Furthermore, the number of codebook ... the other way around. Composition of feature vectors: Another lesson of Tab. 3 is that the effect of the com- position of the feature vectors can vary depend...

The results indicates that there are statistically no differences at .05 level to the number of characters ... two-party dialogues? For example, are there any possibilities if in multi-party di- alogues the role of chairpersons emerges from the nature of the dialogues? T...

For space limitations most of the proofs are omitted; they can be found in the complete paper [2] the form xLy, where L is a finite description of a regular language of ... the consistency check. Additionally, one has to consider the effects of in- troducing the path terms/~.a~. The main part of this task is to resolve constraints of...

Regarding the interpretation of the results, if the ratio ... we look at the number of undecided cases is that the problem of data sparseness is much more severe if we consider the concordances of the homographs rather tha...

The finding that the effect of CoASH depends on the presence of ATP (although not of other NTPs such as GTP and UTP; not shown) suggests that it is indirectly mediated via the formation of ... 20%, despite the presence of ATP- Mg. It is shown below that this is due to loss of the inhibitory effect of ATP-Mg, consequent to the removal of a heat-stable co...
