Evolution of empirical hardness with p (m=24, n=18, q=193). Notice the different time scales. while for the incomplete solvers in some cases it may appear as hard-hardereasy. 80 m 2 , RSat, minisat and picosat found the instances with p = 0 to be the hardest.

For instance, (tout)? [faire] (tout)? (ce)? was built, whereas two different patterns would have been better: tout [faire] and [faire] tout (ce)?. In another example, the pattern (qui)? (s’)? (en|` a)? [venir] made from the variants ` a venir, qui vient, qui viennent or qui s’en viennent is difficult to understand. We are counting on the input of end-users to help us decide on the optimum manner of displaying variant translations. 5 Discussion In this study, we have investigated the use of statistical word-alignment within TransSearch, a bilingual concordancer.

Although this clustering method is greedy and may not build the optimal tree, it has been extensively tested and usually finds a tree that is quite close to the optimal one. The neighbor-joining algorithm requires computing a distance matrix between each pair of transpots to align. A word-level specific edit-distance was empirically developed to meet the constraints of our application. Different substitution, deletion or insertion costs are introduced according to the grammatical classes or possible inflections of the words; it is therefore language dependent.
