Presents abstract models of computers (finite automata, pushdown automata and Turing machines) and the language classes they recognize or generate (regular, context-free and recursively enumerable). A regular expression is compiled into a recognizer by constructing a generalized transition diagram called a Finite Automaton (FA). including NFA (Non-deterministic Finite Automata) and DFA (Deterministic Finite Auto-. We define some benchmarking criteria for measuring the usability of annotation tools, and examine those factors which are particularly important for a real user to be able to determine which is the most suitable tool for their use. The finite state automata (FSA) theory is an essential tool used in many areas in computer science, including pattern matching, database, and compiler technology.
