ClassfreqEntry

typedef mootLexfreqs::LexfreqEntry moot::mootClassfreqs::ClassfreqEntry

Type for frequency lookup table entries.

LexClass

typedef mootTagSet moot::mootClassfreqs::LexClass

Type for a lexical class ("ambiguity set")

ClassfreqTable

typedef hash_map<LexClass, ClassfreqEntry, LexClassHash, LexClassEqual> moot::mootClassfreqs::ClassfreqTable

Type for the lexical-class frequency lookup table.

TagfreqTable

typedef hash_map<mootTagString,CountT> moot::mootClassfreqs::TagfreqTable
