A scientific conference is a type of event for which the structured program is generally known in advance. The Semantic Web community has setup a so-called Semantic Web dog food server that exposes structured data about the detailed program of more and more conferences and their sub-events (e.g. sessions). Conferences are also events that trigger a(More)
The widely used paradigm of faceted browsing is limited by the fact that only one query and result set are displayed at a time. This demonstrator introduces an interaction design for <i>parallel faceted browsing</i> that makes it easy for a user to construct and view the results of multiple interrelated queries. The paradigm offers general benefits for a(More)
A scientific conference is a type of event where attendees have a tremendous activity on social media platforms. Participants tweet or post longer status messages, engage in discussions with comments, share slides and other media captured during the conference. This information can be used to generate informative reports of what is happening, where (which(More)
The data exploration paradigm of faceted browsing has been applied successfully in many systems that provide access to either semantic data or more conventional databases. A general limitation is that the user can examine the results for only one query (i.e., one combination of facet value constraints) at a time. But there are many everyday tasks for which(More)
An ever increasing amount of event-centric knowledge is spread over multiple social services, either materialized as calendar of events or illustrated by media items shared by people. Crawling data and mining in real-time events connection between these heterogeneous services is a key challenge to enhance events views. In this paper, we present EventMedia,(More)
To cope with the massive growth of semantic data streams, several RDF Stream Processing (RSP) engines have been implemented. The efficiency of their throughput, latency and memory consumption can be evaluated using available benchmarks such as LSBench and CityBench. Nevertheless, these benchmarks lack an in-depth performance evaluation as some measurement(More)
Many online services provide functionalities for sharing one’s participation and captured media at real-world events. In a previous work [3], we constructed the EventMedia dataset aggregating heterogeneous sources of information and producing linked data. In this work, we carry out an event-oriented data reconciliation experiment in the web of data, and we(More)
Event and media services have recently witnessed a rapid growth driving the way people explore information of interest. A significant amount of social calendars, mediamemes and background knowledge are daily created on various platforms, conveying event clues or past users experience. Mining, in real-time, the connection of these distributed data fragments(More)
