ab: Summary: We present a resource-poor approach to automatically acquire
    Support Verb Constructions (SVCs) for European Portuguese with a
    two-stage procedure. First, we apply a cross-lingual approach with a
    bilingual parallel corpus: starting with a Portuguese full verb, we use
    the translations into another language and the corresponding
    backtranslations to identify Portuguese verb-noun pairs with the same
    meaning. Since not all of these are SVCs, the candidates are ranked and
    filtered in a second, monolingual step based on association statistics.
    We discuss two parametrisations of our procedure for a high-precision
    and a high-recall setting. In our experiments, these parametrisations
    achieve a maximum precision of 91\% and a maximum recall of 86\%,
    respectively.
