Detailed Description

In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:

if an input syllable string is received, at least two tone-form first syllables can be provided for a first syllable in the syllable string, then the first syllable in the first tone form is determined from the at least two tone-form first syllables, and when a candidate item is finally provided, only a Chinese character candidate item matched with the first syllable in the first tone form needs to be provided, and all Chinese character candidate items corresponding to the first syllables do not need to be provided, so that the technical effect of improving the Chinese character input efficiency is achieved;

In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.

In a first aspect, an embodiment of the present invention provides a method for inputting chinese characters, please refer to fig. 1, including:

step S101: receiving an input syllable string, and detecting a preset operation aiming at a first syllable in the syllable string;

step S102: providing the first syllables in the form of at least two tones in response to the preset operation;

step S103: determining the first syllable of the first tone form from the first syllables of the at least two tone forms based on a selection operation of a user;

step S104: providing a Chinese character candidate matching the first syllable of the first tone form.

For example, the scheme is applied to electronic equipment with a Chinese character input function, such as: a mobile phone, a tablet computer, a notebook computer, etc., embodiments of the present invention are not limited.

In step S101, a syllable refers to the pronunciation of a chinese character, and a syllable string may include a syllable, for example: gao, gan, etc., and may also contain multiple syllables, such as: gaojin, ganjin, etc., a string of syllables may contain partial syllables in addition to complete syllables, such as: gaoj, ganj, etc., and the practice of the invention is not limited.

In the implementation, the syllable string can be input through various keyboards, such as: firstly, inputting a syllable string through a full-key keyboard, wherein in this case, one key corresponds to one character in the syllable string, and as shown in fig. 2a, the key is a schematic diagram of the full-key keyboard; secondly, inputting syllable strings through a non-full-key keyboard, for example: the nine-grid keyboard, in this case, one key corresponds to a plurality of characters, as shown in fig. 2b, which is a schematic diagram of the nine-grid keyboard.

In the specific implementation process, the first syllable in the syllable string can be displayed in a plurality of different regions, and the preset operation can be an operation for the first syllable displayed in different regions, which is described below by exemplifying some cases, but is not limited to the following cases in the specific implementation process.

First, the detecting a preset operation for a first syllable of the syllable string when the syllable string is input through a full-key keyboard, includes: detecting the preset operation for the first syllable displayed on a syllable string display region.

For example, referring to fig. 2a, after the user inputs the syllable string through the full-key keyboard, the syllable string is displayed in the syllable string display area, the syllable string shown in fig. 2a includes the syllables "gan" and "jin", the user may generate the preset operation for the syllable "gan" if he/she wants to display at least two tone forms of the syllable "gan", the user may generate the preset operation for the syllable "jin" if he/she wants to display at least two tone forms of the syllable "jin", of course, in the specific implementation, the first determined syllable is different based on the difference of the syllables input by the user, and the embodiment of the present invention is not limited.

Second, the detecting a preset operation for a first syllable of the syllable string when the syllable string is input through a non-full-key keyboard includes: detecting the preset operation aiming at the first syllable displayed in a syllable string display area, wherein the current syllable corresponding to the input operation of the user is displayed in the syllable string display area.

For example, if a syllable string is input through the non-full-key keyboard, a first syllable is displayed in both the syllable string display region and the syllable candidate region, wherein a current syllable corresponding to the input operation of the user is displayed in the syllable string display region, and the current syllable includes, for example: a default syllable of a key combination corresponding to the input operation by the user, a syllable selected by the user from a plurality of syllables corresponding to the key combination corresponding to the input operation, and the like.

Taking the case of the maotai grid keyboard shown in fig. 2b as an example, assuming that the key corresponding to the input operation by the user is "426546" and the default syllable thereof is "ganjin", the syllable string "ganjin" is displayed in the syllable string display region, however, the key "426546" may correspond to other syllables, and other syllables may be displayed in the syllable alternative region, wherein other syllables of the partial key combination corresponding to the key "426546" may be displayed, and other syllables of all the key combinations corresponding to the key "426546" may be displayed, and as an example shown in fig. 2b, other syllables corresponding to the partial key combination "426" displayed include "gan", "gao", "hao", "han", and "near", and in addition, the syllable "hao" of the syllable candidate region may be selected by the user, and in this case, the syllable string "haojin" is displayed in the syllable string display region, of course, the syllable string display area and the syllable alternative area can also display other syllables, and the embodiment of the present invention is not listed in detail and is not limited.

Wherein, if the user desires to display at least two tone forms of the syllable "gan", a preset operation may be generated for the syllable "gan" displayed in the syllable string display region.

