Parsing may be divided into parts: lexical analysis and semantic parsing. Lexical analysis divides strings into components based on punctuation or tagging. Semantic parsing then attempts to determine the meaning of the string.
Analysis, intended for use by NL (natural language) parsing researchers and others interested in the automated extraction of Chess data from text articles. A more complete usage requires actual game parsing. After reading the game, a parse_game() method is called, and as a result we have the moves available in an array, comments and errors in two hashes, where the keys are the move numbers and the values are comments or errors .
We say that certain Emacs commands parse words or expressions in the text being edited. Really, all they know how to do is find the other end of a word or expression. See section AD.6 The Syntax Table.
In computer science and linguistics, parsing (more formally syntax analysis) is the process of analyzing a sequence of tokens to determine its grammatical structure with respect to a given formal grammar. A parser is a computer program that carries out this task, it a component of a compiler.
An SGML parser is a computer application that breaks down an SGML-coded document into a series of logical elements and checks that these elements conform to the model defined in the associated document type declaration. When parsing a document, the SGML parser: Checks each new character to see if it is part of a general delimiter string that identifies the start of a piece of markup. Checks whether or not the character is a short reference delimiter that needs to be expanded. Checks if the character is a separator character that should be ignored. Identifies the various markup tags, identifying any entities that need to be expanded or recalled from external sources. Checks if identified markup tags are valid according to the declared model.
When a computer program examines a set of values, and breaks it into fields, words or commands based on some separator. A spell checker program parses the words to check by looking for spaces and punctuation.
The process of checking an SGML formatted document to ensure it has met all the rules of both SGML and the DTD that is being used. Technically, a document is not considered to be SGML until it has been successfully parsed, as defined by the ISO Standard for SGML.
The breakdown of a field into its components. For instance, our Address Correction software parses the address into its distinct components: ZIP code, city, state, house number, street name, and so on.
