The intuition behind the objective evaluation experiment is that the capacity of our tool to find indirect translation equivalents in comparable corpora can be compared with the results of automatic alignment of parallel texts used in translation models in SMT: one of the major advantages of the SMT paradigm is its ability to reuse indirect equivalents found in parallel corpora (equivalents that may never come up in hand-crafted dictionaries).
automatically generated GIZA++ dictionaries with word alignment contain many examples of indirect translation equivalents.
