Abstract

A text is a word together with an additional linear order on it. We study quantitative models for texts, i. e. text series which assign to texts elements of a semiring. We consider an algebraic notion of recognizability following Reutenauer and Bozapalidis and show that recognizable text series coincide with text series definable in weighted logics as introduced by Droste and Gastin. In order to do so, we study certain definable transductions and show that they are compatible with weighted logics. Moreover, we show that the behavior of weighted parenthesizing automata coincides with certain definable series.
