A subfield of artificial intelligence and linguistics, NLP provides the advanced language analysis and processing that allows computers to make this unstructured human language data readable by machines. It can use many different methods to accomplish this, from tokenization, lemmatization, machine translation and natural language understanding. Natural language generation is another subset of natural language processing. While natural language understanding focuses on computer reading comprehension, natural language generation enables computers to write.

Natural language processing works by taking unstructured data and converting it into a structured data format. For example, the suffix -ed on a word, like called, indicates past tense, but it has the same base infinitive (to call) as the present tense verb calling. NLP is a branch of artificial intelligence (AI) that bridges human and machine language to enable more natural human-to-computer communication. When information goes into a typical NLP system, it goes through various phases, including lexical analysis, discourse integration, pragmatic analysis, parsing, and semantic analysis. It is also applied in text classification, document matching, machine translation, named entity recognition, search autocorrect and autocomplete, etc.

It takes into account the broader context and prior knowledge to comprehend the meaning behind the ambiguous or indirect language. Language generation is used for automated content, personalized suggestions, virtual assistants, and more. Systems can improve user experience and communication by using NLP’s language generation.

How does natural language understanding work?

NLP is a subfield of Artificial Intelligence that focuses on the interaction between computers and humans in natural language. It involves techniques for analyzing, understanding, and generating human language. NLP enables machines to read, understand, and respond to natural language input. NLP takes input text in the form of natural language, converts it into a computer language, processes it, and returns the information as a response in a natural language. NLU converts input text or speech into structured data and helps extract facts from this input data.

The future of language processing and understanding with artificial intelligence is brimming with possibilities. Advances in Natural Language Processing (NLP) and Natural Language Understanding (NLU) are transforming how machines engage with human language. Enhanced NLP algorithms are facilitating seamless interactions with chatbots and virtual assistants, while improved NLU capabilities enable voice assistants to better comprehend customer inquiries. NLU is the ability of a machine to understand and process the meaning of speech or text presented in a natural language, that is, the capability to make sense of natural language.

While syntax focuses on the rules governing language structure, semantics delves into the meaning behind words and sentences. In the realm of artificial intelligence, NLU and NLP bring these concepts to life. Sometimes you may have too many lines of text data, and you have time scarcity to handle all that data. NLG is used to generate a semantic understanding of the original document and create a summary through text abstraction or text extraction. In text extraction, pieces of text are extracted from the original document and put together into a shorter version while maintaining the same information content.

Semantic Analysis

NLP’s dual approach blends human-crafted rules with data-driven techniques to comprehend and generate text effectively. While both understand human language, NLU communicates with untrained individuals to learn and understand their intent. In addition to understanding words and interpreting meaning, NLU is programmed to understand meaning, despite common human errors, such as mispronunciations or transposed letters and words. NLP attempts to analyze and understand the text of a given document, and NLU makes it possible to carry out a dialogue with a computer using natural language. Have you ever wondered how Alexa, ChatGPT, or a customer care chatbot can understand your spoken or written comment and respond appropriately?

However, NLG can be used with NLP to produce humanlike text in a way that emulates a human writer. This is done by identifying the main topic of a document and then using NLP to determine the most appropriate way to write the document in the user’s native language. When an unfortunate incident occurs, customers file a claim to seek compensation.

In this section, we will introduce the top 10 use cases, of which five are related to pure NLP capabilities and the remaining five need for NLU to assist computers in efficiently automating these use cases. Figure 4 depicts our sample of 5 use cases in which businesses should favor NLP over NLU or vice versa. NLU skills are necessary, though, if users’ sentiments vary significantly or if AI models are exposed to explaining the same concept in a variety of ways. Let’s illustrate this example by using a famous NLP model called Google Translate.

Each plays a unique role at various stages of a conversation between a human and a machine. DST is essential at this stage of the dialogue system and is responsible for multi-turn conversations. Then, a dialogue policy determines what next step the dialogue system makes based on the current state.

NLP focuses on processing the text in a literal sense, like what was said. Conversely, NLU focuses on extracting the context and intent, or in other words, what was meant. From the computer’s point of view, any natural language is a free form text. That means there are no set keywords at set positions when providing an input.

On the other hand, NLU delves deeper into the semantic understanding and contextual interpretation of language. It goes beyond the structural aspects and aims to comprehend the meaning, intent, and nuances behind human communication. NLU tasks involve entity recognition, intent recognition, sentiment analysis, and contextual understanding. By leveraging machine learning and semantic analysis techniques, NLU enables machines to grasp the intricacies of human language.

NLP techniques such as tokenization, stemming, and parsing are employed to break down sentences into their constituent parts, like words and phrases. This process enables the extraction of valuable information from the text and allows for a more in-depth analysis of linguistic patterns. For example, NLP can identify noun phrases, verb phrases, and other grammatical structures in sentences. Natural Language Understanding (NLU), a subset of Natural Language Processing (NLP), employs semantic analysis to derive meaning from textual content.

