This paper discusses the use of statistical word alignment over multiple parallel texts for the identi- fication of string spans that cannot be constituents in one of the languages. This information is ex- ploited in monolingual PCFG grammar induction for that language, within an augmented version of the inside-outside algorithm. Besides the aligned corpus, no other resources are required. We discuss an implemented system and present experimental results with an evaluation against the Penn Tree- bank.
