10 Examples of Natural Language Processing in Action

natural language programming examples

This is a NLP practice that many companies, including large telecommunications providers have put to use. NLP also enables computer-generated language close to the voice of a human. Phone calls to schedule appointments like an oil change or haircut can be automated, as evidenced by this video showing Google Assistant making a hair appointment. Things like autocorrect, autocomplete, and predictive text are so commonplace on our smartphones that we take them for granted.

After successful training on large amounts of data, the trained model will have positive outcomes with deduction. Now, however, it can translate grammatically complex sentences without any problems. This is largely thanks to NLP mixed with ‘deep learning’ capability. Deep learning is a subfield of machine learning, which helps to decipher the user’s intent, words and sentences.

  • This is where spacy has an upper hand, you can check the category of an entity through .ent_type attribute of token.
  • The process of extracting tokens from a text file/document is referred as tokenization.
  • Language Translator can be built in a few steps using Hugging face’s transformers library.
  • It is not a general-purpose NLP library, but it handles tasks assigned to it very well.

Recently, it has dominated headlines due to its ability to produce responses that far outperform what was previously commercially possible. Natural language processing ensures that AI can understand the natural human languages we speak everyday. It’s a small Windows program, less than a megabyte in size. The source code (about 25,000 sentences) is included in the download. Start with the “instructions.pdf” in the “documentation” directory and before you go ten pages you won’t just be writing “Hello, World! ” to the screen, you’ll be re-compiling the entire thing in itself (in less than three seconds on a bottom-of-the-line machine from Walmart).

A bag of words model converts the raw text into words, and it also counts the frequency for the words in the text. In summary, a bag of words is a collection of words that represent a sentence along with the word count where the order of occurrences is not relevant. In this article, we explore the basics of natural language processing (NLP) with code examples. We dive into the natural language toolkit (NLTK) library to present how it can be useful for natural language processing related-tasks.

When you send out surveys, be it to customers, employees, or any other group, you need to be able to draw actionable insights from the data you get back. Chatbots might be the first thing you think of (we’ll get to that in more detail soon). But there are actually a number of other ways NLP can be used to automate customer service.

The most commonly used Lemmatization technique is through WordNetLemmatizer from nltk library. As we already established, when performing frequency analysis, stop words need to be removed. It supports the NLP tasks like Word Embedding, text summarization and many others.

NLP Guide

We shall be using one such model bart-large-cnn in this case for text summarization. You can notice that in the extractive method, the sentences of the summary are all taken from the original text. You would have noticed that this approach is more lengthy compared to using gensim.

We also have Gmail’s Smart Compose which finishes your sentences for you as you type. Human language is filled with ambiguities that make it incredibly difficult to write software that accurately determines the intended meaning of text or voice data. A traveller wants to translate an entire webpage about local attractions from Spanish to English. The NLP translation model was built by studying huge language corpuses with paired original-translated examples. It understands mappings between word meanings and structures in both languages.

Part of Speech Tagging (PoS tagging):

For example Spatial Pixel created an natural language programming environment to turn natural language into P5.js code through OpenAI’s API. In 2021 OpenAI developed a natural language programming environment for their programming large language model called CodeX. Symbolic languages such as Wolfram Language are capable of interpreted processing of queries by sentences. The following is a list of some of the most commonly researched tasks in natural language processing.

In fact, many NLP tools struggle to interpret sarcasm, emotion, slang, context, errors, and other types of ambiguous statements. This means that NLP is mostly limited to unambiguous situations that don’t require a significant amount of interpretation. Note also that spaces are allowed in routine and variable names (like “x coord”). It’s surprising that all languages don’t support this feature; this is the 21st century, after all.

For language translation, we shall use sequence to sequence models. So, you can import the seq2seqModel through below command. These are more advanced methods and are best for summarization.

Current systems are prone to bias and incoherence, and occasionally behave erratically. Despite the challenges, machine learning engineers have many opportunities to apply NLP in ways that are ever more central to a functioning society. The all new enterprise studio that brings together traditional machine learning along with new generative AI capabilities powered by foundation models.


In NLP, such statistical methods can be applied to solve problems such as spam detection or finding bugs in software code. A word is important if it occurs many times in a document. We resolve this issue by using Inverse Document Frequency, which is high if the word is rare and low if the word is common across the corpus. The TF-IDF score of a term is the product of TF and IDF. 164 (about 5%) are trivial statements used to return boolean results, start and stop various timers, show the program’s current status, and write interesting things to the compiler’s output listing.

Now that you have understood the base of NER, let me show you how it is useful in real life. Let us start with a simple example to understand how to implement NER with nltk . It is a very useful method especially in the field of claasification problems and search egine optimizations. It is clear that the tokens of this category are not significant.

SpaCy is an open-source natural language processing Python library designed to be fast and production-ready. SpaCy focuses on providing software for production usage. Request your free demo today to see how you can streamline your business with natural language processing and MonkeyLearn. Online translators are now powerful tools thanks to Natural Language Processing.