NLP can study language and speech to do many things, but it can’t always understand what someone intends to say. NLU enables computers to understand what someone meant, even if they didn’t say it perfectly. Together, NLU and natural language generation enable NLP to function effectively, providing a comprehensive language processing solution.

To interpret a text and understand its meaning, NLU must first learn its context, semantics, sentiment, intent, and syntax. Semantics and syntax are of utmost significance in helping check the grammar and meaning of a text, respectively. Though NLU understands unstructured data, part of its core function is to convert text into a structured data set that a machine can more easily consume.

NLU is at the forefront of advancements in AI and has the potential to revolutionize areas such as customer service, personal assistants, content analysis, and more. NLP has the potential to revolutionize industries such as healthcare, customer service, information retrieval, and language education, among others.

Artificial intelligence is critical to a machine’s ability to learn and process natural language. So, when building any program that works on your language data, it’s important to choose the right AI approach.

Difference Between NLP And NLU

NLU aims to understand the intent, context, and emotions behind the words used in a text. It involves techniques like sentiment analysis, named entity recognition, and coreference resolution. NLP, with its focus on language structure and statistical patterns, enables machines to analyze, manipulate, and generate human language.

This is useful for consumer products or device features, such as voice assistants and speech to text. Most of the time financial consultants try to understand what customers were looking for since customers do not use the technical lingo of investment. Since customers’ input is not standardized, chatbots need powerful NLU capabilities to understand customers. For instance, the address of the home a customer wants to cover has an impact on the underwriting process since it has a relationship with burglary risk. NLP-driven machines can automatically extract data from questionnaire forms, and risk can be calculated seamlessly.

Finally, the NLG gives a response based on the semantic frame.Now that we’ve seen how a typical dialogue system works, let’s clearly understand NLP, NLU, and NLG in detail. The procedure of determining mortgage rates is comparable to that of determining insurance risk. As demonstrated in the video below, mortgage chatbots can also gather, validate, and evaluate data. However, NLU lets computers understand “emotions” and “real meanings” of the sentences. For those interested, here is our benchmarking on the top sentiment analysis tools in the market.

NLP systems can extract subject-verb-object relationships, verb semantics, and text meaning from semantic analysis. Information extraction, question-answering, and sentiment analysis require this data. Across various industries and applications, NLP and NLU showcase their unique capabilities in transforming the way we interact with machines.

Thus, developing algorithms and techniques through which machines get the ability to process and then manipulate data (textual and spoken language) in a better way. Natural Language Processing(NLP) is a subset of Artificial intelligence which involves communication between a human and a machine using a natural language than a coded or byte language.

As seen in Figure 3, Google translates the Turkish proverb “Damlaya damlaya göl olur.” as “Drop by drop, it becomes a lake.” This is an exact word by word translation of the sentence. 7 min read – Six ways organizations use a private cloud to support ongoing digital transformation and create business value. The verb that precedes it, swimming, provides additional context to the reader, allowing us to conclude that we are referring to the flow of water in the ocean. The noun it describes, version, denotes multiple iterations of a report, enabling us to determine that we are referring to the most up-to-date status of a file. So, if you’re conversing with a chatbot but decide to stray away for a moment, you would have to start again. These handcrafted rules are made in a way that ensures the machine understands how to connect each element.

Natural languages are different from formal or constructed languages, which have a different origin and development path. For example, programming languages including C, Java, Python, and many more were created for a specific reason. An example of NLU in action is a virtual assistant understanding and responding to a user’s spoken request, such as providing weather information or setting a reminder. NLU and NLP work together in synergy, with NLU providing the foundation for understanding language and NLP complementing it by offering capabilities like translation, summarization, and text generation. NLU seeks to identify the underlying intent or purpose behind a given piece of text or speech.

Its primary objective is to empower machines with human-like language comprehension — enabling them to read between the lines, deduce context, and generate intelligent responses akin to human understanding. NLU tackles sophisticated tasks like identifying intent, conducting semantic analysis, and resolving coreference, contributing to machines’ ability to engage with language at a nuanced and advanced level. NLP is a field of computer science and artificial intelligence (AI) that focuses on the interaction between computers and humans using natural language. NLP is used to process and analyze large amounts of natural language data, such as text and speech, and extract meaning from it. NLG, on the other hand, is a field of AI that focuses on generating natural language output.

Both of these fields offer various benefits that can be utilized to make better machines. You’ll probably use Alexa or Siri to make the process smoother and save time. Chrissy Kidd is a writer and editor who makes sense of theories and new developments in technology. Formerly the managing editor of BMC Blogs, you can reach her on LinkedIn or at chrissykidd.com. The first successful attempt came out in 1966 in the form of the famous ELIZA program which was capable of carrying on a limited form of conversation with a user. In this context, another term which is often used as a synonym is Natural Language Understanding (NLU).

