Academic literature on the topic 'Use case diagram'

The use case diagram is one of the diagrams commonly taught in colleges of computer science. Assessment of use case diagrams is often an obstacle for a teacher in the learning process. It is due to the interpersonal and intrapersonal problems of the teacher in assessing. Interpersonal problems are caused by the absence of an assessment standard among teachers. Intrapersonal problems are caused by the inconsistency of a teacher in assessing many diagrams of student answers. This research aims to create a semantic use case diagram automatic assessment method. Semantic assessment is divided into two kinds, namely property and relationship. All information used is a label translated from the XMI document. Similarity assessment between labels used cosine similarity, employing WuPalmer to perform WordNet searches. The results showed that the proposed method had a substantial agreement with the teacher as an expert; however, a teacher tends to look at property information rather than relationship information to assess use case diagrams.

Abstract Nowadays, the topicality and applicability of model-driven development in the object-oriented development approach has increased, so it is important that created models and diagrams display not only the content, but also visually reflect information. Transparent diagram placement that influences work productivity is important for displaying information. Manual layout of diagrams is a time-consuming activity, which can also be ineffective, so in this paper the application of UML use case automatic layout is reviewed. The paper also examines the requirements of use case diagrams and placement criteria, which will serve as a basis for the creation of an automatic use case diagram layout algorithm.

Reusing software has several benefits ranging from reducing cost and risk, accelerating development, and its primary purposes are improving software quality. In the early stage of software development, reusing existing software artifacts may increase the benefit of reusing software because it uses mature artifacts from previous artifacts. One of software artifacts is diagram, and in order to assist the reusing diagram is to find the level of similarity of diagrams. This paper proposes a method for measuring the similarity of the use case diagram using structural and semantic aspects. For structural similarity measurement, Graph Edit Distance is used by transforming each factor and use case into a graph, while for semantic similarity measurement, WordNet, WuPalmer,and Levenshtein were used. The experimentation was conducted on ten datasets from variousprojects. The results of the method were compared with the results of assessments from experts.The measurement of agreement between experts and method was done by using Gwet’s AC1 andPearson correlation coefficient. Measurement results with Gwet’s AC1 diagram similarity are 0,60,which were categorized as “moderate" agreement and the result of measurement with Pearsonis 0.506 which means there is a significant correlation between experts and methods. The resultshowed that the proposed method can be used to find the similarity of the diagram, so finding andreuse of the diagram as a software component can be optimized.

The Unified Modeling Language - UML - is the most used specification language, and the way the world models not only application structure, behavior, and architecture, but also business process and data structure. In this paper, we aim to demonstrate a system development methodology by generating the UML diagrams from the requirements of the Automatic Banking Machine (ABM) System and discuss their relationships, differences and suitability. The high-level requirements of the system are specified by using use-case diagram, activity diagram, state chart diagram, collaboration diagram, sequence diagram, and component diagram, and the low-level requirements of each component using class diagrams. We briefly introduce each diagram, their usage, their advantages and some limitations, and then we discuss the relationships and differences between two or more diagrams, and suitability for modeling the different parts of the system.

PurposeDisclosure research has argued that visuals are increasingly used in annual reports as a way to increase readability of the annual report, but comparatively little is known about of diagrams compared to graphs and photographs. The purpose of this paper is to provide a historical account of visuals use in corporate disclosure, with an emphasis on diagrams, to show changes from the 1940s until present-day reporting.Design/methodology/approachVisual research methods were applied to analyze how diagrams, photographs and graphs were used in 69 annual reports of the Swedish telecom company Ericsson.FindingsPhotographs have been used with increasing frequency since the 1950s. Graph and diagram use has increased significantly since the 1990s while photograph use remained stable, suggesting that graphs and diagrams increasingly complement photographs for visually representing the organization in corporate disclosure. Factors explaining the case company’s development include both internal (performance, individual preferences, shifting from a manufacturing-based strategy to a service-based strategy) and external (legislation, transformation of the telecom industry).Originality/valueVisual elements in annual reports are increasingly oriented toward immaterial representations of the organization’s standings and identity and diagrams are increasingly used and contribute to this. This finding motivates further research about diagram use in corporate communication, such as how different diagram types convey accounting messages, and whether diagrams serve as impression management devices. For regulators, it will be important to follow the emerging trend of diagram use, since it is becoming part of reporting practice.

In this work, based on the results obtained concerning the analysis and the needs of our project which concerns the design and development of an e-Learning project management system, we present the modeling stage with UML. Based on one hand, on two diagrams: class diagram and use case diagram, for static modeling and on the other hand, based on three diagrams: activity diagram, sequence diagram, diagram transition state for dynamic modeling. Finally, we offer examples of models for our project.

This paper is an effort to assess the groundwater quality and the geochemical processes mainly using the Chadha’s diagram which classifies natural waters and documents the Piper and extended Durov diagrams. Chadha’s diagram is a useful tool to interpret groundwater geochemical processes because it is produced by simple spreadsheets excel files. The example of hydrochemical analyses were given from groundwater samples of the Thriassion Plain. To attend our objective, 38 groundwater samples were collected. Hydrochemical sections, XY diagrams, distribution maps of ionic ratios as well as the Gibbs diagrams were used to identify origin of salinity and the hydrogeochemical processes that have taken place. The Gibbs diagrams have shown that evapotranspiration (ET) and rock-water interaction play an important role to the increase of groundwater salinity. The interpretation of Chadha diagram highlights that the stratigraphic factors and especially the clay strata occurrence have isolated fresh groundwater from seawater. The abundant occurrence of clay deposits to the depth of the plain work as barriers to direct seawater intrusion. Good quality groundwater identified confirms the important role of clay strata. Reverse cation exchange, is the predominant geochemical process in the Thriassion Plain aquifers, whereas evapotranspiration (ET) and rock-water interaction play an important role to the increase of groundwater salinity.

E-learning plays a significant role in educating large number of students. In the delivery of e-learning material, automatic e-assessment has been applied only to some extent in the case of free response answers in highly technical diagrams in domains like software engineering, electronics, etc., where there is a great scope of imagination and wide variations in answers. Therefore, the automatic assessment of diagrammatic answers is a challenging task. In this article, algorithms that compute the syntactic and semantic similarities of nodes to fulfill the objective of automatic assessment of use-case diagrams are described. To illustrate the performance of these algorithms, students' use-case diagrams are matched with model use-case diagram. Results from 13,749 labels of 445 student answers based on 14 different scenarios are analyzed to provide quantitative and qualitative feedback. No comparable study has been reported by any other label matching algorithms before in the research literature.
