This is the code and data set for our ISMIS 2018 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 market-aware Proactive-DIEL where agents advertise skills that give them 
advantage over their peers. The new algorithm has two configurable parameters C1, and C2. 
C1 is set to 50 and C2 is set to 1.   
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.
