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

What NLP, NLU, and NLG Mean, and How They Help With Running Your Contact Center

What is the difference between NLP and NLU: Business Use Cases

Omnichannel bots can be extremely good at what they do if they are well-fed with data. The more linguistic information an NLU-based solution onboards, the better of a job it can do in customer-assisting tasks like routing calls more effectively. Thanks to machine learning (ML),  software can learn from its past experiences — in this case, previous conversations with customers. When supervised, ML can be trained to effectively recognise meaning in speech, automatically extracting key information without the need for a human agent to get involved. Thus, simple queries (like those about a store’s hours) can be taken care of quickly while agents tackle more serious problems, like troubleshooting an internet connection. All of which helps improve the customer experience, and makes your contact centre more efficient.

Over the years, statistical modeling techniques such as Hidden Markov Models were used to convert speech to text by performing mathematical calculations in order to determine what was spoken. Automated natural language generation can help customer service teams resolve issues faster and provide better service. For example, NLG can reduce customer support calls by generating natural-sounding responses to customer questions or requests. In fact, thanks to a new, powerful language model like GPT-3, many commercially available artificial intelligence and machine learning tools now offer sophisticated ways to generate human language using machines. In NLU systems, natural language input is typically in the form of either typed or spoken language. Text input can be entered into dialogue boxes, chat windows, and search engines.

What is Natural Language Understanding (NLU)?

NLP also can help analyze large databases to gather a deeper level of intelligence for making big decisions, a use case that carries lots of potential for scaling up. IBM Watson currently is being used to help manage an AI-driven stock index that evaluates potential investments based on in-depth analysis of data gathered on the largest publicly traded corporations. AI has become crucial in business as well, and NLP is seen as a major area of growth for many companies’ AI strategies.

  • Syntax parsing is a critical preparatory task in sentiment analysis

    and other natural language processing features as it helps uncover the meaning and intent.

  • NLP involves analyzing a corpus (an extensive collection of texts) to understand its structure and content.
  • NLU often involves incorporating external knowledge sources, such as ontologies, knowledge graphs, or commonsense databases, to enhance understanding.
  • Rule-based systems use a set of predefined rules to interpret and process natural language.

NLU can be used to extract entities, relationships, and intent from a natural language input. Data Analytics is a field of NLP that uses machine learning to extract insights from large data sets. This can be used to identify trends and patterns in data, which could be helpful for businesses looking to make predictions about their future. The output transformation is the final step in NLP and involves transforming the processed sentences into a format that machines can easily understand.

What is Natural Language Understanding (NLU) and how is it used in practice?

Sentiment analysis is the process of determining the emotional tone or opinions expressed in a piece of text, which can be useful in understanding the context or intent behind the words. A subfield of artificial intelligence and linguistics, NLP provides the advanced language analysis and processing that allows computers to make this unstructured human language data readable by machines. It can use many different methods to accomplish this, from tokenization, lemmatization, machine translation and natural language understanding.

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 on how they are used. For example, in NLU, various ML algorithms are used to identify the sentiment, perform Name Entity Recognition (NER), process semantics, etc.

Voice assistants

NLU is used in a variety of applications, including virtual assistants, chatbots, and voice assistants. These systems use NLU to understand the user’s input and generate a response that is tailored to their needs. For example, a virtual assistant might use NLU to understand a user’s request to book a flight and then generate a response that includes flight options and pricing information. Statistical models use machine learning algorithms such as deep learning to learn the structure of natural language from data. Hybrid models combine the two approaches, using machine learning algorithms to generate rules and then applying those rules to the input data.

  • These models analyzed large text corpora to discern linguistic trends, allowing for more adaptive and context-aware language processing.
  • Machine Translation, also known as automated translation, is the process where a computer software performs language translation and translates text from one language to another without human involvement.
  • The experience of using a smartphone, for example, wouldn’t be quite the same without the ability to pull up a map with a computerized voice navigating your next turn.

With NLQ, you can question a database in natural language, have that question translated to SQL, and receive the answer (along with the SQL query used to find it). Instead of relying solely on A/B testing result data and visualizations, NLQ allows marketers to ask deeper questions of the data and get a clear answer. Google leverages the power of Natural Language Processing (NLP) to understand and process user intent. Using NLP, Google can comprehend and classify user queries more accurately, allowing swift delivery of the most relevant results.

The buying public is increasingly dependent on NLP-led interactions

NLU is a computer technology that enables computers to understand and interpret natural language. It is a subfield of artificial intelligence that focuses on the ability of computers to understand and interpret human language. NLU, on the other hand, is more concerned with the higher-level understanding.

What is the difference between NLP and Use Cases

Natural Language Processing, a fascinating subfield of computer science and artificial intelligence, enables computers to understand and interpret human language as effortlessly as you decipher the words in this sentence. It also facilitates sentiment analysis, which involves determining the sentiment or emotion expressed in a piece of text, and information retrieval, where machines retrieve relevant information based on user queries. NLP has the potential to revolutionize industries such as healthcare, customer service, information retrieval, and language education, among others.

Apps such as voice assistants and NLP-based chatbots can then use these language rules to process and generate a conversation. These technologies enable machines to understand and respond to natural language, making interactions with virtual assistants and chatbots more human-like. Additionally, NLU systems can use machine learning algorithms to learn from past experience and improve their understanding of natural language. Syntax parsing is the process of segmenting a sentence into its component parts. It’s important to know where subjects

start and end, what prepositions are being used for transitions between sentences, how verbs impact nouns and other

syntactic functions to parse syntax successfully.

The transformer architecture was introduced in the paper “

Attention is All You Need” by Google Brain researchers. It can be used to analyze social media posts,

blogs, or other texts for the sentiment. Companies like Twitter, Apple, and Google have been using natural language

processing techniques to derive meaning from social media activity. Topic models can be constructed using statistical methods or other machine learning techniques like deep neural

networks.

This frees human analysts to focus on important work, such as client relationships. Natural Language Generation (NLG) is used in the insurance industry to automate the creation of written documents such as claims reports, policy summaries, and customer communications. It can also generate data-driven insights and recommendations for underwriters and actuaries. By using NLG, insurance companies can save time and resources while improving the accuracy and consistency of their written communications. Financial institutions use NLP to analyze market data, reduce risks, and make better decisions. NLP and other natural language solutions can also assist in financial crime detection.

Natural Language Generation(NLG) is a sub-component of Natural language processing that helps in generating the output in a natural language based on the input provided by the user. This component responds to the user in the same language in which the input was provided say the user asks something in English then the system will return the output in English. Knowledge of that relationship and subsequent action helps to strengthen the model. NLQ allows humans to ask questions of data , using everyday language as they would when communicating with another human, to find the information they need to make business decisions. NLQ input consists solely of terms or phrases spoken naturally or entered as they would be spoken, without any non-language characters. This capability allows humans to ask questions of their data in a natural way, providing a human experience for interacting with computers.
