Why is the use of lexicon crucial in computational linguistics and natural language processing?

The use of lexicon is very important when talking about computers and language. This is because when people talk or write using a language, they use many different words and terms to express their ideas. A lexicon is like a big dictionary that tells the computer what each word means and how to use it. Without a lexicon, the computer would not understand what we are trying to say.

There are many different applications of natural language processing where the use of a lexicon is crucial. For example, when we talk to Siri or Alexa, we are actually using natural language processing. We ask our question or make a request, and the computer tries to understand what we are saying. The lexicon helps the computer understand what we mean and how to respond to us.

Another application of natural language processing is sentiment analysis. This is when the computer tries to understand if what we are saying is positive or negative. For example, if we say "I love this restaurant", the computer needs to understand that we have a positive opinion of the restaurant. A lexicon helps the computer understand which words are positive or negative, and this makes it easier for the computer to understand our sentiment.

Finally, a lexicon is also important when trying to develop new languages. When people create new languages, they need to create a lexicon that tells the computer how to understand and interpret the new language. This is important because without a lexicon, the computer would not be able to understand the new language.

In conclusion, the use of a lexicon in computational linguistics and natural language processing is very important. A lexicon is like a dictionary that helps the computer understand what we are saying and how we mean it. It is important to have a lexicon so that computers can understand us better and respond to our requests more accurately.
