TL;DR: This system was developed with the extreme programming development method with system design using a unified modeling language, namely use case diagram, class diagram, and activity diagram, so that this system was fit for use functionally.
Abstract: Sukarame District serves public administration activities such as information on population data and mail administration services. The conventional process currently running in Sukarame District only uses Microsoft Office for data storage so that it cannot be accessed by people in real-time. As a solution to the problem, we need a system that can help public service management to manage population data, public complaints, and service letters such as environmental permits, electricity subsidy permits, and business permits. This system was developed with the extreme programming development method with system design using a unified modeling language, namely use case diagram, class diagram, and activity diagram. To assess the feasibility of the system, testing was carried out using the black-box method which resulted in an accuracy of 100%, so that this system was fit for use functionally.

TL;DR: A new method called Actors and Use Cases Size Estimation is proposed, based on the number of actors and use cases only, which led to a very significant reduction in errors when estimating the size of software systems compared to Use Case Points-based methods.
Abstract: Software size estimation represents a complex task, which is based on data analysis or on an algorithmic estimation approach. Software size estimation is a nontrivial task, which is important for software project planning and management. In this paper, a new method called Actors and Use Cases Size Estimation is proposed. The new method is based on the number of actors and use cases only. The method is based on stepwise regression and led to a very significant reduction in errors when estimating the size of software systems compared to Use Case Points-based methods. The proposed method is independent of Use Case Points, which allows the elimination of the effect of the inaccurate determination of Use Case Points components, because such components are not used in the proposed method.

TL;DR: 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: 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.

TL;DR: The study reviews and identifies similarity measurements of UML artifacts, with class diagram, sequence diagram, statechart diagram, and use case diagram being UML diagrams that are widely used as research objects for measuring similarity.
Abstract: Every piece of software uses a model to derive its operational, auxiliary, and functional procedures. Unified Modeling Language (UML) is a standard displaying language for determining, recording, and building a software product. Several algorithms have been used by researchers to measure similarities between UML artifacts. However, there no literature studies have considered measurements of UML diagram similarities. This paper presents the results of a systematic literature review concerning similarity measurements between the UML diagrams of different software products. The study reviews and identifies similarity measurements of UML artifacts, with class diagram, sequence diagram, statechart diagram, and use case diagram being UML diagrams that are widely used as research objects for measuring similarity. Measuring similarity enables resolution of the problem domains of software reuse, similarity measurement, and clone detection. The instruments used to measure similarity are semantic and structural similarity. The findings indicate opportunities for future research regarding calculating other UML diagrams, compiling calculation information for each diagram, adapting semantic and structural similarity calculation methods, determining the best weight for each item in the diagram, testing novel proposed methods, and building or finding good datasets for use as testing material.

TL;DR: A fault metric called use case fault metric (UCFM) for object-oriented systems using use case diagram and is built on the theory of Fault Tree Analysis (FTA) to address an important issue of measuring reliability of object- oriented systems during initial stages of software development.
Abstract: A significant quality factor reliability is an important requirement for all software systems. Reliability analysis and evaluation for a system is necessary for the success of these systems. This paper proposes a fault metric called use case fault metric (UCFM) for object-oriented systems using use case diagram and is built on the theory of Fault Tree Analysis (FTA). The goal is to address an important issue of measuring reliability of object-oriented systems during initial stages of software development. This goal is achieved by extending the model-driven software development process with the concept of Fault Tree Analysis (FTA). The Fault Tree analysis is performed in bottom-up way to compute quantitatively the proposed metric called UCFM. The proposed approach transforms the use case in an equivalent Fault Tree. This FTA is used to compute a metric that quantifies the probability of occurrence of faults in different use cases. The UCFM value is computed at use case, use case diagram and system level. The proposed metric is validated theoretically using measurement theory and practically using Kaner’s framework.

