1. A text inputting method, comprising: obtaining a user input; generating a candidate sentence list according to the user input; for each candidate sentence in the candidate sentence list, respectively calculating a standard conditional probability of each word in the candidate sentence according to a universal language model; respectively calculating a cache conditional probability of each word in the candidate sentence according to a preconfigured modeling policy, the user input and a precached user input; calculating a mixed conditional probability of each word according to the standard conditional probability and the cache conditional probability; obtaining an on-screen probability of the candidate sentence according to the mixed conditional probability; sorting candidate sentences in the candidate sentence list according to their on-screen probabilities; and outputting the sorted candidate sentence list; wherein: the cache conditional probability of each word in the candidate sentence is positively related to a time function value of the word, and the time function value is related to a time when the word enters a cache area used for the pre-cached user input; wherein the time function value is a result obtained by dividing a preconfigured constant by a time interval between an ith word enters the cache area and a word currently inputted by the user.
