From WordNet (r) 3.0 (2006) :

      n 1: a computer program that divides code up into functional
           components; "compilers must parse source code in order to
           translate it into object code"

From The Free On-line Dictionary of Computing (18 March 2015) :

      An algorithm or program to determine the
     syntactic structure of ("parse") a sentence or string of
     symbols in some language.  A parser normally takes as input a
     sequence of tokens output by a lexical analyser.  It may
     produce some kind of abstract syntax tree as output.  A
     parser may be produced automatically from a grammar by a
     parser generators such as yacc.
     A parser is normally part of some larger program, like a
     compiler, which takes the output of the parser and attempts
     to extract meaning from it in some way, e.g. translating it
     into another language.
