Whole sentence generating method and device

Abstract

The invention discloses a method for generating a complete sentence. The method includes that segment the context on the both sides of candidate words; search each candidate word and the co-occurrence word frequency of the context in the word list; according to the co-occurrence word frequency, calculate the probability of compositing a complete sentence by each candidate word and the context, and select and output the candidate word with the highest probability to construct a complete sentence with the context. The invention also discloses a corresponding device, which comprises a query module, a first buffer area, a second buffer area, and a complete sentence output module; wherein, the first and the second buffer areas are used respectively to store the upper and the lower texts input by the current pinyin; the query module is used to search the word frequency of each candidate word and the co-occurrence word frequency of each candidate word and the context phrases; the complete sentence output module is used to calculate according to the condition probability of the co-occurrence of each candidate word and the context, and select the candidate word with the high condition probability to form and output the complete sentence with the context. The invention has a more high accuracy to output complete sentences.

Description

technical field [0001] The invention relates to Chinese character input technology, in particular to a method and device for generating a complete sentence. Background technique [0002] In the process of typing, it is often necessary to modify the input text, such as deleting individual words or sentences or inserting individual words and sentences, so that a new whole sentence needs to be generated according to the newly inserted words or words and sentences. Inserting a word or a sentence in the middle of a sentence in a traditional input method is no different from inputting in other occasions. The most commonly used method is the maximum probability method. The pinyin input method is taken as an example to describe in detail below. [0003] In the pinyin input method, one Chinese pinyin string can correspond to multiple candidate words. For example, the candidate words corresponding to the pinyin string of "dajia" may include: everyone, fighting, Dajia, cracking down...

Problems solved by technology

But using this method, only the word with the highest word frequency can be selected. If the first candidate word is incorrect, the user has to re-select each phrase, and the accuracy rate is not high.
