During phases of transient connectivity, sensor nodes receive a substantial number of corrupt packets. These corrupt packets are generally discarded, losing the sent information and wasting the energy put into transmitting and receiving. Our analysis of one year’s data from an outdoor sensor network deployment shows that packet corruption follows a distinct pattern that is observed on all links...

This study investigated the factors influencing trust in travel-related CGM and the degree to which trust affects the benefits and impacts of using CGM when planning pleasure trips. An online survey of US Internet users was conducted with a total of 1170 individuals responding to questions regarding their perceptions and use of CGM for travel planning. The findings show that CGM use is widespre...

Our work demonstrates how proactive context-aware service provisioning has been deployed in the DYNAMOS System to address the needs of typical recreational boaters. We show by means of several usage scenarios how our system constantly provides mobile users with services that fit them in their current context. Furthermore, the system enables users to create and to share with peers user-generated...

We document the creation of a new set of OpenMath content dictionaries to support the expression of quantities and units under the International System of Units (SI). While preserving many of the concepts embodied in the original content dictionaries, these new content dictionaries provide a foundation for quantities and units that is compliant with international standards. We respond to questi...

Assessing the quality of user generated content is an important problem for many web forums. While quality is currently assessed manually, we propose an algorithm to assess the quality of forum posts automatically and test it on data provided by Nabble.com. We use state-of-the-art classification techniques and experiment with five feature classes: Surface, Lexical, Syntactic, Forum specific and...

This article presents the potential for new business models in the context of user-generated content and services in the mobile environment. The approach is based on the concept of a new platform that incorporates multiple (mobile) network providers as well as private and commercial third party content and service providers. The potential for gaining and sharing revenues among the different par...

We introduce our methodology for collecting tweets and identifying event-related actionable information using key terms and inflections. The vast amount of user-generated content makes it challenging to detect relevant information. Therefore, we aim to facilitate extracting morphological, syntactic, and semantic features of a key term semiautomatically. The results of our study show that handli...

Reputation is an essential component of destination competitiveness. The analysis of UGC (“explicit” popularity) and of the engagement generated by these comments (“implicit” popularity”) is usually conducted separately. Monitoring the online performance of a destination require a more comprehensive approach, which combines the capacity to attract tourists’ reviews and to enhance potential visi...
