The VisuWords website may offer a glimpse of dictionaries of the future. It extends the technology of The Visual Thesaurus by using different designs and color codes for different types of relations–and is a dictionary rather than a thesaurus with meanings added. Synonyms are automatically available since the relationships are semantic rather than alphabetical.
All that is missing is the integrated grammar with the different forms of the words, e.g. drive, drove, driven, driving, something less important for English than other languages which have 30-40 verb forms, some regular, some not.
Anyway, it is fun to play with and dream about. Maybe we’ll bring it to alphaDictionary since the source is open.
