Next: Example: nlp_speech method.
As a trivial example of such a method, consider the problem of finding
the best path through the word-graph ignoring all aspects but the
acoustic scores present in the word-graph. In order to implement a
to solve this problem, we define weights
using a unary tuple
. The initial weight is
is defined as
Note that we specify an infinite weight for category edges because we
want to ignore such edges for this simple method (i.e. we are simply
ignoring the results of the parser). We define an ordering
on such tuples, simply by stating that
iff w < w'.
