Abstract In this chapter, we provide a geometric construction of manifold extending given Galois cover to wreath product, using composita and fiber products. For be possible, certain assumption on the homology, previously called (∗), needs strengthened new condition (∗∗) (equivalent in most cases). To motivate use condition, first recall connection between homology quotient coinvariants. Apart ...

Adapting the vocabulary of a speech recognizer to the utterance to be recognized has proven to be successful both in reducing high out-of-vocabulary as well as word error rates. This applies especially to languages that have a rapid vocabulary growth due to a large number of inflections and composita. This paper presents various adaptation methods within the Hypothesis Driven Lexical Adaptation...
