Information retrieval for pathology information systems.
In a medical information system there is a serious need for assessing patient information in various ways. There is also a need for summarizing information in simple statistical tabular form. In this part we present and evaluate different techniques for query formulation, such as: QBE (Query-by-Example), SQL (Structured Query Language), GCL (Graphical Query Language). We also present a query processor for use in a pathology information system. This software system incorporates: a) A semi graphical tree structure interface (SGTSI) for query formulation, and b) Summary tables handling.
