... derived gold standard annotations for all the examples in the Senseval- 3 training section for our 25 target words. For the test set we took up to 40 test examples for each tar- get word (some words ... approach The indirect approach for sense matching fol- lows the traditional scheme of performing WSD for lexical substitution. First, the WSD classifier described above was trained...

... precompiling additional information, parsing can be broken down into recognition followed by parse recovery; • providing a formal treatment of the algo- rithms for transforming and minimising ... annotations are unioned; • the parser maintains for each item in the table the set of trees that are valid for the item: initially this is all the valid trees for the automaton, but...

... it is well-formed or ill-formed. • maximal iff it is well-formed and its parent (if it has one) is ill-formed. In other words, a maxi- mal TNCB is a largest well-formed component of a TNCB. ... permutation of signs is input to a shift-reduce parser which tests them for grammatical well-formedness. If they are well-formed, the system halts indicating success. If not, another permutat...

... ABCG2 R482G isoform was examined in the nucleotide-bound and post-hydrolytic conformations. Binding of [ 3 H]daunomycin was displaced by ATP analogues, indicating transition to a low-affinity conformation ... post-hydrolysis. Therefore, the dissoci- ation of phosphate and ⁄ or ADP is likely to be responsible for resetting of the transporter. The data indicate that, like ABCB1 and ABCC1, the...
