Searching for expertise in social networks

Jun Zhang, Mark S. Ackerman
2005 Proceedings of the 2005 international ACM SIGGROUP conference on Supporting group work - GROUP '05  
In this paper, we examine three families of searching strategies that we believe may be useful in expertise location. We do so through a simulation, based on the Enron email data set.  ...  People search for people with suitable expertise all of the time in their social networks -to answer questions or provide help. Recently, efforts have been made to augment this searching.  ...  Evaluation Criteria Compared to searching a file in peer-to-peer file networks or searching for a person in a small world experiment, searching for expertise in social networks is a far more complex process  ...

Searching social networks

Bin Yu, Munindar P. Singh
2003 Proceedings of the second international joint conference on Autonomous agents and multiagent systems - AAMAS '03  
This paper studies strategies using which agents may search dynamic social networks.  ...  Further, it presents a prototype system that assists users in finding other users in practical social networks.  ...  Thus the problem of searching a social network reduces to routing queries in a corresponding referral system. MINDS and ReferralWeb are two major approaches for referral systems.  ...

Locating Experts via Online Social Networks

K. Xu, J. Xie, V. O. K. Li
2010 2010 IEEE International Conference on Communications  
In this paper, from a networking point of view, we study the problem of locating experts for relevant information via online social networks.  ...  We model the action of forwarding a question with random walk, adjusted by a node's awareness of the potential expertise of his immediate neighbours.  ...  ACKNOWLEDGEMENT This research is supported in part by the University of Hong Kong Strategic Research Theme of Information Technology.  ...

Expertise Discovery in Decentralised Online Social Networks

Safina Showkat Ara, Subhasis Thakur, John G. Breslin
2017 Proceedings of the 2017 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining 2017 - ASONAM '17  
In this paper we propose to use crowd sourcing for information retrieval in a DSN. We analyze a popular information retrieval problem called expert search in a social network.  ...  In absence of a centralized entity with access to all social network data, information retrieval becomes dicult in DSNs.  ...  Distributed Social Network (DSN) can provide a potential mitigation of the security and privacy problems of OSNs.  ...

The Innochain Network - Introduction (The Innochain Network Journal #0)

Mathilde Marengo
2017 Zenodo  
This Journal introduces the Innochain network, its academic and industrial partners and teh 15 affiliated Early Stage Researcher Projects.  ...  For this reason, these methods search for a single solution that can address a steady design problem in the later phases of design.  ...  Rather than using a top down strategy, where the designer searches for the preferred solution manually and optimizing the selected solution in a later step, s/he becomes the builder of the process, investigating  ...

Recommendation Boosted Query Propagation in the Social Network [chapter]

Grzegorz Kukła, Przemysław Kazienko, Piotr Bródka, Tomasz Filipowski
2010 Lecture Notes in Computer Science  
In this paper we present a new system which uses this social network to improve the communication processes.  ...  It exploits the social network existing within the organization together with information about expertise of community members to recommend the best way to get the answer over the chains of acquaintances  ...  Dispersed search algorithm treats SN as a set of potential experts who anyone can ask a question.  ...

SIMULATING KNOWLEDGE DYNAMICS IN INNOVATION NETWORKS (SKIN)

PETRA AHRWEILER, ANDREAS PYKA, NIGEL GILBERT
2004 Industry and Labor Dynamics  
An agent-based simulation model representing a theory of the dynamic processes involved in innovation in modern knowledge-based industries is described.  ...  The interactions between the agents occur on two levels: through a market with firms supplying and consuming goods for a price, and through the exchange of knowledge.  ...  If there is a firm sufficiently attractive according to the chosen search strategy (i.e. with attractiveness above the 'attractiveness threshold'), it will stop its search and offer a partnership.  ...

Randy Gimblett, Robert Itami, Aaron Poe
2014 Networks in Society  
This provides the basis for developing a generic simulation platform called the Business Network Agent-Based Modelling System (BNAS).  ...  In order to develop appropriate researchbased management and policy advice we need a better understanding of how business relations and networks form and evolve.  ...  There are many examples of partner search and mating mechanisms in simulations, as it is one of the core mechanisms necessary to design a network simulation.  ...

Semantic social overlay networks

A. Loser, S. Staab, C. Tempich
2007 IEEE Journal on Selected Areas in Communications  
In this paper, we propose a new mechanism, INGA, which is based on the observation that query routing in social networks is made possible by locally available knowledge about the expertise of neighbors  ...  Peer selection for query routing is a core task in peer-to-peer networks. Unstructured peer-to-peer systems (like Gnutella) ignore this problem, leading to an abundance of network traffic.  ...  Rephrased in a peer-to-peer (P2P) terminology, peers may find relevant information in a real-world social network which is highly dynamic w.r.t. peer availability and expertise on topics using their local  ...

To explain the sources of heterogeneity and fragility in the financial sector, we develop a dynamic model of entry, exit, and firm quality in the market for issuance and trading of complex financial securities  ...  We find that increasing the quality of securities, which in the model increases the scope for investment in trading expertise, leads to markets that exhibit greater concentration, firm heterogeneity, fragility  ...  (2014) study adverse selection in financial markets using a search framework.  ...
