enDescription
Automatic identification of Multiword Expressions (MWEs) in running text has recently received much attention among researchers in computational linguistics. The wide range of reported results for the task in the literature has prompted us to take a closer look at the algorithms and evaluation methods. For supervised classification of Verb+Noun expressions, we propose a context-based methodology in which we find word embeddings to be appropriate features. We discuss the importance of train and test splitting in validating the results and present type-aware train and test splitting. Given our specialised data, we also discuss the benefits of framing the task as classification rather than tagging.ISBN
