Summary of experimental conclusion.

Number	Conclusion	Supporting experiments
	The three states in the network will stabilize to a fixed constant over time	Experiment 1
	The DAS optimal control strategy outperforms any uniform control strategy and can greatly improve the expected profit	Experiments 2 and 3
	Reversing negative reviews is more helpful in improving expected profits than improve silent evaluation	Experiment 2
	The probability of being converted to is positively correlated with expected profits	Experiments 4 and 6
	The probability of being converted to is negatively correlated with expected profits	Experiments 4 and 6
	The probability of positive evaluation is positively correlated with expected profits	Experiments 5 and 7
	The probability of negative evaluation is positively correlated with expected profits	Experiments 5 and 7
	Probability influenced by positive WOM is positively correlated with expected profits	Experiments 4 and 6
	Probability influenced by negative WOM is negatively correlated with expected profits	Experiments 4 and 6
	When the probability of positive (negative) WOM is fixed and small, the probability of silent evaluation has a weak positive (negative) correlation with purchase intention	Experiment 5
	When the probability of positive (negative) WOM is fixed and large, the probability of silent evaluation has a strong positive (negative) correlation with purchase intention	Experiment 5
