Detailed Description
In the technical scheme provided by the embodiment of the application, the input cost of the input word is obtained, and optimization is performed according to the input cost of the input word when the user word bank is optimized, so that the word with higher input cost is prevented from being preferentially deleted from the user word bank, the technical problem that the input efficiency is reduced when the user word bank is optimized in the prior art is solved, and the input efficiency of a user is improved.
The main implementation principle, the specific implementation mode and the corresponding beneficial effects of the technical scheme of the embodiment of the present application are explained in detail with reference to the accompanying drawings.
Example one
Referring to fig. 1, a method for optimizing a user lexicon provided in an embodiment of the present application includes:
s101: obtaining an input cost of an input word, wherein the input cost comprises an input character string length of the input word and/or an on-screen cost of the input word;
s102: and optimizing the number of the input words in the user word bank according to the input cost of the input words.
In a specific implementation process, the user lexicon optimization method provided in the embodiment of the present application is applied to an electronic device at a client, and when a user uses the electronic device at the client to perform character input, S101 is executed to obtain an input cost of an input word (a word input on a screen). Wherein the input cost comprises the input character string length of the input word and/or the on-screen cost of the input word.
The input character string length refers to the length of a character string directly input by a user, for example, the user inputs 'nihao' through an input method, and selects a candidate item 'hello' displayed correspondingly through conversion to be displayed on a screen, at the moment, the 'hello' is an input word, and the length 5 of the character string of the 'nihao' is the input character string length of the input word 'hello'.
The screen-on cost is used for representing the degree of convenience of operation when the user screens the candidate words, if the candidate words to be screened are located at the first candidate position of the first screen, the screen can be conveniently screened by directly clicking the space key, the convenience degree is the highest, the screen-on cost is limited by factors such as user sight lines, the more the candidate position is backward, the lower the convenience degree is, and the lower the convenience degree is when the page is turned or the words are manually grouped. Specifically, C is used for representing the cost of the screen, when a candidate word on the first screen is displayed, C is a candidate position, if the page turning C is a constant, pagenum + candidate position, pagenum represents a candidate page turned by the obtained candidate word, and when the page turning pagenum is not displayed on the first screen, the page turning pagenum is 0; if the words are manually organized, a penalty value is additionally added, so that the on-screen cost can be obtained through the following formula:
C＝a1*pagenum+x+a2
wherein C represents the cost of the screen-up, a1Representing a constant, pagenum representing a candidate page over which the input word is obtained, x representing a candidate position of the input word on a candidate interface, a2Added value of manual word forming for user, when the input word is not obtained by manual word forming for user2Is 0, a when the input word is obtained by manual word formation by the user2Is a non-zero positive number. The embodiment of the present application does not limit a1And a2The specific value of (3) can be 5, 10, 20 and the like.
For example: the user inputs ' nihao ', selects ' you ' with the candidate position of 4 on the first page of the candidate, then is in a half-selection state, then turns over 1 page to select ' you ' on the screen ' with the candidate position of 2, and assumes that a1And a2All the values of (1) are 10, and the input cost C of the input word "you hao" is 4+ (10 × 1+2) + 10.
When the input cost only includes the screen cost or the input character string length, the screen cost or the input character string length is directly used as the input cost. When the input cost comprises the screen-on cost and the input character string length, fitting the screen-on cost C and the input character string length l into the input cost by using two factors, and specifically obtaining the input cost according to the following formula:
Sc＝b1*c+b2*l
where Sc represents the input cost, l represents the input string length, b1、b2Represents a constant, b1+b2＝1.0。
After the input word and the input cost of the user are obtained, the input word and the input cost of the input word are written into a user word bank, and if the word is already in the user word bank, the maximum value of the input word and the input cost is taken. And optimizing the user word bank when the number of the user word banks reaches an upper limit, or periodically optimizing the user word bank every week, every month, every quarter and the like.
