Natural Language Dialogue Service for Appointment Scheduling Agents
Appointment scheduling is a problem faced daily by many individuals and
organizations. Cooperating agent systems have been developed to partially
automate this task. In order to extend the circle of participants as far as
possible we advocate the use of natural language transmitted by e-mail. We
describe COSMA, a fully implemented German language server for existing
appointment scheduling agent systems. COSMA can cope with multiple dialogues in
parallel, and accounts for differences in dialogue behaviour between human and
machine agents. NL coverage of the sublanguage is achieved through both
corpus-based grammar development and the use of message extraction techniques.Comment: 8 or 9 pages, LaTeX; uses aclap.sty, epsf.te
An optimization framework for solving capacitated multi-level lot-sizing problems with backlogging
This paper proposes two new mixed integer programming models for capacitated multi-level lot-sizing problems with backlogging, whose linear programming relaxations provide good lower bounds on the optimal solution value. We show that both of these strong formulations yield the same lower bounds. In addition to these theoretical results, we propose a new, effective optimization framework that achieves high quality solutions in reasonable computational time. Computational results show that the proposed optimization framework is superior to other well-known approaches on several important performance dimensions
The computer integrated documentation project: A merge of hypermedia and AI techniques
To generate intelligent indexing that allows context-sensitive information retrieval, a system must be able to acquire knowledge directly through interaction with users. In this paper, we present the architecture for CID (Computer Integrated Documentation). CID is a system that enables integration of various technical documents in a hypertext framework and includes an intelligent browsing system that incorporates indexing in context. CID's knowledge-based indexing mechanism allows case based knowledge acquisition by experimentation. It utilizes on-line user information requirements and suggestions either to reinforce current indexing in case of success or to generate new knowledge in case of failure. This allows CID's intelligent interface system to provide helpful responses, based on previous experience (user feedback). We describe CID's current capabilities and provide an overview of our plans for extending the system
