A Hand-Held Multimedia Translation and Interpretation System with Application to Diet Management
TABLE X: n-gram counts for version 2 of our system and 1/40% of the WMT08 News Commentary data set.
['[BOLD] Data set', '[BOLD] 1-gram', '[BOLD] 2-grams', '[BOLD] 3-grams']
The difference in translation times between v2 and 1/4% of WMT08 can be partly explained by the difference in n-gram distributions in their respective corpora. This increases the number of hypothesis that must be considered when translating, thus increasing the execution time. Notice that the automatic consolidation method implemented in v3 is applied once to the entire corpora before the training process, and to each individual user search afterward. The former is the one that affects the translation time, but it takes orders of magnitude less time than the translation itself. Therefore, there is no significant different in translation times between v2 and v3.
