NLU vs NLP: Unlocking the Secrets of Language Processing in AI

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. NLU also enables the development of conversational agents and virtual assistants, which rely on natural language input to carry out simple tasks, answer common questions, and provide assistance to customers. Another important application of NLU is in driving intelligent actions through understanding natural language. This involves interpreting customer intent and automating common tasks, such as directing customers to the correct departments. This not only saves time and effort but also improves the overall customer experience.

Complex languages with compound words or agglutinative structures benefit from tokenization. By splitting text into smaller parts, following processing steps can treat each token separately, collecting valuable information and patterns. Our brains work hard to understand speech and written text, helping us make sense of the world. Natural language understanding is complicated, and seems like magic, because natural language is complicated. A clear example of this is the sentence “the trophy would not fit in the brown suitcase because it was too big.” You probably understood immediately what was too big, but this is really difficult for a computer. These examples are a small percentage of all the uses for natural language understanding.

NLU-enabled technology will be needed to get the most out of this information, and save you time, money and energy to respond in a way that consumers will appreciate. Using our example, an unsophisticated software tool could respond by showing data for all types of transport, and display timetable information rather than links for purchasing tickets. Without being able to infer intent accurately, the user won’t get the response they’re looking for. Without a strong relational model, the resulting response isn’t likely to be what the user intends to find. The key aim of any Natural Language Understanding-based tool is to respond appropriately to the input in a way that the user will understand. In this case, the person’s objective is to purchase tickets, and the ferry is the most likely form of travel as the campground is on an island.

Natural language generation (NLG) is a process within natural language processing that deals with creating text from data. At times, NLU is used in conjunction with NLP, ML (machine learning) and NLG to produce some very powerful, customised solutions for businesses. It is characterized by a typical syntactic structure found in the majority of inputs corresponding to the same objective.

Definition & principles of natural language processing (NLP)

This allows us to resolve tasks such as content analysis, topic modeling, machine translation, and question answering at volumes that would be impossible to achieve using human effort alone. 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.

NLU, on the other hand, is used to make sense of the identified components and interpret the meaning behind them.

Natural Language Understanding is also making things like Machine Translation possible. 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.
