Recognition: Advanced Topics
Using Advanced Topics in Recognition
In addition to setting the view's
flag, you need to create
slot in either the view or its
frame. The
slot stores a single dictionary identifier or an array of dictionary
identifiers. You need to install the custom dictionary in this slot using code similar
to the following example.
// vCustomDictionaries flag already set
dictionaries := mySpecialDictionary;
To use system-supplied dictionaries in addition to your custom dictionary, you can
enable additional view flags in the Entry Flags editor in NTK or set these
additional flags procedurally. If you prefer to set view flags procedurally, you must
use the
function to bitwise OR the
flag with any
bits already set in the
slot. In either case, your custom dictionary must
still be specified in the
Note that some view flags enable combinations of system dictionaries. If you want
to specify explicitly which system dictionaries the view can use, set no dictionary-
enabling flags other than the
flag and use system-
supplied dictionary ID constants to add specific dictionaries to the
slot. For descriptions of the system-supplied dictionary ID constants, see
"System-Supplied Dictionaries" (page 8-16) in Newton Programmer's Reference.
The following code fragment shows how you can specify dictionaries explicitly
by including the appropriate constants as elements of the array in the
dictionaries :=[mySpecialDictionary, kUserDictionary,
Regardless of the order of elements in the
array, the system
always searches the user dictionary first. The system then searches all of the
specified dictionaries in the order that they appear in the
array. In
general, the order in which this array's items appear is not critical, except in the
case of conflicting capitalization information for representations of the same word
in multiple dictionaries. When multiple dictionary entries match the input, the
system uses the first dictionary entry that was matched.
Note that the printed recognizer can always return words not present in
dictionaries. Only the cursive recognizer may be restricted to returning only words
present in dictionaries (and then only when letter-by-letter recognition is not
enabled). To test your dictionary settings, use the cursive recognizer while its
letter-by-letter option is disabled.
