Guanfeng Liu, Kai Zheng, Yan Wang, Mehmet A. Orgun, An Liu, Lei Zhao, Xiaofang Zhou
2015 2015 IEEE 31st International Conference on Data Engineering  
However, the existing GPM methods do not consider the multiple constraints on edges in GQ, which are commonly exist in various applications such as, crowdsourcing travel, social network based e-commerce  ...  Then, to address the efficiency issue in largescale MC-GPM, we propose a new concept called Strong Social Component (SSC), consisting of participants with strong social connections.  ...  Given a graph pattern query with multiple constraints, e.g., (B, D) of G Q4 in Fig. 2 , based on the social context index, we can quickly investigate if there exists an edge pattern matching in the data  ...

DISCOVERING AND MANAGING SOCIAL COMPOSITIONS IN COLLABORATIVE ENTERPRISE CROWDSOURCING SYSTEMS

FLORIAN SKOPIK, DANIEL SCHALL, SCHAHRAM DUSTDAR
2012 International Journal of Cooperative Information Systems  
In order to efficiently discover member compositions based on artifact dependencies, we introduce an indexing and discovery approach based on subgraph matching.  ...  Hence, technical dependencies of artifacts result in social dependencies of collaborating crowd members that create them.  ...  Trust in Social Networks. Social Trust 15,61-63 in service-oriented systems has become a very important research area.  ...

Modeling and Mining of Dynamic Trust in Complex Service-Oriented Systems [chapter]

Florian Skopik, Daniel Schall, Schahram Dustdar
2011 Socially Enhanced Services Computing  
We argue that trust between members is essential for successful collaborations. Unlike a security perspective, we focus on the notion of social trust in collaborative networks.  ...  We show an interpretative rule-based approach to enable humans and services to establish trust based on interactions and experiences, considering their context and subjective perceptions.  ...  upon a predefined rule base, and updating the trust graph (EMA with a ¼ 0:25).  ...

Interaction-Driven Self-adaptation of Service Ensembles [chapter]

Christoph Dorn, Schahram Dustdar
2010 Lecture Notes in Computer Science  
Subsequent reconfiguration and replacement of services enables the ensemble to mature in parallel with the evolution of its user community.  ...  The software services in such systems cannot adapt to user needs based on autonomous principles alone.  ...  Along with the capability model, we have introduced a constraint matching and selection algorithm in [22] .  ...

SocialScope: Enabling Information Discovery on Social Content Sites [article]

Sihem Amer-Yahia, Cong Yu
2009 arXiv   pre-print
These community standards enable the open access to users' social profiles and connections by individual content sites and are bringing content-oriented sites and social networking sites ever closer.  ...  Recently, many content sites have started encouraging their users to engage in social activities such as adding buddies on Yahoo! Travel and sharing articles with their friends on New York Times.  ...  Graph patterns make it possible to achieve these steps more concisely. Figure 2 depicts a graph pattern showing a 'match' link followed by a 'visit' link.  ...

A Connection-Centric Survey of Recommender Systems Research [article]

Saverio Perugini, Marcos Andre Goncalves, Edward A. Fox
2003 arXiv   pre-print
Finally, user modeling and the connection-centric viewpoint raise broadening and social issues--such as evaluation, targeting, and privacy and trust--which we also briefly address.  ...  We therefore take a connection-oriented viewpoint toward recommender systems research.  ...  Thus, one user may be matched against many topics and multiple users may be interested in the same topic. Users proceed to rate results.  ...
