Abstract:
We introduce our recent awarded research proposal that aims to bring speech and language research in neuroscience and computer science. Current artificial intelligence (AI), especially in nature language processing (NLP) is heavily relying on extracting statistical regularity of texts or sounds to mimic human linguistic behavior, but largely independent from the true cognitive processes in our brain. To achieve the “Strong AI" that closely resembles our human intelligence, computer science models need to approximate cognitive processes. We approach this problem from two aspects (representation and computation) in five levels of analysis in linguistic research (lexical/semantics, syntax, syntax semantics interaction, speech, and neural disorder and network). We hope this endeavor provides benefits in both disciplines – 1) to update AI models by integrating cognitive neuroscience mechanisms and 2) to advance understanding of neural mechanisms by the inspiration from computer science. We present a study at the semantic level as an example. Different computer science models can generate distinct semantic spaces from text corpus to represent the meaning of words. However, which model is closer to the true semantic representation in our brain? We evaluate computer semantic models by a neural measure of semantic distance – N400. Preliminary results of correlation between the semantic distance generated by computer science models and neural measures have a clear dynamics and spatial distribution, suggesting the possible connection of semantic representation across disciplines.
