This paper presents a novel method to extract the collocations of the Persian language using a parallel corpus. The method is applicable having a parallel corpus between a target language and any other high-resource one. Without the need for an accurate parser for the target side, it aims to parse the sentences to capture long distance collocations and to generate more precise results. A training data built by bootstrapping is also used to rank the candidates with a log-linear model. The method improves the precision and recall of collocation extraction by 5 and 3 percent respectively in comparison with the window-based statistical method in terms of being a Persian multi-word expression.