Natural language processing (NLP) is the technique by which computers understand the human language. NLP allows you to perform a wide range of tasks such as classification, summarization, text-generation, translation and more. NLP is one of the fast-growing research domains in AI, with applications that involve tasks including translation, summarization, text generation, and sentiment analysis. Train, validate, tune and deploy generative AI, foundation models and machine learning capabilities with IBM watsonx.ai, a next-generation enterprise studio for AI builders. Build AI applications in a fraction of the time with a fraction of the data. Natural language processing (NLP) is a form of artificial intelligence (AI) that allows computers to understand human language, whether it be written, spoken, or even scribbled.

Natural language Processing (NLP) is a subfield of artificial intelligence, in which its depth involves the interactions between computers and humans. In summary, natural language processing aims to teach computers the ability to understand and converse in human tongues using cutting-edge AI. Through massive data and state-of-the-art modeling, it powers innovations across domains to bridge the gaps natural language programming examples between people and technology. As NLP systems become even more sophisticated, we may see computers gain increasingly intelligent comprehension of written, spoken and conversational language similar to humans. Their applications have the potential to automate tasks, expand access to information and create entirely new ways of interacting with computer systems through familiar natural language.

However, this process can take much time, and it requires manual effort. In order to streamline certain areas of your business and reduce labor-intensive manual work, it’s essential to harness the power of artificial intelligence. People go to social media to communicate, be it to read and listen or to speak and be heard. As a company or brand you can learn a lot about how your customer feels by what they comment, post about or listen to. The applications above represent only a fraction of current NLP use cases.

It can sort through large amounts of unstructured data to give you insights within seconds. Similarly, support ticket routing, or making sure the right query gets to the right team, can also be automated. This is done by using NLP to understand what the customer needs based on the language they are using.

Autocomplete and predictive text are similar to search engines in that they predict things to say based on what you type, finishing the word or suggesting a relevant one. And autocorrect will sometimes even change words so that the overall message makes more sense. Predictive text will customize itself to your personal language quirks the longer you use it. This makes for fun experiments where individuals will share entire sentences made up entirely of predictive text on their phones. The results are surprisingly personal and enlightening; they’ve even been highlighted by several media outlets.

Implementing NLP Tasks

Customer service costs businesses a great deal in both time and money, especially during growth periods. Smart assistants, which were once in the realm of science fiction, are now commonplace. If you’re not adopting NLP technology, you’re probably missing out on ways to automize or gain business insights. This could in turn lead to you missing out on sales and growth. Conversational Commerce – Enabling shopping conversations through voice assistants or chat to recommend products, process payments and provide support. The simpletransformers library has ClassificationModel which is especially designed for text classification problems.

In the sentence above, we can see that there are two “can” words, but both of them have different meanings. Here the first “can” word is used https://chat.openai.com/ for question formation. The second “can” word at the end of the sentence is used to represent a container that holds food or liquid.

As shown in the graph above, the most frequent words display in larger fonts. Notice that we still have many words that are not very useful in the analysis of our text file sample, such as “and,” “but,” “so,” and others. Next, we can see the entire text of our data is represented as words and also notice that the total number of words here is 144. By tokenizing the text with word_tokenize( ), we can get the text as words. For various data processing cases in NLP, we need to import some libraries.

Sentiment Analysis – Analyzing customer reviews and social media to determine overall opinions and feelings toward brands, products and more. Virtual Assistants – Siri, Alexa, Google Assistant and other AI helpers use NLP to comprehend speech, answer queries and carry out tasks through natural conversations. Language support (programming and human), latency and price… and last but not least, quality.

As AI-powered devices and services become increasingly more intertwined with our daily lives and world, so too does the impact that NLP has on ensuring a seamless human-computer experience. Natural Language Processing started in 1950 When Alan Mathison Turing published an article in the name Computing Machinery and Intelligence. It talks about automatic interpretation and generation of natural language. As the technology evolved, different approaches have come to deal with NLP tasks. It is the branch of Artificial Intelligence that gives the ability to machine understand and process human languages. Human languages can be in the form of text or audio format.

The proposed test includes a task that involves the automated interpretation and generation of natural language. None of this would be possible without NLP which allows chatbots to listen to what customers are telling them and provide an appropriate response. This response is further enhanced when sentiment analysis and intent classification tools are used. The overarching goal is creating computational systems that can understand, interpret and generate human language to the same degree as people can converse with each other. When successful, NLP will make interfaces between humans and technology as seamless as talking with another person.

You can categorize the tokens depending on the POS tags. Below example demonstrates how to print all the NOUNS in robot_doc. See below code to understand how to work with text files.

Chunking takes PoS tags as input and provides chunks as output. Chunking literally means a group of words, which breaks simple text into phrases that are more meaningful than individual words. In the graph above, notice that a period “.” is used nine times in our text. Analytically speaking, punctuation marks are not that important for natural language processing. Therefore, in the next step, we will be removing such punctuation marks.

