Natural Language Processing NLP Examples

It is primarily concerned with giving computers the ability to support and manipulate speech. It involves processing natural language datasets, such as text corpora or speech corpora, using either rule-based or probabilistic (i.e. statistical and, most recently, neural network-based) machine learning approaches. The goal is a computer capable of “understanding” the contents of documents, including the contextual nuances of the language within them. The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves. NLP combines computational linguistics—rule-based modeling of human language—with statistical, machine learning, and deep learning models. Together, these technologies enable computers to process human language in the form of text or voice data and to ‘understand’ its full meaning, complete with the speaker or writer’s intent and sentiment.

NLP gives computers the ability to understand spoken words and text the same as humans do. The model analyzes the parts of speech to figure out what exactly the sentence is talking about. This article will look at how natural language processing functions in AI. Overall, NLP is a powerful technology that is transforming the way businesses operate.

Language Identification

By counting the one-, two- and three-letter sequences in a text (unigrams, bigrams and trigrams), a language can be identified from a short sequence of a few sentences only. A slightly more sophisticated technique for language identification is to assemble a list of N-grams, which are sequences of characters which have a characteristic frequency in each language. For example, the combination ch is common in English, Dutch, Spanish, German, French, and other languages. Marketing is the most important practice a business commonly works upon to list them among the successful businesses. Also, without marketing, circulating the ideology of business with the globe is a bit challenging.

• Three tools used commonly for natural language processing include Natural Language Toolkit (NLTK), Gensim and Intel natural language processing Architect.
• Conversation analytics can help energy and utilities companies enhance customer experience and remain compliant to industry regulations.
• Phenotyping is the process of analyzing a patient’s physical or biochemical characteristics (phenotype) by relying on only genetic data from DNA sequencing or genotyping.
• The right interaction with the audience is the driving force behind the success of any business.

Training done with labeled data is called supervised learning and it has a great fit for most common classification problems. Some of the popular algorithms for NLP tasks are Decision Trees, Naive Bayes, Support-Vector Machine, Conditional Random Field, etc. After training the model, data scientists test and validate it to make sure it gives the most accurate predictions and is ready for running in real life. Though often, AI developers use pretrained language models created for specific problems. NLP is a subset of AI that helps machines understand human intentions or human language.

It is the process of producing meaningful phrases and sentences in the form of natural language from some internal representation. Information extraction is one of the most important applications of NLP. It is used for extracting structured information from unstructured or semi-structured machine-readable documents.

Expert.ai’s NLP platform gives publishers and content producers the power to automate important categorization and metadata information through the use of tagging, creating a more engaging and personalized experience for readers. Publishers and information service providers can suggest content to ensure that users see the topics, documents or products that are most relevant to them. Here, NLP breaks language down into parts of speech, word stems and other linguistic features. Natural language understanding (NLU) allows machines to understand language, and natural language generation (NLG) gives machines the ability to “speak.”Ideally, this provides the desired response. First, the capability of interacting with an AI using human language—the way we would naturally speak or write—isn’t new.

Chatbots do all this by recognizing the intent of a user’s query and then presenting the most appropriate response. They use high-accuracy algorithms that are powered by NLP and semantics. A chatbot system uses AI technology to engage with a user in natural language—the way a person would communicate if speaking or writing—via messaging applications, websites or mobile apps.

• Latent Dirichlet Allocation performed in Python across a scientific paper dataset.
• Very common words like ‘in’, ‘is’, and ‘an’ are often used as stop words since they don’t add a lot of meaning to a text in and of themselves.
• Although, compared to Uber’s bot, this bot functions more like a virtual assistant.
• NLP combines rule-based modeling of human language called computational linguistics, with other models such as statistical models, Machine Learning, and deep learning.

This technology even extends to languages like Russian and Chinese, which are traditionally more difficult to translate due to their different alphabet structure and use of characters instead of letters. To better understand the applications of this technology for businesses, let’s look at an NLP example. Sentiment analysis (also known as opinion mining) is an NLP strategy that can determine whether the meaning behind data is positive, negative, or neutral. For instance, if an unhappy client sends an email which mentions the terms “error” and “not worth the price”, then their opinion would be automatically tagged as one with negative sentiment. Autocorrect can even change words based on typos so that the overall sentence’s meaning makes sense.

Data analysis

These functionalities have the ability to learn and change based on your behavior. For example, over time predictive text will learn your personal jargon and customize itself. It might feel like your thought is being finished before you get the chance to finish typing. Natural language processing (NLP) is a branch of Artificial Intelligence or AI, that falls under the umbrella of computer vision.

He advised enterprises on their technology decisions at McKinsey & Company and Altman Solon for more than a decade. He led technology strategy and procurement of a telco while reporting to the CEO. He has also led commercial growth of deep tech company Hypatos that reached a 7 digit annual recurring revenue and a 9 digit valuation from 0 within 2 years. Cem’s work in Hypatos was covered by leading technology publications like TechCrunch and Business Insider.

By collecting the plus and minus based on the reviews, it helps companies to gain insight of products’ or services’ best qualities and the features most liked/disliked by the users. Through social media reviews, ratings, and feedback, it becomes easier for organizations to offer results users are asking for. By integrating NLP into the systems helps in monitoring and responding to the feedback more easily and effectively. Predictive analysis and autocomplete works like search engines predicting things based on the user search typing and then finishing the search with suggested words. Many times, an autocorrect can also change the overall message creating more sense to the statement.

“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. Conversation analytics provides business insights that lead to better CX and business outcomes for technology companies. Take your omnichannel retail and eccommerce sales and customer experience to new heights with conversation analytics for deep customer insights. Reveal patterns and insights at scale to understand customers, better meet their needs and expectations, and drive customer experience excellence.

Here, NLP identifies the phrase closest to your typo and automatically changes your wrong expression to the correct one. NLG pertains to a computer’s ability to create its own communication, whereas NLU is about a system’s ability to understand the jargon, mispronunciations, misspellings, and other language variants. In case you need any help with development, installation, integration, up-gradation and customization of your Business Solutions. We have expertise in Deep learning, Computer Vision, Predictive learning, CNN, HOG and NLP. Converse Smartly® is an advanced speech recognition application for the web developed by Folio3.

In-store bots act as shopping assistants, suggest products to customers, help customers locate the desired product, and provide information about upcoming sales or promotions. NLP can be used to convert spoken language into text, allowing for voice-based interfaces and dictation. This is used in applications such as virtual assistants, speech-to-text transcription services and other voice-based applications.

With named entity recognition, you can find the named entities in your texts and also determine what kind of named entity they are. The Porter stemming algorithm dates from 1979, so it’s a little on the older side. The Snowball stemmer, which is also called Porter2, is an improvement on the original and is also available through NLTK, so you can use that one in your own projects. It’s also worth noting that the purpose of the Porter stemmer is not to produce complete words but to find variant forms of a word. The predictive text uses NLP to predict what word users will type next based on what they have typed in their message. This reduces the number of keystrokes needed for users to complete their messages and improves their user experience by increasing the speed at which they can type and send messages.

Even English, with its relatively simple writing system based on the Roman alphabet, utilizes logographic symbols which include Arabic numerals, Currency symbols (S, £), and other special symbols. Individual words are analyzed into their components, and nonword tokens such as punctuations are separated from the words. Here, we can see two words kings and kings where one is singular and other is plural.
