An Incompleteness Handling Methodology For Validation Of Bayesian Knowledge Bases, David J. Bawcom
An Incompleteness Handling Methodology For Validation Of Bayesian Knowledge Bases, David J. Bawcom
Theses and Dissertations
The PESKI (Probabilities, Expert Systems, Knowledge, and Inference) system attempts to address some of the problems in expert system design through the use of the Bayesian Knowledge Base (BKB) representation. Knowledge gathered from a domain expert is placed into this framework and inferencing is performed over it. However, by the nature of BKBs, not all knowledge is incorporated, i.e. the representation need not be a complete representation of all combinations and possibilities of the knowledge, as this would be impractical in many real-world systems. Therefore, inherent in such a system is the problem of incomplete knowledge, or spaces within the …
An Investigation Into The Use Of Software Product Metrics For Cobol Systems, Richard E. Boone
An Investigation Into The Use Of Software Product Metrics For Cobol Systems, Richard E. Boone
Theses and Dissertations
This thesis investigated several hypotheses that specific product measures could be used to predict later software lifecycle process or product measures. It collected software product and process measures from four consecutive major releases of a large Cobol legacy system (400K LOC). The types of product measures used were size and specific complexity measures. A statistical software package was used to calculate sample correlation coefficients between the measures. A 95% confidence interval was computed for each sample correlation coefficient that showed a strong or moderate linear correlation. The maintenance process measures provided were manhours used for each program changed or added, …
