query by object interface for information Requirement Elicitation in m commerce
International Journal of Human-computer Interaction, 2006Co-Authors: Shapiee Abd Rahman, Subhash Bhalla, Tetsuya HashimotoAbstract:Information Requirement Elicitation (IRE) is essential in wireless Web service to elicit information Requirements through interactive choice prompts. This article presents a design of a high-level user interface for IRE, in the context of banking database queries by a mobile Web user. The prototype is based on the notion of a Query-By-Object approach of building a query using multiple user-level steps. The test prototype system uses the Mobile Information Devices Profile of the Java 2 Platform, Micro Edition, for a wireless front end, and a Java 2 Platform, Enterprise Edition, application server and an Object-Relational Database Management System at the back end. An empirical study conducted on the prototype has demonstrated that the proposed user interface is intuitive and simple to use. The proposed interface aims to eliminate ambiguities in users' communication by virtue of a step-by-step procedure. The main contributions of this interface are its simplicity to express a query and its expressive power.

developing the skills needed for Requirement Elicitation in global software development
International Conference on Enterprise Information Systems, 2008Co-Authors: Miguel Romero, Aurora Vizcaíno, Mario PiattiniAbstract:The Requirement Elicitation stage is that which is most critical in the development of a software product. However, this stage is not covered on teaching courses with the required depth, nor is invested the necessary time in training students and practitioners in these tasks. There is currently a trend towards global software development (GSD) which complicates the process of Elicitation Requirements since, for instance, communication is more difficult because stakeholders are geographically distributed. Moreover, the Elicitation in GSD involves a variety of characteristics that are not often taught in software engineering courses. This paper presents some of the most important factors which may affect Elicitation in GSD. Furthermore, we propose techniques with which to help students and software engineers to develop some of the skills needed to carry out the Elicitation

web services based security Requirement Elicitation
IEICE Transactions on Information and Systems, 2007Co-Authors: Carlos Gutierrez, Eduardo Fernandezmedina, Mario PiattiniAbstract:Web services (WS, hereafter) paradigm has attained such a relevance in both the academic and the industry world that the vision of the Internet has evolved from being considered as a mere repository of data to become the underlying infrastructure on which organizations' strategic business operations are being deployed [1]. Security is a key aspect if WS are to be generally accepted and adopted. In fact, over the past years, the most important consortiums of the Internet, like IETF, W3C or OASIS, have produced a huge number of WS-based security standards. Despite this spectacular growth, a development process that facilitates the systematic integration of security into all subprocesses of WS-based software development life-cycle does not exist. Eventually, this process should guide WS-based software developers in the specification of WS-based security Requirements, the design of WS-based security architectures, and the deployment of the most suitable WS security standards. In this article, we will briefly present a process of this type, named PWSSec (Process for Web Services Security), and the artifacts used during the Elicitation activity, which belongs to the subprocess WSSecReq aimed at producing a WS-based security Requirement specification.

IEEE ICCI - Cognitive-Based Rules as a Means to Select Suitable Groupware Tools
2006 5th IEEE International Conference on Cognitive Informatics, 2006Co-Authors: G.n. Aranda, Aurora Vizcaíno, Alejandra Cechich, Mario Piattini, Jose Jesus Castro-schezAbstract:Global software development projects have to deal with a variety of challenges with respect to communication and control. For this reason, processes that are crucially based on communication, such as Requirement Elicitation, have to be specially rethought to minimize critical situations. As Requirement Elicitation is a human-centred process, we propose using techniques from the field of cognitive psychology to define a new approach towards it. In short, we intend to reduce problems in communication by selecting a suite of Elicitation techniques and groupware tools, according to stakeholders' preference in styles. In this article we introduce our approach and show the generation process of a set of preference rules of groupware tools.

ICCSA (1) - A cognitive perspective for choosing groupware tools and Elicitation techniques in virtual teams
Computational Science and Its Applications – ICCSA 2005, 2005Co-Authors: Gabriela N. Aranda, Aurora Vizcaíno, Alejandra Cechich, Mario PiattiniAbstract:Nowadays groupware tools, as well as Requirement Elicitation techniques, are chosen without a clear strategy that takes into account stakeholders' characteristics. When the chosen technology is not appropriate for all the group members it might affect their participation and the quality of the Requirement Elicitation process itself. In order to improve communication, and therefore stakeholders' participation, we propose choosing an appropriate set of groupware tools and Elicitation techniques according to stakeholders' preferences. This paper presents a prototype tool that makes a selection based on cognitive techniques.

towards a cognitive based approach to distributed Requirement Elicitation processes
WER, 2005Co-Authors: Gabriela N. Aranda, Aurora Vizcaíno, Alejandra Cechich, Mario PiattiniAbstract:Distance between stakeholders working on a global software development project introduces problems in communication and control. Processes like Requirements Elicitation, where communication is crucial, have to be specially rethought in order to deal with these problems. As the Requirement Elicitation is a human-centred process, we propose using techniques from the field of cognitive psychology to define a new approach for it. Our goal is reducing problems in communication by proposing the most suitable Elicitation techniques according to stakeholders’ preferences. In this paper, we introduce our approach and illustrate how cognitive styles might be used to improve Elicitation.

enhanced query by object approach for information Requirement Elicitation in large databases
International Conference on Big Data, 2012Co-Authors: Ammar Yasir, Mittapally Kumara Swamy, Polepalli Krishna Reddy, Subhash BhallaAbstract:Information Requirement Elicitation (IRE) recommends a framework for developing interactive interfaces, which allow users to access database systems without having prior knowledge of a query language. An approach called ‘Query-by-Object’ (QBO) has been proposed in the literature for IRE by exploiting simple calculator like operations. However, the QBO approach was proposed by assuming that the underlying database is simple and contains few tables of small size. In this paper, we propose an enhanced QBO approach called Query-by-Topics (QBT), for designing calculator like user interfaces for large databases. We use methodologies for clustering database entities and discovering topical structures to represent objects at a higher level of abstraction. The QBO approach is then enhanced to allow users to query by topics (QBT). We developed a prototype system based on QBT and conducted experimental studies to show effectiveness of the proposed approach.

user intention recognition and Requirement Elicitation method for conversational ai services
arXiv: Artificial Intelligence, 2020Co-Authors: Junrui Tian, Zhongjie Wang, Min LiuAbstract:In recent years, chat-bot has become a new type of intelligent terminal to guide users to consume services. However, it is criticized most that the services it provides are not what users expect or most expect. This defect mostly dues to two problems, one is that the incompleteness and uncertainty of user's Requirement expression caused by the information asymmetry, the other is that the diversity of service resources leads to the difficulty of service selection. Conversational bot is a typical mesh device, so the guided multi-rounds Q$\&$A is the most effective way to elicit user Requirements. Obviously, complex Q$\&$A with too many rounds is boring and always leads to bad user experience. Therefore, we aim to obtain user Requirements as accurately as possible in as few rounds as possible. To achieve this, a user intention recognition method based on Knowledge Graph (KG) was developed for fuzzy Requirement inference, and a Requirement Elicitation method based on Granular Computing was proposed for dialog policy generation. Experimental results show that these two methods can effectively reduce the number of conversation rounds, and can quickly and accurately identify the user intention.
