Compilation - Part Three: Syntax Analysis
This is part three of a series of videos about compilation. Part three is about syntax analysis. It explains how the syntax analyser, otherwise known as the parser, takes a token stream from the lexical analyser, and checks it to make sure that the rules of the source language have been followed correctly. This video begins by describing a simple context free grammar and illustrates how the grammar of a high level programming language can be accurately described, and communicated between programmers, using a notation such as Backus-Naur Form (BNF). The video goes on to explain how the syntax of a source program can be checked by constructing a parse tree, and how this can be refined to an abstract syntax tree to allow for more detailed semantic analysis. The representation of arithmetic expressions using infix, prefix and postfix notations is covered, along with expression trees and directed acyclic graphs (DAG). As you will see when you watch this series, compilation involves a diverse range of themes in the field of computer science including high and low level programming paradigms, the definition of context free grammars, the application of dynamic data structures such as stacks, linked lists, hash tables, graphs and trees, memory management, processor architectures, and more. This series will give you an insight into some of the concepts and features that are typical of many compilers.

What is LEXICAL APPROACH? What does LEXICAL APPROACH mean? LEXICAL APPROACH meaning & explanation
What is LEXICAL APPROACH? What does LEXICAL APPROACH mean? LEXICAL APPROACH meaning - LEXICAL APPROACH definition - LEXICAL APPROACH explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ The lexical approach is a method of teaching foreign languages described by Michael Lewis in the early 1990s. The basic concept on which this approach rests is the idea that an important part of learning a language consists of being able to understand and produce lexical phrases as chunks. Students are thought to be able to perceive patterns of language (grammar) as well as have meaningful set uses of words at their disposal when they are taught in this way. In the lexical approach, instruction focuses on fixed expressions that occur frequently in dialogues, which Lewis claims make up a larger part of discourse than unique phrases and sentences. Vocabulary is prized over grammar per se in this approach. The teaching of chunks and set phrases has become common in English as a foreign or second language, though this is not necessarily primarily due to the Lexical Approach. The lexical syllabus is a form of the propositional paradigm that takes 'word' as the unit of analysis and content for syllabus design. Various vocabulary selection studies can be traced back to the 1920s and 1930s (West 1926; Ogden 1930; Faucet et al. 1936), and recent advances in techniques for the computer analysis of large databases of authentic text have helped to resuscitate this line of work. The modern lexical syllabus is discussed in Sinclair & Renouf (1988), who state that the main benefit of a lexical syllabus is that it emphasises utility - the student learns that which is most valuable because it is most frequent. Related work on collocation is reported by Sinclair (1987) and Kennedy (1989), and the Collins COBUILD English Course (Willis & Willis 1988) is cited as an exemplary pedagogic implementation of the work, though "in fact, however, the COBUILD textbooks utilise one of the more complex hybrid syllabi in current ESL texts" (Long & Crookes 1993:23). Sinclair & Renouf (1988:155) find that (as with other synthetic syllabi), claims made for the lexical syllabus are not supported by evidence, and the assertion that the lexical syllabus is "an independent syllabus, unrelated by any principles to any methodology" (Sinclair et al. 1988:155) is subject to the criticism levelled by Brumfit against notional functional syllabi, i.e. that it (in this case, deliberately) takes no cognisance of how a second language is learned. Since these observations were made, however, Willis (1990) and Lewis (1993) have gone some way to provide such a theoretical justification.

3.1| Lexical Analysis - Compilers and interpreters 12m06s
Compilers and interpreters [Stanford University] ====================================== This course will discuss the major ideas used today in the implementation of programming language compilers, including lexical analysis, parsing, syntax-directed translation, abstract syntax trees, types and type checking, intermediate languages, data flow analysis, program optimization, code generation, and run time systems. As a result, you will learn how a program written in a high-level language designed for humans is systematically translated into a program written in low-level assembly more suited to machines. Along the way we will also touch on how programming languages are designed, programming language semantics, and why there are so many different kinds of programming languages. The course lectures will be presented in short videos. To help you master the material, there will be in-lecture questions to answer, quizzes, and two exams: a midterm and a final. There will also be homework in the form of exercises that ask you to show a sequence of logical steps needed to derive a specific result, such as the sequence of steps a type checker would perform to type check a piece of code, or the sequence of steps a parser would perform to parse an input string. This checking technology is the result of ongoing research at Stanford into developing innovative tools for education, and we're excited to be the first course ever to make it available to students. An optional course project is to write a complete compiler for COOL, the Classroom Object Oriented Language. COOL has the essential features of a realistic programming language, but is small and simple enough that it can be implemented in a few thousand lines of code. Students who choose to do the project can implement it in either C++ or Java. Why Study Compilers? Everything that computers do is the result of some program, and all of the millions of programs in the world are written in one of the many thousands of programming languages that have been developed over the last 60 years. Designing and implementing a programming language turns out to be difficult; some of the best minds in computer science have thought about the problems involved and contributed beautiful and deep results. Learning something about compilers will show you the interplay of theory and practice in computer science, especially how powerful general ideas combined with engineering insight can lead to practical solutions to very hard problems. Knowing how a compiler works will also make you a better programmer and increase your ability to learn new programming languages quickly. enjoy it!

Lexical Analysis in Regular Expressions
Lexical analysis is the first phase of a compiler. It takes the modified source code from language preprocessors that are written in the form of sentences. The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code. If the lexical analyzer finds a token invalid, it generates an error. The lexical analyzer works closely with the syntax analyzer. It reads character streams from the source code, checks for legal tokens, and passes the data to the syntax analyzer when it demands.

When we talk about syntax, we also consider the analysis of phrases and sentences. EARLIER & MODERN SYNTAX APPROACHES: In earlier approaches to syntax, the focus was to produce a linear sentence, with accuracy and specific sequence of words and phrases as in traditional analysis. In recent approaches, the focus is on the "underlying" rule system in a language which enables us to produce or generate a lot of sentences. THINGS TO KEEP IN MIND WHILE SYNTACTIC ANALYSIS: 1. All and only criterion. 2. One must pick only those sentences and phrases which are grammatically correct. 3. If make rules, then should be carefully invent, that when these rules are applied logically, should not produce ill-formed phrases and sentences. For example it is more appropriate to say that pronouns replace noun phrases not only nouns and a preposition or prepositional phrase follow a noun phrase. GENERATIVE GRAMMAR: A concept by Noam Chomsky i.e. we have a finite set of rules in language through which we are able to produce infinite sentences. It means when we discover or invent the underlying rule system of forming a sentence or phrase such as two effective rules we discussed above. With these rules we can produce infinite number of prepositional phrases and we can replace infinite number of noun phrases or nouns with pronouns.

Natural Language Processing With Python and NLTK p.1 Tokenizing words and Sentences
Natural Language Processing is the task we give computers to read and understand (process) written text (natural language). By far, the most popular toolkit or API to do natural language processing is the Natural Language Toolkit for the Python programming language. The NLTK module comes packed full of everything from trained algorithms to identify parts of speech to unsupervised machine learning algorithms to help you train your own machine to understand a specific bit of text. NLTK also comes with a large corpora of data sets containing things like chat logs, movie reviews, journals, and much more! Bottom line, if you're going to be doing natural language processing, you should definitely look into NLTK!
