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.

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.

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 ...

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 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.

The Modern Language Journal, 1965
CURRENT pedagogical theory holds that language students have most difficulty learning those foreign language elements which differ most from their native language. Contrastive analysis (or contrastive grammar) seeks to catalogue, through the comparative analysis of the native and foreign language systems, the points of difference, so that more ...

Lexical Multidimensional Analysis
Lexical Multidimensional Analysis (LMDA), an extension of Biber's (1988) Multidimensional Analysis, seeks to identify dimensions (correlated lexical features across texts in a corpus) unveiling underlying patterns of lexical co-occurrence and variation within texts that are operationalized as a variety of latent, macro-level discursive constructs ...Tony Berber Sardinha +1 more

On the look-ahead problem in lexical analysis
Acta Informatica, 1995Modern programming languages use regular expressions to define valid tokens. Traditional lexical analyzers based on minimum deterministic finite automata for regular expressions cannot handle the look-ahead problem. The scanner writer needs to explicitly identify the look-ahead states and codes the buffering and re-scanning operations by hand.
