Center node: "Some Issues in Analysis and Specialization of Modular Ciao-Prolog Programs"
  Abstract: Abstract   Separating programs into modules is a well-known technique which has proven very useful in program development and maintenance. Starting by introducing a number of possible scenarios, in this paper we study different issues which appear when developing analysis and specialization techniques for modular logic programming. We discuss a number of design alternatives and their consequences for the different scenarios considered and describe where applicable the decisions made in the Ciao system analyzer and specializer. In our discussion we use the module system of Ciao Prolog. This is both for concreteness and because Ciao Prolog is a second-generation Prolog system which has been designed with global analysis and specialization in mind, and which has a  strict  module system. The aim of this work is not to provide a theoretical basis on modular analysis and specialization, but rather to discuss some interesting practical issues.  The authors would like to thank Francisco Bueno for many interesting discussions on analysis of modular programs, and the anonymous referees for their constructive comments. This work was funded in part by Spanish CICYT projects TIC99-1151 EDIPIA and TIC97-1640-CE.
