NetWeaver Developer is a knowledgebase development system. This article # gives a brief history of the system, # summarizes key features of the software, # is a bit of a primer, describing basic attributes of a NetWeaver knowledgebase, and # provides secondary references that independently document some of the NetWeaver applications developed since the late 1980s (see the #References section in this article, as well as applications documented for the EMDS system). First, though, a word about knowledgebases. While there are various ways of describing a knowledgebase, perhaps one of the more central concepts is that a knowledgebase provides a formal specification for interpreting information.〔Walters, J.R., and N.R. Nielsen. 1988. Crafting Knowledge-based Systems. New York: John Wiley and Sons. 342 p.〕 Formal in this context means that the specification is ontologically committed 〔Gruber, T.R. 1995. Toward principles for the design of ontologies used for knowledge sharing. International Journal of Human-Computer Studies 43:907-928.〕 to the semantics and syntax prescribed by a knowledgebase processor (aka, an engine). == A brief history == NetWeaver was created in late 1991 as a response to ease knowledge engineering tasks by giving a graphical user interface to the ICKEE (IConic Knowledge Engineering Environment) inference engine developed at Penn State University by Bruce J. Miller and Michael C. Saunders. The first iterations were simply a visual representation of dependency networks stored in a LISP-like syntax. NetWeaver quickly evolved into an interactive interface where the visual environment was also capable of editing the dependency networks and saving them in the ICKEE file format. Eventually NetWeaver became "live" in the sense that it could evaluate the dependency networks in real time. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NetWeaver Developer」の詳細全文を読む スポンサード リンク