And S102 is executed, and the number of the input words in the user word library is optimized according to the input cost of the input words. Specifically, n input words with the lowest input cost may be preferentially deleted according to the input cost, where n is a positive integer. Because the input words with low input cost are deleted, the subsequent input does not influence the input efficiency.
For example: if the words on the screen in the user word stock have two words: "hello" (the first word located at the first screen, the input cost is 1, and the input character string length l is 5), "hello nothing" (the input character string is "nhaogawug", the input character string length l is 10, "hello" at the candidate position 3 is selected on the first page of the candidate page, "sono" at the candidate position 1 is selected by turning 1 page again, C is 3+10 + 1+10, and "b" is selected according to the formula Sc1*c+b2L (assume b)1、b2Both 0.5) and the input costs are respectively 3 and 16.5, so that the two words are eliminated according to the input costs, and the word "hello" is preferentially eliminated because the upper shielding cost is greater than the word "hello irrelevant".
Further, when the number of input words in the user word bank is optimized according to the input cost of the user, the latest screen-up time and screen-up times of the input words can be obtained, the comprehensive score of the input words is calculated according to the input cost, the latest screen-up time and the screen-up times, and n input words with the lowest comprehensive score in the user word bank are deleted. Specifically, the comprehensive score Co of the input word may be obtained according to the following formula:
Co＝c1*log(t/Tmax)+c2*log(f/Fmax)+c3*log((Sc)/Scmax)
wherein t represents the latest screen-up time of the input word, Tmax represents the latest screen-up time in the user lexicon, f represents the screen-up times of the input word, Fmax represents the maximum screen-up times in the user lexicon, Sc represents the input cost, Scmax represents the maximum input cost in the user lexicon, c1、c2、c3Represents a constant value, c1+c2+c3＝1.0。
In the technical scheme, a new user word stock slimming strategy is provided, and the user word stock is optimized according to the input cost of the input words, so that the input words with higher input cost are prevented from being deleted preferentially, the technical problem that the input efficiency is reduced during the optimization of the user word stock in the prior art is solved, and the input efficiency of characters is improved.
Furthermore, the input cost is added into a slimming strategy comprising the screen-up times and the screen-up time, the comprehensive score of the input word is obtained through fitting calculation of the input cost, the screen-up times and the screen-up time, the user lexicon is optimized according to the comprehensive score, and accuracy of optimization of the user lexicon is improved.
Example two
Referring to fig. 2, a method for optimizing a user lexicon provided in an embodiment of the present application includes:
s201: obtaining an ignoring factor of the input word, wherein the ignoring factor comprises the latest ignoring time, the ignoring time and/or the ignoring frequency of the input word which is displayed and not displayed on a screen;
s202: and optimizing the number of the input words in the user word bank according to the neglecting factor of the input words.
Similarly, the user lexicon optimization method provided by the embodiment of the application is applied to the electronic equipment at the user end. When inputting characters through the electronic device at the user end, S201 is executed to obtain the ignoring factor of the input word (word input on the screen). The ignoring factor is a parameter of words in the user word stock which are displayed but not on the screen, and is used for representing the possibility of the input words being ignored, including the latest ignoring time and/or the ignoring times and/or the ignoring frequency of the words which are displayed and not on the screen.
Specifically, in the user input process, when some input words in the corresponding user word bank are displayed but not displayed on the screen, that is, are ignored, the currently ignored time field is obtained, the latest neglected time of the input words is updated to the current time field, and the neglected time is not modified for candidate words not in the user word bank. Similarly, the input times and the neglect frequency of the input words are updated with each input action of the user.
S202, optimizing the number of input words in the user word bank according to the neglect factors of the input words, specifically, calculating the neglect scores of the input words according to the neglect factors of the input words, and optimizing the number of the input words in the user word bank according to the neglect scores.
