Moreover, we want to encourage similar documents to align to each other. ... similarity are used to identify target language documents that are close to the translated document. The second approach is to use training data of aligned document pairs...

The tree construction level is similar to the DOP approach (Bod, ... 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 fu...

The value assignment is for convenience of computing averages, since it is more appropriate to treat these measures ... With the individual key concepts available, we proceed to cluster these concepts in order to identify major subtopics within the main topic. Clusters are formed through...
