👉 A parser is a computer program that reads input, processes it according to its rules and constructs a specified output. It can be used in various applications such as natural language processing, speech recognition, and automated theorem proving.
The primary function of a parser is to identify and extract information from the input text or other data streams. This process involves several steps:
1.
Tokenization
: Dividing the input into individual tokens (words) based on their syntactic properties.
2.
Parse Tree Construction
