A Wordnet from the Ground Up

4.5. Hybrid Combinations 159Figure 4.12:A correct WNW decision made for karafka ‘carafe’ on the evidence collected from thecontext. Glosses: pojemnik ‘container’, naczynie ‘pot = utensil’, naczynie sanitarne ‘sanitarypot’, naczynie gospodarcze ‘household container’, butelka, flaszka, szkło ‘bottle, bottle,(glass) bottle’, butelka, butla ‘baby bottle’, kryształ ‘crystal (container)’, naczynie stołowe‘tableware’, szklanka ‘glass = container’The last example (Figure 4.16) illustrates the problems that the present version ofWNW has with Polish gerunds. Their specific syntactic behaviour prevents the MSRextraction method and the patterns from producing good results. We plan to work ona dedicated solution. Figure 4.16 is also an honest admission that WNW is sometimesnot helpful for linguists, but at any moment they can switch to completely manualediting of the plWordNet database for any new lemma.In the following points we investigate the statistical measures of WNW’s accuracy.Analysis of the linguist’s workWNW stores information on the linguist’s every decision. For positive decisions, theapplication records the distance along hyponymy/hypernymy links between the pointof attachment and the proposed attachment centre, plus a possible linguist’s comment.For negative decisions, the linguist is asked for the error type and its possible cause.Seven error types include such situations as a tagging error or an unlisted sense thatthe linguist has to add manually.