TL;DR: In this paper, a use case-based game modeling approach that extends the standard UML use case diagram is proposed to better represent game-related requirements and promote a common understanding of game requirements among game development teams.
Abstract: With the increase in market needs, game development teams are facing a high demand of creating new games every year. Although several methodologies and tools were introduced to support the game development life cycle, there is still a lack of evidence that these techniques improve game requirements understandability among development teams. The use of models in requirements engineering is considered a promising approach to support requirements elicitation, negotiation, validation, and management. In the context of game development, game designers argue that models are hard to learn and would restrict their creativity. In this paper, we introduce a novel use case-based game modeling approach that extends the standard UML use case diagram. The proposed technique allows for better representation of game-related requirements and promotes a common understanding of game requirements among game development teams. Our approach is implemented in a tool, called game use case modeling, and its applicability is demonstrated using four well-known games, Super Mario Bros, Tetris, Just Dance, and The Walking Dead. Moreover, in order to assess the perceived understandability, learnability, and usefulness of the proposed approach, we have conducted a survey involving 29 participants from the game development community. Results indicate a very satisfactory agreement regarding the added value of the proposed approach and a willingness of adoption by the game development community.

Abstract: This paper proposes a web-based application designed to help elementary school students who have difficulty learning online independently and also their parents who are currently having difficulty teaching their children to study at home online, especially at this time of difficulty with a pandemic outbreak like COVID-19; this time does not allow for physical meetings for the learning process in primary schools. In this paper, we only focus on mathematics because based on several other studies, it is very difficult and important to learn mathematics at the beginning of educational activities such as at the elementary school level. In this paper, the system is modeled using the Unified Modeling Language (UML) tool in the form of a use case diagram which is used to describe the proposed business process and uses class diagrams to describe the database model diagram. In this case, the class diagram is used to describe the data in the class diagram where each class refers to a table in the database. The web-based application user interface is shown at the end to show the communication between users and applications, where this web-based application is implemented using Personal Home Pages (PHP) as server programming and using MySQL to store database model designs. Moreover, for the Intelligent Tutoring System (ITS), content was created using the Cognitive Tutor Authoring Tools (CTAT) which is an authoring tool for learning mathematics created by Carnegie Mellon University. In the end, this web-based application is expected to be used and support teachers as a complement to online mathematics learning, especially during difficult times such as during the COVID-19 pandemic.

TL;DR: A systematic literature review based on two research questions and extensive quality assessment criteria includes studies that identify 30 primary studies from 410 studies spanned from 2000 to 2018 that explore the approaches that generate test cases from requirements.
Abstract: Software testing is an important and cost intensive activity in software development. The major contribution in cost is due to test case generations. Requirement-based testing is an approach in which test cases are derivative from requirements without considering the implementation’s internal structure. Requirement-based testing includes functional and nonfunctional requirements. The objective of this study is to explore the approaches that generate test cases from requirements. A systematic literature review based on two research questions and extensive quality assessment criteria includes studies. The study identifies 30 primary studies from 410 studies spanned from 2000 to 2018. The review’s nding shows that 53% of journal papers, 42% of conference papers, and 5% of book chapters’ address requirements-based testing. Most of the studies use UML, activity, and use case diagrams for test case generation from requirements. One of the significant lessons learned is that most software testing errors are traced back to errors in natural language requirements. A substantial amount of work focuses on UML diagrams for test case generations, which cannot capture all the system’s developed attributes. Furthermore, there is a lack of UML-based models that can generate test cases from natural language requirements by refining them in context. Coverage criteria indicate how efficiently the testing has been performed 12.37% of studies use requirements coverage, 20% of studies cover path coverage, and 17% study basic coverage.

TL;DR: In this paper, an approach to generate test cases from UML use case description is proposed, where a control flow graph and NLP table is generated based on a specific algorithm and then the test paths are generated from the NLP tables.
Abstract: One of the most significant phases of software development is software testing, because of its value in identifying mistakes and gaps in the early stages of program development. In the past, software testing was done manually, and this is a tiring and inaccurate process that carries with it errors and gaps and requires time, effort, and money. At present, testers tend to perform the testing process automatically, to save time, effort, and money, and to obtain accurate results. However, there are few research works on the aspect of generating test cases from requirements specification especially generate test cases from use case description. An Approach to Generate Test Cases from Use Case description is proposed in this paper that consists of several processes. The input is the use case description of the use case diagram, which is being used as a basis for the approach. In the next step, each software summary of UML use cases is utilized to extract the necessary information for the development of the control flow graph and NLP table. A control flow graph and NLP table will be generated based on a specific algorithm after that generate test paths based on a specific algorithm. Then, the test cases will be generated from the test paths and NLP table. The proposed approach will enhance the process of generation of test cases and increase the accuracy and efficiency.

