The article describes the new approach for quality improvement of automated dialogue systems for customer support service. Analysis produced in the paper demonstrates the dependency of the quality of the retrievalbased dialogue system quality on the choice of negative responses. The proposed approach implies choosing the negative samples according to the distribution of responses in the train set. In this implementation the negative samples are randomly chosen from the original response distribution and from the "artificial" distribution of negative responses, such as uniform distribution or the distribution obtained by transformation of the original one. The results obtained for the implemented systems and reported in this paper confirm the significant improvement of automated dialogue systems quality in case of using the negative responses from transformed distribution.Index Terms-Dialogue systems, Negative sampling, Dual Encoder, Retrieval-based dialogue systems.

For example, "the first item on the agenda of the first meeting of the National Security Council under President Reagan was international terrorism…. Secretary of State Alexander Haig announced … that 'international terrorism will take the place of human rights' as the number one priority of the Reagan administration. A decade later George Bush … proclaimed in his Inaugural Address that terrorism and drugs would be the two primary targets of his administration."
