Technical Field

The present disclosure relates to the field of image character recognition, and in particular, to a method and an apparatus for Chinese character recognition and error correction, a computer readable medium, and an electronic device.

Background

At present, the encoding of the chinese characters mostly adopts a one-hot code (one-hot code) mode, so that 7445 chinese characters and graphic characters exist in a chinese character information base, and the dimension for representing the encoding of each chinese character and graphic character is seven thousand or more, which is a very large and bloated encoding mode. In addition, in this coding method, since there is no correlation between the chinese characters represented by the adjacent codes, it is not possible to know what the image shown in the original image is in the case of a recognition error, and it is very inconvenient to correct the recognized chinese characters.

FIG. 1 is a schematic diagram illustrating one implementation environment in accordance with an example embodiment. As shown in fig. 1, the implementation environment may include a server 100 and at least one client 200.

In the present disclosure, the server 100 is in communication connection with each client 200, wherein the two may communicate via a 2G network, a 3G network, a 4G network, bluetooth, WIFI, etc. to complete data transmission. After the image is subjected to Chinese character recognition, the client 200 may send one or more Chinese characters to be corrected, which are not recognized correctly, to the server 100, so that the server 100 provides a correction suggestion. In addition, the client 200 may be, for example, a smart phone, a tablet computer, or the like, and is not particularly limited in this disclosure.

Specifically, the server 100 may provide the error correction suggestion to the corresponding client 200 through steps 201 to 204 shown in fig. 2.

In step 201, a chinese character error correction request sent by a client is received, where the chinese character error correction request includes a chinese character to be error corrected.

In the present disclosure, after performing chinese character recognition on an image, when there is a recognition error, the client 200 may send a chinese character error correction request including one or more chinese characters to be error corrected to the server 100; the server 100 receives the chinese character correction request.

In step 202, the code of the Chinese character to be corrected is determined.

In the present disclosure, the above codes are used to represent components and structural relationships among components included in a chinese character to be corrected, where the components may include components and radicals, and the structural relationships among the components are to morphologically summarize the structure of the chinese character into an upper-lower structure, a left-right structure, and other structures (e.g., an upper-middle-lower structure, a left-middle-right structure, a full-enclosure structure, a half-enclosure structure, an insertion structure, a delta-shape structure, a single-body structure, etc.).

The codes corresponding to the Chinese characters are stored in the Chinese character information base, so that when the Chinese character error correction request sent by the client 200 is received through the step 201, the codes corresponding to the Chinese characters to be error corrected can be obtained by accessing the corresponding storage modules of the Chinese character information base.

In addition, in one embodiment, the code corresponding to each Chinese character in the Chinese character information base can be determined through steps 301 to 303 shown in FIG. 3.

In step 301, for each chinese character in the chinese character information base, the components included in the chinese character and the structural relationship between the components are obtained.

In the present disclosure, since the specific manner of obtaining the structural relationship between the components and the components is well known to those skilled in the art, the detailed description thereof is omitted here.

In step 302, for each component, the element value in the first code sequence corresponding to the component is modified to a first bit value, resulting in a second code sequence.

In this disclosure, the first coding sequence may be a binary bit sequence in which each element value is a second bit value, and each component or structural relationship among components in the component structure set corresponds to each element in the first coding sequence one to one (that is, the length of the first coding sequence is equal to the number of elements included in the component structure set), where the component structure set may be a set formed by components and structural relationships among components included in all chinese characters in the chinese character information library.

The first bit value is 1, and the second bit value is 0; alternatively, the first bit value is 0 and the second bit value is 1.

Illustratively, if 300 parts are included in all the chinese characters in the chinese character information library and 50 structural relationships are included in the chinese characters, the length of the first coding sequence is 350, where the 300 parts and 50 structural relationships are respectively in one-to-one correspondence with 350 elements in the first coding sequence.

In step 303, for each structural relationship between the components, the element value corresponding to the structural relationship between the components in the second coding sequence is modified into the first bit value, so as to obtain the code corresponding to the chinese character.

The following illustrates how each chinese character in the chinese character information base is encoded through the above steps 301 to 303.

Illustratively, the chinese character is "part", and the parts included in the chinese character obtained in step 301 are "vertical", "oral" and "", where the structural relationship of each part is left-right structure + top-bottom structure; then, element values corresponding to three parts of 'vertical', 'mouth', '' in the first coding sequence are modified into a first bit value (for example, 1) respectively, and a second coding sequence is obtained; next, the element values corresponding to the "left-right structure" and the "top-bottom structure" in the second coding sequence are modified to the first bit value (for example, 1), whereby the code corresponding to the "part" of the chinese character can be obtained.