Understanding semantics requires context, inference, and word relationships. Complex languages with compound words or agglutinative structures benefit from tokenization. By splitting text into smaller parts, following processing steps can treat each token separately, collecting valuable information and patterns. We’ve seen that NLP primarily deals with analyzing the language’s structure and form, focusing on aspects like grammar, word formation, and punctuation. On the other hand, NLU is concerned with comprehending the deeper meaning and intention behind the language. NLU makes it possible to carry out a dialogue with a computer using a human-based language.

If you want to create robust autonomous machines, then it’s important that you cannot only process the input but also understand the meaning behind the words. Moreover, it is a multi-faceted analysis to understand the context of the data based on the textual environment. With NLU techniques, the system forms connections within the text and use external knowledge. The computational methods used in machine learning result in a lack of transparency into “what” and “how” the machines learn. This creates a black box where data goes in, decisions go out, and there is limited visibility into how one impacts the other.

Text abstraction, the original document is phrased in a linguistic way, text interpreted and described using new concepts, but the same information content is maintained. NLU enables computers to understand the sentiments expressed in a natural language used by humans, such as English, French or Mandarin, without the formalized syntax of computer languages. NLU also enables computers to communicate back to humans in their own languages. In machine learning (ML) jargon, the series of steps taken are called data pre-processing. The idea is to break down the natural language text into smaller and more manageable chunks. These can then be analyzed by ML algorithms to find relations, dependencies, and context among various chunks.

This hard coding of rules can be used to manipulate the understanding of symbols. Another key difference between these three areas is their level of complexity. NLP is a broad field that encompasses a wide range nlu vs nlp of technologies and techniques, while NLU is a subset of NLP that focuses on a specific task. NLG, on the other hand, is a more specialized field that is focused on generating natural language output.

In the statement “Apple Inc. is headquartered in Cupertino,” NER recognizes “Apple Inc.” as an entity and “Cupertino” as a location. Constituency parsing combines words into phrases, while dependency parsing shows grammatical dependencies. NLP systems extract subject-verb-object relationships and noun phrases using parsing and grammatical analysis. Our brains work hard to understand speech and written text, helping us make sense of the world. Two fundamental concepts of NLU are intent recognition and entity recognition. Generally, computer-generated content lacks the fluidity, emotion and personality that makes human-generated content interesting and engaging.

As a result, insurers should take into account the emotional context of the claims processing. As a result, if insurance companies choose to automate claims processing with chatbots, they must be certain of the chatbot’s emotional and NLU skills. It enables machines to produce appropriate, relevant, and accurate interaction responses. NLP excels in tasks that are related to processing and generating human-like language.

In such cases, salespeople in the physical stores used to solve our problem and recommended us a suitable product. In the age of conversational commerce, such a task is done by sales chatbots that understand user intent and help customers to discover a suitable product for them via natural language (see Figure 6). Data pre-processing aims to divide the natural language content into smaller, simpler sections.

These innovations will continue to influence how humans interact with computers and machines. As NLP algorithms become more sophisticated, chatbots and virtual assistants are providing seamless and natural interactions. Meanwhile, improving NLU capabilities enable voice assistants to understand user queries more accurately. NER uses contextual information, language patterns, and machine learning algorithms to improve entity recognition accuracy beyond keyword matching. NER systems are trained on vast datasets of named items in multiple contexts to identify similar entities in new text.

For example, a virtual assistant might use NLU to understand a user’s request to book a flight and then generate a response that includes flight options and pricing information. As humans, we can identify such underlying similarities almost effortlessly and respond accordingly. But this is a problem for machines—any algorithm will need the input to be in a set format, and these three sentences vary in their structure and format. And if we decide to code rules for each and every combination of words in any natural language to help a machine understand, then things will get very complicated very quickly. The future of NLU and NLP is promising, with advancements in AI and machine learning techniques enabling more accurate and sophisticated language understanding and processing.

Whether it’s NLP, NLU, or other AI technologies, our expert team is here to assist you. Tokenization, part-of-speech tagging, syntactic parsing, machine translation, etc. NLU can analyze the sentiment or emotion expressed in text, determining whether the sentiment is positive, negative, or neutral. This helps in understanding the overall sentiment or opinion conveyed in the text.

NLP full form is Natural Language Processing (NLP) is an exciting field that focuses on enabling computers to understand and interact with human language. It involves the development of algorithms and techniques that allow machines to read, interpret, and respond to text or speech in a way that resembles human comprehension. NLP consists of natural language generation (NLG) concepts and natural language understanding (NLU) to achieve human-like language processing.
