The GIZA++ and HM-BiTAM with the SRH slightly outperformed the standard GIZA++ ... alignment model. We formulate a syn- onym pair generative model with a topic variable and use this model as a regularization term with a bilingual word alignment model. The topic vari- able...

... text. To begin with, we preprocess each document. A training text is preprocessed by ran- domly replacing 10% of its common nouns with the label UNSEEN. If an NP, NP k , is replaced with UN- SEEN, ... employ different methods to extract NPs from the documents anno- tated with the two annotation schemes. To extract NPs from the ACE-annotated docu- ments, we train a mention extractor on...

With this approach, one would need to collect a text cor- pus, in which each ambiguous word occurrence is first tagged with its correct sense to serve ... with a naive Bayes classifier, the sense s assigned to an example with features f 1 , . . . , f n is chosen so as to maximize: p(s) n  j=1 p(f j |s) In our domain adaptation study, we s...

The PCR product with a size of  1.6 kb was digested with BamHI to obtain a fragment between the two copper-binding site coding regions and ligated to pBlueScript pKSII(+) with T4 DNA ligase ...

... rows report the cross-pair similarity carried out with Eq. 6 with (Synt Trees with placeholders) and without (Only Synt Trees) augmenting the trees with placehold- ers, respectively. Each column ... After substituting 3 with b and 2 with a , we can detect if T 1 and T 3 share the bold subtree S → NP 2 VP 3 . As such subtree is shared also by H 1 and H 3 , the words within the pair...
