We introduce a framework for adapting virtual keyboard to individual user behavior by modifying Gaussian spatial model use personalized key center offset means and, optionally, learned covariances. Through numerous real-world studies, we determine the importance of training data quantity and weights, as well number clusters into which group keys avoid overfitting. While past research has shown ...

This article studies tech mergers that involve a large volume of consumer data. The merger links the markets for data collection and application through consumption synergy. merger-specific efficiency gains exist in market due to synergy data-enabled personalization. Prices fall but generally rise as are extracted away personalized pricing. When is enough, can result monopolization both markets...

Personalization in information systems can be considered beneficial but also ethically and socially harmful. Like many other technologies, the uptake of personalization has been rapid, with inadequate consideration given to its effects. Personalization in e-learning systems also has potential for both harmful and beneficial outcomes, but less is known about its effects. The ethical and social h...

The growth of available personalization services and the heterogeneity in content and representation of therein exploited User Models (UMs), raise a need for a mechanism allowing to aggregate partial UMs generated by other services. Such a mechanism will allow reuse of partial UMs in multiple personalization services that may need it. This paper discusses the details of a decentralized mediator...

We show how personalization techniques can be exploited to implement more adaptive and effective information access systems in electronic publishing. We distinguish persistent (or long term) and ephemeral (or short term) personalization, and we describe how both of them can be profitably applied in information filtering and retrieval systems used, via a specialized Web portal, by physicists in ...

One important factor that determines the quality of web-based customer service is the ability of a firm’s website to provide individual caring and attention. In this sense, online vendors try to offer varieties of web-based personalization. However, many previous studies show that there is an obvious trade off between personalization and customer privacy. The main objective of this research is,...
