What is the need for separating analysis phase into lexical analysis and parsing?

∙ 6y ago
Separating the analysis phase into lexical analysis and parsing helps to break down the process of interpreting the structure of a source code into more manageable steps. Lexical analysis focuses on breaking the input into tokens, which are the smallest meaningful units, while parsing constructs a parse tree or syntax tree to represent the grammatical structure of the code. This separation allows for easier maintenance, testing, and implementation of new features in the compiler or interpreter.

Difference between lexical and semantic analysis?
Lexical analysis breaks the source code text into small pieces called tokens.Semantic analysis is the phase in which the compiler adds semantic information to the parse tree and builds the symbol table.Source: http://en.wikipedia.org/wiki/Semantic_analysis_%28compilers%29#Front_end
State one reason why chromography is very effective for this type of analysis?
What type of analysis? Chromatography is the separation of molecules based on how they react in a passing mobile phase through a stationary phase and separating the molecules.

anaphase I
What is different between analysis phase and synthesis phase?
synthesis phase synthesises while analysis phase analyses
What is lexical analysis?
A compiler is usually divided into different phases. The input to the compiler is the source program and the output is a target program. Lexical analyzer is the first phase of a compiler which gets source program as input. It scans the source program from left to right and produces tokens as output. A token can be seen as a sequence of characters having a collective meaning. Lexical analyzer also called by names like scanner, linear analyzer etc.
Is there any difference between requirement and analysis phase in software development life cycle?
Yes, there is different between requirement and analysis phases. In Requirement phase requirements are gathered and in analysis phase gathered requirements are analysed.
What is syntactic processing in AI?
The third phase of NLP is syntactic AI document processing, sometimes known as parsing or syntax analysis. The goal of this step is to extract precise, or dictionary-like, meaning from the text. Syntactic analysis is the process of assigning a semantic structure to text. It's also known as parsing or syntax analysis. Although both phrases include the same words, only the first is syntactically valid and comprehensible. Syntactic analysis is described as the process of determining the logical meaning of sentences or sections of sentences. The structure of phrases and the relationships between words within the phrase is referred to as syntax. The set of rules, concepts, and procedures that regulate the form of sentences in a natural language is referred to as syntax.
