Systems and methods for updating sequence of services
摘要
說明書
In some embodiments, the characteristic value may include a DCG (Discounted Cumulative Gain) value associated with a sequence of the plurality of services. The DCG value may indicate a quality of the sequence of the services. When sorting multiple elements, it may be desired that the significant elements should have higher ranks or prominent positions while the insignificant elements should have lower ranks. A larger DCG value of a sequence may indicate that more significant elements have higher ranks in the sequence (e.g., at the top). A smaller DCG value of a sequence may indicate that the one or more significant elements are assigned lower ranks in the sequence (e.g., at the bottom). The ratio between a characteristic value for the current sequence of the plurality of services and the characteristic value for the optimized sequence of the plurality of services may include an NDCG (Normalized Discounted Cumulative Gain) value. An optimized sequence may assign a most significant element the highest position (i.e., No. 1), then the second-most significant element the second-highest position (i.e., No. 2), etc. The NDCG value for the current sequence may vary from 0.0 to 1.0, with 1.0 indicating that the current sequence is exactly the optimized sequence.
In some embodiments, the user interface of the application may display a part of the plurality of services in an active window or interface. The user interface may display the other part of the plurality of services in a background window or interface.
