4.10.5. Prediction Dialog: Auto Learning
By default, your Palmtop device does not learn new words as you type them. You can change this setting by
using the
Auto Learning drop-down menu. If you select With Prompt , every time you type a word that is not
in the dictionary, a dialog will pop up and ask if you want to add the word to the dictionary. If you select
Always , new words will automatically be added to the dictionary. The Never option means that Palmtop will
ignore unknown words. Remember that you can always add new words by hand using the Dictionary Editor.
Be careful when enabling the
Auto Learning option - the program cannot tell a misspelling or a typo from a
new word, so it will add these mistakes to the dictionary as if they were words. If you do have mistakes in
the dictionary, select the
View Personal button from the Dictionary Editor dialog to browse through the auto-
learned words (see section 4.12.5).
4.10.6. Prediction Dialog: Prediction Database
The dictionary used for word prediction can be adjusted using the Database drop-down menu. Three
dictionary options are available by default: Small (2,000 Words), Medium (10,000 Words), and Large (30,000
Words). A smaller dictionary may be suitable for users with smaller vocabularies, or for users who find that
the additional predictions made by the larger databases are distracting. When the dictionary is changed, your
Palmtop device must completely reload the current configuration. Please note that loading the
Large
database may take several minutes.
4.10.7. Prediction Dialog: Prevent Redundancy
Suppose that you are trying to type the word "therefore." This is a relatively uncommon word, so it probably
will not appear in the prediction list until you have already typed its first few letters. However, "there" is a very
common word that shares the same first five letters. You will probably see "there" in the prediction list after
you have typed "t," and "th," and so on. It is taking up space in the prediction list that could be used to offer
different words, perhaps the word that you want to type. If you select the
Prevent Redundancy check box,
the software will automatically eliminate words from the prediction list if they appear more than twice in
succession. With redundancy prevention enabled, "there" might appear after "t" and "th", but once you typed
"the," the software would remove it from the list to make room for a different word.
4.10.8. Prediction Dialog: Static Predictions
By default, your Palmtop device will use all of the information available to make its predictions as accurate
as possible. This includes information about words that appeared earlier in the current sentence. This means
that the contents of the word list will vary depending upon the last few words you typed. For example, if you
typed, "The dog is t" the first word in the list might be "trying,” but if you typed "Climb the t," the first word in
the list might be "tree.” For some users, a word prediction list is more useful if it does not change quite so
much. By selecting the
Static Predictions check box, you can set your Palmtop device to ignore the past
few words when making its predictions. For example, when you type "t" you will always see "the" first in the
list.
4.10.9. Prediction Dialog: Recency
In oral or written communication, people tend to reuse words that have occurred recently. If you select the
Recency check box, your Palmtop device will make words that occurred most recently appear earlier (with
fewer initial characters typed) in the prediction list. The last 100 words are used for recency computations.
