– In this extended abstract we present a preliminary (and at this point incomplete) analysis over the largest publicly accessible web dataset: the Common Crawl Corpus. We measure nine web characteristics from two levels of granularity using MapReduce and we comment on the initial observations which will be concluded with the final version of the paper. To(More)
In this paper, we describe the design and implementation of an audio wiki application accessible via both the Public Switched Telephone Network (PSTN) and the Internet. The application exploits mature World Wide Web Consortium (W3C) standards such as VoiceXML, Speech Synthesis Markup Language (SSML) and Speech Recognition Grammar Specification (SRGS)(More)
Web personalization is an elegant and flexible process of making a web site responsive to the unique needs of each individual user. Data that reflects user preferences and likings, comprising therefore a user profile, are gathered to an adaptive web site in a non transparent manner. This situation however raises serious privacy concerns to the end user.(More)

Automatic surveillance of a scene in a broad sense comprises one of the core modules of pervasive applications. Typically, multiple cameras are installed in an area to identify events through image processing techniques, which however present limitations in terms of object occlusion, noise, lighting conditions, image resolution and computational cost.

With the proliferation of Web 2.0 applications, colla-borative learning has gathered a lot of attention due its potentiality in the e-learning field. Forums, Wikis and Blogs for example are only some of the applications that exploit the collaborative nature of e-learning. However, these applications are originally designed for access from desktop systems(More)
