Description

Technical Field

[0002] Document information processing involves information search, derivation, comparison and other operations based on keywords in documents.

In addition, some existing technologies can derive document information based on artificial intelligence big models. Although this information derivation method can ensure the processing efficiency of massive document information, it is necessary to use massive historical data to train and continuously adjust the model before the artificial intelligence big model is put into production, until the artificial intelligence big model can meet the user's use needs, and in the process of putting the model into production, it is necessary to pay time and economic costs for model maintenance.

[0047] Step S201, obtaining a document to be processed and a reference document;

[0048] Step S202, preprocessing the document to be processed to obtain a first processing result, and preprocessing the reference document to obtain a second processing result, wherein the first processing result is at least used to determine a first keyword, which is a keyword to be derived in the document to be processed, and the second processing result is at least used to determine a second keyword, which is a keyword to be derived in the reference document;

[0050] Step S204, performing a difference comparison between the information collection to be compared and the reference information collection to obtain a target information collection, wherein the target information collection is used to characterize the difference between the information collection to be compared and the reference information collection.

[0051] The above-mentioned to-be-processed document is a document that the user needs to compare information with, and the above-mentioned reference document can be a standard reference document determined by the user for comparing and determining the difference status of the to-be-processed document. It should be noted that the number of reference documents can be adjusted by the user as required. When there are multiple reference documents, the to-be-compared information collection can be compared with the reference information collection corresponding to each reference document to determine the information difference status between the to-be-processed document and different reference documents.

[0052] In the present invention, the preprocessing process of the document to be processed and the reference document may include: segmentation, keyword matching, and structural division after analysis and processing, wherein the analysis and processing process is used to analyze the structure and semantics of the document, the keyword matching process is used to determine the keywords to be derived in the document, and the structural division process is used to determine the preceding and succeeding text information corresponding to each keyword to be derived, the preceding text information is used to participate in the information derivation process of the keyword to be derived, and the succeeding text information is used to match the demand information corresponding to the derived information derived from each keyword to be derived.

[0053] The above-mentioned information collection to be compared is composed of the first derivative information corresponding to each first keyword and the first requirement information corresponding to the first derivative information, and the above-mentioned reference information collection is composed of the second derivative information corresponding to each second keyword and the second requirement information corresponding to the second derivative information. By performing a difference comparison according to the information group composed of the derivative information and the requirement information, the difference information in the document to be processed and the reference document can be quickly and accurately determined.

[0054] In an embodiment of the present invention, a document to be processed and a benchmark document are first obtained, then the document to be processed is preprocessed to obtain a first processing result, and the benchmark document is preprocessed to obtain a second processing result, wherein the first processing result is at least used to determine a first keyword, which is a keyword to be derived in the document to be processed, and the second processing result is at least used to determine a second keyword, which is a keyword to be derived in the benchmark document, and then information is derived from the first keyword based on the first processing result to obtain an information collection to be compared, and information is derived from the second keyword based on the second processing result to obtain a benchmark information collection, and finally, a difference comparison is performed between the information collection to be compared and the benchmark information collection to obtain a target information collection, wherein the target information collection is used to characterize the difference between the information collection to be compared and the benchmark information collection.

[0055] It is easy to understand that the above method determines the keywords to be derived in the processed document and the benchmark document and the preceding and following information of each derived keyword by performing refined preprocessing operations such as segmentation, keyword matching, and structural division on the processed document and the benchmark document, and then derives information from the derived keywords based on the processing results obtained from the preprocessing to obtain an information collection containing derived information and required information. Then, by performing a difference comparison between the information collection to be compared corresponding to the processed document and the benchmark information collection corresponding to the benchmark document, the purpose of accurately and efficiently processing the document information in a manner that can meet the user's customized needs is achieved, thereby achieving the technical effect of improving the accuracy and efficiency of document information processing and saving costs, and thus solving the technical problems of the prior art in that the document information processing accuracy is poor and the information deriving depends on large artificial intelligence models, resulting in high costs.

[0056] The above method of the embodiment of the present invention is further introduced below.

[0057] In an optional embodiment, in step S202, the document to be processed is preprocessed to obtain a first processing result including:

[0058] Step S221, using a document analyzer to analyze and process the document to be processed to obtain block information, wherein the block information is used to characterize the structure and semantics of the document to be processed;

[0059] Step S222, matching any keyword in the block information with any demand keyword to obtain a matching result, wherein any demand keyword is determined by a preset demand word library, and the matching result includes a first keyword and first position information, the first keyword is a keyword that successfully matches any demand keyword, and the first position information is used to determine the position of any first keyword in the block information;

[0060] Step S223, structurally divide the block information based on the matching results to obtain a first processing result, wherein the first processing result includes the first preceding context information corresponding to the first keyword and the first following context information corresponding to the first keyword, the first preceding context information is the information located before the position of the first keyword in the block information, and the first following context information is the information located after the position of the first keyword in the block information.

