15. Design of CAPP

16. Design of CAPP (contd.) Receives interpreted context and decides as which is the best available service that should be delivered to the client or returns a list of probable services to the client Description Makes decision on which service is to be delivered to the client on the basis of interpreted context and weighted averages of the interpreted contexts Function Decision Making Module This module interprets the gathered context by and identifying Who, What, Where & When contexts Description To interpret the gathered context as Who, What, When & Where contexts of both the user and the services Function Context Interpreter This module gathers context data. Description Gather context data on the basis of client’s info and request and represent the gathered information in the form enforced by the rule Repository Function Context Congregator This module listens to incoming requests and forwards them to the congregator for context gathering. Description Receives request and dispatches it to the context congregator module. Returns the result to the requester Function Dispatcher Module
