NLU or Natural Language Understanding is a subfield of Artificial Intelligence (AI) that focuses on the interaction between humans and computers using natural language. The ultimate objective of NLU is to read, decipher, understand, and make sense of the human language in a valuable way.
NLU is used in many everyday applications. For instance, virtual assistants like Siri, Alexa, and Google Assistant use NLU to understand and respond to voice commands. Email filters use NLU to filter out spam. Additionally, NLU is used in text analysis, sentiment analysis, and machine translation.
While both NLP (Natural Language Processing) and NLU work with human language, NLP is more about the processing and analysis of language data, while NLU is about understanding the meaning and intention behind this data.
NLU works by applying algorithms to identify and extract the natural language rules. This allows the system to understand the full meaning of the text, including the sentiment and intent.
Some of the popular software that leverage NLU include IBM Watson, Google's Natural Language API, and Amazon Lex.
NLU allows computers to communicate with people in their own language, eliminating the need for a specialized computer language. It also helps in analyzing social media sentiment, enhancing customer service, and improving accessibility through voice-activated systems.
In conclusion, NLU is a crucial component of AI technology that enables a more natural and intuitive interaction between humans and computers. It is an ever-evolving field with immense potential for future applications.