Further, for example, the chinese character is "middle", the component included in the chinese character is "middle" obtained in step 301, and the component structure relationship is a single-body structure; then, modifying the element value corresponding to the component "middle" in the first code sequence into a first bit value (for example, 1) to obtain a second code sequence; next, the element value corresponding to the "one-body structure" in the second coding sequence is modified to the first bit value (for example, 1), so that the code corresponding to the "middle" Chinese character can be obtained.

In another embodiment, firstly, aiming at each Chinese character in a Chinese character information base, acquiring components contained in the Chinese character and structural relations among the components; then, aiming at the structural relationship among the components, modifying the element value corresponding to the structural relationship among the components in the first coding sequence into a first bit value to obtain a second coding sequence; finally, aiming at each part, modifying the element value corresponding to the part in the second coding sequence into a first bit value to obtain the code corresponding to the Chinese character.

In another embodiment, the code corresponding to each Chinese character in the Chinese character information base can be determined through steps 401 to 404 shown in FIG. 4.

In step 401, for each chinese character in the chinese character information base, the components included in the chinese character and the structural relationship between the components are obtained.

In step 402, for each part, the element value corresponding to the part in the third encoded sequence is modified to a first bit value, resulting in a fourth encoded sequence.

In this disclosure, the third coding sequence is a binary bit sequence in which each element value is a second bit value, and each component in the component set corresponds to each element in the third coding sequence one to one, where the component set is a set formed by components included in all chinese characters in the chinese character information base.

Illustratively, if there are 300 parts included in all the chinese characters in the chinese character information library, the length of the third encoding sequence is 300, where the 300 parts are respectively in one-to-one correspondence with 300 elements in the third encoding sequence.

In step 403, for each structural relationship between the components, the element value corresponding to the structural relationship between the components in the fifth coding sequence is modified into the first bit value, so as to obtain a sixth coding sequence.

In this disclosure, the fifth coding sequence is a binary bit sequence in which each element value is a second bit value, and the structural relationships among the parts in the structural set correspond to the elements in the fifth coding sequence one to one, where the structural set is a set formed by the structural relationships among the parts included in all the chinese characters in the chinese character information base.

Illustratively, 50 structural relationships among components included in all the chinese characters in the chinese character information library are present, and the length of the fifth encoding sequence is 50, where the 50 structural relationships among the components respectively correspond to 50 elements in the fifth encoding sequence one to one.

In step 404, the fourth coding sequence and the sixth coding sequence are spliced to obtain a code corresponding to the Chinese character.

In the present disclosure, after the fourth coding sequence is obtained in step 402 and the sixth coding sequence is obtained in step 403, the sixth coding sequence may be spliced to the tail of the fourth coding sequence, or the fourth coding sequence may be spliced to the tail of the sixth coding sequence, so as to obtain the code corresponding to the chinese character.

Note that, the step 403 may be executed before the step 402, may be executed after the step 402, may be executed simultaneously with the step 402, and is not particularly limited in the present disclosure.

The following illustrates how each Chinese character in the Chinese character information base is encoded through the above steps 401 to 404.

Illustratively, the chinese character is "part", and the parts included in the chinese character obtained in step 401 are "vertical", "oral" and "", where the structural relationship of each part is left-right structure + top-bottom structure; then, element values corresponding to three components of "vertical", "horizontal", "" in the third code sequence are modified to a first bit value (for example, 1) to obtain a fourth code sequence, and element values corresponding to "left and right structures" and "upper and lower structures" in the fifth code sequence are modified to a first bit value (for example, 1) to obtain a sixth code sequence; finally, the fourth coding sequence and the sixth coding sequence are spliced, and therefore codes corresponding to the parts of the Chinese characters can be obtained.

Further, for example, the chinese character is "middle", the component included in the chinese character is "middle" obtained in step 401, and the component structure relationship is a single-body structure; then, modifying the element value corresponding to the part of 'middle' in the third coding sequence into a first bit value (for example, 1) to obtain a fourth coding sequence, and modifying the element value corresponding to the 'individual body structure' in the fifth coding sequence into the first bit value (for example, 1) to obtain a fourth six coding sequence; finally, the fourth coding sequence and the sixth coding sequence are spliced, and therefore the corresponding code of the Chinese character 'middle' can be obtained.

