Title: Non-Syntactic Word Prediction for AAC

Abstract:

Most icon-based augmentative and alternative communication (AAC) devices require users to formulate messages in syntactic order.
Reliance on syntactic ordering, however, may not be appropriate for individuals with limited or emerging linguistic skills. Some of these users may benefit from unordered message formulation accompanied by automatic message expansion to generate syntactically correct messages. Leveraging word prediction to increase communication speed in unordered message formulation, however, requires new methods of prediction. This paper describes a novel approach to word prediction using semantic grams or "sem-grams," which provide relational information about message components, regardless of word order.
Performance of four word-level prediction algorithms, two based on sem-grams and two based on n-grams, are compared on a conversational corpus. Results showed that sem-grams yield accurate word prediction, but lack prediction coverage. Hybrid methods that combine n-gram and sem-gram approaches may be viable for unordered prediction on icon-based AAC devices.