In spaCy, the POS tags are present in the attribute of Token object. You can access the POS tag of particular token theough the token.pos_ attribute. You see that the keywords are gangtok , sikkkim,Indian and so on. Let us see an example of how to implement stemming using nltk supported PorterStemmer().

These are some of the basics for the exciting field of natural language processing (NLP). We hope you enjoyed reading this article and learned something new. Any suggestions or feedback is crucial to continue to improve. In English and many other languages, a single word can take multiple forms depending upon context used. For instance, the verb “study” can take many forms like “studies,” “studying,” “studied,” and others, depending on its context.

In this case, we define a noun phrase by an optional determiner followed by adjectives and nouns. Then we can define other rules to extract some other phrases. Next, we are going to use RegexpParser( ) to parse the grammar.

Let us look at more methods to understand the text data. The words which occur more frequently in the text often have the key to the core of the text. So, we shall try to store all tokens with their frequencies for the same purpose. You can foun additiona information about ai customer service and artificial intelligence and NLP. I’ll show lemmatization using nltk and spacy in this article.

The transformers library of hugging face provides a very easy and advanced method to implement this function. Generative text summarization methods overcome this shortcoming. The concept is based on capturing the meaning of the text and generating entitrely new sentences to best represent them in the summary. Next , you can find the frequency of each token in keywords_list using Counter.

Afterward, we will discuss the basics of other Natural Language Processing libraries and other essential methods for NLP, along with their respective coding sample implementations in Python. As computing power increases, NLP systems also incorporate more advanced techniques like contextual word embeddings, attention mechanisms and transfer learning between tasks. The sophistication of these models is what allows NLP to intelligently process human input.

First, we will see an overview of our calculations and formulas, and then we will implement it in Python. We can use Wordnet to find meanings of words, synonyms, antonyms, and many other words. Named entity recognition can automatically scan entire articles and pull out some fundamental entities like people, organizations, places, date, time, money, and GPE discussed in them. In the code snippet below, we show that all the words truncate to their stem words.

That is why it generates results faster, but it is less accurate than lemmatization. NLP is special in that it has the capability to make sense of these reams of unstructured information. Tools like keyword extractors, sentiment analysis, and intent classifiers, to name a few, are particularly useful.

Pragmatic analysis deals with overall communication and interpretation of language. It deals with deriving meaningful use of language in various situations. They are effectively trained by their owner and, like other applications of NLP, learn from experience in order to provide better, more tailored assistance. Search autocomplete is a good example of NLP at work in a search engine. This function predicts what you might be searching for, so you can simply click on it and save yourself the hassle of typing it out. Natural Language Processing (NLP) is at work all around us, making our lives easier at every turn, yet we don’t often think about it.

Dependency Parsing is the method of analyzing the relationship/ dependency between different words of a sentence. In a sentence, the words have a relationship with each other. The one word in a sentence which is independent of others, is called as Head /Root word.

Here, I shall guide you on implementing generative text summarization using Hugging face . You can access the sentences in a doc through doc.sents. You can iterate through each token of sentence , select the keyword values and store them in a dictionary score. For that, find the highest frequency using .most_common method . Then apply normalization formula to the all keyword frequencies in the dictionary. Next , you know that extractive summarization is based on identifying the significant words.

In this piece, we’ll go into more depth on what NLP is, take you through a number of natural language processing examples, and show you how you can apply these within your business. One of the tell-tale signs of cheating on your Spanish homework is that grammatically, it’s a mess. Many languages don’t allow for straight translation and have different orders for sentence structure, which translation services used to overlook.

As shown above, all the punctuation marks from our text are excluded. Notice that the most used words are punctuation marks and stopwords. We will have to remove such words to analyze the actual text. In the example above, we can see the entire text of our data is represented as sentences and also notice that the total number of sentences here is 9. By tokenizing the text with sent_tokenize( ), we can get the text as sentences.

The latest AI models are unlocking these areas to analyze the meanings of input text and generate meaningful, expressive output. We don’t regularly think about the intricacies of our own languages. It’s an intuitive behavior used to convey information and meaning with semantic cues such as words, signs, or images. It’s been said that language is easier to learn and comes more Chat PG naturally in adolescence because it’s a repeatable, trained behavior—much like walking. That’s why machine learning and artificial intelligence (AI) are gaining attention and momentum, with greater human dependency on computing systems to communicate and perform tasks. And as AI and augmented analytics get more sophisticated, so will Natural Language Processing (NLP).

When we tokenize words, an interpreter considers these input words as different words even though their underlying meaning is the same. Moreover, as we know that NLP is about analyzing the meaning of content, to resolve this problem, we use stemming. For this tutorial, we are going to focus more on the NLTK library.

As technology progresses, new innovations will continue emerging to reshape outdated interfaces between humans and machines. You have seen the various uses of NLP techniques in this article. I hope you can now efficiently perform these tasks on any real dataset.

This technique of generating new sentences relevant to context is called Text Generation. You can always modify the arguments according to the neccesity of the problem. You can view the current values of arguments through model.args method. The parameters min_length and max_length allow you to control the length of summary as per needs. Now, you need to normalize the frequency of all keywords.
