Uniqueness point DC (lemma) prefix length


Length of the shortest prefix uniquely identifying the single lemma associated with the downcased type. For downcased types with two or more lemma associations, no such prefix exists, and a value of 0 is given. For all other downcased types (those mapping to a single lemma), all possible continuations of the downcased type must point to the same single lemma, otherwise the value will still be 0. If both conditions are fulfilled, a shortest prefix can be determined which uniquely identifies the single lemma of the downcased type and all its continuations. The value given then is the length of this prefix.

For an example, please see the documentation for the case-sensitive version of this measure, Uniqueness point (lemma) prefix length.
