We present HAMLET, a suite of principles, scoring models and algorithms to automatically propagate metadata along edges in a document neighborhood. As a showcase scenario we consider tag prediction in community-based Web 2.0 tagging applications. Experimen ...

Today the problem of semantic interoperability in information search on the Internet is solved mostly by means of centralization, both at a sys-tem and at a logical level. This approach has been successful to a certain extent. Peer-to-peer systems as a new brand of system architectures indicate that the principle of decentralization might offer new solutions to many problems that scale well to very large numbers of users. In this paper we outline how the peer-to-peer system architectures can be applied to t

P2P content distribution networks have become extremely popular on the Internet. Due to their self-organization properties, they suffer from the lack of control to balance the load among peers for contents of different popularity. In this paper, we define and analyze a fully decentralized architecture to support replication of popular media content in a peer-to-peer network. We show that by exploiting local knowledge only, this method achieves a nearoptimal behavior with respect to response time in a scenar

The proliferation of digital camera devices (stand-alone or combined with cell phones), new protocols such as MMS and the desire of people to com-municate and share their experience call for new systems to support these needs in new Internet-scale infrastructures. In this paper we outline our plans for an Internet-scale P2P system that enables users to share (globally or only within a group) and efficiently locate photographs based on semi-automatically provided meta-information (by the devices and the user

We tackle the problem of improving the relevance of automatically selected tags in large-scale ontology-based information systems. Contrary to traditional settings where tags can be chosen arbitrarily, we focus on the problem of recommending tags (e.g., co ...

Social media has become an important instrument for running various types of public campaigns and mobilizing people. Yet, the dynamics of public campaigns on social networking platforms still remain largely unexplored. In this paper, we present an in-depth ...

Warehouses must maintain a number of spatial constraints concerning the safe handling of hazardous materials. In this paper, we address the problem of automated monitoring of spatial constraints as pallets are moved on forklifts by human operators. We prop ...

We consider the problem of analytically evaluating semantic interoperability in large-scale networks of schemas interconnected through pairwise schema mappings. Our heuristics are based on a graph-theoretic framework capturing important statistical propert ...

Social media have become one of the key platforms to support the debate on climate change. In particular, Twitter allows easy information dissemination when running environmental campaigns. Yet, the dynamics of these campaigns on social platforms still rem ...

With new standards like RDF or OWL paving the way for the much anticipated semantic web, a new breed of large scale semantic systems is about to appear. Even if research on semantic reconciliation methods is abundant, it is not clear how interoperable very large scale semantic systems can be. This paper represents a first effort towards analytically analyzing semantic interoperability in the large: By adapting a recent graph-theoretic framework, we examine the dynamics of large scale semantic systems and de
