• Semantics is about the meaning of words, phrases, and sentences. It looks at how we understand and interpret
                these meanings when we use language. For example, the word “bat” can have different meanings depending
                on the context of a sentence. A bat can refer to a flying mammal (the animal). A bat can also refer to a piece
                of equipment used in sports like baseball or cricket.

                     1.  Differentiate between syntax and semantics.


                     2.  Name the language used by computers to work.






              Multiple Meanings of the Words

              English is one of the natural languages used to communicate. It has words which can have multiple meanings and
              different meaning fits into the statement according to its context.
              For example,
                 • His future is very bright.

                 • Today, the Sun is very bright.
              In the above sentences the word "bright" is playing a different role. This kind of situation can be easily handled by
              humans using their intelligence and language skills. However, teaching a computer to understand and interact in
              human language is a very challenging task. Now, let us study how Natural Language Processing makes it possible
              for the machines to understand and speak in the Natural Languages just like humans.

              Features of Natural Languages


              Natural languages have the following key features:
                 • They are governed by set rules that include syntax, lexicon, and semantics.
                 • All natural languages are redundant, i.e., the information can be conveyed in multiple ways.
                 • All natural languages change over time.
