Software Design for a Fuzzy Cognitive Map Modeling Tool 1997. |

PDF |
|
Fuzzy cognitive maps are qualitative tools useful for rapidly examining relationships between domain concepts. They draw on soft computing concepts from the areas of fuzzy logic and neural networks. They are computationally inexpensive and permit convenient examination of various scenarios and options. We have presented an object oriented design arrived at using OMT for an FCM modeling application. Written in Java, it will permit desktop experimentation with FCMs and World Wide Web-based publishing and examination of FCMs built with the tool. This design anticipates a need for code reuse in the domain of digraph construction. The core classes of the application have been designed using a variation of the common model - view paradigm and segmented in such a way as to promote software reuse. Given the project's focus on the use of FCMs, we sought aids to productivity in areas that do not directly bear on this focus. We found user interface assistance in Laffra's animation of Dijkstra's shortest path algorithm, a layout code generator in Microsoft's Java development environment, and classes supporting streamed persistence. We examined the latter's shortcomings and proposed modifications to improve performance. These proposals will be addressed as time permits in the remainder of the project. A basic implementation of a machine learning algorithm from the literature will be incorporated in the finished application. We have reviewed the algorithm and specified a simple file format supporting its implementation. (AU) |

Programmers spend a significant amount of time in understanding existing programs for the purpose of program maintenance and further program development. Extracting internal program information can greatly help programmers to achieve this target. In this paper, a new mechanism is introduced in language-based editing systems to extract internal program information. The new model is evolved from the integration of attribute grammars and relations, drawing upon the advantages of both. The extraction of internal program information is used in two ways: 1) performing static-sematic analysis in language-based editing systems, 2) unveiling program dependencies for program comprehension. The model has been used in our generating system for the language-based editing system, TextSyn [1], and has been proven to be useful and powerful. (AU) |
