... the algorithms and by not subdividing the training words in word classes. 4 Generation of rules and look-up data structure 4.1 Building a rule set from training pairs The training algorithm ... one of the remaining candidates instead. The training pairs that are matched by the pat-tern of the winning rule become the supporters and non-supporters of that new rule and are no longer ... schemes and thus a finite number of lemmatization rules should suffice to lemmatize indefinitely many words. In agglutinated languages, on the other hand, there are classes of words that in principle...

... Automatic Detection of Grammar Elements that Decrease ReadabilityMasatoshi Tsuchiya and Satoshi SatoDepartment of Intelligence Science and Technology,Graduate School of Informatics, Kyoto Universitytsuchiya@pine.kuee.kyoto-u.ac.jp, ... unreadable.The goal of our study is to present tools that helprewriting work of improving readability in Japanese.The first tool is to help detect the sentence frag-ments (words and phrases) that should ... patterns that are defined in this first way. In the second way,a grammar element is described as a pair of its pat-terns and its examples. The following pair is an ex-ample of the grammar element that...

... Effect of echinomycin on HIF-1a protein level. HepG2 and HeLa cells were incubated for 5 or 16 h under hypoxia or normoxia in thepresence or absence of increasing concentrations of echinomycin. ... effect is caused by an increase in HIF-1a pro-tein level, resulting from an increase in the transcription of the HIF-1Agene in the presence of a low concentration of echinomycin. Transfectionexperiments ... Hypoxiamarkedly increased HIF-1 DNA binding activity. Theincubation of cells with echinomycin during normoxiaor hypoxia had a minimal effect on the HIF-1 DNAbinding activity detected in the nuclear...

... samples of wordsserve as input to the training procedure. In a treebank training step we observe for eachrule in the training grammar how often it is usedfor the training corpus. The grammar rules ... want to examine the in- fluence of the size of the training corpus on theresults of the evaluation. Therefore, we split the training corpus into 9 corpora, where the size of the corpora increases ... combining the advan-tages of treebank and bracketed corpora training. We investigate the effect of the training corpus size on the perfor-mance of our system. The evaluationshows that a hand-written...
