Natural Language Processing With Python’s NLTK Package

IBM’s Global Adoption Index cited that almost half of businesses surveyed globally are using some kind of application powered by NLP.

If you’re analyzing a single text, this can help you see which words show up near each other. If you’re analyzing a corpus of texts that is organized chronologically, it can help you see which words were being used more or less over a period of time. If you’d like to learn how to get other texts to analyze, then you can check out Chapter 3 of Natural Language Processing with Python – Analyzing Text with the Natural Language Toolkit. Chunking makes use of POS tags to group words and apply chunk tags to those groups. Chunks don’t overlap, so one instance of a word can be in only one chunk at a time. For example, if you were to look up the word “blending” in a dictionary, then you’d need to look at the entry for “blend,” but you would find “blending” listed in that entry.

Instead of needing to use specific predefined language, a user could interact with a voice assistant like Siri on their phone using their regular diction, and their voice assistant will still be able to understand them. Natural Language Processing has created the foundations for improving the functionalities of chatbots. One of the popular examples of such chatbots is the Stitch Fix bot, which offers personalized fashion advice according to the style preferences of the user. The rise of human civilization can be attributed to different aspects, including knowledge and innovation.

OpenAI’s GPT-2 is an impressive language model showcasing autonomous learning skills. It can generate coherent paragraphs and achieve promising results in various tasks, making it a highly competitive model. ChatGPT-3 is a transformer-based NLP model renowned for its diverse capabilities, including translations, question answering, and more. With recent advancements, it excels at writing news articles and generating code. What sets ChatGPT-3 apart is its ability to perform downstream tasks without needing fine-tuning, effectively managing statistical dependencies between different words. The model’s remarkable performance is attributed to its extensive training on over 175 billion parameters, drawing from a colossal 45 TB text corpus sourced from various internet sources.

Natural language processing (NLP) is a branch of artificial intelligence (AI) that enables machines to understand human language. The main intention of NLP is to build systems that are able to make sense of text and then automatically execute tasks like spell-check, text translation, topic classification, etc. Companies today use NLP in artificial intelligence to gain insights from data and automate routine tasks. NLP has evolved since the 1950s, when language was parsed through hard-coded rules and reliance on a subset of language. The 1990s introduced statistical methods for NLP that enabled computers to be trained on the data (to learn the structure of language) rather than be told the structure through rules.

Examples of Natural Language Processing in Action

Search engines leverage NLP to suggest relevant results based on previous search history behavior and user intent. 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. However, it has come a long way, and without it many things, such as large-scale efficient analysis, wouldn’t be possible. One of the algorithms it implements is called Semi-structured Statement Extraction. We can use it to search the parse tree for simple statements where the subject is “London” and the verb is a form of “be”.

Conversation analytics provides business insights that lead to better patient outcomes for the professionals in the healthcare industry. Use customer insights to power product-market fit and drive loyalty. Improve quality and safety, identify competitive threats, and evaluate innovation opportunities. Likewise, NLP is useful for the same reasons as when a person interacts with a generative AI chatbot or AI voice assistant.

For years, trying to translate a sentence from one language to another would consistently return confusing and/or offensively incorrect results. This was so prevalent that many questioned if it would ever be possible to accurately translate text. NLP customer service implementations are being valued more and more by organizations.

Data Structures and Algorithms

Being able to create a shorter summary of longer text can be extremely useful given the time we have available and the massive amount of data we deal with daily. RoBERTa, short for the Robustly Optimized BERT pre-training approach, represents an optimized method for pre-training self-supervised NLP systems. Built on BERT’s language masking strategy, RoBERTa learns and predicts intentionally hidden text sections. As a pre-trained model, RoBERTa excels in all tasks evaluated by the General Language Understanding Evaluation (GLUE) benchmark.

That’s why grammar and spell checkers are a very important tool for any professional writer. They can not only correct grammar and check spellings but also suggest better synonyms and improve the overall readability of your content. And guess what, they utilize natural language processing to provide the best possible piece of writing! The NLP algorithm is trained on millions of sentences to understand the correct format. That is why it can suggest the correct verb tense, a better synonym, or a clearer sentence structure than what you have written.

You would think that writing a spellchecker is as simple as assembling a list of all allowed words in a language, but the problem is far more complex than that. Nowadays the more sophisticated spellcheckers use neural networks to check that the correct homonym is used. Also, for languages with more complicated morphologies than English, spellchecking can become very computationally intensive. Natural language processing can be used for topic modelling, where a corpus of unstructured text can be converted to a set of topics.

• The major downside of rules-based approaches is that they don’t scale to more complex language.
• Transformers are able to represent the grammar of natural language in an extremely deep and sophisticated way and have improved performance of document classification, text generation and question answering systems.
• The study of natural language processing has advanced significantly.
• Many of the unsupported languages are languages with many speakers but non-official status, such as the many spoken varieties of Arabic.

The first chatbot was created in 1966, thereby validating the extensive history of technological evolution of chatbots. Just like any new technology, it is difficult to measure the potential of NLP for good without exploring natural language programming examples 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.

It defines a way in which computers and languages interact with each other. Its main aim is to understand human speech, process it, and then generate the output as the same form of input. It can do this with the help of various artificial intelligence, machine learning, and deep learning models.

