Real-time web crawler detection
(2011)
In this paper we present a methodology for detecting web crawlers in real time. We use decision trees to classify requests in real time, as originating from a crawler or human, while their session is ongoing. For this ...
A socio-aware decentralized topology construction protocol
(Institute of Electrical and Electronics Engineers Inc., 2016)
Decentralized Online Social Networks (DOSNs) offer an alternative to the usual centralized solutions, that promises to preserve more control of a user's data to the user herself. An important aspect in the design of DOSNs ...
Continuous all k-nearest-neighbor querying in smartphone networks
(2012)
Consider a centralized query operator that identifies to every smart phone user its k geographically nearest neighbors at all times, a query we coin Continuous All k-Nearest Neighbor (CAkNN). Such an operator could be ...
MANDOLA: A Big-Data Processing and Visualization Platform for Monitoring and Detecting Online Hate Speech
(2020)
In recent years, the increasing propagation of hate speech in online social networks and the need for effective counter-measures have drawn significant investment from social network companies and researchers. This has ...
Feel the world: A mobile framework for participatory sensing
(2013)
Nowadays, smartphones have almost replaced basic feature phones all over the world. Today's smartphones come equipped with an increasing set of embedded sensors, computational and communication resources. All these gave ...
Topic 1: Support tools and environments
(2012)
Despite an impressive body of research, parallel and distributed computing remains a complex task prone to subtle software issues that can affect both the correctness and the performance of the computation. It is interesting ...
Scheduling workflows with budget constraints
(Springer Science and Business Media, LLC, 2007)
Grids are emerging as a promising solution for resource and computation demanding applications. However, the heterogeneity of resources in Grid computing, complicates resource management and scheduling of applications. In ...
Experience with the International Testbed in the CrossGrid Project
(2005)
The International Testbed of the CrossGrid Project has been in operation for the last three years, including 16 sites in 9 countries across Europe. The main achievements in installation and operation are described, and ...
First prototype of the CrossGrid testbed
(2004)
The CrossGrid project is developing new grid middleware components, tools and applications with a special focus on parallel and interactive computing. In order to support the development effort and provide a test infrastructure, ...
Clustering attributed multi-graphs with information ranking
(2015)
Attributed multi-graphs are data structures to model realworld networks of objects which have rich properties/attributes and they are connected by multiple types of edges. Clustering attributed multigraphs has several ...
