NLP vs NLU vs NLG: Understanding the Differences by Tathagata Medium

This will empower your journey with confidence that you are using both terms in the correct context. 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 difference between nlp and nlu understand “emotions” and “real meanings” of the sentences. For those interested, here is our benchmarking on the top sentiment analysis tools in the market. However, when it comes to advanced and complex tasks of understanding deeper semantic layers of speech implementing NLP is not a realistic approach.

Businesses can benefit from NLU and NLP by improving customer interactions, automating processes, gaining insights from textual data, and enhancing decision-making based on language-based analysis. 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. NER systems scan input text and detect named entity words and phrases using various algorithms.

Together, this help AI converge to the end goal of developing an accurate understanding of natural language structure. NLP involves the use of computational techniques to analyze, interpret, and generate human language. It is a multidisciplinary field that combines linguistics, computer science, and artificial intelligence. The goal of NLP is to enable computers to understand human language and respond appropriately, even in situations where multiple interpretations may exist. Natural Language Processing is the process of analysing and understanding the human language.

It extracts pertinent details, infers context, and draws meaningful conclusions from speech or text data. While delving deeper into semantic and contextual understanding, NLU builds upon the foundational principles of natural language processing. Its primary focus lies in discerning the meaning, relationships, and intents conveyed by language. This involves tasks like sentiment analysis, entity linking, semantic role labeling, coreference resolution, and relation extraction.

NLU techniques such as sentiment analysis and sarcasm detection allow machines to decipher the true meaning of a sentence, even when it is obscured by idiomatic expressions or ambiguous phrasing. Natural language processing primarily focuses on syntax, which deals with the structure and organization of 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. The integration of NLP algorithms into data science workflows has opened up new opportunities for data-driven decision making.

Across various industries and applications, NLP and NLU showcase their unique capabilities in transforming the way we interact with machines. By understanding their distinct strengths and limitations, businesses can leverage these technologies to streamline processes, enhance customer experiences, and unlock new opportunities for growth and innovation. NLP employs both rule-based systems and statistical models to analyze and generate text. Linguistic patterns and norms guide rule-based approaches, where experts manually craft rules for handling language components like syntax and grammar. NLP’s dual approach blends human-crafted rules with data-driven techniques to comprehend and generate text effectively. Basically, with this technology, the aim is to enable machines to understand and interpret human 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. So, if you’re conversing with a chatbot but decide to stray away for a moment, you would have to start again. If you’re finding the answer to this question, then the truth is that there’s no definitive answer.

Entity recognition, intent recognition, sentiment analysis, contextual understanding, etc. The algorithms utilized in NLG play a vital role in ensuring the generation of coherent and meaningful language. They analyze the underlying data, determine the appropriate structure and flow of the text, select suitable words and phrases, and maintain consistency throughout the generated content.

NLU vs NLP: A comprehensive comparison

NLP groups together all the technologies that take raw text as input and then produces the desired result such as Natural Language Understanding, a summary or translation. In practical terms, NLP makes it possible to understand what a human being says, to process the data in the message, and to provide a natural language response. In order to be able to work and interact with us properly, machines need to learn through a natural language processing (NLP) system. By harnessing advanced algorithms, NLG systems transform data into coherent and contextually relevant text or speech.

NLU, on the other hand, deals with higher-level language understanding, considering meaning, context, and even sentiment. 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.

NLU Use Cases

These systems use NLP to understand the user’s input and generate a response that is as close to human-like as possible. NLP is also used in sentiment analysis, which is the process of analyzing text to determine the writer’s attitude or emotional state. NLU systems use similar techniques to NLP, but they also incorporate additional information that enhances their ability to understand human language. The system processes language input and attempts to match it to a predefined set of parameters. Once the system has identified the intended meaning of the language, it can generate appropriate responses or take the appropriate actions. NLP has a wide range of applications, including language translation, sentiment analysis, chatbots, and speech recognition.

NLP and NLU have made these possible and continue shaping the virtual communication field. Two subsets of artificial intelligence (AI), these technologies enable smart systems to grasp, process, and analyze spoken and written human language to further provide a response and maintain a dialogue. 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. NLU is used in a variety of applications, including virtual assistants, chatbots, and voice assistants.

It is easy to see why natural language understanding is an extremely important issue for companies that want to use intelligent robots to communicate with their customers. Customer feedback, brand monitoring, market research, and social media analytics use sentiment analysis. It reveals public opinion, customer satisfaction, and sentiment toward products, services, or issues. 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.

The callbot powered by artificial intelligence has an advanced understanding of natural language because of NLU. If this is not precise enough, human intervention is possible using a low-code conversational agent creation platform for instance. Natural Language Understanding (NLU) refers to the analysis of a written or spoken text in natural language and understanding its meaning.

These handcrafted rules are made in a way that ensures the machine understands how to connect each element. It doesn’t just do basic processing; instead, it comprehends and then extracts meaning from your data. Just by the name, you can tell that the initial goal of Natural Language Processing is processing and manipulation. It emphasizes the need to understand interactions between computers and human beings.
