Recommender systems have been actively and extensively studied over past decades. In the meanwhile, the boom of Big Data is driving fundamental changes in the development of recommender systems. In this paper, we propose a dynamic intention-aware recommender system to beŠer facilitate users to €nd desirable products and services. Compare to prior work, our proposal possesses the following advan...

Technological developments and governments’ understanding of what citizens need usually determine the design of public online services. For successful implementation of e-Government services, governments have to place the user in the center of future developments, understand what citizens need and measure what increases citizens’ willingness to adopt e-government services. The paper uses the Te...

Adoption studies on electronic tax-filing system using data from emerging nations are rare. The present paper studies the influence of perceived ease of use, perceived usefulness, and user satisfaction on taxpayers’ behavioral intentions to adopt electronic tax filing services in an emerging economy. For this study, constructs from Theory of Planned Behavior (Ajzen, 1985, 1991), Technology Acce...

Successful User Interface (UI) designs often utilise insight into tasks by studying user interactions, intentions, and expectations. User interaction itself amounts to the interplay of cognition and information processing as embodied by task routines or sequences that are commonly captured in a TA. This chapter will focus on procedures for uncovering cognitive processes relative to user goals a...

Modelling processes and guiding their enactment are key issues in research on the formalisation of methods. This paper presents a formalism called map for specifying process models. Process maps describe the users intentions. Each intention can be fulfilled through different strategies. The user is free in choosing the technique he wants to apply. Process maps do not constrain the user into a p...

Assessment of exposure to airborne endotoxins has been studied for several years, especially in occupational environments, but a large number of procedures are used for sampling and analysis. This lack of standardization makes it very difficult to compare results and set internationally accepted threshold limit values (TLVs) or occupational exposure limits (OELs) for endotoxin exposure. This pa...

Traditional e-learning systems support " one-way " communication. Teachers provide knowledge for learners, but they are unable to use a student's learning experiences to benefit the class as a whole. To address these problems, this study explores e-learning success factors via the design and evaluation of an e-learning 2.0 system. This study develops a theoretical model to assess user satisfact...

Many research have been focusing on how to match the textual query with visual images and their surrounding texts or tags for Web image search. The returned results are often unsatisfactory due to their deviation from user intentions. In this paper, we propose a novel image ranking approach to web image search, in which we use social data from social media platform jointly with visual data to i...

Fitness assignment is one of the biggest challenges in evolutionary art. Interactive evolutionary computation approaches put a significant burden on the user, leading to human fatigue. On the other hand, autonomous evolutionary art systems usually fail to give the users the opportunity to express and convey their artistic goals and preferences. Our approach empowers the users by allowing them t...

User experience (UX) professionals' attempts to address social values as a part of their work practice can overlap with tactics contest, resist, or change the companies they for. This paper studies that take place in this overlap, where UX professionals try re-shape embodied and promoted by companies, addition technical systems products produce. Through interviews working at large U.S.-based te...
