... investigate named entity transliteration based on a phonetic scoring method. The phonetic method is computed using phonetic features and carefully designed pseudo features. The proposed method ... based on the distinctive features and pseudo features, based on the pure linguistic knowledge without training data. As illustrated in Table 7, the phonetic transliteration...

... and semantics. We also show, for each feature, the types of the values that it takes; as it happens, these are all disjunctive. So, for example, the feature seman- tics has a value either ... universal quantification over features. This device offers a way of characterizing the well-formedness of dif- ferent dimensions of a sign that is stronger than systems based on open types,...

We then trained and tested models using ... one synonym. If there is a syn- onym match, we use synonym-matching features. 3.3 Dependency matching features The same sorts of features are produced whether there is a “morph-or-mention” m...
