... chunk-parsing strategy to factor out recursion and to resolve only unam- biguous attachments. Since chunks are by definition non-recursive structures, a chunk of a given category cannot fully automatic recognition ... with a stored instance ex- ists. In all other cases, the most similar tree from the instance base needs to be modified to match the chunked input. This means that the outp...
