Chatbots: When To Use NLP & When To Use NLU Medium
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. It provides the ability to give instructions to machines in a more easy and efficient manner. Text analysis solutions enable machines to automatically understand the content of customer support tickets and route them to the correct departments without employees having to open every single ticket. Not only does this save customer support teams hundreds of hours,it also helps them prioritize urgent tickets. Both NLP and NLU aim to make sense of unstructured data, but there is a difference between the two. Another difference between NLU and NLP is that NLU is focused more on sentiment analysis.
Such a chatbot builds a persona of customer support with immediate responses, zero downtime, round the clock and consistent execution, and multilingual responses. Natural Language Understanding provides machines with the capabilities to understand and interpret human language in a way that goes beyond surface-level processing. It is designed to extract meaning, intent, and context from text or speech, allowing machines to comprehend contextual and emotional touch and intelligently respond With AI and machine learning (ML), NLU(natural language understanding), NLP ((natural language processing), and NLG (natural language generation) have played an essential role in understanding what user wants. NLP makes it possible for computers to read text, hear speech and interpret it, measure sentiment and even determine which parts are relevant. It has become really helpful resolving ambiguity in language and adds numeric structure to the data for many downstream applications.
NLP & NLU use cases
To understand this, we first need to know what each term stands for and clarify any ambiguities. We as humans take the question from the top down and answer different aspects of the question. This informs the user that the basic gist of their utterance is not lost, and they need to articulate differently. And also the intents and entity change based on the previous chats check out below.
Here, they need to know what was said and they also need to understand what was meant. Conversely, NLU focuses on extracting the context and intent, or in other words, what was meant. 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.
What is Natural Language Understanding (NLU)?
The lack of formal regulation and NLP’s commercial value mean that claims of its effectiveness can be anecdotal or supplied by an NLP provider. NLP providers will have a financial interest in the success of NLP, so their evidence is difficult to use. Despite a lack of empirical evidence to support it, Bandler and Grinder published two books, The Structure of Magic I and II, and NLP took off.
Still, it can also enhance several existing technologies, often without a complete ‘rip and replace’ of legacy systems. This algorithmic approach uses statistical analysis of ‘training’ documents to establish rules and build its knowledge base. However, because language and grammar rules can be complex and contradictory, this algorithmic approach can sometimes produce incorrect results without human oversight and correction. 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.
There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. 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. 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. A natural language is one that has evolved over time via use and repetition.
This allows the system to provide a structured, relevant response based on the intents and entities provided in the query. That might involve sending the user directly to a product page or initiating a set of production option pages before sending a direct link to purchase the item. 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. While both technologies are strongly interconnected, NLP rather focuses on processing and manipulating language and NLU aims at understanding and deriving the meaning using advanced techniques and detailed semantic breakdown.
When it comes to natural language, what was written or spoken may not be what was meant. In the most basic terms, NLP looks at what was said, and NLU looks at what was meant. People can say identical things in numerous ways, and they may make mistakes when writing or speaking. They may use the wrong words, write fragmented sentences, and misspell or mispronounce words. NLP can analyze text and speech, performing a wide range of tasks that focus primarily on language structure. However, it will not tell you what was meant or intended by specific language.
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. NLU goes beyond the basic processing of language and is meant to comprehend and extract meaning from text or speech. As a result, NLU deals with more advanced tasks like semantic analysis, coreference resolution, and intent recognition.

With natural language processing and machine learning working behind the scenes, all you need to focus on is using the tools and helping them to improve their natural language understanding.

NLG systems enable computers to automatically generate natural language text, mimicking the way humans naturally communicate — a departure from traditional computer-generated text. Primarily focused on machine reading comprehension, NLU gets the chatbot to comprehend what a body of text means. NLU is nothing but an understanding of the text given and classifying it into proper intents.
