It is well known that parsing accuracy suf- fers when a model is applied to out-of-domain data. It is also known that the most benefi- cial data to parse a given domain is data that matches the domain (Sekine, 1997; Gildea, 2001). Hence, an important task is to select appropriate domains. However, most previ- ous work on domain adaptation relied on the implicit assumption that domains are some- how given. As more and more data becomes available, automatic ways to select data that is beneficial for a new (unknown) target domain are becoming attractive. This paper evaluates various ways to automatically acquire related training data for a given test set. The results show that an unsupervised technique based on topic models is effective – it outperforms ran- dom data selection on both langu...
