SOPHIA: A Practical Database Architecture
for Knowledge Storage and Retrieval
Abstract:
We have created a knowledge storage and retrieval system using a common relational database. The resulting system is simple but powerful, and can support many of the common tasks of other frame-based knowledge systems, while operating from commonly used database software. The system has been used to:- provide SQL access to a Knowledge Base (KB) of scientific data
- create a web-based KB browser and knowledge-entry tool
- act as a knowledge server for scientific applications
- provide user-level ownership and security of data
- cache information retrieved from external databases
