All these sentences have the same underlying question, which is to enquire about today’s weather forecast. 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. Check out how the painstaking tasks of analyzing massive volumes of data and generating reports can be automated for a boost in productivity and revenue.
Natural Language Understanding: What It Is and How It Differs from NLP
But this new image will not be pulled from its training data—it’ll be an original image INSPIRED from the dataset. Here the user intention is playing cricket Chat GPT but however, there are many possibilities that should be taken into account. NLU is about understanding language, and NLG is about generating language.
However, these models may soon be able to interpret hand gestures and images as well. That said, it’s worth noting that as the technology develops over time, this is expected to improve. In short, conversational AI allows humans to have life-like interactions with machines. Tech Report is one of the oldest hardware, news, and tech review sites on the internet.

It helps your content get in front of the right audience with the right search intent. From search engines trying to understand search queries to chatbots talking like humans, NLU, NLP, and NLG are breakthroughs in technology that will change the way we interact with computers forever. Marketers use NLG to program machines to generate human-sounding text in response to the result of the NLU processes. For example, if we are developing a voice assistant of our own, you would want it to speak, and that’s what NLG helps you achieve. Only 20% of data on the internet is structured data and usable for analysis. The rest 80% is unstructured data, which can’t be used to make predictions or develop algorithms.
Conversational AI vs Chatbot: Is There a Difference?
Structured data is important for efficiently storing, organizing, and analyzing information. Phrazor, an augmented analytics tool uses advanced AI technology and machine learning to pull insights from raw data and present them in simple and succinct summaries, augmented by visuals. Discover the role of natural language generation in democratizing business intelligence and building a fully data-driven enterprise.
Have you ever wondered how Alexa, ChatGPT, or a customer care chatbot can understand your spoken or written comment and respond appropriately? NLP and NLU, two subfields of artificial intelligence (AI), facilitate understanding and responding to human language. Both of these technologies are beneficial to companies in various industries.
Carvana, a leading tech-driven car retailer known for its multi-story car vending machines, has significantly improved its operations using Epicor’s AI and ML technologies. Krishi is an eager Tech Journalist and content writer for both B2B and B2C, with a focus on making the process of purchasing software easier for businesses and enhancing their online presence and SEO. Although AI models are also prone to hallucinations, companies are working on fixing these issues.
Natural Language Processing is at the core of all conversational AI platforms. In conversational AI interactions, a machine must deduce meaning from a line of text by converting it into a data form it can understand. This allows it to select an appropriate response based on keywords it detects difference between nlp and nlu within the text. Other Natural Language Processing tasks include text translation, sentiment analysis, and speech recognition. Natural language understanding is a subset of machine learning that helps machines learn how to understand and interpret the language being used around them.
Robotic Process Automation, also known as RPA, is a method whereby technology takes on repetitive, rules-based data processing that may traditionally have been done by a human operator. Both Conversational AI and RPA automate previous manual processes but in a markedly different way. Increasingly, however, RPA is being referred to as IPA, or Intelligent Process Automation, using AI technology to understand and take on increasingly complex tasks.
Or, if you have a lot of information from a market survey, you can use NLU to pull out statistical information and get a sense of what all the answers mean. Video ads, on the other hand, can use NLP to figure out what customers need, want, and feel about a product and make more effective https://chat.openai.com/ video ads that connect with the target audience. Given that the pros and cons of rule-based and AI-based approaches are largely complementary, CM.com’s unique method combines both approaches. This allows us to find the best way to engage with users on a case-by-case basis.
The major difference between the NLU and NLP is that NLP focuses on building algorithms to recognize and understand natural language, while NLU focuses on the meaning of a sentence. That’s why companies are using natural language processing to extract information from text. Artificial intelligence is becoming an increasingly important part of our lives. However, when it comes to understanding human language, technology still isn’t at the point where it can give us all the answers. The algorithms we mentioned earlier contribute to the functioning of natural language generation, enabling it to create coherent and contextually relevant text or speech. NLU analyzes data using algorithms to determine its meaning and reduce human speech into a structured ontology consisting of semantic and pragmatic definitions.
For example, in NLU, various ML algorithms are used to identify the sentiment, perform Name Entity Recognition (NER), process semantics, etc. NLU algorithms often operate on text that has already been standardized by text pre-processing steps. 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.
With NLP integrated into an IVR, it becomes a voice bot solution as opposed to a strict, scripted IVR solution. Voice bots allow direct, contextual interaction with the computer software via NLP technology, allowing the Voice bot to understand and respond with a relevant answer to a non-scripted question. It allows callers to interact with an automated assistant without the need to speak to a human and resolve issues via a series of predetermined automated questions and responses. Still, it can also enhance several existing technologies, often without a complete ‘rip and replace’ of legacy systems.