In addition, the structural relationship between the components may have a plurality of different division rules, for example: "Xie Ji", can be defined as the independent structure, also can be defined as the upper and lower structure; "escape" may be defined as an upper-lower structure, a left-right structure, or the like.

Returning to fig. 2, in step 203, a target chinese character similar to the chinese character to be corrected is determined from the plurality of preset chinese characters according to the codes corresponding to the plurality of preset chinese characters stored in the chinese character information base and the code of the chinese character to be corrected.

In this disclosure, the preset Chinese characters do not include the Chinese character to be corrected obtained in step 201. Moreover, the preset chinese characters may be preset by the user or may be default (for example, the preset chinese characters include other chinese characters in the chinese character information base except the chinese character to be corrected, or the preset chinese characters include other chinese characters in the common chinese character except the chinese character to be corrected), and are not limited in this disclosure.

In one embodiment, the codes corresponding to the preset Chinese characters and the codes of the Chinese characters to be corrected are matched for each preset Chinese character in the preset Chinese characters; and if the matching rate is greater than the preset matching rate threshold value, determining that the preset Chinese character is similar to the Chinese character to be corrected, and determining the preset Chinese character as the target Chinese character. The preset matching rate threshold may be set by a user according to a coding length, or may be default, and is not specifically limited in this disclosure.

For example, if there are 350 parts and structural relationships between the parts included in all the chinese characters in the chinese character information library, the matching rate threshold may be set to 69/70.

In another embodiment, the target kanji may be determined through step 2031 and step 2032 shown in fig. 5.

In step 2031, for each preset chinese character, the similarity between the code corresponding to the preset chinese character and the code of the chinese character to be corrected is calculated.

In the present disclosure, the similarity between the code corresponding to each preset Chinese character and the code of the Chinese character to be corrected can be calculated by the euclidean distance, the cosine distance, the hamming distance, and the like.

In step 2032, if it is determined according to the similarity that the preset chinese character corresponding to the similarity is similar to the chinese character to be corrected, the preset chinese character corresponding to the similarity is determined as the target chinese character.

In an embodiment, when the similarity is greater than a first preset similarity threshold, it may be determined that the preset chinese character corresponding to the similarity is similar to the chinese character to be corrected.

For example, in step 2031, the euclidean distance or the cosine distance is used to calculate the similarity between the code corresponding to each preset chinese character and the code of the chinese character to be corrected, so that when the similarity is greater than the first preset similarity threshold, it may be determined that the preset chinese character corresponding to the similarity is similar to the chinese character to be corrected.

In another embodiment, when the similarity is smaller than a second preset similarity threshold, it may be determined that the preset chinese character corresponding to the similarity is similar to the chinese character to be corrected.

Illustratively, the step 2031 calculates the similarity between the code corresponding to each preset chinese character and the code of the chinese character to be corrected by using the hamming distance, so that when the similarity is smaller than the second preset similarity threshold, it can be determined that the preset chinese character corresponding to the similarity is similar to the chinese character to be corrected.

In addition, it should be noted that the first preset similarity threshold and the second preset similarity threshold may be set by a user, or may be default empirical values, and the two may be equal or unequal, which is not specifically limited in this disclosure.

Returning to fig. 2, in step 204, the target chinese character is sent to the client for presentation by the client.

In the present disclosure, after the target chinese character similar to the chinese character to be corrected is obtained in step 203, the target chinese character may be sent to the client; the client receives and displays the target Chinese character.

In the technical scheme, after a Chinese character error correction request sent by a client is received, firstly, the codes of Chinese characters to be corrected contained in the request to be corrected are determined; then, according to codes corresponding to a plurality of preset Chinese characters stored in a Chinese character information base and codes of Chinese characters to be corrected, target Chinese characters similar to the Chinese characters to be corrected are determined from the preset Chinese characters; and finally, feeding the target Chinese character back to the client side to be displayed at the client side. Because the codes adopted by the Chinese characters in the method can represent the components contained in the corresponding Chinese characters and the structural relationship among the components, the same components or structures exist among the Chinese characters with similar codes. Therefore, the target Chinese character which is determined according to the corresponding codes of the Chinese characters and is similar to the Chinese character to be corrected has correlation with the Chinese character to be corrected, so that the target Chinese character which has correlation with the Chinese character to be corrected is used for correcting the Chinese character to be corrected, and the correction accuracy and the correction efficiency can be improved.
