A theoretical framework and empirical examination of the effects of foreign and translated interface language

Given the increased globalization and popularization of computer applications, translating a system's human interface into the local language has become a major consideration for software vendors and distributors. In this paper, we suggest a theoretical framework for the study of user interface translation. The framework includes recognizing vendors' and users' costs of, and benefits from, software translation. An experiment was conducted, based on this framework, to test user performance and preferences regarding interface translations. The experiment manipulated the translation of two interface components: documentation language and manipulation language. The results indicate that users are sensitive to different combinations of interface translation in a way that is commensurate with the instruction-following process (Terwilliger and Polson 1997). Users performed best when a fully translated interface was used and worst when only the manipulation language was translated. Users' preferences were in line with their performance, indicating that a cost benefit approach can serve as a promising starting point to the study of interface translation.     

A theoretical framework for simulated annealing

Simulated Annealing has been a very successful general algorithm for the solution of large, complex combinatorial optimization problems. Since its introduction, several applications in different fields of engineering, such as integrated circuit placement, optimal encoding, resource allocation, logic synthesis, have been developed. In parallel, theoretical studies have been focusing on the reasons for the excellent behavior of the algorithm. This paper reviews most of the important results on the theory of Simulated Annealing, placing them in a unified framework. New results are reported as well.

Hypertext functionality: A theoretical framework

This article presents a theoretical framework useful for understanding the functionality of Hypertext systems in terms of their ability to satisfy cognitive requirements for expressing concepts and their relationships. This theoretical framework is derived from a re‐interpretation of Guilford's theory of the Structure of Intellect.     

Combining classifiers: A theoretical framework

The problem of classifier combination is considered in the context of the two main fusion scenarios: fusion of opinions based on identical and on distinct representations. We develop a theoretical framework for classifier combination for these two scenarios. For multiple experts using distinct representations we argue that many existing schemes such as the product rule, sum rule, min rule, max rule, majority voting, and weighted combination, can be considered as special cases of compound classification. We then consider the effect of classifier combination in the case of multiple experts using a shared representation where the aim of fusion is to obtain a better estimate of the appropriatea posteriori class probabilities. We also show that the two theoretical frameworks can be used for devising fusion strategies when the individual experts use features some of which are shared and the remaining ones distinct. We show that in both cases (distinct and shared representations), the expert fusion involves the computation of a linear or nonlinear function of thea posteriori class probabilities estimated by the individual experts. Classifier combination can therefore be viewed as a multistage classification process whereby thea posteriori class probabilities generated by the individual classifiers are considered as features for a second stage classification scheme. Most importantly, when the linear or nonlinear combination functions are obtained by training, the distinctions between the two scenarios fade away, and one can view classifier fusion in a unified way.

Combining natural language with direct manipulation: the conceptual framework for a hybrid human-computer interface

Abstract

This paper describes the development of a conceptual model of an interaction system for future human-computer interaction. It is suggested that an integrated system is the most promising solution for diverse users and tasks. A ‘ hybrid interaction system’ is considered, which tries to efficiently direct manipulation, menu selection, and natural language. The mechanism of the natural language interface module is described in more detail. Finally, the allocation of functionalities for generalized tasks on the conceptual model is considered from the taxonomic approach.     

A management system for foreign language tests

Two of the more difficult and time-consuming problems facing the foreign language teacher is the preparation and administration of quizzes and examinations. Since testing is an integral part of teaching, the problem of designing and implementing accurate, valid examinations is a crucial one. Computers are known for their speed, accuracy and repeatability. The use of the computer solves several problems inherent in test preparation. One can, given a well designed program, relegate the tasks of item selection and the producing of duplicating masters to the computer. Of course, the test items must be entered on the machine originally and proof-read, but once the procedure is done, the computer becomes an ideal storage medium: editing the items is quickly and easily performed. And, since all test items are stored in one place, it is possible to improve the test quality (both by increasing the quality of the test items themselves and by reducing the number of typographical errors) through repeated use with students and the subsequent modification of the computers “item bank” based on the students' performance on the tests.

A multiscale empirical modeling framework for system identification

A multiscale system identification methodology is presented and discussed, that extends, in a systematic way, the classical board of single-scale system identification tools to a multiscale context. The proposed approach is built upon a wavelet-based multiscale decomposition in a receding horizon sliding window that always includes the last measured values, in order to make it adequate for on-line use. Several examples are presented that illustrate different features of the multiscale modeling framework, such as its improved ability to perform prediction in output variables having most of its energy concentrated at intermediate or coarser time scales when compared to input variables, and its intrinsic smoothing capability.     

Quitting the use of a habituated hedonic information system: a theoretical model and empirical examination of Facebook users

Much research has been devoted to the early adoption and the continued and habituated use of information systems (IS). Nevertheless, less is known about quitting the use of IS by individuals, especially in habituated hedonic settings, that is, IS discontinuance. This study focuses on this phenomenon, and argues that in hedonic IS use contexts (1) IS continuance and discontinuance can be considered simultaneously yet independently by current users, and that (2) IS continuance and discontinuance drivers can have differential effects on the respective behavioral intentions. Specifically, social cognitive theory is used to point to key unique drivers of website discontinuance intentions: guilt feelings regarding the use of the website and website-specific discontinuance self-efficacy, which counterbalance the effects of continuance drivers: habit and satisfaction. The distinctiveness of continuance and discontinuance intentions and their respective nomological networks, as well as the proposed research model, were then empirically validated in a study of 510 Facebook users. The findings indicate that satisfaction reduces discontinuance intentions directly and indirectly through habit formation. However, habit can also facilitate the development of ‘addiction’ to the use of the website, which produces guilt feelings and reduces one’s self-efficacy to quit using the website. These factors, in turn, drive discontinuance intentions and possibly the quitting of the use of the website.     

