A Decentralized Recommendation System Based on Self-organizing Partnerships

چکیده
Small World patterns have been found in many social and natural networks, and even in Peer-to-Peer topologies. In this paper, we analyze File Sharing applications that aggregate virtual communities of users exchanging data. In these domains, it is possible to define overlaying structures that we call “Preference Networks” that show self organized interest-based clusters. The relevance of this finding is augmented with the introduction of a proactive recommendation scheme that exploits this natural feature. The intuition behind this scheme is that a user would trust her network of “elective affinities” more than anonymous and generic suggestions made by impersonal entities.

Uncertainty Modeling of a Group Tourism Recommendation System Based on Pearson Similarity Criteria, Bayesian Network and Self-Organizing Map Clustering Algorithm
Group tourism is one of the most important tasks in tourist recommender systems. These systems, despite of the potential contradictions among the group's tastes, seek to provide joint suggestions to all members of the group, and propose recommendations that would allow the satisfaction of a group of users rather than individual user satisfaction. Another issue that has received less attention i...
متن کاملRecommendation system based on the clustering of frequent sets
Generating shopping recommendations has become a classical problem in knowledge engineering with extensive practical applications. In this article we propose a system for the generation of such recommendations based on considering both local and global influences. Key-Words: shopping recommendation, frequent sets, clustering, self-organizing maps
متن کاملToward Systemic MAS Development: Enforcing Decentralized Self-organization by Composition and Refinement of Archetype Dynamics
The utilization of self-organizing processes promises scalability, robustness and adaptivity in Multi-Agent Systems (MAS), solely based on decentralized coordination of individual actors. Bionic development approaches are being established, which reuse decentralized coordination mechanisms that are derived from natural self–organizing systems. In this paper, we address analysis activities in in...

With the development of the Internet, the problem of information overload is becoming increasing serious. People all have experienced the feeling of being overwhelmed by the number of new books, articles, and proceedings coming out each year. Many researchers pay more attention on building a proper tool which can help users obtain personalized resources. Personalized recommendation systems are ...
متن کاملDecentralized semantic service discovery based on homophily for self-adaptive service-oriented MAS
The aim of my PhD thesis is to propose a decentralized system for service management based on the social concept of homophily. The system provides self-organizing features, and it is established and maintained without supervision. Each agent manages autonomously events such as searching services, joining or leaving the system, which reduces the service management and the structure maintenance c...
