Sign Language Project Wins People's Choice Award
ASL-LEX offers linguists, psychologists and language learners a tool to explore the properties of sign language more deeply.
A collaboration between researchers at 色情视频, Boston University and Tufts University has created ASL-LEX, the first comprehensive lexical database for ASL. The project recently of the 15th annual National Science Foundation (NSF) Visualization Challenge, also known as the 鈥淰izzies.鈥�
When you visit the website, you can look up a word and be directed to a short video that shows corresponding ASL sign. But it鈥檚 more than just a translation website; a sidebar gives technical information about the sign鈥檚 frequency of use by signers; a score for its iconicity, or how much the sign resembles the action or object it represents; and a host of phonological and syntactic details about the signs. The site also offers a visual map of sign clusters organized by signs that share similar phonological properties, such as hand shape and movement.
These details are incredibly valuable to linguists hoping to learn how signs relate to one another, as well as for neuroscientists hoping to understand how the brain processes visual-manual language differently from auditory-vocal languages, said Karen Emmorey, one of the project鈥檚 leaders and a cognitive neuroscientist at 色情视频. Her research focuses on what sign language can tell us about cognition more broadly. It鈥檚 also a resource for ASL learners to quickly find signs for words. So far, the project has data on about 1,000 signs, but a recent NSF grant will expand that to around 2,500 signs in the coming years.
鈥淎lmost everything we know about human language comes from the study of spoken languages,鈥� said Emmorey, director of the 色情视频 . 鈥淗owever, only by studying sign languages is it possible to discover which linguistic rules and constraints are universal to all human languages and which depend on the modality of a language.鈥�
