Wise design strategies for efficient ultraviolet (UV) hot exciton molecules are highly desired. In this work, inspired by the long-short axis skeleton strategy, theoretical perspective for the substituent effect of...

In this paper the satisfaction of users on information retrieval results was analyzed and the search result was modified and resorted, based on which the relevance ranking algorithm was proposed. The method calculated a value for every returned result and sorted the value in descending order. At last, the value was output and returned it to the users. The realization of relevance ranking improved the retrieval efficiency greatly and it made the returned results more consistent with the users' query intent.
