PermA and Balloon: Tools for string alignment and text processing

摘要

Two online research tools are presented in this paper: PermA, a general-purpose string aligner which can for example be used for grapheme-to-phoneme and phoneme-to-phoneme alignment, and Balloon, a text processingtoolkit for German and English providing components for part-of-speech tagging, morphological analyses, and grapheme-to-phoneme conversion including syllabifica-tion and word-stress assignment. The general architectures of these tools are introduced with a focus on recent improvements concerning the alignment cost function derivation and word stress assignment.
