VIM : 3 D Co - operative Diagrams as KBS
نویسندگان
چکیده
VIM demonstrates a 3D interactive diagram serving as a radically cooperative user interface to an Underlying Knowledge Base System (UKBS). VIM comprises a Prolog client linked by the In-ternet to a diagram graphics server linked by X/Motif to conventional 2D display hardware. The diagram integrates three concurrent layers of mixed-initiative, direct-manipulation interaction: (i) User-UKBS dialogue controlling beliefs presented in the diagram; (ii) Shared user-UKBS`browsing', controlling selectively emphasised selective viewing of a potentially much larger belief structure; (iii) Novel cooperative force-directed management of diagram layout. VIM's 3D diagrams have a constraining 3D spatial arrangement scheme and a xed principal view. Subjectively this arrangement aids expressiveness, comprehensibility and perceptual toleration of both link crossings and topological change in the 2D display, and inhibits browsing disorientation. We argue that this style of interface ooers fundamental beneets to knowledge engineers and end users.

3d Aids Cooperation with Diagrams That Think
A set of fundamental types of high-level interaction with diagrams is proposed. VIM, a prototype KBS with a 3D cooperative diagram as its user interface illustrates diierent layers of cooperation reeecting this classii-cation. Also a number of ways in which 3D aids such cooperation are identiied.
متن کاملKBS Methodology as a framework for Co-operative Working
This paper describes the development of the Injection Moulding Process Expert System (IMPRESS). The IMPRESS system diagnoses faults in injection moulding machinery which lead to dirt or other contamination appearing in the plastic mouldings which are produced. This KBS has recently been put into use at Plastic Engineers (Scotland) Ltd, and is proving useful both as an expert assistant when tech...
متن کاملUnifying SysML and OWL
To use OWL2 for modeling a system design one must be able to construct a Knowledge Base (KB) that can represent detailed information such as the number of occurrences of a part and interconnections between parts. SysML Block Diagrams (BD) have sufficient expressiveness to represent detailed designs. Suitably restricted SysML block diagrams can be translated into OWL2 to achieve the same result....
متن کاملCombined disc methods for the detection of KPC- and/or VIM-positive Klebsiella pneumoniae: improving reliability for the double carbapenemase producers.
Klebsiella pneumoniae strains co-producing klebsiella pneumoniae carbapenemase (KPC) and verona integron-encoded metallo-beta-lactamase (VIM) are frequently isolated in Greece and have also occurred in other European countries. Conventional combined disc tests exhibit low sensitivity against these emerging pathogens. We have evaluated modifications of the KPC/Metallo-β-Lactamase Confirmation ki...
متن کاملHow Does Primary Dairy Cooperative Perform? A Study of Physical and Financial Performance Variables in West Bengal State in India
This paper attempts to examine the physical and financial performance of some primary dairy co-operatives in west Bengal state in Indian context. The study suggests that financial performance indicators dominate over physical ones, and all the dominating variables have long term positive impact on primary milk producers’ co-operative societies (PMPCSs). Also, the significant impact of financial...
