[CWB] Giza ++ and CQPWeb

[Annarita Felici]

Hi Stefan, 

thanks for the info about the CWB alignment. 
I am not sure whether an automatic word alignment will be good enough for corpus searches. I just assume so. Ideally, I'd like the possibility to search for translation equivalents with their usage context and also be able to do linguistic searches as in CQPWeb. I have tried several aligners at sentence level (Vanilla, LF Aligner, You align), but the output German-Italian is not great. I ran a test on Paraconc which allows translation searches and has sentence alignment, but candidate translations are not correctly spotted. The main problem are trennbare Verben, Partizipialsätze, eingebettete Satzglieder. On the other hand, my texts have identical sentence breaks and except for single segments within the sentences, a 1- to-1 simple is not too bad.  I might give a go to Uplug as also Ruprecht mentioned in his message.
Best,

Annarita

CWB alignment attributes are designed for sentence-level alignment, not for word alignment.  Depending on how complex your word alignment is, the CWB mechanism could in theory be abused to store the alignment information, but its use in CWB would be severely limited and CQPweb would not be able to display it properly.

Are you sure that the automatic word alignment will be good enough for use in corpus searches?  If you're satisfied with a simple 1-to-1 alignment, you could possibly encode just the aligned words in a p-attribute and display it as a "gloss" in CQPweb.

Best,
Stefan
