A Leader Decision Assistant Information System based on Content Recommendation and Cosine Similarity Algorithm

[Objective] In order to help the leaders to collect and find the information quickly and accurately, improving the efficiency and accuracy of the decision-making of leader of the government, the decision support system that meets the decision-making characteristics of the party and government agencies is studied. [Methods] We design a leadership decision support system which is based on the content recommendation and cosine similarity algorithm. The system includes decision information database, user decision feature database, decision information collection subsystem and decision information push subsystem. [Results] The system is applied in the government decision support system, which can push information according to the key words and the preference of the leader. The accuracy of the pushing results is high, which is consistent with the expectation of the leader. [Conclusion] The system has better accuracy and pertinence according to the user preferences and characteristics, which has opened up a new idea for the design and construction of the decision-making assistant system of the party and government agencies.
