A compiler is likely to perform many or all of the following operations: lexical analysis, preprocessing, parsing, semantic analysis ( Syntax-directed translation ), code generation, and code optimization.
Determining an instance of the membership problem ; i. e. given a string, determine whether where is the language generated by some grammar ; is also known as parsing.
Modern methods include the use of lossless data compression for incremental parsing, prediction suffix tree and string searching by factor oracle algorithm ( basically a factor oracle is a finite state automaton constructed in linear time and space in an incremental fashion ).
If the XML document type declaration includes any SYSTEM identifier for the external subset, it can't be safely processed as standalone: the URI should be retrieved, otherwise there may be unknown named character entities whose definition may be needed to correctly parse the effective XML syntax in the internal subset or in the document body ( the XML syntax parsing is normally performed after the substitution of all named entities, excluding the five entities that are predefined in XML and that are implicitly substituted after parsing the XML document into lexical tokens ).

In computer science, the Cocke – Younger – Kasami ( CYK ) algorithm ( alternatively called CKY ) is a parsing algorithm for context-free grammars.
Using Landau symbols, the worst case running time of CYK is, where n is the length of the parsed string and | G | is the size of the CNF grammar G. This makes it one of the most efficient parsing algorithms in terms of worst-case asymptotic complexity, although other algorithms exist with better average running time in many practical scenarios.
