NLP vs NLU: Whats The Difference? BMC Software Blogs

The file should be placed in the resource folder of same package folder as the entity class. This is very similar to dealing with intent examples in a separate file. Bharat Saxena has over 15 years of experience in software product development, and has worked in various stages, from coding to managing a product.

  • Natural language generation is another subset of natural language processing.
  • As can be seen, the examples can be provided by overriding the getExamples() method.
  • Reach new audiences by unlocking insights hidden deep in experience data and operational data to create and deliver content audiences can’t get enough of.
  • However, as IVR technology advanced, features such as NLP and NLU have broadened its capabilities and users can interact with the phone system via voice.
  • There are several ways of accomplishing this, lists of events is the first.
  • NLU interprets language to automatically sort queries into specific, pre-defined topics, from where it is easier to deliver a favourable outcome to the user.

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. After all, different sentences can mean the same thing, and, vice versa, the same words can mean different things depending on how they are used. Natural languages are different from formal or constructed languages, which have a different origin and development path.

The group label can, for example, be used to define different orders. In the following example, the group label specifies which toppings go with which pizza and what size each pizza should be. Adapt to new evolving tech stack solutions to ensure informed business decisions.

ELIZA worked by simple parsing and substitution of key words into canned phrases and Weizenbaum sidestepped the problem of giving the program a database of real-world knowledge or a rich lexicon. Yet ELIZA gained surprising popularity as a toy project and can be seen as a very early precursor to current commercial systems such as those used by Enterprise Strategy Group research shows organizations are struggling with real-time data insights. While AI has developed into an important aid for making decisions, infusing data into the workflows of business users in real …

What is natural language processing?

You are probably already using some NLU functions in your business without realising it. Even if you are not, you are almost guaranteed to be doing so in your day to day life. As we highlighted above, the purpose of NLU is to interpret human communication in context.

Does natural language understanding NLU work?

NLU works by using algorithms to convert human speech into a well-defined data model of semantic and pragmatic definitions. The aim of intent recognition is to identify the user's sentiment within a body of text and determine the objective of the communication at hand.

Thus, it helps businesses to understand customer needs and offer them personalized products. NLU is a subset of NLP that teaches computers what a piece of text or spoken speech means. NLU leverages AI to recognize language attributes such as sentiment, semantics, context, and intent. It enables computers to understand subtleties and variations in language.


This book is for managers, programmers, directors – and anyone else who wants to learn machine learning. To pass the test, a human evaluator will interact with a machine and another human at the same time, each in a different room. NLP focuses on processing the text in a literal sense, like what was said.

  • Suppose that a shopper queries “Show me classy black dresses for under $500.” This query defines the product , product type , price point (less than $500), and personal tastes and preferences .
  • It is inefficient, as the search process has to be repeated if an error occurs.
  • NLU can greatly help journalists and publishers extract answers to complex questions from deep within content using natural language interaction with content archives.
  • In the examples above, we have assumed that the EnumEntity only has one value field, which has the name value and is of the type String.
  • To solve a single problem, firms can leverage hundreds of solution categories with hundreds of vendors in each category.
  • NLU pushes through such errors to determine the user’s intent, even if their written or spoken language is flawed.

The aim of NLU is to allow computer software to understand natural human language in verbal and written form. NLU works by using algorithms to convert human speech into a well-defined data model of semantic and pragmatic definitions. Sometimes people know what they are looking for but do not know the exact name of the good. 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 .

With text analysis solutions like MonkeyLearn, machines can 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, but it also helps them prioritize urgent tickets. Before a computer can process unstructured text into a machine-readable format, first machines need to understand the peculiarities of the human language. For example, if a user is translating data with an automatic language tool such as a dictionary, it will perform a word-for-word substitution. However, when using machine translation, it will look up the words in context, which helps return a more accurate translation.

You may see how conversational AI tools can help your business or institution automate various procedures by requesting a demo from Haptik. 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. Note that you explicitly have to forget entities even if they are loaded/initialized through an intent.

While nlu definition 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.
