Description

Input method error correction method and device
Technical Field
The invention relates to the technical field of input methods, in particular to an input method error correction method and device.
Background
The current input method error correction function is mainly based on the position error correction rule of adjacent key positions, and the error correction rule replaces corresponding code characters in a code character string input by a user with code characters corresponding to the adjacent key positions, then correspondingly converts the replaced code character string, and returns the converted code character string to a candidate entry corresponding to the code character string corrected by the user. For example: the user intends to input 'eat', but can not accurately locate the corresponding key position when inputting the coded character 'n', mistakenly hit the'm' key position beside the 'n' key position, the input coded character string becomes 'chifam', when the input method is used for error correction, the coded character'm' is replaced by the coded character 'n' corresponding to the adjacent key position 'n' of the'm' key position by analyzing the input coded character string, the input coded character string is corrected to 'chifam', and then the corresponding candidate vocabulary entry 'eat' is returned.
However, there are many uncertain factors in the user's input, and the erroneous input of the code character is usually not caused by the erroneous pressing of the adjacent key, but is also caused by the unintentional touching of other non-adjacent keys. If the user inputs the code character string and performs the screen-on operation, when the finger moves from the last code character input key position to the corresponding candidate entry in the candidate frame, the user is easy to miss one or more other keys in the middle; or, when the user finishes the screen-on operation and continues inputting, the finger moves from the candidate frame to the first coded character key position, and other key positions are easily erased by mistake; or, in the process of inputting the code character string, the user can easily miss other key positions due to factors such as environment, jitter, operation interface size and the like. Obviously, the above-listed cases of mistakenly inputting coded characters do not pertain to the case of mistakenly pressing an adjacent key.
Therefore, the existing input method error correction scheme is generally only suitable for the problem of erroneous input caused by adjacent key positions, but in the practical application process, users can inevitably cause erroneous input caused by touching non-adjacent key positions, but the existing input method error correction scheme cannot effectively correct the code character strings erroneously input by erroneously pressing the non-adjacent key positions. Because the existing input method error correction scheme cannot effectively correct the mistakenly input coded character string by mistakenly pressing a non-adjacent key, the mistakenly input coded character string of the user cannot be converted into the coded character string which is intended to be input by the user correspondingly, and finally, the candidate entry which the user wants cannot be returned, namely, the reliability of the candidate entry pushed to the user is poor.
Therefore, it is a technical problem to be solved by those skilled in the art to provide an input method error correction scheme capable of performing error correction on a code string generated by various error input operations of a user, so as to obtain a code string intended to be input by the user, and further improve reliability of a candidate entry pushed to the user.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart illustrating steps of an input method error correction method according to a first embodiment of the present invention is shown.
The input method error correction method of the embodiment of the invention comprises the following steps:
step S102: and receiving an input first code character string, and marking code characters of which the touch control strength is out of the currently set touch control strength range when the input code characters in the first code character string are input.
The marking of the code characters in the first code string may be performed in any suitable manner. For example: after the input of the whole first code character string is completed, the code characters of which the input touch strength is out of the currently set touch strength range can be marked in a unified manner. Or judging the touch strength of each code character when inputting the code character, and then determining whether to mark the code character according to the judgment result.
Step S104: and deleting the marked code characters in the first code character string and generating a second code character string.
In this step, the first code string is corrected according to the predetermined touch force range to generate a second code string.
Step S106: and determining a candidate entry corresponding to the first coding character string.
Step S108: and determining a candidate entry corresponding to the second encoding character string.
It should be noted that, for the operation of determining the candidate entry corresponding to the code character string, reference may be made to related technologies, which is not specifically limited in the embodiment of the present invention.
Step S108 is not limited to being performed after step S106, and may be performed at any time after step S102 and before step S110.
Step S110: and sequencing and displaying the candidate entries according to a set rule.
The candidate entries comprise a candidate entry corresponding to the first encoding character string and a candidate entry corresponding to the second encoding character string.
