  abstract= "Although the use of Fourth Generation Languages has greatly
     increased the efficiency of the system development process,
     the validation of system specifications is still considered
     to be complicated and time-consuming. A \"Parallel
     Semantic Net Engine (PSNE)\" has been developed as part
     of a research project carried out in the Department of
     Computer Science at Exeter University to investigate into
     this area. This project was initiated by a software house,
     Softwright Systems Ltd., which has made extensive use of
     Fourth Generation Languages.The purpose of this project was
     to construct an engine which would be fast enough to
     validate a system specification in realtime, giving
     immediate feedback to the user when constraints are
     violated. The areas of knowledge representation and parallel
     processing were explored. A Parallel Semantic Net Engine was
     proposed in order to take advantage of the richness of
     semantic networks in representing complicated relationships
     and the power of transputers in speeding up the processing.
     Figure 1 shows the general model of the PSNE.The model is
     distributed over of a host PC and a network of transputers.
     On the PC side, there are the application generator,
     generated applications and a standard relational database
     which stores the application data. A front-end would be
     developed running on the PC to act as the gateway for data
     passing between the PC and the transputers."
