NLP vs NLU: Whats The Difference? BMC Software Blogs

At the most sophisticated level, they should be able to hold a conversation about anything, which is true artificial intelligence. Anybody who has used Siri, Cortana, or Google Now while driving will attest that dialogue agents are already proving useful, and going beyond their current level of understanding would not necessarily improve their function. Most other bots out there are nothing more than a natural language interface into an app that performs one specific task, such as shopping or meeting scheduling.

Sentiment Analysis is these days used widely in multiple industries, it can help in understanding customer reviews about a product. Understanding the collective meaning of dialogues like “show me the best recipes” is connected to food is the level of understanding computers develop in this step. In this step NLU groups the sentences, and tries to understand their collective meaning. Based on the previous logic, NLU tries to decipher the meaning of combined sentences.

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. A natural language is one that has evolved over time via use and repetition. Latin, English, Spanish, and many other spoken languages are all languages that evolved naturally over time. Natural Language Understanding enables machines to understand a set of text by working to understand the language of the text. There are so many possible use-cases for NLU and NLP and as more advancements are made in this space, we will begin to see an increase of uses across all spaces.

This can help you identify customer pain points, what they like and dislike about your product, and what features they to see in the future. NLU can help marketers personalize their campaigns to pierce through the noise. For example, NLU can be used to segment customers into different groups based on their interests and preferences. This allows marketers to target their campaigns more precisely and make sure their messages get to the right people.

Data capture is the process of extracting information from paper or electronic documents and converting it into data for key systems. Another challenge that NLU faces is syntax level ambiguity, where the meaning of a sentence could be dependent on the arrangement of words. In addition, referential ambiguity, which occurs when a word could refer to multiple entities, makes it difficult for NLU systems to understand the intended meaning of a sentence. If accuracy is paramount, go only for specific tasks that need shallow analysis.

• As such, it deals with lower-level tasks such as tokenization and POS tagging.
• With an eye on surface-level processing, NLP prioritizes tasks like sentence structure, word order, and basic syntactic analysis, but it does not delve into comprehension of deeper semantic layers of the text or speech.
• The tech builds upon the foundational elements of NLP but delves deeper into semantic and contextual language comprehension.
• They are so advanced and innovative that they appear as if a real human being has written them.
• 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.
