Symbolics Inc, Cambridge, Massachusetts, yesterday announced Joshua, and claimed it to be a breakthrough programming language and software development environment for building expert systems. It also added an object-oriented database system called Statice. It looks to Joshua to close the loop between development and delivery of large artificial intelligence systems. The firm says Joshua is a programming language with full Lisp capabilities embedded in an artificial intelligence development environment going far beyond what anyone else has done, and looks to 60% of current customers to want to use it. It will be offered on all Symbolics workstations and on Ivory boards, from June, at $15,000 per CPU.