When the candidate entries are sorted, reference may be made to a technology for sorting and displaying the candidate entries, which is not specifically limited in the embodiment of the present invention. For example: the ranking is performed based on the type, word frequency, context, time, location, application environment, group to which the user belongs, and the like of the candidate entries.
The input method error correction scheme provided by the embodiment of the invention judges whether the code character is input by the user by the touch control strength when the code character is input based on the principle that the touch control strength when the code character is input by mistake is different from that when the code character is input normally. Because whether the code character is wrongly input is judged based on the touch strength, the method is not only suitable for judging the wrongly input caused by the adjacent key position, but also suitable for judging the wrongly input caused by the non-adjacent key position, and therefore the error correction can be effectively carried out on the wrongly input code character string which is not adjacent to the key position. Moreover, in the input method error correction method provided by the embodiment of the present invention, the candidate entries corresponding to the first encoded character string and the second encoded character string are sorted and displayed according to the set rule. Thus, the entry required by the user can be ensured in the candidate entry, and the reliability of the candidate entry pushed to the user is ensured.
Example two
Referring to fig. 2, a flowchart illustrating steps of an input method error correction method according to a second embodiment of the present invention is shown.
The input method error correction method of the embodiment of the invention comprises the following steps:
step S202: and respectively receiving an upper limit value and a lower limit value of the currently set touch force range.
The input method error correction method provided by the embodiment of the invention is suitable for the input method client, and the input method client comprises but is not limited to: and the input method client side comprises an input method client side such as a mobile phone, a tablet, a computer and an intelligent terminal.
In the embodiment of the present invention, the currently set touch strength range includes an upper limit value and a lower limit value, and the description is given by taking an example in which a user directly inputs the currently set touch strength range value. However, in the specific implementation process, the currently set touch force range is not limited to the obtained mode, and the currently set touch force range may also be obtained through the following two preferred modes:
the first preferred mode is to receive touch control operations of set times input by a user, determine touch control strength corresponding to each touch control operation, and determine a currently set touch control strength range according to each touch control strength.
One preferable way to determine the currently set touch strength range according to each touch strength is as follows: generating a distribution graph, such as a normal distribution graph, according to each touch strength, discarding the touch strengths at two ends of the normal distribution graph, selecting only the touch strength in a certain data area in the middle of the normal distribution graph, and then determining the currently set touch strength range according to the touch strength in the data area. In the preferred mode of determining the currently set touch strength range, the incredible touch strength is abandoned, so that the obtained touch strength range has higher reliability.
It should be noted that, when determining the Touch strength corresponding to each Touch operation, the determination may be performed by using a 3D-Touch related pressure sensing and control technology. Of course, the touch strength corresponding to each touch operation can also be determined by arranging a touch strength sensing module under the display screen.
In the second preferred mode, the currently set touch strength range corresponding to the latest input encoded character string is adjusted based on the currently set touch strength range corresponding to the latest input encoded character string before and when the encoded character string is input this time, the latest input encoded character string error correction result, and the result of the entry on the screen of the user, and the adjusted touch strength range is used as the currently set touch strength range in step 202.
The specific scheme for adjusting the currently set touch control force range corresponding to the latest input of the code character string is as follows:
and when the marked code character does not exist in the code character string input for the last time and the candidate entry corresponding to the code character string input by the user is displayed on the screen, keeping the currently set touch control force range unchanged. That is, the currently set touch strength range when the user performs the current input in step S202 is the same as the currently set touch strength range corresponding to the latest input.
And when the marked code characters exist in the code character string input for the last time and the candidate entry corresponding to the code character string after error correction is displayed on the screen of the user, keeping the currently set touch control force range unchanged. That is, the currently set touch strength range when the user performs the current input in step S202 is the same as the currently set touch strength range corresponding to the latest input.
When the marked code character exists in the code character string input last time and the candidate entry corresponding to the code character string after the user does not perform screen error correction, the currently set touch strength range is adjusted according to the touch strength range increase factor and the touch strength increase coefficient, the adjusted touch strength range is used as the currently set touch strength range again, and the adjusted touch strength range is used as the currently set touch strength range when the user performs current input in step S202.
When no marked code character exists in the code character string input last time and the user performs the check quitting operation, the currently set touch strength range is adjusted according to the touch strength range increase factor and the touch strength increase coefficient, the adjusted touch strength range is used as the currently set touch strength range again, and the adjusted touch strength range is used as the currently set touch strength range when the user performs the current input in step S202.
The touch strength range increase factor and the touch strength increase coefficient may be set by those skilled in the art according to actual needs, and are not particularly limited in the embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, the currently set touch strength range in step S202 is obtained by adjusting the corresponding touch strength range when the encoded character string is input last time, only by way of example. In the specific implementation process, the touch force range currently set in step S202 may be obtained by adjusting the touch force range corresponding to the last input of the encoded character string n times or the touch force range corresponding to the input of the encoded character string within the last period of time, without being limited thereto.
Step S204: and receiving the code characters and simultaneously determining the touch control strength when the code characters are input.
When the user uses the input method, the required entries are obtained by inputting the code character strings. When inputting the code character string, one or more code characters are required to be input. In this step, the input method client receives each input code character and obtains the touch strength when the user inputs the code character.
Step S206: judging whether the touch control strength corresponding to the code character falls outside a currently set touch control strength range or not; if yes, go to step S208, otherwise, go to setup operation.
If the touch force falls outside the currently set touch force range, the corresponding code character is indicated as being input by mistake, and if the touch force falls within the currently set touch force range, the corresponding code character is indicated as being input intentionally.
The setting operation may be a flag for the code character determined to be incorrectly input.
Step S208: and when the touch control strength corresponding to the code character is out of the current set touch control strength range, marking the code character.
The purpose of marking the code characters is to distinguish the code characters input by mistake by the user from the code characters input by intention by the user. The specific form of the mark may be set by those skilled in the art according to actual needs in specific implementation processes, which are not specifically limited in the embodiments of the present invention.
Step S210: judging whether the input of the first coding character string is finished; if so, go to step S212, otherwise, go back to step S204.
Since the first encoded character string may include a plurality of encoded characters, and the above steps S204 and S208 are only operations on one encoded character, it is necessary to determine whether there are any encoded characters that are not input after the operation on one encoded character is completed in this step. If yes, step S204 to step S208 are repeatedly executed until the first code string is completely input.
The specific determination method of whether the first code string is completely input may be set by a person skilled in the art according to actual requirements. For example: if no new code character is received beyond the set time, the first code character string is determined to be input completely.
Step S212: and when the input of the first code character string is finished, deleting the marked code characters in the first code character string to generate a second code character string.
The marked code character is the code character input by the user by mistake, and the error correction of the first code character string can be finished by deleting the marked code character in the first code character string in the step.
Step S214: and determining a candidate entry corresponding to the first coding character string.
It should be noted that step S214 is not limited to be executed after step S212, and step S214 may also be executed before step S212 or in parallel with step S212.
Step S216: and determining a candidate entry corresponding to the second encoding character string.
For the specific operation of determining the candidate entry corresponding to the encoded character string, reference may be made to related technologies, which is not specifically limited in the embodiment of the present invention. For example: firstly, segmenting the coded character string, and then determining candidate entries according to the segmentation result.
It should be noted that step S216 is not limited to be executed after step S214, and step S216 may be executed at any time after the first code string is input and before step S220.
Step S218: and carrying out error correction on the coding characters adjacent to the key positions on the first coding character string to generate a third coding character string, and determining a candidate entry corresponding to the third coding character string.
One preferred way to perform error correction of code characters adjacent to the key positions on the first code character string and generate the third code character string is as follows:
s1: determining the marked code character in the first code character string;
s2: finding out at least one code character adjacent to the marked code character from the adjacent key position table;
s3: and correspondingly replacing the marked code character in the first code character string with the adjacent code character to generate a third code character string.
