Word Prediction

Prediction dictionary and user vocabularies at different age and grade levels

WiViK incorporates WordQ™ technology for its word prediction. WordQ is a separate application that runs at the same time as WiViK and displays predicted words within WiViK on-screen keyboards. As you type, correctly spelled words are continuously displayed. When you see the word you want to use, you can choose it with your pointing device or switch. You can also display a word with its different word endings. Using knowledge about the last word that you wrote, WordQ software also suggests relevant next words in your sentence.

A user vocabulary reflects your personal writing style. This user vocabulary continually adapts as you write and improves its performance as you use it. This vocabulary ensures words are suggested that you regularly use and understand, thus reducing confusion. A number of initial user vocabularies are included based upon starting, intermediate, and advanced writing styles. You can further customize your user vocabulary by adding novel words and by importing text files.

You can also create and use groups of words called topics, such as your favorite sport, the family pet, or general math concepts. When you write about one of your topics, its words are more likely to be suggested.

When WordQ encounters unfamiliar and misspelled words, it saves them for you to review at a later time. You can then delete a misspelled word or add a novel word to your vocabulary.

Prediction options

There are four options associated with word prediction:

  • Predict new words that you use enables WordQ to automatically add correctly spelled words to your vocabulary. Novel and misspelled words are put aside for you to review.
  • Predict words from the WordQ Dictionary suggests words from the WordQ Dictionary when appropriate words cannot be found in your vocabulary.
  • Predict next words displays the words that are most likely to follow the word you have just selected.
  • Adapt predictions based on how you combine words enables WordQ to learn which words you use to follow one another. If you have trouble with grammar, you may want to leave this option unchecked.
  • Predict words based on creative spelling enables WordQ to consider creative spelling when making its predictions. Whenever there are no words in WordQ’s dictionary beginning with the letters that you type, WordQ will suggest words that take into consideration possible spelling/typing mistakes. Also, when you highlight a word, creative spelling will be considered when predicting words, i.e., spell checked.

In addition to suggesting correct spelling, any novel words and misspelled words are put aside for later review.

Customized topic-specific vocabularies

Customizing a vocabulary for specific needs is done at two levels. A user vocabulary may be customized for an overall writing style by importing samples of text files. Importing text is similar to the adaptation that occurs naturally over time, but it is done quickly. The user vocabulary may initially start as a blank or with just core function words. When text files are imported, they are automatically analysed for word usage and the word prediction will then take on the writing style of the source documents. There are no limits on the number of user vocabularies that may be created.

You can also easily add and use topic lists of words/phrases that emphasize those words in the prediction process. For example, a topic may be a list of baseball terms, a list of Prime Ministers, or a list of dinosaurs. Topic words are essentially user vocabulary words that are singled out for boosting in the prediction process. Because they are user vocabulary words, they will have word usage data and hence they will be shown only when appropriate. When creating a topic list, novel words are automatically added to the user vocabulary.

While only one topic active can be active at a time, there are no limits on the number of topics that you use. You can switch between topics at any time (e.g., between sentences or paragraphs). When a topic is active, words within that topic are more likely to appear.
