How to find multi-word expressions in corpora

In the talk I will present automatic methods for finding some types of multi-word expressions in corpora. I will present a very simple typology of multi-word expressions based on some standard properties like fixedness or discontinuity and show how these properties determine suitable ways for automatic identification of the respective multi-word expression in corpora. Special focus will be put on lexicographic applications where, unlike in the case of single-word units, mere frequency is not sufficient for generating multi-headword candidates and, again unlike in the case of single-word units, there are no widely recognized strategies for automatic identification of these multi-word candidates.