[0061] It should be noted that the document information processing process of the present invention is described in detail below by taking the operation steps of the preprocessing process and the information derivation process of the to-be-processed document and the reference document being identical as an example.

[0062] Figure 3 is a flowchart of an optional document information preprocessing process according to an embodiment of the present invention. Figure 3 As shown, the user first inputs the document to be processed and the benchmark document into the document information processing system, and inputs the preset demand vocabulary. Taking the preprocessing process of the document to be processed as an example, the system first uses the document analyzer to analyze and process the input document to be processed, analyzes the semantics and structure in the document to be processed, and divides the document information of the document to be processed into blocks according to the analysis results (such as dividing by punctuation marks) to obtain the above-mentioned block information.

[0063] Still Figure 3As shown, then, any keyword in the block information is matched with any demand keyword in the preset demand vocabulary, and the successfully matched keyword is used as the keyword to be derived (i.e., the first keyword) in the document to be processed, and the position of each first keyword in the block information is recorded to obtain the above-mentioned first position information. Further, the block information can be divided into information with a target structure according to the position of the first keyword. The target structure can be "keyword pre-context information + keyword + keyword post-context information". The present invention limits each target structure to only contain one keyword. After structural division, the preprocessing result of the document to be processed (i.e., the first processing result) is obtained. Then, information is derived from the first keyword according to the first processing result corresponding to the document to be processed, and information is derived from the second keyword according to the second processing result corresponding to the benchmark document, and the data collection obtained after the information derivation is compared to determine the document information difference between the document to be processed and the benchmark document.

[0064] It should also be noted that each piece of document information obtained after analyzing and processing the document information in the present invention corresponds to a number, and the number values ​​from small to large represent the order of the block information in the document information.

[0065] The above-mentioned preset demand word library may include at least one of the following: a common word library containing keywords frequently used by users in their daily work (such as words such as "substation", "line", "main transformer" in the power industry); a supplementary word library containing additional keywords of any keyword in the common word library; a special word library containing specific keywords in the document information processing task. It should be noted here that the document information processing method provided by the present invention will not derive information for specific keywords in the special word library, nor will it delete the position of the specific keyword in the first position information.

[0066] As an optional way to determine the context of keywords, such as Figure 4 As shown, first read all keyword positions corresponding to the current block information according to the first position information, determine whether the current block information contains the first keyword, and when the first keyword does not exist, merge the current block information into the post-context information corresponding to the last first keyword of the previous block information; when the first keyword exists, first pre-process each first keyword in the current block information, then remove the document information related to the first keyword that has been pre-processed from the current block information, and perform keyword existence judgment on the remaining document information of the current block information, and when it is further determined that the first keyword does not exist in the remaining document information, set the post-context information for the first keyword that has completed pre-processing.

[0067] As an optional implementation method of the keyword preprocessing process, Figure 5As shown, for any first keyword position, first determine whether there are other first keywords before the position. When it is determined that there are no other first keywords, determine that the keyword corresponding to the position remains unchanged, and use the beginning of the current block information as a derivative node. Next, obtain the document information between the derivative node and the position (recorded as keyword preceding information), and determine whether the keyword preceding information is empty. When it is determined that the keyword preceding information is not empty, determine whether there are conjunctions or prepositions before the position. When there are conjunctions or prepositions, use the position after the conjunction or preposition as the derivative point of the keyword corresponding to the position, and further obtain the field (including keywords) between the derivative point and the keyword corresponding to the position as the new keyword corresponding to the position. Further, it is determined whether the new keyword satisfies the derivation rationality condition. It should be noted here that the user can set the control content such as standard files, file groups, databases, etc. in advance according to their own needs. The determination of whether the new keyword satisfies the derivation rationality condition can be to determine whether the new keyword exists in the control content. When the new keyword satisfies the derivation rationality condition (that is, the new keyword exists in the control content), the position of the derivation point is moved forward by one position, and the field (including the keyword) between the new position of the derivation point and the new keyword is taken as the new keyword for the second update. It is further determined whether the new keyword after the second update meets the derivation rationality condition, and the preprocessing result of the first keyword is determined according to the judgment result, and the first keyword is adjusted according to the judgment result. The first previous text information corresponding to the keyword, specifically: when a new keyword meets the derivation rationality condition, the new keyword is used as the preprocessed keyword at the position (recorded as the position keyword), the derivative node corresponding to the position keyword is set to be consistent with the derivative node determined in the previous step of keyword previous text information judgment, and the previous text information corresponding to the position keyword is set to the document information between the derivative node and the position; when the new keyword after the second update does not meet the derivation rationality condition, the new keyword that is first judged whether it meets the derivation rationality condition is used as the preprocessed position keyword, and the position after the conjunction or preposition is used as the derivative node corresponding to the position keyword, and the previous text information corresponding to the position keyword is set to empty.

