....the physical environment and dynamically changing knowledge and of a more complex pragmatic component, thereby stressing the need for a clear architecture. We are also working on the issue of integrating such expansions within the approach to multiple underlying systems (MUS) as established by [Bobrow et al. 1990, Resnik, 1989] In the MUS approach, a user may need to combine the capabilities of more than one system (i.e. several DBs on various domains, expert systems, information retrieval systems, interfaces to simulation packages, etc. in order to perform a general task. For dealing with MUS, not only ....

....compete at least not in the near future. In the near term NLIs can only be useful either in cooperation with GUIs in multi modal interfaces, or in ecological niches where GUIs are simply inapplicable. Several projects have combined NL and graphics or menu based techniques for user interfaces (Bobrow et al. 1990, Cohen 1991, Neumann et al. 1993) JANUS (Bobrow et al. 1990) foresaw the use of menus and graphics in an NLI for disambiguation purposes. SHOPTALK (Cohen 1991) proceeds from a standard menu based interface, but allows a user to fill menu slots not only with the standard menu items, but also ....

....and other computer applications. All the applications connected to Ask were accessible to the end user through natural language requests. The user stated his her requests in English, and Ask transparently generated suitable requests to the appropriate underlying systems. Janus [59] 81] 102] [17] had similar abilities to interface to multiple underlying systems (databases, expert systems, graphics devices, etc) All the underlying systems could participate in the evaluation of a natural language request, without the user ever becoming aware of the heterogeneity of the overall system. ....

....mail systems, screen painters, word processors, etc) Ask translates each natural language request into a suitable expression, which is then directed to the appropriate underlying system. This way, the user views an integrated computer system, with natural language understanding abilities. Janus [17] has the ability to interact with databases, expert systems, decision support systems, graphics systems, etc. and all the underlying systems may be involved in the answering of a user s question. For example (the example is based on [17] when asked Which submarines have the greatest ....

....workstation In a wider perspective, it would be possible to use the idea of QLF transfer to create what might be called a multi lingual workstation . There is already a growing interest in the idea of using natural language as a standard for accessing knowledge based applications: for example, (Bobrow et al. 1990) describe a system in which English is used as a standard query language to access a set of knowledge based tools totaling over 800 different functionalities. The user is not obliged to state which tool or tools he wishes to use, the system deciding this automatically. Broadening the coverage of ....

....Zebu grammar compilation process detects any inconsistencies or ambiguities in the grammar definition. Zebu goes beyond the capabilities of parser generators such as UNIX yacc in further optionally generating (automatically) the definition of a domain, a hierarchy of data structures (LISP 1 See Bobrow et al. 1990 for an example of this sort of system. 2 We are concentrating here on the more recent NLL implementation; an earlier implementation in Refine (Laubsch and Nerbonne 1991) is no longer the focus of our efforts, even though we continue to maintain it for its usefulness in rapid prototyping. Refine ....
