General Diagram-Recognition Methodologies
نویسنده
چکیده
The field of diagram recognition faces many challenges, including the great diversity in diagrammatic notations, and the presence of noise and ambiguity during the recognition process. To help address these problems, research is needed into methods for acquiring, representing, and exploiting notational conventions. We review several frameworks for diagram recognition: blackboard systems, schema-based systems, syntactic methods, and graph rewriting. Next we discuss the need for a computationally-relevant characterization of diagrammatic notations, the need to exploit soft constraints during diagram recognition, and the possibility that diagram generators may provide a useful source of information about notational conventions.

Requirements Specification in The Prometheus Methodology via Activity Diagrams
In this work we extend a popular agent design methodology, Prometheus, and improve the understandability and maintainability of requirements by automatically generating UML activity diagrams from existing requirements models; namely scenarios and goal hierarchies. The approach is general to all the methodologies that support similar notions in specifying requirements.
متن کاملResearch Models in Information Systems
The use of research models in driving scholarly investigation is of great importance in any field, including information systems (IS). As such, a taxonomy of IS research models should be of substantial value to the discipline. Such a taxonomy is developed in this article based on the IS research literature. Eleven model types are examined in detail in order to investigate how they are used by r...
متن کاملGabor Parameter Selection for Local Feature Detection
Some recent works have addressed the object recognition problem by representing objects as the composition of independent image parts, where each part is modeled with “low-level” features. One of the problems to address is the choice of the low-level features to appropriately describe the individual image parts. Several feature types have been proposed, like edges, corners, ridges, Gaussian der...

Object recognition from machine vision is a complex task that has, to date, no formal method of solution. The use of brightness contours instead of edges and the corresponding contour profile diagram, or fingerprint, can provide mathematically non-intensive comparisons that can be efficiently performed in a database. More than that, this method provides a formalism which claims to be appropriat...
متن کاملData Flow Diagrams versus Use Cases - Student Reactions
Data Flow Diagrams and Use Cases are two popular methodologies in teaching as well as in practice. We recently used both methodologies in teaching four sections of our required Systems Analysis course. Questionnaire results indicate that students prefer Data Flow Diagrams.
