Due to the high popularity of social bookmarking systems, a large amount of metadata is available. Aggregating the metadata belonging to one user results in an user profile similar to those often used in Information Filtering. This paper shows how to create user profiles from tagging data. We present the Add-A-Tag algorithm for profile construction which(More)
The ‘SemanticLIFE’ system is designed to store, manage and retrieve ones lifetime’s information entities. It enables the acquisition and storage of data while giving annotations to email messages, browsed web pages, phone calls, images, contacts, life events and other resources. ‘SemanticLIFE’ also provides intuitive and effective search mechanism based(More)
Modern lifestyle has created a new species of tourist who makes several short city trips per year and uses high-tech equipment. LoL@ (local location assistant) is a location-based multimedia UMTS (universal mobile telecommunications system) application that aims at supporting this class of tourist. LoL@ offers maps, localization, and routing functionality,(More)
Although the ant metaphor has been successfully applied to routing of data packets both in wireless and fixed networks, little is known yet about its appropriateness for search in peer-to-peer environments. This paper presents SemAnt, a distributed content-based routing algorithm based on the Ant Colony Optimization meta-heuristic and adapted for deployment(More)
UMTS services integrate mobile communications and the Internet, based on a powerful and standardized service architecture. To achieve a positive user experience, careful resource planning, service and protocol design are necessary. After dealing with some fundamental issues of UMTS services, this paper presents LoL@, the Local Location Assistant. It is a(More)

Although the ant metaphor has been successfully applied to routing of data packets both in wireless and fixed networks, little is yet known about its applicability to the task of query routing in peer-to-peer environments. This work presents SemAnt, an algorithm for distributed query routing based on the Ant Colony Optimization meta-heuristic. The(More)
This paper presents the design and evaluation of an ant-based approach to query routing in peer-to-peer networks. After pointing out how to employ the ant metaphor in peer-to-peer networks, we conduct a thorough evaluation of the impact of different settings for the configurable parameters present in ant algorithms on the performance values. In particular,(More)
