Guide to Natural Language Understanding NLU in 2023

For machines, human language, also referred to as natural language, is how humans communicate—most often in the form of text. It comprises the majority of enterprise data and includes everything from text contained in email, to PDFs and other document types, chatbot dialog, social media, etc. Systems will be trained to identify and respond to human emotions expressed in text and speech.

These diverse applications demonstrate the immense value that NLU brings to our interconnected world. From simplifying daily tasks with virtual assistants to revolutionizing customer support and decision-making across industries, NLU continues to redefine how we interact with technology and harness the power of language. NLU proceeds with syntax and grammar analysis after dissecting the text into tokens.

The Role of NLU in Artificial Intelligence

The last place that may come to mind that utilizes NLU is in customer service AI assistants. Natural Language Understanding is a big component of IVR since interactive voice response is taking in someone’s words and processing it to understand the intent and sentiment behind the caller’s needs. IVR makes a great impact on customer support teams that utilize phone systems as a channel since it can assist in mitigating support needs for agents. For example, entity analysis can identify specific entities mentioned by customers, such as product names or locations, to gain insights into what aspects of the company are most discussed. Sentiment analysis can help determine the overall attitude of customers towards the company, while content analysis can reveal common themes and topics mentioned in customer feedback.

For example, we define the DontKnow intent by creating a directory en and placing a file called DontKnow.exm in there. As can be seen, the examples can be provided by overriding the getExamples() method. In the healthcare industry, this technology has the potential to be a tremendous asset for organizations. This data can then be used to improve marketing campaigns or product offerings.

Collecting and analyzing personal data for NLU purposes raises privacy concerns, necessitating stringent safeguards to protect user information. Furthermore, the potential for bias in NLU models, which can perpetuate stereotypes or discriminate against certain groups, poses a pressing ethical challenge that demands ongoing attention and mitigation. As we explore Natural Language Understanding, we will dive deeper into how NLU works, its applications across various domains, the challenges it faces, and its promising future. NLU is not just a technological advancement; it’s a bridge that connects the vast realm of human communication with the limitless potential of artificial intelligence.

Despite this, the neural symbolic approach shows promise for creating systems that can understand human language. Automated reasoning is a powerful tool that can help machines understand human language’s meaning. For example, in an MRC task requiring freestyle answers, the model needs to first analyze the question and article. The NLU models introduced in the previous section can handle this text analysis task. Then, RNN is usually employed to produce text, since RNN can process text with varying lengths, which suits the text generation process of predicting new words given previous context. For example, NLP allows to capture spoken language in real-time, transcribe it, and return text- NLU goes an extra step to determine a user’s intent.

For example, clothing retailer Asos was able to increase orders by 300% using Facebook Messenger Chatbox, and it garnered a 250% ROI increase while reaching almost 4 times more user targets. Similarly, cosmetic giant Sephora increased its makeover appointments by 11% by using Facebook Messenger Chatbox. It’s the era of Big Data, and super-sized language models are the latest stars. We also offer an extensive library of use cases, with templates showing different AI workflows. Akkio also offers integrations with a wide range of dataset formats and sources, such as Salesforce, Hubspot, and Big Query.

Neri Van Otten is the founder of Spot Intelligence, a machine learning engineer with over 12 years of experience specialising in Natural Language Processing (NLP) and deep learning innovation. Speakers of less commonly used languages will gain access to advanced NLU applications through crowdsourced data collection and community-driven efforts. Many NLU advancements surround languages with abundant training data, leaving low-resource languages disadvantaged. Ensuring linguistic diversity and inclusivity in NLU research and applications remains challenging, as it requires concerted efforts to develop robust NLU capabilities for languages with limited resources. As NLU applications continue to increase, so do privacy and ethics concerns.

What is Natural Language Understanding?

Although NLG and NLU use independent mechanisms and grammars, they are both governed by a central ontology, which provides/restricts domain knowledge to the whole stage. As the parameters in a neural network are randomly initialized, the decoder will produce text of poor quality in the early stage. Since a generated word is fed into the next RNN module, the generation error will propagate. Under teacher forcing, the word generated by the decoder does not enter the next RNN module during training. This can avoid error propagation and alleviate the cold-start problem, resulting in faster convergence.

Whether it is a variety of levels or a shift from low level to high level, there is the phenomenon of ambiguity. That is, a string with the same format can be understood as different strings under different scenes or context and have different meanings. Under normal circumstances, the majority of these problems can be solved according to the rules of corresponding context and scenes. This is why we do not think natural language is ambiguous, and we can correctly communicate using natural language. On the other hand, as we can see, in order to eliminate it, much knowledge and inference are needed. The work cannot be finished by a few people in the short term; it remains a long-term and systematic task.
