AbstractThis paper examines a common design for a lexical analyser and its supporting modules. An implementation of the design was tuned to produce the best possible performance. In effect, many of the optimizations that one would expect of a production‐quality compiler were carried out by hand. After measuring the cost of tokenizing two large programs

ACM SIGPLAN Notices, 2004
This paper provides an algorithm for constructing a lexical analysis tool, by different means than the UNIX Lex tool. The input is a keywords table, describing the target language's keywords, keysymbols, and their semantics, instead of using regular expressions to do so.The output is a lexical analyzer for the specific programming language.

Multiple Input Parsing and Lexical Analysis
ACM Transactions on Programming Languages and Systems, 2023This article introduces two new approaches in the areas of lexical analysis and context-free parsing. We present an extension, MGLL, of generalised parsing which allows multiple input strings to be parsed together efficiently, and we present an enhanced approach to lexical analysis which exploits this multiple parsing capability.

A lexically based, corpus-driven theoretical approach to meaning in language that distinguishes between patterns of normal use and creative exploitations of norms. In Lexical Analysis, Patrick Hanks offers a wide-ranging empirical investigation of word use and meaning in language.

This paper presents the development and verification of a (very simple) lexical analyzer generator that takes a regular expression and yields a functional lexical analyzer. The emphasis is on simplicity and executability. The work was carried out with the help of the theorem prover Isabelle/HOL.

The lexical analysis of French
1989The automatic linguistic analysis of texts requires basic information about the simple and compound words of the text. Lexical analysis is the preliminary step before syntactic analysis. We have shown that important linguistic problems appear during this basic step.

An exploration on lexical analysis
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016The word lexical in lexical analysis, its meaning is extracted from the word “lexeme”. Lexeme is an abstract unit of morphological analysis in linguistics. A lexical analyser is used in various applications like text editors, information retrieval system, pattern recognition programs and language compilers.

Lexical Characterization and Analysis of the BioPortal Ontologies
2013The increasing interest of the biomedical community in ontologies can be exemplified by the availability of hundreds of biomedical ontologies and controlled vocabularies, and by the international recommendations and efforts that suggest ontologies should play a critical role in the achievement of semantic interoperability in healthcare.

A Doubly Projected Analysis for Lexical Tables
2009This chapter aims to show how external information contributes in analysing a lexical table by enriching the readability of factorial maps. The theoretical frame is given by principal component analysis onto a reference subspace, a method based on the orthogonal projection of a correlation structure on the space spanned by an external set of ...

A lexical analysis of environmental sound categories.
Journal of Experimental Psychology: Applied, 2012In this article we report on listener categorization of meaningful environmental sounds. A starting point for this study was the phenomenological taxonomy proposed by Gaver (1993b). In the first experimental study, 15 participants classified 60 environmental sounds and indicated the properties shared by the sounds in each class.
