Section I of this report gives some background information on the LADDER system, outlines the changes made to the architecture of the system, and briefly explains the enhanced capabilities produced by those changes. Section II discusses user experiences with the first-generation LADDER system and the response of SRI to the reports of those experiences. Section III describes new user features that have been added to LADDER. Section IV discusses SODA, an improved data access system for LADDER, explaining its new capabilities and the problems of supporting those capabilities in accessing distributed data. Section V describes how the system has been extended to access a heterogeneous data base consisting of both Datacomputer and DBMS-20 data base management systems. Section VI reports on progress to date in bringing the results of our longer- term research into the LADDER system, in the form of a new natural-language processor that will permit a greater range of natural-language questions and lay the groundwork for transporting the system to new data bases and new domains. Section VII lists the publications and presentations by the project staff during the period covered by this report. Finally, Appendix A gives more detail on the new formal query language for data access, and Appendix B describes an experimental French-language version of LADDER.
