* Bottom-up parsing

Bottom-up parsing is a strategy for analyzing unknown data relationships that attempts to identify the most fundamental units first, and then to infer higher-order structures from them.

Bottom-up parsing lazily waits until it has scanned and parsed all parts of some construct before committing to what the combined construct is.

Bottom-up processes are generally driven by the abiotic conditions required for primary producers to grow, such as availability of light and nutrients, and the subsequent transfer of energy to consumers at higher trophic levels.

" Bottom-up " ( or " small chunk ") cognition is akin to focusing on the detail primarily, rather than the landscape.

Bottom-up emphasizes coding and early testing, which can begin as soon as the first module has been specified.

* Bottom-up approach: Once we formulate the solution to a problem recursively as in terms of its subproblems, we can try reformulating the problem in a bottom-up fashion: try solving the subproblems first and use their solutions to build-on and arrive at solutions to bigger subproblems.

Bottom-up processing is a type of information processing based on incoming data from the environment to form a perception.

Bottom-up approaches seek to have smaller ( usually molecular ) components built up into more complex assemblies, while top-down approaches seek to create nanoscale devices by using larger, externally controlled ones to direct their assembly.

Bottom-up approaches, in contrast, use the chemical properties of single molecules to cause single-molecule components to ( a ) self-organize or self-assemble into some useful conformation, or ( b ) rely on positional assembly.

* Integrated Parallel Bottom-up and Top-down Approach.

* Bottom-up parsing-A parser can start with the input and attempt to rewrite it to the start symbol.

* Bottom-up models are often the result of a reengineering effort.

Bottom-up approaches, in contrast, use the chemical properties of single molecules to cause single-molecule components to ( a ) self-organize or self-assemble into some useful conformation, or ( b ) rely on positional assembly.

Bottom-up input arrives at layer 4 ( L4 ), whence it propagates to L2 and L3 for recognition of the invariant content.

Bottom-up effects occur when the population density of a resource affects the population of the resources ’ consumer.

Objective Elaboration: Bottom-up thinking in which facts are scrutinized without bias ; seeking truth wherever it might lead.

Shallow parsing ( also chunking, " light parsing ") is an analysis of a sentence which identifies the constituents ( noun groups, verbs, verb groups, etc.

In an object pipeline, the processes output objects instead of texts ; therefore removing the string parsing tasks that are common in UNIX shell scripts.

Lexical preprocessors are the lowest-level of preprocessors, in so far as they only require lexical analysis, that is, they operate on the source text, prior to any parsing, by performing simple substitution of tokenized character sequences for other tokenized character sequences, according to user-defined rules.

For some advocates of whole language, phonics was antithetical to helping new readers to get the meaning ; they asserted that parsing words into small chunks and reassembling them had no connection to the ideas the author wanted to convey.

When the compiler runs, those data tables are used by a small, language-independent parsing algorithm to parse and respond to the input language.

* xpdev is a cross platform development library which provides such features as threading,. ini file parsing, consistent * printf () functions, and other small utility functions to the rest of the project.

There are also hybrid approaches ( e. g., VTD-XML ) that attach a small index file to an XML document to eliminate the overhead of parsing.

The abstraction can entail the removal of details which are relevant only in parsing, not for semantics.

He is scrupuluously attentive to details, recording the possible positions of his arms and legs in the Progress and Advice Room ; making note of who was on top first, or on which shoulder he was bitten, and which brand of condoms were used in his affair with Rennie ; even parsing the grammar of sentences for the reader.

The first attempt to solve this problem were the memory optimizations introduced in 1977 by D. Pager but still the LR parser required significantly more memory than other parsing methods.

Additionally, Tullus Hostilius ' warlike and ferocious character seems be little more than a contrasting stereotype to the peaceable, devout Numa Pompilius ; the first Roman annalists may merely have imputed aggressive qualities to Hostilius by naively parsing his gentile name ( Hostilius meaning " hostile " in Latin ).

In computer science, top-down parsing is a parsing strategy where one first looks at the highest level of the parse tree and works down the parse tree by using the rewriting rules of a formal grammar.

In this way the parsing starts on the Left of the result side ( right side ) of the production rule and evaluates non-terminals from the Left first and, thus, proceeds down the parse tree for each new non-terminal before continuing to the next symbol for a production rule.

This is because they have transferred their parsing preference from their first language English to their second language German.

He is known for designing and implementing the REXX programming language ( published in IBM Systems Journal in 1984 ) and the NetRexx programming language ( 1996 – 1997 ), his work on color perception and image processing ( 1982 – 1985 ), the STET folding editor ( 1977 ), the LEXX live parsing editor ( 1985, possibly the first editor with color highlighting ) for the Oxford English Dictionary, electronic publishing, SGML applications, PMGlobe, the IBM Jargon file ( IBMJARG ) through 1990, Java-related languages, the Acorn System 1 simulator,

The ' o ' command does the same for the output base, but keep in mind that the input base will affect the parsing of every numeric value afterwards so it is usually advisable to set the output base first.

In computer science, parsing reveals the grammatical structure of linear input text, as a first step in working out its meaning.

An atomic parsing expression consisting of a single terminal ( i. e. literal ) succeeds if the first character of the input string matches that terminal, and in that case consumes the input character ; otherwise the expression yields a failure result.

With some modification, traditional packrat parsing can support direct left recursion, but doing so results in a loss of the linear-time parsing property which is generally the justification for using PEGs and packrat parsing in the first place.

*" Time flies like an arrow ; fruit flies like a banana " is an example of a garden path sentence-the first half of the sentence misleads the reader into parsing the second half incorrectly.

This was the first version to use the project's HTML5 parsing library, Hubbub.

This was the first release to use the project's library for CSS parsing and selection, LibCSS and a new internal cache for fetched content.

The first automatic system for Semantic Role Labeling ( SRL, sometimes also referred to as " shallow semantic parsing ") was developed by Daniel Gildea and Daniel Jurafsky based on FrameNet in 2002, and Semantic Role Labelling has since become one of the standard tasks in natural language processing.
