A rapid prototyping/artificial intelligence approach to space station-era information management and access
Telematics and informatics
. ABSTRACT This effort has focused, and continues to focus, on applying rapid prototyping and Artificial Intelligence techniques to problems associated with Space Station-era information management systems. In particular, our work is centered on issues related to (1) intelligent man-machine interfaces applied to scientific data user support and (2) the requirement that intelligent information management systems (IIMS) be able to efficiently process metadata updates concerning types of data
... ed. The advanced IIMS represents functional capabilities driven almost entirely by the needs of potential users. The amount and complexity of scientific data projected to be generated by Space Station-era projects (e.g., Eos) is likely to be significantly greater than data currently processed and analyzed. Information about scientific data must be presented to potential users in a clear and concise way, with support features being incorporated to allow users at all levels of expertise efficient and cost-effective data access. Additionally, since data modifications and additions will frequently occur, mechanisms for allowing more efficient IIMS metadata update processes must be addressed. To this end, our work has examined the following aspects of IIMS design: (1) IIMS data and metadata modeling, including the automatic updating of IIMS-contained metadata, (2) IIMS user-system interface considerations, including significant problems associated with remote access, user profiles, and on-line tutorial capabilities, and (3) development of an IIMS query and browse facility, including the capability to deal with spatial information. A working prototype has been developed and is being enhanced. Future work will attempt to clarify a number of issues which have emerged from our present efforts, particularly concerning IIMS information base structure and its relationship to usersupport and distributed, heterogeneous database access. . INTRODUCTION This paper represents the culmination of our early examination of the areas of advanced information management and access using rapid prototyping and 'Artificial Intelligence (AI) programming techniques. In one sense, it is inaccurate to have only one section with the heading 'Results'. The entire paper reflects our current thinking concerning issues surrounding future IIMS operations and development, and all of what is written here is a direct result of our early prototyping efforts. To date, our work has served as a validation of the approach we have used since the initial prototype has helped to crystalize our thinking and drive out more specific system requirements. As a result of what we have accomplished, we are now in a position to move forward. Section 3 details our interpretation of global requirements advanced information systems will necessitate, and our understanding of current system limitations that compel the use of advanced concepts in both system design and implementation. Section 4 discusses our approach to implementing a prototype IIMS using the application domain of large science databases. Section 5 presents the current state of our prototype and concluding remarks concerning implications of our work. . BACKGROUND AND PROBLEM 3 .
