NLU interprets written or spoken language to extract meaning and understand the intentions behind it. NLU is used in chatbots, virtual assistants like Siri, Alexa, or Cortana, and language translation apps to “understand” human interaction. The advancement of technology has led to the development of innovative tools such as AI natural language generation (NLG). This system utilizes deep learning algorithms and machine learning techniques to automate the creation of human-like text. While it offers numerous benefits in various industries, concerns have been raised about its potential bias. Natural language processing extracts relevant pieces of data from natural text or speech using a wide range of techniques.
- Conversational AI bots like Alexa, Siri, Google Assistant incorporate NLU and NLG to achieve the purpose.
- This termination is usually a termination token ( in the figures) or a max length criteria.
- It can generate text from structured data sources such as databases, or from unstructured sources like audio or video recordings.
- NLP can be used to analyze the sentiment or emotion behind a piece of text, such as a customer review or social media post.

- Fine-tuning makes GPT-1 different from other state-of-the-art technologies, as it allows for a higher quality of language comprehension.
In a vanilla version of decoding, at each step of the sequence, the token with highest probability in the softmax layer is generated. This is called ‘greedy decoding’, but it has been shown to produce suboptimal text. During training, we are given an input (text/image/audio) and the ‘gold label text’ that we want the system to learn to generate for that particular input. The input goes through the encoder and produces a feature vector that is used as the input to decoder.
What is Natural Language Generation Software?
Xie et al. [154] proposed a neural architecture where candidate answers and their representation learning are constituent centric, guided by a parse tree. Under this architecture, the search space of candidate answers is reduced while preserving the hierarchical, syntactic, and compositional structure among constituents. Seunghak et al. [158] designed a Memory-Augmented-Machine-Comprehension-Network (MAMCN) to handle dependencies faced in reading comprehension. The model achieved state-of-the-art performance on document-level using TriviaQA and QUASAR-T datasets, and paragraph-level using SQuAD datasets. The model performs better when provided with popular topics which have a high representation in the data (such as Brexit, for example), while it offers poorer results when prompted with highly niched or technical content.

This involves analyzing the relationships between words and phrases in a sentence to infer meaning. For example, in the sentence “I need to buy a new car”, the semantic analysis would involve understanding that “buy” means to purchase and that “car” refers to a mode of transportation. While beam search tends to improve the quality of generated output, it has its own issues. Although it can be controlled by the max parameter (of step 4), it’s another hyperparameter to be reckoned with. To aggregate and analyze insights, companies need to look for common themes and trends across customer conversations.
Natural Language Processing
One way to mitigate this is by using the LLM as a labeling copilot to generate data to train smaller models. This approach has been used successfully in various applications, such as text classification and named entity recognition. To summarize, NLU is about understanding human language, while NLG is about generating human-like language. Both areas are important for building intelligent conversational agents, chatbots, and other NLP applications that interact with humans naturally.
NLP chatbots use feedback to analyze customer queries and provide a more personalized service. Many companies are using chatbots to streamline their workflows and to automate their customer services for a better customer experience. NLP is also being used in speech recognition, which enables machines such as device assistants to identify words or phrases from spoken language and convert them into a readable format. Another use case example of NLP is machine translation, or automatically converting data from one natural language to another. Natural language understanding (NLU) is a branch of artificial intelligence (AI) that enables machines to interpret and understand human language.
Text Generation using Statistical Language Models
Sentiment analysis is extracting meaning from text to determine its emotion or sentiment. Semantic analysis is analyzing context and text structure to accurately distinguish the meaning of words that have more than one definition. Intent recognition is identifying words that signal user intent, often to determine actions to take based on users’ responses. Many text mining, text extraction, and NLP techniques exist to help you extract information from text written in a natural language. Neural networks are so powerful that they’re fed raw data (words represented as vectors) without any pre-engineered features.
Today’s machines can analyze more language-based data than humans, without fatigue and in a consistent, unbiased way. Considering the staggering amount of unstructured data that’s generated every day, from medical records to social media, automation will be critical to analyze text and speech data efficiently thoroughly. Information extraction is concerned with identifying phrases of interest of textual data.

However, you can perform high-level tokenization for more complex structures, like words that often go together, otherwise known as collocations (e.g., New York). Ultimately, the more data these NLP algorithms are fed, the more accurate the text analysis models will be. NLP is employed to analyze the connections and interactions between users on social media platforms. By examining the content of posts, comments, and messages, as well as network structures, NLP can help identify communities, influencers, or key users within a social network.
There are also several libraries that are specifically designed for deep learning-based NLP tasks, such as AllenNLP and PyTorch-NLP. Continuing, some other can provide tools for specific NLP tasks like intent parsing (Snips NLU), topic modeling (BigARTM), and part-of-speech tagging and dependency parsing (jPTDP). The first step in developing an NLP algorithm is to determine the scope of the problem that it is intended to solve. This involves defining the input and output data, as well as the specific tasks that the algorithm is expected to perform. For example, an NLP algorithm might be designed to perform sentiment analysis on a large corpus of customer reviews, or to extract key information from medical records.

Sentiment analysis (seen in the above chart) is one of the most popular NLP tasks, where machine learning models are trained to classify text by polarity of opinion (positive, negative, neutral, and everywhere in between). Natural language processing algorithms must often deal with ambiguity and subtleties in human language. For example, words can have multiple meanings depending on their contrast or context. Semantic analysis helps to disambiguate these by taking into account all possible interpretations when crafting a response. It also deals with more complex aspects like figurative speech and abstract concepts that can’t be found in most dictionaries.
What are the different types of natural language generation?
Natural Language Generation (NLG) in AI can be divided into three categories based on its scope: Basic NLG, Template-driven NLG, and Advanced NLG.
