Natural Language Processing

Computers are the foundation of any business, and they have the ability to read information. Also, they have microphones that collect sound. A program helps to process these inputs, which are changed to a code that is easy for the machine to understand.

Natural Language Processing

Natural language processing is a branch of artificial intelligence that gives computers the ability to understand speech and text in the same manner as a regular human. It is a combination of computerized linguistics and structural and machine learning. In other words, its goal is to create a machine that interacts like a person. As technology grows, NLP becomes much more common in everyday situations. Also, it plays a key role in streamlining business operations, heightening worker productivity, and simplifying a business’s processes.

Why is NLP important?

Natural language processing provides a business with a helpful tool that may monitor a large volume of user content across all digital platforms. By using this tool, a company can engage with customers by answering their questions and addressing their concerns in a more efficient manner. Basically, NLP helps to resolve language ambiguity and offers helpful numeric structure to data for applications like text analysis and speech recognition.

Techniques and Methods of NLP

Two of the major techniques involved with NLP are semantic analysis and syntax.


Syntax is the way that words are arranged in a sentence so that everything makes sense grammatically. Natural language processing utilizes syntax to obtain necessary meaning for language, which is based on common rules of grammar.

  • Stemming. This is a set of algorithms that clips the end of starting words in order to reach its infinitive form. In other words, when the root of a word is identified, it becomes easier to analyze.
  • Word Segmentation. This occurs when a string of text is obtained. Words are derived from this text. For instance, a handwritten document is scanned so that it is possible to recognize words that are divided by white space.
  • Parsing. This occurs when a sentence is analyzed grammatically.


Semantics includes the meaning behind words and how they are used.

  • Named Entity Recognition. This is the most basic technique in natural language processing. It identifies entities, including people, places, dates, and organizations from text. It is based on rules of grammar and supervised notes.
  • Sentiment Analysis. This is the most common type of NLP. It is used most often for customer service development, social media comments, and customer feedback. The output creates a score that helps to choose the most positive and negative parts of a review.
  • Text Summarization. This NLP technique summarizes large batches of text. Mainly, it is used for research or news articles. This technique involves extraction and abstraction. Extraction creates a summary after taking parts from a text. Abstraction creates a rundown after creating new text that summarizes the original words.

What is the Role of NLP?

Natural language processing is used to comprehend the structure and meaning of language. It analyzes various things like syntax, pragmatics, semantics, and morphology. There are many real-world applications to NLP. In this manner, numerous fields and industries gain great advantages.

  • Customer Service Automation. When a customer calls for help and receives a voice assistant, natural language processing uses speech recognition to comprehend the inquiry so that the person can be directed to the correct party.
  • Automatic Translation. This is present in tools like Google Translate and similar software.
  • Customer Feedback Analysis. This occurs as artificial intelligence analyzes reviews on social media.
  • Organization of Medical Records. NLP helps to deal with mounds of paperwork and medical-related data that is difficult to sort through without assistance. In this manner, it can protect and prevent illness.
  • Proofreading. Writers use software like Grammarly to correct and detect plagiarism and other grammar mistakes.
  • Financial Trading. Natural language processing is often used to analyze stock trends. For example, artificial intelligence is used to analyze the history of the market and to deliver summaries of a business’s financial performance.

In many ways, NLP is used to interpret text so that it can be analyzed. There are countless data stored in free text files, especially in the medical industry. Thanks to this technology, it is possible to get through the piles of information in an efficient and successful manner without the need to hire an enormous staff of people.

Finally, natural language processing can be used for sentiment analysis. In other words, it is possible to review social media comments and rate how a company’s brand is performing. Also, it makes it easier to assess notes from customer service centers and to pinpoint places where a company may perform better.

Benefits and Challenges of NLP

There are both benefits and challenges that come from natural language processing. Although this technology is not new, it is becoming more and more popular. Recognizing the pros and cons will help a business gain the most advantages.


In all ways, NLP enhances how people and computers communicate. When a computer understands human language, it becomes easier to interact with customers.

  • Automation in Real-Time. Natural language processing tools assist machines with learning how to sort data without human interaction. This makes processing faster, more effective, and more accurate.
  • Perform Large-Scale Analysis. To repeat, this technology helps computers comprehend and analyze large drops of unstructured data. These include online reviews, social media comments, and other customer support inquiries.
  • Can Be Tailored to a Particular Industry. Not all fields of business are the same. The algorithm associated with NLP can be customized to a company’s particular needs. It is possible to get very specific with different industry terminology so that nothing gets misunderstood.


Although natural language processing brings advantages to businesses, there are some challenges to consider.

  • Context. In the English language, the same word may have different meanings. It becomes difficult for this type of technology to grasp the proper context. For example, homonyms make it difficult to decipher certain words for speech-to-text applications.
  • Ambiguity. Ambiguity occurs when a phrase has different potential interpretations. It becomes challenging with both semantics and syntax to correctly identify the meaning of the statement.
  • Slang. Informal expressions or cultural lingo can be difficult to understand within NLP technology. Luckily, with enough data and with a custom model, it may be possible to have slang words accurately analyzed.
  • Tone of Voice. Many natural language processing algorithms often miss subtle changes in a person’s tone of voice during speech recognition. This is especially true for people who speak with accents.
  • Change in Language. Language constantly changes. There are rules to every language, but things evolve all the time. This may become a roadblock to NLP.

Reasons to Consider Incorporating Natural Language Processing into Your Business

Thanks to the great advancements in technology, computers have become smart enough to understand humans and to communicate with them through spoken language. It is certain that this technology provides businesses with great benefits. To be sure, NLP is still evolving so that it becomes even better. By comprehending the fundamental techniques that make it work, it is possible to successfully incorporate them into everyday business tactics and reap the rewards, including higher productivity and streamlined processes.
