It may appear, therefore, that there are three chunks in the English string and only two on the French side, but this is not the case: The restriction that each segment must contain at least one non-marker word ensures that we have just two marker chunks for the English string in (18).
it remains the case that the chunks are tagged differently; we obtain the marker chunks in (19): (19) English: <DET> The man looks <PREP> at <DET> the woman French: <DET> L' homme regarde <DET> la femme Our alignment method would therefore align the first English chunk with the first French chunk, as their marker categories match.
