... goal of the inference is to infer the value of the m variable corresponding to the root of the tree. All that is left to specify the full HIER model is to specify the probability distribution ... FLAT model considers these versions of German just as statisti- cally independent as, say, German and Hindi. To cope with this problem, we then augment the FLAT model into a HIERarc...

... thing to note is that our f link is not artificially weak. Our func- tion takes into account token pairs and position, making it roughly equivalent to IBM Model 2. Our weakest method outperforms Model ... 2001). There are three primary reasons to add syntax to word alignment. First, one can incorporate syntac- tic features, such as grammar productions, into the models that guide...

... model p 2 (e, f ) to deal with non-transliteration pairs (the “non-transliteration model ). Interpolation with the non-transliteration model allows the transliteration model to concentrate on modelling ... exploited to identify transliterations. In a non-transliteration word pair, the characters of the source and target words are unrelated. We model them as randomly seeing a...

... computationally infeasi- ble to directly use the feature vector ()T φ . To solve this computational issue, Collins and Duffy (2001) proposed the following parse tree kernel to calculate the dot product ... by layer in a top- down manner. Culotta and Sorensen (2004) gen- eralized it to estimate similarity between depend- ency trees. Their tree kernels require the match- able nodes t...

A related problem is word sense disambiguation: Here the senses are assu...
