In the dative alternation in English, speakers and writers choose between the prepositional dative construction (‘I gave the ball to him’ and the double object construction (‘I gave him the ball’). Logistic regression models have already been shown to be able to predict over 90% of the choices correctly (e.g. Bresnan et al. 2007).
Collecting dative instances from a corpus and encoding them with the required information is a costly procedure. We therefore developed a semi-automatic approach to do this, consisting of three steps: (1) automatically extracting dative candidates, (2) manually approving or rejecting these candidates, and (3) automatically annotating the approved candidates with the required information. The resulting data sets are noisier than data sets that have been checked completely manually, but the approach can yield much larger data sets.
We compare the effect of data set size and noisiness on the accuracy of predicting the dative alternation. We employ a ‘manual’ set of 2,877 instances in spoken English, taken from Switchboard (Godfrey et al. 1992) by Bresnan et al (2007) and from ICE-GB (Greenbaum 1996) by Theijssen (2010). In addition, we use a ‘semi-automatic’ set with 7,755 instances from Switchboard, ICE-GB and BNC (BNC Consortium 2007). We compare the learning curves of various machine learning algorithms by randomly selecting subsets of the data and extending them with 500 instances each time. We do this for different levels of noisiness, i.e. varying the proportion of ‘semi-automatic’ instances (0%, 25%, 50%, 75%, 100%). The results are presented at the conference.
