On the basis of these, we then calculate the probability of a certain qualia ... paper presents an approach for the au- tomatic acquisition of qualia structures for nouns from the Web and thus opens the pos- sibility to explore the impact of qualia struc- tures for natural ... learning ranked qualia structures which allow to find an ideal cut-off point to increase the preci- sion/recall trade-off of the learned structures. We have abstracted from the issue of finding the...

Only 43 terms (20%) out of 210 terms were col- lected by the system. This low recall primarily comes from the ... explanation of the term. 4. There are several technical terms that are re- lated to the term. We have implemented the checking program of the first two conditions in the system: the thirdcondition can...

The lengths and frequency counts of the suffixes have been used to determine what is the translation ...