Power of collaboration: NLP and NLU working together
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. Given the data, it analyzes it and generates narratives in conversational language. It goes way beyond template-based systems, having been configured with the domain knowledge and experience of a human expert to produce well-researched, accurate output within seconds.
This transparency makes symbolic AI an appealing choice for those who want the flexibility to change the rules in their NLP model. This is especially important for model longevity and reusability so that you can adapt your model as data is added or other conditions change. Questionnaires about people’s habits and health problems are insightful while making diagnoses.

With BMC, he supports the AMI Ops Monitoring for Db2 product development team. His current active areas of research are conversational AI and algorithmic bias in AI. In the world of AI, for a machine to be considered intelligent, it must pass the Turing Test. A test developed by Alan Turing in the 1950s, which pits humans against the machine.
While natural language understanding focuses on computer reading comprehension, natural language generation enables computers to write. NLG is the process of producing a human language text response based on some data input. This text can also be converted into a speech format through text-to-speech services.
If a developer wants to build a simple chatbot that produces a series of programmed responses, they could use NLP along with a few machine learning techniques. However, if a developer wants to build an intelligent contextual assistant capable of having sophisticated natural-sounding conversations with users, they would need NLU. NLU is the component that allows the contextual assistant to understand the intent of each utterance by a user. Without it, the assistant won’t be able to understand what a user means throughout a conversation. And if the assistant doesn’t understand what the user means, it won’t respond appropriately or at all in some cases.
Despite their prevalence in everyday activities, these two distinct technologies are often misunderstood and many people use these terms interchangeably. VAs are by far one of the most well-known applications of conversational AI—we are all familiar with Alexa and Siri. ‘Suggested feeds,’ like those on e-commerce websites, also use conversational AI to suggest products you may like based on your browsing and buying habits.
Let’s illustrate this example by using a famous NLP model called Google Translate. 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. Our open source conversational AI platform includes NLU, and you can customize your pipeline in a modular way to extend the built-in functionality of Rasa’s NLU models. You can learn more about custom NLU components in the developer documentation, and be sure to check out this detailed tutorial. 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.
In other words, NLP lets people and machines talk to each other naturally in human language and syntax. NLP-enabled systems are intended to understand what the human said, process the data, act if needed and respond back in language the human will understand. On the other hand, natural language processing is an umbrella term to explain the whole process of turning unstructured data into structured data.
It involves tasks like entity recognition, intent recognition, and context management. ” the chatbot uses NLU to understand that the customer is asking about the business hours of the company and provide a relevant response. NLP processes flow through a continuous feedback loop with machine learning to improve the computer’s artificial intelligence algorithms. Rather than relying on keyword-sensitive scripts, NLU creates unique responses based on previous interactions. For instance, a simple chatbot can be developed using NLP without the need for NLU. However, for a more intelligent and contextually-aware assistant capable of sophisticated, natural-sounding conversations, natural language understanding becomes essential.
Gone are the days when chatbots could only produce programmed and rule-based interactions with their users. Back then, the moment a user strayed from the set format, the chatbot either made the user start over or made the user wait while they find a human to take over the conversation. Going back to our weather enquiry example, it is NLU which enables the machine to understand that those three different questions have the same underlying weather forecast query.
Using a set of linguistic guidelines coded into the platform that use human grammatical structures. However, this approach requires the formulation of rules by a skilled linguist and must be kept up-to-date as issues are uncovered. This can drain resources in some circumstances, and the rule book can quickly become very complex, with rules that can sometimes contradict each other. For example, executives and senior management might want summary information in the form of a daily report, but the billing department may be interested in deeper information on a more focused area. Companies are also using NLP technology to improve internal support operations, providing help with internal routing of tickets or support communication. Using NLP, every inbound message and request can be reviewed and routed to the correct parties quickly with fewer errors.
For instance, take the English word “running.” NLP helps computers understand that this word is an adjective of “run” and has a similar meaning. For them, it’s all about understanding what a searcher is looking for and providing the best sources of information on that topic. AI technologies like NLP, NLU, and NLG let users use advanced computing to find the most relevant information for their search query.
This component responds to the user in the same language in which the input was provided say the user asks something in English then the system will return the output in English. Based on some data or query, an NLG system would fill in the blank, like a game of Mad Libs. But over time, natural language generation systems have evolved with the application of hidden Markov chains, recurrent neural networks, and transformers, enabling more dynamic text generation in real time.
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. NLU focuses on understanding human language, while NLP covers the interaction between machines and natural language. NLP is an umbrella term which encompasses any and everything related to making machines able to process natural language—be it receiving the input, understanding the input, or generating a response. Grammar complexity and verb irregularity are just a few of the challenges that learners encounter.
