            Abstract : 
The evaluation method and result of language pipeline including CxBVR for awareness service platform are described. CxBVR is a formalization of a free text in a rule-based context representation. The CxBVR compiler can generate a set of rules for each XML-based context. The experimental results showed: 1) when contexts were divided, the processing speed was three or four times as fast as when not divided; 2) constraint checking on context-based inference execution enabled situation awareness services more manageable and reliable; 3) loading XML by SAX became two or three times as fast as than DOM. Thus, the (contextual) language pipeline usage for awareness service platform was proved to be fit to situations.