[0068] It should be noted that the unit document information can be customized by the user, for example: the unit document information is a Chinese character; for another example: the unit document information is a character.

[0069] like Figure 5 As shown, still in the above optional implementation, when it is determined that there is no conjunction or preposition before the position, the keyword in the previous step of determining whether the keyword preceding information is empty is determined as the preprocessed position keyword.

[0070] like Figure 5As shown, still in the above optional implementation, when it is first determined that the new keyword does not meet the derivative rationality condition, the keyword in the previous step of determining whether the keyword preamble information is empty is determined as the preprocessed position keyword, the derivative node is adjusted to the position two characters after the conjunction or preposition, and the document information between the adjusted derivative node and the preprocessed position keyword is used as the preamble information corresponding to the position keyword.

[0071] As Figure 5 shown, still in the above optional implementation, when there are other first keywords before the process start judgment position, the field between two adjacent first keywords before and after this position (including the two first keywords) is taken as the new keyword corresponding to this position. Then, it is judged whether the new keyword meets the derivative rationality condition. When it is determined that the new keyword meets the derivative rationality condition, the first keyword before this position to the field including the two first keywords before and after is taken as the newly updated keyword. At the same time, the two first keywords corresponding to this position, and the derivative node corresponding to the first keyword before this position are taken as the derivative node corresponding to the new keyword. Then, the subsequent preprocessing process is carried out according to the newly updated keyword and the corresponding derivative node. When it is judged that the new keyword does not meet the derivative rationality condition, it is judged whether there are auxiliary words (such as "de"), other symbols (such as spaces), etc. in the new keyword. When it is determined that there is such content, this content is deleted from the new keyword. When it is determined that there is no such content, it is judged whether the number of unit document information between the new keyword and the adjacent keyword before the position (denoted as P) meets the quantity condition. It should be noted that the user can preset the number of unit document information (denoted as N) of the minimum unit for the keyword matching process according to requirements. The above quantity judgment process can refer to judging whether the value P is greater than or equal to the sum of the quantity N and the value 1. When the quantity P meets the quantity condition, the keyword corresponding to this position is updated to the first keyword before the start of the preprocessing process, and the position of the (N + 1)-th unit document information after the position of the keyword before the current position is determined as the derivative node corresponding to the updated keyword corresponding to this position; when the quantity P does not meet the quantity condition, the keyword corresponding to this position is converted into ordinary document information and no longer participates in the subsequent preprocessing process and information derivation process.

[0072] As another optional implementation of the keyword preprocessing process, as Figure 6As shown, for any preprocessed position keyword (current position keyword), first determine whether there are other keywords before the position of the position keyword. When it is determined that there are other keywords, the post-context information of the current position keyword is set to the document information between the current position keyword and the adjacent keywords after the position (excluding two keywords); when it is determined that there are no other keywords, the post-context information of the current position keyword is set to the content from the current position keyword to the end of the block information (excluding the current position keyword).

[0073] As a specific example, assuming that the current block information is "Brand X electric vehicles have a range of 500 kilometers, which is very suitable for users' travel, just like the brand Y electric vehicle automatic driving interface meets the user's travel needs and is very competitive", the number N is 3, and assuming that the keywords of the preset demand vocabulary include "electric vehicle", "interface" and "mileage", when the keywords "electric vehicle range" and "electric vehicle automatic driving interface" meet the derivation rationality conditions, the keyword "interface" can be derived forward to the first "electric vehicle" (that is, the "electric vehicle" in "brand Y electric vehicle") to be combined into the keyword preprocessing result. Since only one keyword is retained in the target structure, the second "electric vehicle" derived forward from the keyword in the block information (that is, the "electric vehicle" in "brand X electric vehicle") cannot be combined with the previously combined "electric vehicle range", but since the number N value is large enough, the second "electric vehicle" can be retained, and the final keyword "interface" corresponds to the position keyword in the preprocessing result as "electric vehicle automatic driving interface". After keyword preprocessing, the keywords "interface" and "mileage" are determined to be the main information of the block information. For the two position keywords "electric vehicle range" and "electric vehicle automatic driving interface" of the preprocessing results, assuming that the number of minimum unit document information N is 3, the preceding text information corresponding to the position keyword "electric vehicle range" is "brand X", and the following text information corresponding to the position keyword "electric vehicle range" is "500 kilometers is very suitable for users' travel conditions like brand Y", and the preceding text information corresponding to the position keyword "electric vehicle automatic driving interface" is "kilometers is very suitable for users' travel conditions like brand Y", and the following text information corresponding to the position keyword "electric vehicle automatic driving interface" is "It meets users' travel needs and is very competitive."