If the first code string contains a plurality of marked code characters, then when the code characters adjacent to the key positions are corrected, only the code character adjacent to one marked code character can be searched from the adjacent key position table, and then, only the one marked code character is replaced to generate the third code string. Of course, two or three code characters adjacent to the marked code character can be searched from the adjacent key mapping table, and the marked code characters in the first code character string are respectively replaced correspondingly to generate the third code character string.
The third encoding string may be a string of characters or may be a plurality of strings of characters. When the third encoded character string is a multi-string encoded character string, candidate entries corresponding to the plurality of encoded character strings may be determined, respectively. One or more optimal encoding strings can be selected, and only the candidate entries corresponding to the optimal encoding strings are determined.
In the embodiment of the invention, the error correction processing is carried out on the first coding character string by combining two error correction modes of adjacent key position error correction and touch control strength range error correction. Compared with the mode of only correcting errors according to the adjacent key positions or only correcting errors according to the touch force range, the method can improve the accuracy of error correction and further improve the reliability of candidate entries pushed to the user.
In a specific implementation process, step S218 may not be executed, and the error correction may be performed on the encoded character string only according to the touch strength range.
Step S220: and sequencing and displaying the candidate entries according to a set rule.
In this embodiment, the candidate entries include: the candidate entries corresponding to the first encoded character string, the candidate entries corresponding to the second encoded character string, and the candidate entries corresponding to the third encoded character string.
When the candidate entries are sorted, reference may be made to a technology for sorting and displaying the candidate entries, which is not specifically limited in the embodiment of the present invention. For example: the ranking is based on the type, word frequency, context, time, location, application environment, user type, etc. of the candidate entries.
After the candidate entries are displayed in sequence, the user can browse the candidate entries and select the required entries from the candidate entries on the screen, and of course, the user can also perform a backspace operation and re-input a new code string. At this time, the input rule adjusts the currently set touch force range in step S202 according to the specific operation of the candidate entry by the user.
Step S222: and adjusting the currently set touch control force range.
The new touch control strength range obtained by adjusting the currently set touch control strength range can be used as the currently set touch control strength range corresponding to the input of the next encoded character string.
Four preferred ways of adjusting the currently set touch force range are as follows:
first preferred mode: when the marked code character does not exist in the input first code character string and the candidate entry corresponding to the first code character string is displayed on the screen by the user, the currently set touch control force range is kept unchanged.
Second preferred mode: and when the marked code characters exist in the input first code character string and the candidate entries corresponding to the code character string after error correction are displayed on the screen of the user, keeping the currently set touch control force range unchanged.
Third preferred mode: when the marked code characters exist in the input first code character string and the candidate entries corresponding to the code character string are not corrected by the user on the screen, the currently set touch control strength range is adjusted according to the touch control strength range increasing factor and the touch control strength increasing coefficient, and the currently set touch control strength range is updated to the adjusted touch control strength range to serve as a basis for marking the mistakenly input code characters when the user inputs the code character string next time.
In the embodiment of the present invention, the setting of the touch force range increase factor and the touch force increase coefficient is not specifically limited in the embodiment of the present invention. The specific way of adjusting the currently set touch strength range with reference to the two parameters can also be set to any feasible way by those skilled in the art according to actual requirements.
For example, the following settings may be made: assuming that the currently set touch strength range is [ x, y ], the adjusted currently set touch strength range is [ x ', y' ], the touch strength range growth factor is d, and the touch strength growth coefficient is w. If the minimum touch force in the process of inputting the first code character string by the user is less than x, x' is x-w d; and if the minimum touch strength in the process of inputting the first code character string by the user is greater than y, y + w.
Fourth preferred mode: when the marked code character does not exist in the input first code character string and the user executes the check quitting operation, the currently set touch control strength range is adjusted according to the touch control strength range increasing factor and the touch control strength increasing coefficient, and the currently set touch control strength range is updated to the adjusted touch control strength range to serve as the basis for marking the code character which is input by mistake when the user inputs the code character string next time.
