    Extending the Coverage of DBpedia Properties using Distant Supervision over Wikipedia

    DBpedia is a semantic web project aiming to extract structured data from Wikipedia articles. Due to the increasing number of resources linked to it, DBpedia plays a central role in the linked open data community. Currently, the information contained in DBpedia is mainly collected from Wikipedia info-boxes, a set of...

    Capturing Information Flows Inside Android and Qemu Environments

    The Smartphone market has grown so wide that it assumed a strategic relevance. Today the most common Smartphone OSs are Google's Android and Apple's iOS. The former is particularly interesting due to its open source nature that allows everyone to deeply inspect every aspect of the OS. Android source code...

    State Space Exploration of RT Systems in the Cloud

    The growing availability of distributed and cloud computing frameworks make it possible to face complex computational problems in a more effective and convenient way. A notable example is state-space exploration of discrete event systems specified in a formal way. The exponential complexity of this task is a major limitation to...

    Semantic Data Clouding Over the Webs

    Very often, for business or personal needs, users require retrieving, in a very fast way, all the available relevant information about a focused target entity, in order to take decisions, organize business work, plan future actions. To answer this kind of \"Entity\"-driven user needs, a huge multiplicity of web resources...

    Running Business Applications in the Cloud: A Use Case Perspective

    Cloud computing leverages the use of abstracted resources. However, migrating an industrial application to well-known Cloud solutions such as EC2 might be complex and low-level expertise is indeed needed. In this use case the authors present a methodology, based on practical experience matured on the ground that allows service providers...

    An In-Depth Analysis of the SCTP Behavior in Mobile Ad Hoc Networks

    SCTP is a reliable transport layer protocol with some interesting features for applications development in ad hoc networks. Among the others, multi-streaming is one of the most interesting capabilities, that allows to increase the throughput, because it reduces the Head-Of-Line (HOL) blocking effects. In this paper, the authors evaluate the...

    A Semantic Clouding Approach for Cross-Webs Interoperability

    The classical vision of the web as a merely publishing environment for information-consuming users is being replaced by a plural vision where multiple webs, like web 2.0, social web, and semantic web, co-exist and interoperate to make information sharing more effective and socially pervasive. In this paper, the authors propose...

    Text-Driven Avatars Based on Artificial Neural Networks and Fuzzy Logic

    The authors discuss a new approach for driving avatars using synthetic speech generated from pure text. Lip and face muscles are controlled by the information embedded in the utterance and its related expressiveness. Rule-based, text-to-speech synthesis is used to generate phonetic and expression transcriptions of the text to be uttered...

    How to Enhance Cloud Architectures to Enable Cross-Federation

    The near future evolution of the cloud computing can be hypothesized in three subsequent stages: stage 1 "Monolithic" (now), cloud services are based on independent proprietary architectures; stage 2 "Vertical supply chain", cloud providers will leverage cloud services from other providers; stage 3 "Horizontal federation", smaller, medium, and large cloud...

    CLEVER: A CLoud-Enabled Virtual EnviRonment

    A cloud-enabled virtual environment called CLEVER is proposed in this paper. CLEVER aims to design a Virtual Infrastructure management layer to simplify the access and administration of private/hybrid clouds. It also provides simple and easily accessible interfaces to interact with different "Interconnected" cloud computing infrastructures and successfully deploy Virtual Machines...

    From Grids to Clouds - Shift in Security Services Architecture

    Nowadays, the notion of Cloud computing is making significant head-way in the computing landscape. Its emergence was initially seen as a complementary technology to address the major shortcoming of the Grid technology. However, the business push to Cloud computing paradigm resulted in a more sophisticated concept of rent-a-technology that enabled...

    Privacy-Enhanced Location-Based Access Control

    Advancements in location technologies reliability and precision are fostering the development of location-based services that make use of the location information of users. An increasingly important category of such services is represented by Location-Based Access Control (LBAC) systems that integrate traditional access control mechanisms with access conditions based on the...

    A Middleware Architecture for Integrating Privacy Preferences and Location Accuracy

    Location-Based Access Control (LBAC) systems support the evaluation of conditions on locations in the enforcement of access control policies. The ability to evaluate conditions on a set of authorized locations has a number of well-known advantages, including enriching access control expressiveness. However, when locations are used in combination with personal...
