I am interested in researching the predictive power of combining social network analytics (eigenvector & betweenness centralities, community detection, collaborative filtering, etc.) with traditional data mining techniques (random forest, K-NN, principal component analysis, etc.)
I have run into problems finding open source data sets that contain both relationship data for the SNA as well as attribute data for the traditional algorithms, and finally some attribute of interest worth modelling (accepted offer, $ spent, etc.)
Could anyone offer suggestions?
