Space-time tradeoff in regular expression matching with semi-deterministic finite automata
Abstract—Regular expression matching (REM) with nondeterministic finite automata (NFA) can be computationally expensive when a large number of patterns are matched concurrently....

Temporal Support of Regular Expressions in Sequential Pattern Mining
Classic algorithms for sequential pattern discovery, return all frequent sequences present in a database. Since, in general, only a few ones are interesting from a user's poin...

XML Validation for Context-Free Grammars
String expression analysis conservatively approximates the possible string values generated by a program. We consider the validation of a context-free grammar obtained by the analy...
