tasks that we considered that only human beings could perform. For example, for a computer to interpret human speech was science fiction about 20 years ago, but today it is a reality. This technology is present in our daily routine. Using only the voice, you can send commands to the mobile phone or control the devices of a smart home.

Smartphone applications like Alexa, Siri, Google Assistant, among others, have made it easier to perform daily tasks such as scheduling activities or looking for a contact. All these types of applications use natural language processing and machine learning.

Definition - Natural Language Processing

Natural Language Processing involves interactions between computers and human languages. NLP enables processing and analyzing large amounts of natural language data using computers. It provides machines with the ability to understand natural human language.

Natural language processing is used in multiple tools or software, some examples of its use are:

1. Chatbots
2. Text summary
3. Sentiment analysis
4. Classification of texts
5. Automatic translation
6. Speech recognition

NLP tries to make human language comprehensible to a machine in five main areas: phonology, morphology, syntax, semantics and pragmatics.