In the embodiment of the present invention, the setting of the touch force range increase factor and the touch force increase coefficient is not specifically limited in the embodiment of the present invention. The specific manner of adjusting the currently set touch strength range with reference to the two parameters may also be set to any feasible manner by those skilled in the art according to actual requirements.
For example, the following settings may be made: assuming that the currently set touch strength range is [ x, y ], the adjusted currently set touch strength range is [ x ', y' ], the touch strength range growth factor is d, and the touch strength growth coefficient is w. If the minimum touch strength in the process of inputting the first code character string by the user is greater than x, x' is x + w x d; and if the minimum touch strength in the process of inputting the first code character string by the user is less than y, y' -y-w x d.
The input method error correction method provided by the embodiment of the invention has the beneficial effects of the input method error correction method in the first embodiment, and can automatically learn the habitual pressing pressure degree (namely the currently set touch force range) of the touch screen of the user, thereby better meeting the actual requirements of the user and improving the use experience of the user.
Referring to fig. 3, a description is given of an input method error correction flow according to an embodiment of the present invention.
The input method error correction process in this specific example includes the following steps:
step S302: and (4) starting the input method client by the user, and setting the touch control force range during normal input.
The currently set touch control force range reflects the pressing force degree of the user habit. For the determination of the currently set touch strength range, the setting manner shown in the second embodiment may be referred to, and details thereof are not repeated in this specific example.
Step S304: and (3) inputting the code characters by a user, identifying the pressing force of the user by an input method, comparing the pressing force with the touch force range during normal input, and marking error correction.
In the embodiment of the present invention, the specific example is described by taking the input first code character string as an alphabetic sequence. The pressing force of the user is the touch force when the user inputs letters.
The user inputs letters to be input in sequence, in the process, the user may touch other keys by mistake, the input method can identify the touch strength of each key of the user, then the touch strength is compared with the touch strength range of normal input of the user, and if the touch strength of the user is not in the touch strength range of normal input of the user, error correction marks are made on the letters input at the time. The input of the touch force range when the touch force is in the normal input is regarded as the normal input.
Step S306: judging whether letters are input; if yes, the process returns to step S304, otherwise, step S308 is performed.
And when the letters are input, circularly executing the steps S304 to S306 until no letters are input or the letter sequence is input.
Step S308: and the input method kernel conversion module converts the original input letter sequence to obtain the candidate queue 1 without error correction.
In this step, the input method kernel performs a normal conversion process. The input method kernel conversion module converts the original input sequence, such as syllable division, pinyin conversion, word stock search and word filling, and candidate frequency modulation sequencing, and finally obtains a candidate queue 1 without error correction. Candidate queue 1 is the candidate entry corresponding to the original input letter sequence.
Step S310: and the input method kernel error correction module constructs a new input letter sequence according to the touch strength error correction mark and converts the new letter sequence to obtain an error correction candidate queue 2.
The input method kernel error correction module corrects the letter sequence input by the user according to the error correction marks of the letters in the letter sequence, discards letters (namely the letters marked with the error correction marks) with touch control strength not in the touch control strength range when the user normally inputs the letters, constructs an error correction letter sequence, and then performs corresponding conversion and other processing on the constructed error correction letter sequence to obtain an error correction candidate queue 2 corresponding to the error correction letter sequence.
In the step S310, when the touch strength-based error correction is performed on the original input letter sequence, the method can be used in combination with a position error correction method based on adjacent key positions, and when the letter with touch strength not in the range of the touch strength of the normal input of the user is discarded, the error corrected letter sequence a is obtained. And constructing a plurality of error-corrected letter sequences B based on the position error correction of adjacent keys, specifically, constructing a plurality of error-corrected letter sequences (for example, performing adjacent key position replacement on one or more letters) by searching an adjacent key position table and correspondingly replacing letters in the input sequence. Then, the error correction letter sequence A and the plurality of error correction letter sequences B are sequenced according to the language model of the error correction sequence, and the optimal error correction letter sequence is selected for the conversion, so that the error correction candidate queue 2 is obtained.
