 +  * test alignment with synonym detection (cz_wn required) = separating ''lex::'' and ''disam::''
 +  * try misplaced phrase detection
 +    * parse the reference, extrapolate unto the hypothesis via word alignment, get phrases from there
 +    * group adjacent words aligned to the same word? (imitation)
 +  * order evaluation
 +    * currently finds misplaced items, but their shift distances are off
 +    * not important for ''ows'' vs ''owl'', but
 +      * to fix -- for every misplaced token
 +        * if it (and only it) were to be moved in the original permutation, what would be the best place?
 +        * evaluate with nr. of intersections
 +  * try domain adaptation for word alignment with the "via source" alignment (EMNLP 2011 paper)
 +  * technical
 +    * comb and comment the code
 +    * add help files
 +    * integrate with the rest of Addicter
 +  * approach applicable to learner's corpora
