Motivated by the problem of automatically com- posing network accessible services, such as those on the World Wide Web, this paper proposes an approach to building agent technology based on the notion of generic procedures and cus- tomizing user constraint. We argue that an aug- mented version of the logic programming lan- guage Golog provides a natural formalism for au- tomatically composing services on the Semantic Web. To this end, we adapt and extend the Golog language to enable programs that are generic, customizable and usable in the context of the Web. Further, we propose logical criteria for these generic procedures that define when they are knowledge self-sufficient and physically self- sufficient. To support information gathering com- bined with search, we propose a middle-ground Golog interpreter that operates under an assump- tion of reasonable persistence of certain informa- tion. These contributions are realized in our aug- mentation of a ConGolog interpreter that com- bines online execution of information-providing Web services with offline simulation of world- altering Web services, to determine a sequence of Web Services for subsequent execution. Our implemented system is currently interacting with services on the Web.