Of course, it is also possible to select an optimal error correction alphabet sequence from the plurality of error correction alphabet sequences B, and then use both the error correction alphabet sequence a and the selected optimal error correction alphabet sequence as the error correction candidate sequence 2.
S312: and the input method kernel merges the candidate queue 1 and the error correction candidate queue 2 according to the candidate entry type, the word frequency, the language model of the letter sequence and the like, and returns to the merged queue.
And checking the queue 1 and the error correction candidate queue 2 which do not contain error correction candidates in the input method, merging according to the types of the candidate words, the word frequency and the like, sequencing all the candidate entries in the candidate queue, returning all the candidate entries to the front end of the input method according to the sequencing for displaying, and enabling a user to select to screen.
The following describes an input method error correction process of this specific example, taking as an example that a user inputs an alphabet sequence through a qwerty26 keyboard of a mobile phone, where a touch force range during normal input by the user is Pr [ x, y ], and the user intends to continue inputting an error input and error correction process of "habit" ("xiguan") after the last screen-on operation. The specific process is as follows:
(1) in the process that the fingers of the user move from the candidate frame to the 'x' key, the 'w' key is erased by mistake, the pressing pressure of the user is identified by the input method and is not in the range of the touch force when the user normally inputs, and therefore an error correction mark is marked on the 'w' letter;
(2) pressing an 'x' key by a user finger, and identifying the pressing pressure degree of the user by an input method, wherein the pressing pressure degree is within the touch control force range when the user normally inputs; therefore, the 'x' alphabet is not marked with an error correction flag;
(3) the finger of the user moves from the 'x' key to the 'i' key, the 'g' key is touched by mistake, the pressing pressure of the user is identified by the input method and is not in the touch force range during normal input of the user, and therefore an error correction mark is marked on the 'g' letter;
(4) pressing keys of 'i', 'g' and 'u' by fingers of a user, and identifying the pressing pressure degree of the user and the touch force range when the user normally inputs the input method; therefore, the error correction flag is not marked for the three letters;
(5) the user fingers move from the 'u' key to the 'a' key, the'd' key is touched by mistake, and the input method identifies the pressing pressure degree of the user and is not in the touch control force range when the user normally inputs; therefore, the'd' alphabet is marked with an error correction flag;
(6) pressing an 'a' key by a user finger, and identifying the pressing pressure degree of the user by the input method, wherein the pressing pressure degree is within the touch control force range when the user normally inputs; therefore, the 'a' alphabet is not marked with an error correction flag;
(7) the user fingers move from the 'a' key to the 'n' key, the 'f' key is touched by mistake, and the input method identifies the pressing pressure degree of the user and is not in the touch control force range when the user normally inputs the input; thus, the 'f' alphabet is error-correction marked;
(8) pressing an 'n' key by a user finger, and identifying the pressing pressure degree of the user by an input method, wherein the pressing pressure degree is within the touch control force range when the user normally inputs; therefore, the 'n' alphabet is not marked with an error correction flag;
(9) the kernel converts the letter sequence 'wxgugdafn' input by the user, the error correction module discards the letters subjected to error correction marking by analyzing the error correction marking to obtain the letter sequence 'xiguan' input by the user intention, and further performs letter sequence conversion to obtain a candidate entry 'habit', and returns the candidate entry 'habit' to the user.
The input method identifies the touch strength when each letter is input by the user, compares the touch strength with the touch strength range when the user normally inputs the letter, and corrects the letter sequence by abandoning the letters with the pressure degree not in the touch strength range when the user normally inputs the letter. The error correction method is not only suitable for judging the mis-input caused by the adjacent key position, but also suitable for judging the mis-input caused by the non-adjacent key position, so that the error correction accuracy of the input method can be improved, and the candidate entries with high reliability are provided for the user. Furthermore, the candidate entries with high reliability can be provided for the user, so that backspace deleting operation of the user can be reduced, and input experience of the user is improved.
