7 Best Natural Language Processing (NLP) Apps - GeeksforGeeks (2023)

In the past, have you ever imagined that you could use your phone to talk and get things done? Or that your phone would answer you! Nowadays, it has become pretty standard with Siri, Alexa, Google Assistant, etc. You can ask any question from "What's the weather like outside" to "What's your favorite color?" from Siri and you will receive a response. All this and much more is achieved withnatural language processing. Plus, there are plenty of other natural language processing apps out there these days, including the translator on your phone or the grammar checker you use before you send an email.

7 Best Natural Language Processing (NLP) Apps - GeeksforGeeks (1)

Natural language processing allows your device to listen to what you say, understand the hidden meaning of your sentence, and ultimately act on that meaning. And it's all done in 5 seconds! But the question that arises is what exactly is natural language processing? And how it works? So let's see the answer to that first.

Was it Natural Language Processing?

Natural language processing is a part of artificial intelligence that aims to teach computers human language with all its complexities. In this way, machines can understand and interpret human language to better understand human communication. Natural language processing is a crossroads between many different fields such asartificial intelligence, computational linguistics, human-computer interaction, etc. There are many different methods in NLP for understanding human language, including statistical and machine learning methods. This involves breaking down human language into its most basic parts and then understanding how those parts relate to each other and work together to make sentences meaningful.

And why is natural language processing important, you ask? Well, it allows computers to understand human language and then analyze large amounts of data based on the language in an unbiased way. This is very difficult for humans to achieve. Furthermore, there are thousands of human languages ​​in hundreds of dialects spoken in different ways and in different ways. NLP helps resolve ambiguities in language and create structured data from a very complex, confusing and unstructured source.

Because of this, natural language processing nowadays has many different applications in fields ranging from IT to telecommunications and science. Let's look at these apps now.

Natural language processing applications

1. Chatbots

Chatbots are a form of artificial intelligence programmed to interact with humans in a way that makes them appear human. Depending on the complexity of chatbots, they can simply respond to certain keywords or even have entire conversations that make them difficult to distinguish from humans. Chatbots are built using natural language processing and machine learning, which means they understand the complexities of the English language and find the true meaning of the sentence, as well as learn from their conversations with humans and improve over time. Chatbots work in two simple steps. First, they identify the meaning of the question being asked and collect any user data that may be needed to answer the question. Then answer the question accordingly.

2. Autocomplete in search engines

Have you ever noticed that search engines tend to guess what you're typing and automatically complete your sentences? For example, if you type "game" into Google, you'll get more suggestions for "Game of Thrones", "Game of Life" or, if you're interested in math, "Game Theory". All of these suggestions are provided by autocompletion, which uses natural language processing to guess what you want to ask. Search engines use their massive data sets to analyze what your customers are likely to type when they type certain words and suggest the most common choices. They use natural language processing to understand these words and how they fit together in different sentences.

3. Voice Assistants

Voice assistants are all the rage these days! Be it Siri, Alexa or Google Assistant, almost everyone uses one to make calls, set reminders, schedule meetings, set alarms, browse the web and so on. These voice assistants have made life so much easier. But how do they work? They use a complex combination of speech recognition, natural language understanding and natural language processing to understand what people are saying and respond to it. The long-term goal of language assistants is to bridge the gap between humans and the Internet and offer all kinds of services based solely on voice interaction. However, they are still a little far from that goal, as sometimes Siri still cannot understand what you are saying.

4. Language Translator

Do you want to translate a text from English to Hindi but don't know Hindi? Then Google Translate is for you! While it's not 100% accurate, it's still a great tool for converting text from one language to another. Google Translate and other translation tools, and using Sequence for sequencing modeling, a natural language processing technique. It allows the algorithm to convert a sequence of words from one language to another, which is the translation. Language translators used to use Statistical Machine Translation (SMT), which meant looking at millions of documents already translated from one language to another (English to Hindi in this case) and then looking for common patterns and vocabulary. However, this method was not as accurate compared to sequence-by-sequence modeling.

5. Sentiment analysis

Almost everyone is on social media these days! And companies can use sentiment analysis to understand how a certain type of user feels about a topic, product, etc. in particular. They can use natural language processing, computational linguistics, text analysis, etc. to understand the general sentiment of users towards their products. and services and find out whether the sentiment is good, bad, or neutral. Businesses can use sentiment analysis in many ways, for example, B. know the emotions of their target group, understand product reviews, assess brand sentiment, etc. And not only private companies, but also governments use sentiment analysis to determine public opinion. and also recognize any threat to the nation's security.

6. Grammar Checker

Grammar and spelling are very important factors when writing professional reports for your bosses, even term papers for your professors. After all, big mistakes can get you fired or suspended! Because of this, grammar and spell checkers are a very important tool for any professional writer. Not only can you correct grammar and check spelling, but you can also suggest better synonyms and improve the overall readability of your content. And guess what, they use natural language processing to deliver the best writing possible! The NLP algorithm is trained on millions of sentences to understand the correct format. Because of this, it may suggest the correct tense, a better synonym, or a clearer sentence structure than what you wrote. Some of the most popular grammar checkers that use NLP include Grammarly, WhiteSmoke, ProWritingAid, etc.

7. Email sorting and filtering

Email remains the most important form of professional communication. Yet all of us still receive thousands of promotional emails that we don't want to read. Fortunately, our emails are automatically divided into 3 sections: Main, Social and Promotions, which means we never have to open the Promotions section. But how does it work? Email services use natural language processing to identify the content of each email classified as text so that it can be placed in the correct section. This method isn't perfect as there are still some promotional newsletters in elementary school, but it's better than nothing. In more advanced cases, some companies also use specialized antivirus software with natural language processing to scan emails for patterns and phrases that might indicate an employee phishing attempt.


These are the most popular natural language processing apps and you've probably never heard of them! NLP is used in many other fields such as social media monitoring, translation tools, smart home devices, survey analysis, etc. You've probably used natural language processing many times, but never understood what it was all about. But now you know the incredible number of possible applications of this technology and how it improves our daily lives. If you want to learn more about this technology, you can check out several online courses.
