Natural language processing is a subfield of computer science, artificial intelligence, and linguistics that studies the problems of automatic generation and understanding of natural human languages.

NLP, or PLN in Portuguese, performs three main tasks in its relation to content creation and SEO :

• recognize text;
• Understanding text;
• generate text.

The way machine learning

NLP text recognition

Computers are not yet able to work with plain text; they need to interact with numbers.

This therefore means that any NLP solution will need to convert the text we create into numbers so that computers can understand them. Machine learning is used for this.

NLP Reading Comprehension

After converting the text into a language that machines understand, that is, numbers, the algorithms will be able to perform the statistical analyses necessary to discover the words, terms, or topics that appear most frequently in a given text.

NLP text generation

After the recognition and comprehension stages, the NLP machine can use what it has discovered to ask questions or even make suggestions to a human being who will use them to write or improve what has already been written.

Today's most advanced machines are already starting to assemble some content summaries, giving human writers a more consistent starting point.

With the help of NLP and artificial intelligence (AI), writers will soon be able to generate content in less time, as they will only need to gather keywords and central ideas, and let the machine take care of the rest, but it will still take a long time for these machines to write something on their own that is at the same level as what a human being is capable of doing.
