NLP vs NLU: Whats The Difference? BMC Software Blogs

Recommendations on Spotify or Netflix, auto-correct and auto-reply, virtual assistants, and automatic email categorization, to name just a few. NLP is concerned with how computers are programmed to process language and facilitate “natural” back-and-forth communication between computers and humans. Both NLP and NLU aim to make sense of unstructured data, but there is a difference between the two. NLU also enables computers to communicate back to humans in their own languages. Natural Language Generation is what happens when computers write language.

Machines can find patterns in numbers and statistics, pick up on subtleties like sarcasm which aren’t inherently readable from text, or understand the true purpose of a body of text or a speech. This enables machines to produce more accurate and appropriate responses during interactions. Processing and understanding language is not just about training a dataset. It contains several fields such as data science, linguistic techniques, computer science, and more. Have you ever sat in front of your computer, unsure of what actions to take in order to get your job done? If you’ve ever wished that you could just talk to it and have it understand what you say, then you’re in luck.

What is the Difference Between NLP, NLU, and NLG?

Natural Language Processing is what happens when computers read language. Be on the lookout for huge influencers in IT such as Apple and Google to keep investing in NLP so that they can create human-like systems. The worldwide market for NLP is set to eclipse $22 billion by 2025, so it’s only a matter of time before these tech giants transform how humans interact with technology. For instance, the address of the home a customer wants to cover has an impact on the underwriting process since it has a relationship with burglary risk.

According to Zendesk, tech companies receive more than 2,600 customer support inquiries per month. Using NLU technology, you can sort unstructured data (email, social media, live chat, etc.) by topic, sentiment, and urgency . These tickets can then be routed directly to the relevant agent and prioritized. Natural language understanding is a subfield of natural language processing , which involves transforming human language into a machine-readable format.

Whether you want to increase customer loyalty or boost brand perception, we’re here for your success with everything from program design, to implementation, and fully managed services. Automated reasoning is a subfield of cognitive science that is used to automatically prove mathematical theorems or make logical inferences about a medical diagnosis. It gives machines a form of reasoning or logic, and allows them to infer new facts by deduction.

The management of context in natural-language understanding can present special challenges. A large variety of examples and counter examples have resulted in multiple approaches Difference Between NLU And NLP to the formal modeling of context, each with specific strengths and weaknesses. It’s taking the slangy, figurative way we talk every day and understanding what we truly mean.

natural language understanding (NLU)

NLU engine benchmarking operations give computers the information required to converse with someone without them even knowing that they are not communicating with a real person. Software solutions equipped with machine learning competencies such as NLU have been a game changer when it comes to the gathering of data. Modern data environments are too large for a human or team to feasibly analyze, while NLU-powered machines can do it in the blink of an eye. Businesses that implement NLU technology are at a considerable advantage over the competition.

If you’d like to learn how to create better content faster, visit our blog. But it can actually free up editorial professionals by taking on the rote tasks of content creation and allowing them to create the valuable, in-depth content for which your visitors are searching. Imagine you had a tool that could read and interpret content, find its strengths and its flaws, and then write blog posts that meet the needs of both search engines and your users. The Marketing Artificial Intelligence Institute underlines how important all of this tech is to the future of content marketing. One of the toughest challenges for marketers, one that we address in several posts, is the ability to create content at scale. Your Google Home device listens to your query, and then NLP kicks in.

This will empower your journey with confidence that you are using both terms in the correct context. There is, therefore, a significant amount of investment occurring in NLP sub-fields of study like semantics and syntax. False patient reviews can hurt both businesses and those seeking treatment. Sentiment analysis, thus NLU, can locate fraudulent reviews by identifying the text’s emotional character. For instance, inflated statements and an excessive amount of punctuation may indicate a fraudulent review. Let’s illustrate this example by using a famous NLP model called Google Translate.

All this has sparked a lot of interest both from commercial adoption and academics, making NLP one of the most active research topics in AI today. In machine learning 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. As humans, we can identify such underlying similarities almost effortlessly and respond accordingly. 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.

Understanding NLU engine

Without sophisticated software, understanding implicit factors is difficult. Natural Language Understanding seeks to intuit many of the connotations and implications that are innate in human communication such as the emotion, effort, intent, or goal behind a speaker’s statement. It uses algorithms and artificial intelligence, backed by large libraries of information, to understand our language. These three terms are often used interchangeably but that’s not completely accurate.

• In fact, chatbots have become so advanced; you may not even know you’re talking to a machine.
• NLU-powered chatbots can offer immediate and seamless customer reports at any time of day and in multiple languages.
• In this example, the NLU technology is able to surmise that the person wants to purchase tickets, and the most likely mode of travel is by airplane.
• 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 Ask.com.
• However, if a developer wants to build an intelligent contextual assistant capable of having sophisticated natural-sounding conversations with users, they would need NLU.
• In conclusion, I hope now you have a better understanding of the key differences between NLU and NLP.
