Query Answering via Decentralized Search [article]

Liang Ma
2020 arXiv   pre-print
However, there is still a lack of fundamental understanding of the efficiency of decentralized search in expert networks.  ...  query answering efficiency is sensitive to the underlying query routing mechanism being used.  ...  CONCLUSION We investigated the efficiency of local-information-based decentralized search for query answering in expert networks, focusing on quantifying the performance of decentralized 3 Note that  ...

Social Information Retrieval with Agents

Federico Bergenti, Agostino Poggi, Michele Tomaiuolo
2014 Workshop From Objects to Agents  
We argue that agent technology is central in supporting the decentralization of next generation online social networks and the synergistic pairing of agents and social networks is evident, if nothing else  ...  , because members of a social network interact as agents do in a multiagent system.  ...  The constructed network is then used to guide the search for people or documents in response to user queries.  ...

Data Sharing in P2P Systems [chapter]

Rabab Hayek, Guillaume Raschia, Patrick Valduriez, Noureddine Mouaddib
2009 Handbook of Peer-to-Peer Networking  
This last part shows the lack of querying techniques that allow for an approximate query answering.  ...  Complex query facilities are necessary for advanced applications which require a high level of search expressiveness.  ...  Partial Answering As seen before, a first repercussion of the scale of P2P systems on query processing is that all queries can partially search the network.  ...

A Social P2P Approach for Personal Knowledge Management in the Cloud [chapter]

Rebeca P. Díaz Redondo, Ana Fernández Vilas, Jose J. Pazos Arias, Sandra Servia Rodríguez
2012 Lecture Notes in Computer Science  
With his scenario in mind, this paper introduces a peer-to-peer solution to the problem of sharing personal knowledge for social search.  ...  We propose a routing mechanism in a peers' network, which uses both information about the social relation among peers and their personal knowledge.  ...  Answer propagation throughout the peers network.  ...

A Distributed Framework for Content Search Using Small World Communities

Seyyed-Mohammad Javadi-Moghaddam, Stefanos Kollias
2016 International Journal of Advanced Computer Science and Applications  
Evaluation of the framework proves that the small world character of the proposed structure provides queries with better route selection and searching efficiency.  ...  One of the important parameters in a distributed environment is system response time. This parameter specially plays an important role in search and retrieval.  ...  As was above mentioned, decentralization as well as efficiency are important and desired factors.  ...