Third, the detecting a preset operation for a first syllable of the syllable string when the syllable string is input through a non-full-key keyboard includes: detecting the preset operation aiming at the first syllable displayed in a syllable alternative area, wherein a syllable combination of a key corresponding to the input operation of the user is displayed in the syllable alternative area.

For example, in the case of a non-full-key keyboard, the first syllable may be displayed in the syllable string display region or in the syllable candidate region, so that when the preset operation is performed for the first syllable, the preset operation may be performed for the first syllable displayed in the syllable string display region, or the preset operation may be performed for the first syllable displayed in the syllable candidate region.

Fourth, the detecting a preset operation for a first syllable of the syllable string when the syllable string is input through a non-full-key keyboard includes: determining a syllable combination of a key corresponding to the input operation of the user; selecting a first syllable from the syllable combination; detecting the preset operation for the selected first syllable.

Taking the syllable string shown in fig. 2b as an example, the syllable string "ganjin" displayed in the syllable string display region and the syllable string that the user may need to input is "haojin", in this case, the first syllable "hao" may be selected from the syllable combination based on the selection operation of the user, and then the syllable string "haojin" may be displayed in the syllable string display region, and then the preset operation of the user for the syllable "hao" displayed in the syllable string display region may be detected.

In step S102, the preset operation may be a plurality of preset operations, for example: firstly, aiming at the long pressing operation of the first syllable; click operation for the first syllable; and thirdly, generating preset gesture operation and the like aiming at the first syllable, wherein the preset gesture is as follows: move the first syllable upward, move the first syllable downward, contain pressure information, and the like.

In step S103, the at least two tone forms include, for example: at least two tone forms of first sound (yin Ping), second sound (yang Ping), third sound (rising) and fourth sound (de-voicing).

Assuming that the user inputs a syllable string through the full-key keyboard shown in fig. 2a and the first syllable is "gan", the first syllables of at least two tone forms as shown in fig. 3a may be provided; and if the first syllable is "jin", at least two tone forms of the first syllable shown in fig. 3b may be provided, and the at least two tone forms of the first syllable in fig. 3a and 3b are all displayed in the syllable string display region.

Assuming that the user inputs the syllable string through the non-full-key keyboard shown in fig. 2b and the first syllable is "gan", the first syllable of at least two tone forms as shown in fig. 3c may be provided, or the first syllable of at least two tone forms as shown in fig. 3d may be provided, the first syllable of at least two tone forms as shown in fig. 3c is displayed in the syllable string display area, and the first syllable of at least two tone forms as shown in fig. 3d is displayed in the syllable alternative area, of course, in the specific implementation process, the first syllable of at least two tone forms of other forms may also be provided, which is not illustrated in detail and is not limited in this embodiment of the present invention.

In the above scheme, the first syllables in at least two tone forms are displayed in the syllable string display region or the syllable alternative region, so that the display space of the electronic device is not required to be occupied additionally.

In step S104, if the chinese character candidates matching the first syllable are directly provided, all the chinese character candidates matching the first syllable need to be obtained first, and then provided to the user after being sorted according to word frequency, in this case, the user may want to input chinese characters that are sorted later, so the user needs to turn many pages to find the required chinese characters; if the Chinese character candidate item matched with the first syllable is directly provided, the Chinese character candidate item meeting the first tone form can be obtained from all the Chinese character candidate items matched with the first syllable, and then the Chinese character candidate items meeting the first tone form are sequenced.

When the user is required to select the first tone form from the at least two tone forms, the at least two tone forms and the first syllable are combined and provided for the user, rather than providing the at least two tone forms, so that the user can select the first tone form more conveniently, and the accuracy of the selected first tone form and the efficiency of selecting the first tone form are improved (since one syllable string may include a plurality of syllables, and in the case that a syllable is not provided, the user may need to correspond to which syllable the selected tone form corresponds, the speed may be affected, and there may be errors).

In the specific implementation, after the syllable string is input based on step S101, when the preset operation of the user is not detected, a candidate corresponding to the syllable string may also be provided, and in the specific implementation, the candidate corresponding to the syllable string may be provided in various ways, two of which are listed below for description, and of course, in the specific implementation, the following two cases are not limited.

Firstly, the ranking order of the candidate items corresponding to the syllable string is determined by the following method: determining tone pressing pressure parameters generated when the user inputs the syllable string; and determining the arrangement sequence of the corresponding candidate items of the syllable string based on the tone pressing force parameter.