TL;DR: In this article, a use case diagram UML model was used to describe the context and requirements of the EC system and the main feature in the system is the ability to visualize the electricity usage by allowing users select search category.
Abstract: This paper addresses the design of a use case diagram Unified Modelling Language (UML) model when developing an EC system. The EC system is an important aspect to be developed due to the increasing demand of the user needs. Currently, there are no such systems developed to provide the summarization of the average electrical usage in a bar chart graph layout, which makes it difficult to understand energy usage patterns and their impact on electricity bills each month. In addition, the Tenaga Nasional Berhad (TNB) online customer service system does not have any related feature to assist users with understanding their energy usage [5]. The EC system will be developed to overcome the above-mentioned problems, and to recommend other features to complement average user needs. Specifying the context and requirements of the EC system will use a use case diagram UML model. The use case diagram shows the scope of the system that will be developed. The main feature in the EC system is the ability to visualize the electricity usage by allowing users select search category. The selection of the search category can include a range of dates, for example by day or month or year, in displaying the results. Based on the output produced, the users can properly manage their usage of electricity in their house and reduce their electricity bills.

TL;DR: In this paper, the authors introduce semi-formal graphical system modeling language (SysML) diagrams sufficient for modeling and tracing safety requirements, in particular the SysML requirements diagram (req).
Abstract: The chapter introduces semi-formal graphical system modeling language (SysML) diagrams sufficient for modeling and tracing safety requirements. It builds on the previous chapter on the modeling and tracing of safety requirements using the unified modeling language (UML). The introduced minimum set of SysML diagrams and graphical diagram elements are sufficient to document system knowledge, to analyze system safety, and for requirements modeling and tracing. Being a multi-domain semi-formal language for systems and requirements specification, systems engineering and requirements tracing, it is argued that SysML is less abstract than UML while containing further diagrams that are well suited for efficient engineering graphical requirements modeling, in particular, the SysML requirements diagram (req). It is used together with the SysML block definition diagram (bdd), the SysML internal block diagram (ibd), the SysML activity diagram (act), the SysML use case diagram (uc), the SysML state machine diagram (stm), and the SysML sequence diagram (sd). For each diagram, typical applications and examples including figures are given how to use it for modeling safety requirements. The diagram types, bdd, ibd, stm, and act, are already sufficient for modeling most types of technical safety requirements when using a state machine approach that considers the structure and behavior of the socio-technical system. It is shown how this can be contextualized with the diagram types, uc and sd, to cover system application cases. The chapter provides examples mainly in the domain of embedded systems.

TL;DR: In this paper, a web application has been successfully created to facilitate interaction between users and doctors on electrocardiogram (ECG) data and the results of the user's ECG classification.
Abstract: Cardiovascular disease (CVD) is a disease caused by malfunctioning of the heart and blood vessels. Arrhythmias are a type of cardiovascular disease. Arrhythmia can be detected by reading the patient's electrocardiogram (ECG) data. A system is needed that can read the user's electrocardiogram data frequently and detect when an arrhythmic occurs. Therefore, it is necessary to create an interface that can visualize data both from ECG data and detection results by machine learning. The design method of this system is divided into 7 stages, namely: designing the user flow diagram, designing the model and controller, designing the entity-relationship diagram (ERD), designing the use case diagram, creating API specification, realizing the system, and testing the features. Data collection on the client side was carried out by testing conducted by the Google Chrome browser version 86.0.4240.198 and Apache JMeter 5.4.1. Based on the model that has been created and tested, it can be concluded that a web application has been successfully created to facilitate interaction between users and doctors on ECG data and the results of the user's ECG classification. These features have tested and have a functional percentage of 100%. On the server-side, the average CPU usage value were 86.27% for PHP, 4.77% for MariaDB, and 0.28% for Nginx. The average value of memory usage were 173.6 MB for PHP, 87.33 MB for MariaDB, and 7.90 MB for Nginx. Then, on the client-side, the more users who open the application at the same time, the value of the error ratio and response time would also increase. The system could handle 100 requests per second successfully, so application can handle 8,640,000 requests per day on the tested hardware specification.
