In computer science, a directed acyclic word graph (DAWG) is a data structure that represents the set of all substrings of a string. As its name implies, a DAWG takes the form of a directed acyclic graph; it can also be viewed as a deterministic finite automaton, and is similar in structure to suffix trees. DAWG have applications in approximate string matching.[1]
