Abstract:
While strings and syntax trees are used by the Natural Language Processing community to represent the structure of spoken languages, these encodings are difficult to adapt to a signed language like American Sign Language (ASL). In particular, the multichannel nature of an ASL performance makes it difficult to encode in a linear single-channel string. This paper will introduce the Partition/Constitute (P/C) Formalism, a new method of computationally representing a linguistic signal containing multiple channels. The formalism allows coordination and non-coordination relationships to be encoded between different portions of a signal. The P/C formalism will be compared to representations used in related research in gesture animation. The way in which P/C is used by this project to build an English-to-ASL machine translation system will also be discussed.
