This paper presents a user study based log analysis of the search behavior of low-literacy users in the developing world. It is first step towards Web search personalization for such users, which has been hindered by a paucity of appropriate data for inducing effective user models that target the real problems in information access for low literacy user population. We demonstrate the variations...

Firms send short message services (SMS) to customers’ mobile phones to promote their products. Many firms personalize this content to increase the relevance of the recommendations and to avoid overloading users with too many messages. This research examines the effects of location-based personalization on users’ intentions to use personalized mobile SMS. We draw on motivational theories to deve...

Recommender systems have been increasingly adopted in the current Web environment, to facilitate users in efficiently locating items in which they are interested. However, most studies so far have emphasized the algorithm’s performance, rather than from the user’s perspective to investigate her/his decision-making behavior in the recommender interfaces. In this paper, we have performed a user s...

Web mapping systems and Geographic Information Systems (GIS) in general are widely used nowadays. However, there is a lack of models that describe how users interact with this kind of application and the workload imposed on servers. These models are important for performance evaluation and to direct the focus of the development to the points that will affect the most used operations and the mos...

Battery swapping mode (BSM) is an important method of supplying energy to electric vehicles, in which the battery swapping behavior of electric vehicle users affects significantly the charging behavior of the battery swapping station. To determine the impacts of a driver’s swapping behavior on the power grid and generation cost, this paper proposes an optimization charging mode (OCM) and simula...

Despite the increasing awareness of the importance of security for daily computer users, we see that many users still fail to behave securely when confronted with a security-related decision. In this paper, we introduce a new approach to security-related dialogs called Adaptive Security Dialogs (ASD). This approach is a combination of a new architecture and a new way of interacting with users t...

One of the most popular social networking sites in Brazil is Twitter, which is used by one in five people who have internet at home. Based on that, we investigated how information visualization techniques can improve the analysis of the behavior of Twitter users’. These studies were done through a set of standard visualization techniques implemented in an interactive system entitled DeepTwitter.

Recently WOM has become popular with the penetration of Internet and the popularity of social media, and attracted the attention of IS researchers. This study develops a model to explore the factors motivating e-service users’WOM behavior from the expectation confirmation paradigm together with trust. The research model was empirical tested with 543 valid responses from the online travel servic...
