What is Natural Language Processing? Introduction to NLP

The raw text data often referred to as text corpus has a lot of noise. There are punctuation, suffices and stop words that do not give us any information. Text Processing involves preparing the text corpus to make it more usable for NLP tasks.

Summarizing documents and generating reports is yet another example of an impressive use case for AI. We can generate reports on the fly using natural language processing tools trained in parsing and generating coherent text documents. There are multiple real-world applications of natural language processing. Since the program always tries to find a content-wise synonym to complete the task, the results are much more accurate and meaningful.

Part of Speech Tagging

AutoTag uses latent dirichlet allocation to identify relevant keywords from the text. Identify the type of entity extracted, such as it being a person, place, or organization using Named Entity Recognition. Watch this demo to discover how businesses deliver real-world results with AI. For example, the words “running”, “runs” and “ran” are all forms of the word “run”, so “run” is the lemma of all the previous words.

Automatic summarization can be particularly useful for data entry, where relevant information is extracted from a product description, for example, and automatically entered into a database. Predictive text, autocorrect, and autocomplete have become so accurate in word processing programs, like MS Word and Google Docs, that they can make us feel like we need to go back to grammar school. Every time you type a text on your smartphone, you see NLP in action. You often only have to type a few letters of a word, and the texting app will suggest the correct one for you.

They form the base layer of information that our mid-level functions draw on. Mid-level text analytics functions involve extracting the real content of a document of text. This means who is speaking, what they are saying, and what All About NLP they are talking about. But how do you teach a machine learning algorithm what a word looks like? And what if you’re not working with English-language documents? Logographic languages like Mandarin Chinese have no whitespace.

Vectorizing is the process of encoding text as integers to create feature vectors so that machine learning algorithms can understand language. Rather than building all of your NLP tools from scratch, NLTK provides all common NLP tasks so you can jump right in. Chinese follows rules and patterns just like English, and we can train a machine learning model to identify and understand them. The Cloud NLP API is used to improve the capabilities of the application using natural language processing technology. It allows you to carry various natural language processing functions like sentiment analysis and language detection. Natural Language Processing APIs allow developers to integrate human-to-machine communications and complete several useful tasks such as speech recognition, chatbots, spelling correction, sentiment analysis, etc.

The fact that clinical documentation can be improved means that patients can be better understood and benefited through better healthcare. The goal should be to optimize their experience, and several organizations are already working on this. Powered by IBM Watson NLP technology, LegalMation developed a platform to automate routine litigation tasks and help legal teams save time, drive down costs and shift strategic focus. An inventor at IBM developed a cognitive assistant that works like a personalized search engine by learning all about you and then remind you of a name, a song, or anything you can’t remember the moment you need it to. Adjusting the content of the Website pages to specific User’s preferences and optimizing the websites website experience to the each User’s individual needs.

But today’s programs, armed with machine learning and deep learning algorithms, go beyond picking the right line in reply, and help with many text and speech processing problems. Still, all of these methods coexist today, each making sense in certain use cases. Natural language processing or NLP is a branch of Artificial Intelligence that gives machines the ability to understand natural human speech. Using linguistics, statistics, and machine learning, computers not only derive meaning from what’s said or written, they can also catch contextual nuances and a person’s intent and sentiment in the same way humans do. One of the top use cases of natural language processing is translation. The first NLP-based translation machine was presented in the 1950s by Georgetown and IBM, which was able to automatically translate 60 Russian sentences to English.

Common Examples of NLP

Case Grammar was developed by Linguist Charles J. Fillmore in the year 1968. Case Grammar uses languages such as English to express the relationship between nouns and verbs by using the preposition. In 1957, Chomsky also introduced the idea of Generative Grammar, which is rule based descriptions of syntactic structures. Legal firms will benefit when pages and pages of legal documents, stenographer notes, testimonies, and/or police reports can be translated to data and easily summarized. Software applications using NLP and AI are expected to be a $5.4 billion market by 2025. The possibilities for both big data, and the industries it powers, are almost endless.

When we write, we often misspell or abbreviate words, or omit punctuation. When we speak, we have regional accents, and we mumble, stutter and borrow terms from other languages. The analytics vendor and open source tool have already developed integrations that combine self-service BI and semantic modeling,… NLP was largely rules-based, using handcrafted rules developed by linguists to determine how computers would process language. Natural language processing has its roots in this decade, when Alan Turing developed the Turing Test to determine whether or not a computer is truly intelligent.

State-of-the-Art Machine Learning Methods – Large Language Models and Transformers Architecture

I am a data lover and I love to extract and understand the hidden patterns in the data. I want to learn and grow in the field of Machine Learning and Data Science. A different type of grammar is Dependency Grammar which states that words of a sentence are dependent upon other words of the sentence. For example, in the previous sentence “barking dog” was mentioned and the dog was modified by barking as the dependency adjective modifier exists between the two.

Tokenization involves breaking a text document into pieces that a machine can understand, such as words. Now, you’re probably pretty good at figuring out what’s a word and what’s gibberish. The Translation API by SYSTRAN is used to translate the text from the source language to the target language. You can use its NLP APIs for language detection, text segmentation, named entity recognition, tokenization, and many other tasks.

GluonNLP – A deep learning toolkit for NLP, built on MXNet/Gluon, for research prototyping and industrial deployment of state-of-the-art models on a wide range of NLP tasks. NLP-Overview is an up-to-date overview of deep learning techniques applied to NLP, including theory, implementations, applications, and state-of-the-art results. The goal is now to improve reading comprehension, word sense disambiguation and inference. Beginning to display what humans call “common sense” is improving as the models capture more basic details about the world. Some AI scientists have analyzed some large blocks of text that are easy to find on the internet to create elaborate statistical models that can understand how context shifts meanings.

Indeed, programmers used punch cards to communicate with the first computers 70 years ago. This manual and arduous process was understood by a relatively small number of people. Now you can say, “Alexa, I like this song,” and a device playing music in your home will lower the volume and reply, “OK. Then it adapts its algorithm to play that song – and others like it – the next time you listen to that music station. As a human, you may speak and write in English, Spanish or Chinese.