A theoretical framework for an intelligent design catalogue

Product catalogues constitute a valuable source of information for engineers engaged in design activities. Unfortunately, these catalogues provide only limited support to engineers in the earlier, conceptual stages of design. This research proposes the intelligent design catalogue consisting of a virtual design environment linked to catalogues of standard components. Engineers develop their design concepts within the virtual environment and refer to the catalogues as these concepts are refined. The selected components are assembled within the design environment. The intelligent design catalogue provides search aids as well as assessment tools. The theoretical framework draws on several engineering areas. Manufacturing demonstrates how process plans can be developed in a virtual environment independently of the machines on the shop floor just as products can be conceptually designed independently of the standard components available. The standard components themselves can be grouped borrowing from classification schemes of group technology. Object-oriented programming (OOP) provides an environment for the development of the software that runs the intelligent design catalogue. As the objects of OOP parallel standard components, OOP also serves as a design paradigm after which the catalogue can be modelled. Design theory suggests frameworks for developing a (semi-) hierarchical structure for cataloguing parts.     

A framework for empirical evaluation of conceptual modeling techniques

The paper presents a framework for the empirical evaluation of conceptual modeling techniques used in requirements engineering. The framework is based on the notion that modeling techniques should be compared via their underlying grammars. The framework identifies two types of dimensions in empirical comparisons—affecting and affected dimensions. The affecting dimensions provide guidance for task definition, independent variables and controls, while the affected dimensions define the possible mediating variables and dependent variables. In particular, the framework addresses the dependence between the modeling task—model creation and model interpretation—and the performance measures of the modeling grammar. The utility of the framework is demonstrated by using it to categorize existing work on evaluating modeling techniques. The paper also discusses theoretical foundations that can guide hypothesis generation and measurement of variables. Finally, the paper addresses possible levels for categorical variables and ways to measure interval variables, especially the grammar performance measures.     

A theoretical framework for multiple neural network systems

Multiple neural network systems have become popular techniques for tackling complex tasks, often giving improved performance compared to single network systems. For example, modular systems can provide improvements in generalisation through task decomposition, whereas multiple classifier and regressor systems typically improve generalisation through the ensemble combination of redundant networks. Whilst there has been significant focus on understanding the theoretical properties of some of these multi-net systems, particularly ensemble systems, there has been little theoretical work on understanding the properties of the generic combination of networks, important in developing more complex systems, perhaps even those a step closer to their biological counterparts. In this article, we provide a formal framework in which the generic combination of neural networks can be described, and in which the properties of the system can be rigorously analysed. We achieve this by describing multi-net systems in terms of partially ordered sets and state transition systems. By way of example, we explore an abstract version of learning applied to a generic multi-net system that can combine an arbitrary number of networks in sequence and in parallel. By using the framework we show with a constructive proof that, under specific conditions, if it is possible to train the generic system, then training can be achieved by the abstract technique described.     

Neverlang: A framework for feature-oriented language development

Reuse in programming language development is an open research problem. Many authors have proposed frameworks for modular language development. These frameworks focus on maximizing code reuse, providing primitives for componentizing language implementations. There is also an open debate on combining feature-orientation with modular language development. Feature-oriented programming is a vision of computer programming in which features can be implemented separately, and then combined to build a variety of software products. However, even though feature-orientation and modular programming are strongly connected, modular language development frameworks are not usually meant primarily for feature-oriented language definition. In this paper we present a model of language development that puts feature implementation at the center, and describe its implementation in the Neverlang framework. The model has been evaluated through several languages implementations: in this paper, a state machine language is used as a means of comparison with other frameworks, and a JavaScript interpreter implementation is used to further illustrate the benefits that our model provides.     

A framework for an integrated unified modeling language

The unified modeling language (UML) is one of the most commonly used modeling languages in the software industry. It simplifies the complex process of design by providing a set of graphical notations, which helps express the objectoriented analysis and design of software projects. Although UML is applicable to different types of systems, domains, methods, and processes, it cannot express certain problem domain needs. Therefore, many extensions to UML have been proposed. In this paper, we propose a framework for integrating the UML extensions and then use the framework to propose an integrated unified modeling language-graphical (iUML-g) form. iUML-g integrates the existing UML extensions into one integrated form. This includes an integrated diagram for UML class, sequence, and use case diagrams. The proposed approach is evaluated using a case study. The proposed iUML-g is capable of modeling systems that use different domains.     

A spoken language interface with a mobile robot

We describe a spoken dialogue interface with a mobile robot, which a human can direct to specific locations, ask for information about its status, and supply information about its environment. The robot uses an internal map for navigation, and communicates its current orientation and accessible locations to the dialogue system. In this article, we focus on linguistic and inferential aspects of the human–robot communication process.

A theoretical framework to improve the quality of manually acquired data

We present a framework for organisations to prevent errors in data entry. It states that data entry errors can be prevented by a strong intention of data producers to enter data correctly and by a high task-technology fit. Two empirical studies support the framework and demonstrate that a high task-technology fit is relatively more important than the data producers’ intention. The framework refines the theory of planned behaviour, and extends the explanatory domain of the task-technology fit construct. The empirical evidence underlines the importance of the task-technology fit construct, an often-neglected construct in information systems research.
