Actors-media-qualities: a Generic Model for Information Retrieval in Virtual Communities

Gregor Heinrich
2010 International Conference on Innovations for Community Services  
It argues that alarge part of the information -and actually knowledge -present in virtual communities can be identified by agraph structure that consists of three node types -actors, media and qualities  ...  Based on these relations, information retrievaland other inference mechanisms can be mapped into the model. 1I ntroduction Virtual communities have become am ajor factor for the design of information systems  ...  This way, agreat part of the added value can be captured that is ascribed to community-based approaches compared to purely content-based ones, as suggested by the literature (see, e.g., [Wen98, HWW03]  ...

Correction to 'Comparison of social structures within cities of very different sizes': Table 1

P. Grindrod, T. Lee
2016 Royal Society Open Science  
For example, we find the social network of Manchester is very similar to the social network of a virtual city of the same size, where the virtual city is composed of communities from the Bristol network  ...  We show that in many cases one city can be thought of as an amalgamation of communities from another city.  ...  On top of the ensemble envelope of Q-values obtained for all of the virtual cities we show the other observed cities.  ...
