Partial derivatives of regular expressions and finite automaton constructions

V Antimirov - Theoretical Computer Science, 1996 - Elsevier
We introduce a notion of partial derivative of a regular expression and apply it to finite
automaton constructions. The notion is a generalization of the known notion of word …

Incremental construction of minimal acyclic finite-state automata

J Daciuk, S Mihov, BW Watson… - Computational linguistics, 2000 - direct.mit.edu
In this paper, we describe a new method for constructing minimal, deterministic, acyclic finite-
state automata from a set of strings. Traditional methods consist of two phases: the first to …

Processing XML streams with deterministic automata and stream indexes

TJ Green, A Gupta, G Miklau, M Onizuka… - ACM Transactions on …, 2004 - dl.acm.org
We consider the problem of evaluating a large number of XPath expressions on a stream of
XML packets. We contribute two novel techniques. The first is to use a single Deterministic …
