This is the code and data set for our AI 2016 paper. We used the same data set first presented in 
ECAI 2016 paper. We again include the data set here for convenience.
In this version, we introduced a simplified DIEL variant that does not use the student's t-distribution parameter. 
This DIEL version supercedes the DIEL presented in our earlier ECAI 2016 paper and is the up-to-date version of DIEL.  
The data set is in the Referral folder. 
Each .mat file decribes a referral networks of 100 experts and 10 topics. 
When you run the code in MATLAB, the results will be stored in the ReferralResults folder. 
The code is compatible with Windows 10 environment running MATLAB 2016b and versions beyond MATLAB 2016b.