The neglect score is represented by y (h), y (h) is (Hmax-h)/Hmax, h represents the neglect factor of the input word, Hmax represents the largest neglect factor in the user lexicon, and the smaller the neglect score is, the higher the possibility that the input word is ignored is, and the smaller the neglect score is. When the forgetting factor h is the latest forgetting time, Hmax represents the maximum latest forgetting time in the user lexicon (i.e., the forgetting time field of the input word that was most recently ignored among all the input words). In performing the skip score calculation, the most recent skip time is added to the calculation in the form of a numerical value, such as time 2016.8.25, which is a binary number when stored and used directly when calculated. When the forgetting factor h is the number of times of forgetting or the frequency of forgetting, Hmax represents the maximum number of times of forgetting or the highest frequency of forgetting in the user lexicon. When the neglect is two or three parameters of the neglect times, the neglect frequency and the neglect time, the parameter neglect scores respectively calculated by the parameters can be weighted to obtain the final neglect score.
It should be noted that the ignore score may also be calculated by using y (h) ═ h/Hmax, where a larger ignore score indicates a higher probability that the input word is ignored, and vice versa. In the following, the calculation of the comprehensive score of the input word is exemplified by (Hmax-h)/Hmax, and when the neglected score is calculated by (y), (h) -h/Hmax, it is only necessary to multiply the neglected score by-1, because the contribution of the neglected score to the input word at this time is negative.
When the number of input words in the user word bank is optimized according to the neglected scores, n input words with the lowest neglected scores can be deleted, wherein n is a positive integer. For example: the user inputs 'huijia', the user can go to the screen and get home certainly, the neglecting time is 0, the neglecting score is 1, but the condition of inputting 'huijia' is less, so the screen-going times of 'home' are less; if the user inputs feiji, the user may go to "airplane", "fat chicken", "feiji", etc., wherein the neglect time of "fat chicken" is 0810, and the neglect score is 0.02, and now the user lexicon is optimized according to the neglect factor, and the "fat chicken" is preferentially deleted because the neglect score is low and is more likely to be neglected.
Certainly, when the number of input words in the user word bank is optimized, the latest screen-on time and screen-on times of the input words can be obtained; calculating to obtain a comprehensive score of the input word according to the latest screen-on time, the screen-on times and the neglecting factor; and deleting the n input words with the lowest comprehensive scores in the user word bank.
Specifically, when the comprehensive score of the input word is obtained by calculation according to the latest screen-on time, the screen-on times and the ignoring factor of the input word, the comprehensive score Co can be obtained according to the following formula:
Co＝c1*log(t/Tmax)+c2*log(f/Fmax)+c3*log((Hmax-h)/Hmax)
wherein t represents the latest screen-up time of the input word, Tmax represents the latest screen-up time in the user lexicon, f represents the screen-up times of the input word, Fmax represents the maximum screen-up times in the user lexicon, h represents the ignoring factor, Hmax represents the maximum latest ignoring factor in the user lexicon, c1、c2、c3Represents a constant value, c1+c2+c3＝1.0。
In the technical scheme, a new user word stock slimming strategy is provided, the user word stock is optimized according to the neglect factor of the input word, the input word which is frequently ignored or is ignored recently is preferentially deleted, the technical problem that the input efficiency is reduced during the optimization of the user word stock in the prior art is solved, and the input efficiency of characters is improved.
Furthermore, the neglect factor is added into the slimming strategy comprising the screen-up times and the screen-up time, the comprehensive score of the input word is obtained through fitting calculation of the neglect factor, the screen-up times and the screen-up time, the user lexicon is optimized according to the comprehensive score, and accuracy of optimization of the user lexicon is improved.

wherein Sc represents the input cost, Scmax represents the maximum input cost in the user lexicon, and d1、d2Represents a constant, d1+d2H denotes the forgetting factor, and Hmax denotes the largest forgetting factor in the user lexicon. When the forgetting factor h is the latest forgetting time, Hmax represents the maximum latest forgetting time in the user lexicon (i.e., the forgetting time field of the input word that was most recently ignored among all the input words).
