NLP vs NLU vs. NLG: the differences between three natural language processing concepts

nlp vs nlu

The field soon shifted towards data-driven statistical models that used probability estimates to predict the sequences of words. Though this approach was more powerful than its predecessor, it still had limitations in terms of scaling across large sequences and capturing long-range dependencies. The advent of recurrent neural networks (RNNs) helped address several of these limitations but it would take the emergence of transformer models in 2017 to bring NLP into the age of LLMs. The transformer model introduced a new architecture based on attention mechanisms. Unlike sequential models like RNNs, transformers are capable of processing all words in an input sentence in parallel. More importantly, the concept of attention allows them to model long-term dependencies even over long sequences.

However, syntactic analysis is more related to the core of NLU examples, where the literal meaning behind a sentence is assessed by looking into its syntax and how words come together. Using tokenisation, NLP processes can replace sensitive information with other values to protect the end user. With lemmatisation, the algorithm dissects the input to understand the root meaning of each word and then sums up the purpose of the whole sentence.

Whether it’s simple chatbots or sophisticated AI assistants, NLP is an integral part of the conversational app building process. And the difference between NLP and NLU is important to remember when building a conversational app because it impacts how well the app interprets what was said and meant by users. Suppose companies wish to implement AI systems that can interact with users without direct supervision. In that case, it is essential to ensure that machines can read the word and grasp the actual meaning. This helps the final solution to be less rigid and have a more personalised touch.

You’re the one creating content for Bloomberg, or CNN Money, or even a brokerage firm. You’ve done your content marketing research and determined that daily reports on the stock market’s performance could increase traffic to your site.

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.

The first step in natural language understanding is to determine the intent of what the user is saying. Upon successful determination of this, it can be used to filter out any irrelevant data for further processing. Instead, they want an answer as quickly as possible to make plans accordingly. To conclude, distinguishing between NLP and NLU is vital for designing effective language processing and understanding systems. By embracing the differences and pushing the boundaries of language understanding, we can shape a future where machines truly comprehend and communicate with humans in an authentic and effective way.

The terms NLP and NLU are often used interchangeably, but they have slightly different meanings. Developers need to understand the difference between natural language processing and natural language understanding so they can build successful conversational applications. 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. It enables the assistant to grasp the intent behind each user utterance, ensuring proper understanding and appropriate responses.

It’s easier to define such a branch of computer science as natural language understanding when opposing it to a better known-of and buzzwordy natural language processing. Both NLP and NLU are related but distinct fields within artificial intelligence that deal with the ability of computers to process and understand human language. As we continue to advance in the realms of artificial intelligence and machine learning, the importance of NLP and NLU will only grow.

The technology also utilizes semantic role labeling (SRL) to identify the roles and relationships of words or phrases in a sentence with respect to a specific predicate. 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.

Applications

Figure 4 depicts our sample of 5 use cases in which businesses should favor NLP over NLU or vice versa. 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. We’ll also examine when prioritizing one capability over the other is more beneficial for businesses depending on specific use cases. By the end, you’ll have the knowledge to understand which AI solutions can cater to your organization’s unique requirements. To break it down, NLU (Natural language understanding) and NLG (Natural language generation) are subsets of NLP.

This intelligent robotic assistant can also learn from past customer conversations and use this information to improve future responses. NLP is a broad field that encompasses a wide range of technologies and techniques. At its core, NLP is about teaching computers to understand and process human language. This can involve everything from simple tasks like identifying parts of speech in a sentence to more complex tasks like sentiment analysis and machine translation. In practical applications such as customer support, recommendation systems, or retail technology services, it’s crucial to seamlessly integrate these technologies for more accurate and context-aware responses.

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. NLP utilizes statistical models and rule-enabled systems to handle and juggle with language. It often relies on linguistic rules and patterns to analyze and generate text.

It starts with NLP (Natural Language Processing) at its core, which is responsible for all the actions connected to a computer and its language processing system. This involves receiving human input, processing it and putting out a response. Natural language processing is generally more suitable for tasks involving data extraction, text summarization, and machine translation, among others. Meanwhile, NLU excels in areas like sentiment analysis, sarcasm detection, and intent classification, allowing for a deeper understanding of user input and emotions. In addition to natural language understanding, natural language generation is another crucial part of NLP. While both these technologies are useful to developers, NLU is a subset of NLP.

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.

The problem is that human intent is often not presented in words, and if we only use NLP algorithms, there is a high risk of inaccurate answers. NLP has several different functions to judge the text, including lemmatisation and tokenisation. These technologies work together to create intelligent chatbots that can handle various customer service tasks. As we see advancements in AI technology, we can expect chatbots to have more efficient and human-like interactions with customers. Both should lead to the ordering of a new laptop from the company’s service catalog, but NLU is what allows AI to precisely define the intent of a given user no matter how they say it. As you can imagine, this requires a deep understanding of grammatical structures, language-specific semantics, dependency parsing, and other techniques.

Natural language processing is best used in systems where focusing on keywords and working through large amounts of text without focusing on sentiments or emotions is essential. It all comes down to breaking down the primary language we use every day, and it has been used across many products for many years now. Some common examples of NLP applications include editing software, search engines, chatbots, text summarisation, categorisation, mining and even part-of-speech tagging. NLP algorithms are used to understand the meaning of a user’s text in a machine, while NLU algorithms take actions and core decisions. A third algorithm called NLG (Natural Language Generation) generates output text for users based on structured data.

As the name suggests, the initial goal of NLP is language processing and manipulation. It focuses on the interactions between computers and individuals, with the goal of enabling machines to understand, interpret, and generate natural language. Its main aim is to develop algorithms and techniques that empower machines to process and manipulate textual or spoken language in a useful way. As such, it deals with lower-level tasks such as tokenization and POS tagging. Natural Language Processing focuses on the interaction between computers and human language.

They could use the wrong words, write sentences that don’t make sense, or misspell or mispronounce words. 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.

Though looking very similar and seemingly performing the same function, NLP and NLU serve different purposes within the field of human language processing and understanding. The key distinctions are observed in four areas and revealed at a closer look. These approaches are also commonly used in data mining to understand consumer attitudes. In particular, sentiment analysis enables brands to monitor their customer feedback more closely, allowing them to cluster positive and negative social media comments and track net promoter scores. By reviewing comments with negative sentiment, companies are able to identify and address potential problem areas within their products or services more quickly.
