> Could you state briefly what do you understand by "NLP with a cognitive > view"? With the (unsuccessful) term "cognitive view to NLP", I refer mostly to connectionist modelling and also other approaches that incorporate evidence from cognitive science about language organization in the brain for producing models for language processing. >What cognitive aspects of language processes would say that depend on > the particular form that has been chosen for writing a language on paper (or > a computer screen)?> On the one hand, SignWriting is a writing system, i.e. a set of symbols for encoding signs . Therefore, for any evaluation or comparison to other writing systems or transcription systems, what would matter are the units for which symbols have been selected and not the symbols themselves. Moreover,when considering using SW input for NLP the basic issue would be the computer readability of the .sgn format (if the computer can read the phonological elements of the sign). Thus, a cognitively plausible model for sign language processing could not be based on the form of the input. On the other hand, SignWriting is easy to learn and use mostly because it is iconographic. This fact implies a possible correspondence of SW to cognitive aspects of sign language processing in the brain, such as the visual-perception, understanding, production and acquisition mechanisms. Could a computational model exploit SignWriter's iconicity to get closer to cognition-based aspects of sign language realization? How? For example could the extraction of the phonological features from the .sgn format be based on a model for sign visual perception process? | ||||||||