NLP is a subset of AI that helps machines understand human intentions or human language. Some examples are chatbots and voice assistants like Siri and Alexa. Rules-based approaches often imitate how humans parse sentences down to their fundamental parts. A sentence is first tokenized down to its unique words and symbols (such as a period indicating the end of a sentence). Preprocessing, such as stemming, then reduces a word to its stem or base form (removing suffixes like -ing or -ly). The resulting tokens are parsed to understand the structure of the sentence.

Many languages don’t allow for straight translation and have different orders for sentence structure, which translation services used to overlook. With NLP, online translators can translate languages more accurately and present grammatically-correct results. This is infinitely helpful when trying to communicate with someone in another language.

It simply composes sentences by simulating human speeches by being unbiased. There are calls that are recorded for training purposes but in actuality, they are recorded to the database for an NLP system to learn and improve services in the future. This is also one of the natural language processing examples that are being used by organizations from the last many years.

But at the same time, it is difficult to track queries for every customer. These chatbots are the outcome of natural language processing in AI (Artificial Intelligence). These solutions can ensure that the service providers relate to their customers and provide solutions to their queries instantly. Natural Language Processing is becoming increasingly important for businesses to understand and respond to customers.

Gmail, for instance, uses NLP to create “smart replies” that can be used to automatically generate a response. By extracting meaning from written text, NLP allows businesses to gain insights about their customers and respond accordingly. “According to the FBI, the total cost of insurance fraud (non-health insurance) is estimated to be more than $40 billion per year. Insurance fraud affects both insurers and customers, who end up paying higher premiums to cover the cost of fraudulent claims.

RNNs have been around for some time, but newer models, like the long–short-term memory (LSTM) model, are also widely used for text processing and generation. Statistical methods for NLP are defined as those that involve statistics and, in particular, the acquisition of probabilities from a data set in an automated way (i.e., they’re learned). This method obviously differs from the previous approach, where linguists construct rules to parse and understand language. In the statistical approach, instead of the manual construction of rules, a model is automatically constructed from a corpus of training data representing the language to be modeled. As can be seen, NLP uses a wide range of programming languages and libraries to address the challenges of understanding and processing human language. The choice of language and library depends on factors such as the complexity of the task, data scale, performance requirements, and personal preference.

However, there is still a lot of work to be done to improve the coverage of the world’s languages. Facebook estimates that more than 20% of the world’s population is still not currently covered by commercial translation technology. In general coverage is very good for major world languages, with some outliers (notably Yue and Wu Chinese, sometimes known as Cantonese and Shanghainese). Post your job with us and attract candidates who are as passionate about natural language processing. “The decisions made by these systems can influence user beliefs and preferences, which in turn affect the feedback the learning system receives — thus creating a feedback loop,” researchers for Deep Mind wrote in a 2019 study.

In many applications, NLP software is used to interpret and understand human language, while ML is used to detect patterns and anomalies and learn from analyzing data. With an ever-growing number of use cases, NLP, ML and AI are ubiquitous in modern life, and most people have encountered these technologies in action without even being aware of it. The main benefit of NLP is that it improves the way humans and computers communicate with each other.

Autocorrect relies on NLP and machine learning to detect errors and automatically correct them. “One of the features that use Natural Language Processing (NLP) is the Autocorrect function. This feature works on every smartphone keyboard regardless of the brand. Natural language processing plays a vital part in technology and the way humans interact with it. Though it has its challenges, NLP is expected to become more accurate with more sophisticated models, more accessible and more relevant in numerous industries.

Insurers can use NLP to try to mitigate the high cost of fraud, lower their claims payouts and decrease premiums for their customers. NLP models can be used to analyze past fraudulent claims in order to detect claims with similar attributes and flag them. On the other hand, NLP can take in more factors, such as previous search data and context. Conversation analytics provides business insights that lead to better CX and business outcomes for technology companies.

While the terms AI and NLP might conjure images of futuristic robots, there are already basic examples of NLP at work in our daily lives.

• Social listening powered by AI tasks like NLP enables you to analyze thousands of social conversations in seconds to get the business intelligence you need.
• Every day, humans exchange countless words with other humans to get all kinds of things accomplished.
• These are the most common natural language processing examples that you are likely to encounter in your day to day and the most useful for your customer service teams.
• But over time our NLP models will continue to get better at parsing text in a sensible way.

NLP algorithms generate summaries by paraphrasing the content so it differs from the original text but contains all essential information. It involves sentence scoring, clustering, and content and sentence position analysis. NLP with programming languages such as Python can help us to translate the text into different languages. These machine translations can help us to communicate with people living in different countries. By bringing NLP into the workplace, companies can analyze data to find what’s relevant amidst the chaos, and gain valuable insights that help automate tasks and drive business decisions.

NLP can be simply integrated into an app or a website for a user-friendly experience. The NLP integrated features like autocomplete, autocorrection, spell checkers located in search bars can provide users a way to find & get information in a click. In any of the cases, a computer- digital technology that can identify words, phrases, or responses using context related hints.

The different examples of natural language processing in everyday lives of people also include smart virtual assistants. You can notice that smart assistants such as Google Assistant, Siri, and Alexa have gained formidable improvements in popularity. The voice assistants are the best NLP examples, which work through speech-to-text conversion and intent classification for classifying inputs as action or question.
