This software implements an agent-based framework that aggregates social network-level individual interactions to guide the construction of a successful decision support system (DSS) for WOM. The framework also has a data-driven iterative modeling approach to increase validity through automated calibration by metaheuristics. The framework is applied to run targeting and rewarding programs for a freemium social app where premium users discuss the product with their social network and promote the viral adoption.
The purpose of this model is to better understand the dynamics of premium and
paid content adoption in apps such as online game subscriptions. The goal of is to be used by marketers and decision makers to understand the social effects in these online purchases, and to test rewarding, incentives, and targeting policies to expand the number of premium users. This model will help us to better understand the dynamics of the social network of the app users.
There are local and potentially complex interactions between customers in WOM programs. For instance, customers can be influenced by their friends, and some of those friends may have a different amount of influence on them than other friends. This is easily captured in an ABM since each user can be modeled with their own social network connection and the weights on those connections.
WOM customers are very heterogeneous. They have both their own social networks that are unique to them, and potentially their own adoption process as well. The agent users or customers could have different seasonality patterns, different number of friends in her/his local social network, and different premium app subscription status.

Building Agent-Based Decision Support Systems for Word-Of-Mouth Programs. A Freemium Application (Journal of Marketing Research)
config folder: contains text files with extension .properties. These files have the parameters for running different scenarios and must be specified when calling the command-line software.
data folder: contains a couple of historical premium adoptions (synthetically modified from the original ones due to confidentiality issues). These files are CSV files and each value represents the new premium accounts created each day. In the sample folder we can find two of them, one with 60 days and another file with 31 days of premium conversions.
networks folder: we can find in this folder the social network file with the same distribution degree as in the real app. This file (dgs extension) is loaded by the application and the agents of the simulation are placed in its nodes at random. For each Monte Carlo run, agents are randomly shuffled to be placed in different nodes of the generated social network.
Apart from the above-mentioned contents, a JAR file is also included. This is the runnable file of the sofware. A Java Virtual Machine (>= 1.7) is needed to run the software.
Syntaxis to run the sofware is: “java -jar Agent-Based_Mk_DSS.jar + arguments”
Depending on the marketing scenario to run, arguments are the following:
java -jar Agent-Based_Mk_DSS.jar -noHist -configFile ./config/BassModel_EmpiricalSN_20000agents.properties -seed 1 -runs 15 -until 300
java -jar Agent-Based_Mk_DSS.jar -hist -configFile ./config/BassModel_EmpiricalSN_20000agents.properties -seed 1 -runs 15 -historicalFile ./data/premiums_31days_tst.csv
