An ever increasing amount of event-centric knowledge is spread over multiple web sites, either materialized as calendar of past and upcoming events or illustrated by cross-media items. This opens an opportunity to create an infrastructure unifying event-centric information derived from event directories, media platforms and social networks. In order to(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)
Converging Web and Telco services is one of the most interesting and valuable challenge that both Web providers and Telco operators will be facing during the next few years. Indeed, recent evolutions like smartphones' enhanced web-browsing capabilities (e.g. IPhone) and the technical incursion of Web2.0 main actors in the Telco world (e.g. Android) points(More)
A scientific conference is a type of event for which the struc-tured 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)
Due to the growing need to timely process and derive valuable information and knowledge from data produced in the Semantic Web, RDF stream processing (RSP) has emerged as an important research domain. In this paper, we describe the design of an RSP engine that is built upon state of the art Big Data frameworks, namely Apache Kafka and Apache Spark.(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 City- Bench. Nevertheless, these benchmarks lack an in-depth performance evaluation as some measurement(More)
