... general, computational studies of transliteration fall into two categories: transliteration modeling and extraction of transliteration pairs. In transliteration modeling, transliteration rules are ... jskuo@cht.com.tw 120 Unfortunately, most of the reported work in the area of machine transliteration has not ventured into semantic transliteration yet. The Latin-scr...

Over the set of 5 semantic rela- tions defined by Nastase and Szpakowicz (2003), they achieve an accuracy of 45.7% for the task of assigning one of 5 semantic relations to each of the 600 modifier-noun ... in this paper was twofold.

Section 5 gives an example of such a grammar designed for the purpose of automatic tagging of queries. Sectio...

... Background As part of our research on definite description (DD) interpretation, we asked 3 subjects to classify the uses of DDs in a corpus using a taxonomy related to the proposals of (Hawkins, ... DDs) found a total of 240 relations, dis- tributed over 107 cases of DDs. There were 54 cor- rect resolutions (distributed over 34 DDs) and 186 false positives. Types of bridg...

Each of these four questions is addressed in the four subsequent sections of this paper, fol- lowed by a discussion of the implications of our findings ... harmonic mean of precision and recall. Our calculation of recall scores represents the best-possible performance of systems using only these types of parse-tree paths....
