Importance of Natural Language Processing 

Natural Language Processing, or NLP, is a subdomain of artificial intelligence and focuses primarily on interpretation and generation of natural language. It helps machines or computers understand the meaning of words and phrases in user statements. The most prominent highlight in all the best NLP examples is the fact that machines can understand the context of the statement and emotions of the user.

NLP works through normalization of user statements by accounting for syntax and grammar, followed by leveraging tokenization for breaking down a statement into distinct components. Finally, the machine analyzes the components and draws the meaning of the statement by using different algorithms. 

The working mechanism in most of the NLP examples focuses on visualizing a sentence as a ‘bag-of-words’. NLP ignores the order of appearance of words in a sentence and only looks for the presence or absence of words in a sentence. The ‘bag-of-words’ algorithm involves encoding a sentence into numerical vectors suitable for sentiment analysis. For example, words that appear frequently in a sentence would have higher numerical value.

It is important to note that other complex domains of NLP, such as Natural Language Generation, leverage advanced techniques, such as transformer models, for language processing. ChatGPT is one of the best natural language processing examples with the transformer model architecture. Transformers follow a sequence-to-sequence deep learning architecture that takes user inputs in natural language and generates output in natural language according to its training data.

Everyday Examples of Natural Language Processing 

The review of best NLP examples is a necessity for every beginner who has doubts about natural language processing. Anyone learning about NLP for the first time would have questions regarding the practical implementation of NLP in the real world. On paper, the concept of machines interacting semantically with humans is a massive leap forward in the domain of technology.

What can you achieve with the practical implementation of NLP? Just like any new technology, it is difficult to measure the potential of NLP for good without exploring its uses. Most important of all, you should check how natural language processing comes into play in the everyday lives of people. Here are some of the top examples of using natural language processing in our everyday lives. 

The most common communication tool for everyone in the world is electronic mail or email. Did you know that the most common NLP examples in real world include email filters? A working professional sends and receives almost 121 business emails every day. You must have a clear idea about the complexity of managing your inbox.

On top of it, you would have to deal with the issues of spam emails. Interestingly, email service providers can leverage natural language processing to automatically filter out unwanted emails. Training of an NLP model by using a training dataset featuring past emails could help it in detecting spam. 

It is important to note that email service providers could use NLP for other tasks beyond spam classification. You can review NLP examples like Gmail to identify smarter ways to leverage natural language processing to your advantage. Gmail utilizes natural language processing for creating smart replies or automatic response generation. It also offers the advantage of automatically marking messages as ‘Starred’ and ‘Important.’ With the power of NLP, Gmail enhances its email filters with suggestions for follow-up on certain emails.

  • Personalized Recommendations 

Online business has become a major highlight in the domain of technology. Online retailers have identified the importance of personalized recommendations for empowering their source of revenue. It is important to note that customers don’t always look for items that are in stock or the ones on sale. On the contrary, customers want products that can fulfill their needs while aligning with their values. For example, the recommendation engine of Amazon drives around 35% of the sales on its e-commerce platform. 

The outline of natural language processing examples must emphasize the possibility of using NLP for generating personalized recommendations for e-commerce. How can NLP achieve such tasks? NLP models could analyze customer reviews and search history of customers through text and voice data alongside customer service conversations and product descriptions.

The models could subsequently use the information to draw accurate predictions regarding the preferences of customers. Businesses can use product recommendation insights through personalized product pages or email campaigns targeted at specific groups of consumers. 

  • Analysis of Unstructured Data

The most prominent highlight in the debate between NLP and machine learning is the fact that NLP could support unstructured data. Machine learning algorithms must rely on structured datasets. On the contrary, over 80% of available data is in unstructured form, distributed across news articles, emails, books, customer reviews, and user comments. 

Interestingly, the response to “What is the most popular NLP task?” could point towards effective use of unstructured data to obtain business insights. Natural language processing could help in converting text into numerical vectors and use them in machine learning models for uncovering hidden insights.

For example, NLP can take thousands of unstructured documents about a business, including earning transcripts, customer reviews, and quarterly reports as inputs. NLP algorithms could use unstructured inputs for identifying and tracking crucial metrics, including sales growth, competitive differentiation, and customer sentiment.
