Embodiment

[0040] The optimal keyboard layout of Jiugongge based on statistical natural language analysis, combined with the flow chart, includes the following steps:

[0041]Step 1: Chinese corpus research. By collecting different texts to conduct statistics on the Chinese corpus, it provides strong data support for the research on the optimal keyboard layout of Jiugongge. The Chinese corpus collected this time has a total of 857,276 words. After word frequency statistics, there are finally 42,535 different words. On the basis of considering word frequency, the average number of words per word is 1.582, and the text fragments processed by statistical natural language such as Figure 8 shown;

[0042] Step 2: Average keystrokes study. For a given keyboard layout scenario, the study calculates the average number of keystrokes;

[0043] Step 3: Research on the optimal keyboard layout scheme. Using the simulated annealing algorithm and iterating 1,000,000 times, the optimal keyboard lay...

Abstract

According to the invention, the optimal layout scheme of the Sudoku keyboard is obtained, the input efficiency of the Sudoku keyboard is obviously improved compared with that of sequential layout, and early-stage preparation work of cleaning a corpus through python programming, counting word frequency, calculating the average keystroke frequency of each layout and the like is mainly carried out; and 26 letters to 8 numeric keys are redistributed by taking the average keystroke frequency as a target function, and thus performing repetition judgment by adopting a Hash algorithm and performing iteration by adopting a simulated annealing algorithm to obtain a Sudoku keyboard layout with the least average keystroke frequency. The traditional Sudoku keyboard layout is changed, the problem that the traditional Sudoku does not conform to the Chinese input characteristics is solved, and the Chinese input speed of the Sudoku input method is increased.

Description

technical field [0001] The invention belongs to the field of optimizing keyboard layout, and specifically relates to statistical natural language processing, annealing algorithm, hash mapping and the like. Background technique [0002] Existing mobile phone Chinese text input method is based on Pinyin input method, and keyboard mainly adopts two kinds of Jiugongge keyboard and 26-key full keyboard. Jiugongge input method usually puts 26 letters in order on the 8 number keys 2-8, each key has 3-4 letters, and number keys 0 and 1 are used for other purposes. Due to the limitation of the screen size of the mobile phone, the usage rate of the 26-key full keyboard is not as high as that of the Jiugongge keyboard. Taking the Apple IOS input method as an example, it is not very friendly to Chinese input. After improvement, the Jiugongge input method is adopted. [0003] For historical reasons, the 26 letters of the PC keyboard are not in order. The 26-key full keyboard is laid o...