For example, the pressing force parameter may be an average pressing force value of each character input, or may be a pressure vector, and the pressing force parameter may be an absolute value or a relative value, for example: first a standard pressure value is set, and then each tone form corresponds to a predetermined multiple of the standard pressure value, for example: the first sound is 0.5 times of the standard pressure value, the second sound is 0.9 times of the standard pressure value, the third sound is 1.2 times of the standard pressure value, and the fourth sound is 1.5 times of the standard pressure value.

Wherein, assuming that the user wants to input the Chinese character "surpass", the user inputs the syllable string "shengg", and the input method application program detects that the multiple of the pressure corresponding to each character input when the user inputs the syllable string relative to the standard pressure is respectively: 1.6,1.4,1.3, 1.4,1.7, then the average of these six values can be obtained as the pressing force parameter, that is: (1.6+1.4+1.3+1.3+1.4+1.7)/6 ═ 1.45; these six values may also be combined to form a pressure vector p ═ 1.6,1.4,1.3,1.3,1.4,1.7], which is the pressing force parameter.

Wherein, the determining the ranking order of the corresponding candidate items of the syllable string based on the tone pressing force parameter includes, for example: determining similarity values of the candidate items corresponding to the syllable strings and the tone pressing strength parameters based on the preset corresponding relation between the candidate items and the pressing strength parameters; determining the ranking value of each candidate item by the following formula: score is freq + S × d, where score represents the ranking value of the corresponding candidate item, freq represents the word frequency of the corresponding candidate item, N represents the weight value occupied by the word frequency, and S represents the similarity value; determining the ranking order based on the ranking values of the respective candidate items.

Taking the pressing strength parameter as the pressure vector p as an example, assuming that the syllable string "shengg" includes the following candidates "birth", "win", "cherry", "shanggong", the preset candidate and pressure vector p have the following correspondence relationship:

p [ "grown" ], [0.5,0.5,0.5,0.5, 1.5 ];

p [ "wins" ], [1.5,1.5,1.5,1.5,1.5,1.5 ];

p [ "cherry tomato" ], [1.5,1.5,1.5,1.5, 1.2 ];

p [ "upprocessed" ], [0.5,0.5,0.5,0.5,0.5,0.5 ];

when calculating the similarity value between the pressure vector of the syllable string and each candidate, the similarity value can be calculated in various ways, for example: calculating similarity values between the pressure vectors of the syllable strings and the pressure vectors of the candidate items directly through a similarity value calculation formula, wherein the similarity value calculation formula is as follows: cosine similarity calculation formula, pearson correlation coefficient calculation formula, and the like; calculating a distance value between the pressure vector of the syllable string and the pressure vector of each candidate by a distance calculation formula, and then obtaining a similarity value by taking the reciprocal of the distance value, wherein the distance calculation formula is as follows: a street city distance calculation formula, a euclidean distance calculation formula, a minkowski calculation formula, and the like.

Taking the example of calculating the similarity value between the pressure vector of the syllable string and the pressure vector of each candidate item through the city distance calculation formula, the distance value between the pressure vector of the syllable string and the pressure vector of each candidate item can be calculated through the city distance calculation formula, and then the distance value is inverted to obtain the similarity value.

Wherein d [ "fresh" ] ═

(|1.6-0.5|+|1.4-0.5|+|1.3-0.5|+|1.3-0.5|+|1.4-0.5|+|1.7-1.5|)/6＝0.78；

The same principle is adopted, and d [ "surpasses" ] ═ 0.15; d [ "cherry tomato" ] ═ 0.2; d [ "ascending official ] -1.12

The similarity value S [ "born" ]of1/0.78, S [ "wins" ]of1/0.15, S [ "cherry tomato" ]of1/0.2, S [ "rose" ]of1/1.12 can be calculated.

In the formula score + freq + N S, N may be set according to actual requirements, and its value is, for example: 10. 20, etc., assuming N equals 10.

The input method application program can obtain the word frequency of each candidate word by using 'shengg' query, and assume that the query obtains the following corresponding relation between the candidate word and the word frequency:

{ "raw over": 1000, "outperforms": 950, "cherry tomato": 770 … "officer: 450 };

the following rank values may be calculated based on the formula score + freq + N S: score [ "born" ] — 1013; score [ winning ] 1016; d [ "cherry tomato" ], 820; d [ "ascending official ] ═ 459

After determining the ranking value of each candidate, a ranking order may be determined based on the ranking values of each candidate, for example: and providing the various candidates to the user from high to low according to the ranking value.

Secondly, determining the arrangement order of the candidate items corresponding to the syllable string by the following method: determining the word frequency of each candidate corresponding to the syllable string, and determining the ranking order according to the word frequency of each candidate, for example: arranged from high to low in terms of word frequency.
