For step S201, according to some embodiments, the text fragment to be processed is one sentence in a text to be processed.
According to some embodiments, the text to be processed may be divided into a plurality of text fragments to be processed with a sentence as a unit through one or more manners of recognition on punctuations in the text to be processed or semantic analysis, etc.
According to some embodiments, all character positions in the text fragment to be processed may be sequentially determined as the target position, and then processing on the target position is performed.
According to some embodiments, positions where one or more characters with the lower confidence degree in the text fragment to be processed are located may be determined as the target position by utilizing a trained model, and then processing on the target position is performed.
According to some embodiments, prior to the determining a first probability value of each candidate character of a plurality of candidate characters corresponding to a target position based on character feature information corresponding to the target position in a text fragment to be processed, fragment feature information of the text fragment to be processed and fragment feature information of each of a plurality of reference text fragments are determined respectively, wherein the plurality of reference text fragments and the text fragment to be processed are from the same text to be processed; overall feature information of the text fragment to be processed is determined based on the fragment feature information of the text fragment to be processed and the fragment feature information of each of the plurality of reference text fragments; and the character feature information corresponding to the target position in the text fragment to be processed is determined based on the overall feature information of the text fragment to be processed.
Thus, the character feature information corresponding to the target position may be fused with information of a plurality of text fragments in the whole text to be processed and is not only limited to the text fragment to be processed itself, so that the determined character feature information corresponding to the target position can, under the context of the whole text to be processed, more accurately reflect a feature of a correct character that should appear at the target position, thereby improving the accuracy of error correction.
It can be understood that the fragment feature information of the text fragment to be processed is a feature of the text fragment to be processed represented under the context of the text fragment to be processed itself, and the fragment feature information of each of the plurality of reference text fragments is a feature of the reference text fragment represented under the context of the reference text fragment itself. The overall feature information of the text fragment to be processed is a feature of the text fragment to be processed represented under the context of the whole text fragment to be processed.
According to some embodiments, a set composed of the plurality of reference text fragments may be other parts except the text fragment to be processed in the text to be processed.
According to some embodiments, the text fragment to be processed may be input to a trained first module to obtain the fragment feature information of the text fragment to be processed.
According to some embodiments, each of the plurality of reference text fragments may be input to a trained first module to obtain the fragment feature information of each of the plurality of reference text fragments.
According to some embodiments, the fragment feature information of the text fragment to be processed and the fragment feature information of each of the plurality of reference text fragments may be input to a trained second module at the same time to obtain the overall feature information of the text fragment to be processed.
According to some embodiments, the determining overall feature information of the text fragment to be processed based on the fragment feature information of the text fragment to be processed and the fragment feature information of each of the plurality of reference text fragments includes: the overall feature information of the text fragment to be processed is determined by utilizing a multi-head-attention mechanism.
According to some embodiments, the plurality of candidate characters corresponding to the target position may be all characters included in a preset character set.
For step S202, according to some embodiments, the determining a second probability value of the candidate character includes: in response to that the character string including the candidate character and the at least one character corresponding to at least one position in the text fragment to be processed adjacent to the target position is a pre-stored entity word, it is determined that the second probability value of the candidate character is a positive number, wherein the pre-stored entity word is determined based on entity word recognition performed on remaining fragments other than the text fragment to be processed in a text to be processed.
Thus, in the case that the character string including a certain candidate character is an entity word that has appeared in other parts of the text to be processed, a probability value corresponding to the candidate character may be increased, and then the possibility that the candidate character is determined as the correction character is improved, avoiding the problem that unusual words in entity words are wrongly corrected.
According to some embodiments, the entity word may further include a naming entity word. The naming entity word may be a person's name, an institute's name, a place name and all other entities with names as identifications.
According to some embodiments, before the second probability value of the candidate character is determined, entity word recognition is performed on the plurality of reference text fragments by utilizing an entity word recognition model, and recognized entity words are stored in an entity word set.
According to some embodiments, the entity word recognition model is used to perform entity word recognition on the character string including the candidate character in the text fragment to be processed and the at least one character corresponding to at least one position in the text fragment to be processed adjacent to the target position; in the case that the entity word is recognized from the character string, the recognized entity word may be compared with each entity word in the entity word set; and the recognized entity word is determined as the pre-stored entity word in response to that the recognized entity word is consistent with any entity word in the entity word set.
According to some embodiments, the second probability value of the candidate character is in positive correlation with a number of times that the pre-stored entity word is applied in the remaining fragments of the text to be processed. Thus, in the case that an entity word including the candidate character frequently appears in the remaining fragments of the text to be processed, the candidate character is given a higher second probability value, so as to increase the probability that the candidate character is determined as the correction character.
According to some embodiments, in response to that the character string including the candidate character and the at least one character corresponding to at least one position in the text fragment to be processed adjacent to the target position is not a pre-stored entity word, it is determined that the second probability value of the candidate character is zero.
After the first probability value and the second probability value of each candidate character of the plurality of candidate characters are determined, step S203 may be further executed, that is, the correction character at the target position is determined based on the first probability value and the second probability value of each candidate character of the plurality of candidate characters.
According to some embodiments, the determining a correction character at the target position based on the first probability value and the second probability value of each candidate character of the plurality of candidate characters may include: a weighted sum of the first probability value and the second probability value of each candidate character of the plurality of candidate characters is determined; and an candidate character with the largest weighted sum in the plurality of candidate characters is determined as the correction character.
As shown in ”, and stores the “
” in an entity word set as a pre-stored entity word.
S1, S2 and S3 are input to an encoder 302 respectively to be coded so as to obtain overall feature information of the text fragment to be processed S3. In some embodiments, the encoder 302 may be composed of a first module and a second module. The first module codes S1, S2 and S3 respectively to obtain fragment feature information corresponding to S1, S2 and S3 respectively. The fragment feature information corresponding to S1, S2 and S3 respectively is input to the second module to obtain the overall feature information of the text fragment to be processed S3.
Based on the overall feature information of the text fragment to be processed S3, a decoder 303 may sequentially use positions where all characters in input S3 are located as a target position, and then S3 is corrected. For example, as shown in ” in S3 is located is used as the target position, a first probability value of each candidate character of the plurality of candidate characters corresponding to the target position is determined based on the overall feature information of the text fragment to be processed S3, wherein the candidate characters include: “
”, “
”, etc. For “
” in the plurality of candidate characters, since the character string “
” including “
” and characters at front and back positions in S3 adjacent to the target position is a pre-stored entity word, the candidate character “
” may be given a positive second probability value to increase a total probability value of the candidate character “
”. Finally, based on a weighted sum of the first probability value and the second probability value of each candidate character, it is determined that the candidate character “
” is a correction character, and corrected S3′ is output.
It can be understood that it is only for the ease of expression by adopting two sentences S1 and S2 as reference text fragments in
According to some embodiments, the second determining unit includes: a sub-unit, configured to determine, in response to that the character string including the candidate character and the at least one character in at least one position in the text fragment to be processed adjacent to the target position is a pre-stored entity word, that the second probability value of the candidate character is a positive number, wherein the pre-stored entity word is determined based on entity word recognition performed on remaining fragments other than the text fragment to be processed in a text to be processed.
According to some embodiments, the second probability value of the candidate character is in positive correlation with a number of times that the pre-stored entity word is applied in the remaining fragments of the text to be processed.
According to some embodiments, the second determining unit includes: a sub-unit, configured to determine, in response to that the character string including the candidate character and the at least one character in at least one position in the text fragment to be processed adjacent to the target position is not a pre-stored entity word, that the second probability value of the candidate character is zero.