[0074] In an optional embodiment, in step S203, information is derived from the first keyword based on the first processing result, and the information collection to be compared includes:

[0075] Step S231, reading any first keyword in sequence according to the position sequence represented by the first position information and using any first keyword as the current derived keyword;

[0076] Step S232, deriving information for the current derived keyword at least according to the current derived node and the current derived position to obtain a derived result, wherein the current derived node is the position of the target unit document information in the block information, the target unit document information is the longest unit document information derived from the current derived keyword in the block information, the current derived position is the position of the current derived keyword in the block information, and the current derived position is determined by the first position information;

[0077] Step S233: Generate a collection of information to be compared according to the derived result and the first subsequent information corresponding to the current derived keyword.

[0078] Wherein, information is derived from the current derived keyword at least according to the current derived node and the current derived position, and the derived results include:

[0079] Step S2321, taking the beginning of the block information as the starting derived node, calculating the number of unit document information between the current derived node and the current derived position, and obtaining a calculation result;

[0080] Step S2322, comparing the calculation result with a preset value to obtain a first comparison result, wherein the first comparison result is used to determine whether to perform a cyclic derivation on the current derived keyword;

[0081] Step S2323, in response to determining that the calculation result is less than a preset value according to the first comparison result, determining whether the current derived keyword exists in the preset demand word library, and obtaining a first determination result;

[0082] Step S2324, in response to determining according to the first judgment result that the current derived keyword does not exist in the preset demand vocabulary, generating a derived result according to the current derived keyword and the current derived position.

[0083] In the present invention, after preprocessing the keywords, information is derived according to the keyword preprocessing results. An optional information derivation process can be as follows: Figure 7As shown, firstly, the keyword position in the first position information is obtained and the keyword position is used as the current derivative position. Then, the position keyword corresponding to the current derivative position is read and the position keyword is used as the current derivative keyword. Further, the derivative node is extracted from the preprocessing result of the position keyword (at least including the derivative node, previous text information and subsequent text information corresponding to the position keyword) as the current derivative node, and then the document information between the current derivative node and the current derivative position is obtained, and the number of unit document information between the current derivative node and the current derivative position is calculated (recorded as Q). Further, the number Q is compared with the preset value 1. When the first comparison result determines that the number Q is less than the preset value 1, it is determined whether the current derivative keyword exists in the preset demand word library. When it is determined that the current derivative keyword does not exist in the preset demand word library, the original position keyword and the position of the original position keyword are used as the derivative result. Further, the position keyword of the next position is read to derive information.

[0084] In an optional embodiment, the document information processing method further includes:

[0085] Step S2325, in response to determining that the current derived keyword exists in the preset demand word library according to the first judgment result, determining whether the current derived keyword belongs to the target category keyword, and obtaining a second judgment result;

[0086] Step S2326, in response to determining that the current derived keyword belongs to the target category keyword according to the second judgment result, generating a derived result according to the current derived keyword and the current derived position.

[0087] Still Figure 7 As shown, when it is determined according to the first judgment result that the current derived keyword exists in the preset demand vocabulary, it is judged whether the current derived keyword belongs to the target category keyword (such as: a specific keyword input by the user). When it is further determined that the current derived keyword belongs to the target category keyword, the original position keyword and the position of the original position keyword are used as derivative results.

[0088] In an optional embodiment, the document information processing method further includes:

[0089] Step S2327, in response to determining that the current derived keyword does not belong to the target category keyword according to the second judgment result, the current derived keyword is converted into the first previous context information corresponding to the next first keyword.

[0090] Still Figure 7 As shown, when it is determined that the current derivative keyword does not belong to the target category keyword, it is determined that there is no corresponding derivative result at the current derivative position, and the current derivative keyword is converted into the previous text information corresponding to the next position keyword.

[0091] In an optional embodiment, the document information processing method further includes:

[0092] Step S2328, in response to determining that the calculation result is greater than or equal to the preset value according to the first comparison result, updating the current derived keyword at least according to the current derived node to obtain an updated derived keyword;

[0093] Step S2329, determine whether the updated derived keywords meet the derivation rationality condition, and obtain a third determination result; determine the derivation result according to the third determination result.

[0094] Still Figure 7 As shown, when the first comparison result determines that the quantity Q is greater than or equal to the preset value 1, the quantity Q is compared with the preset value 2. Then, when the comparison determines that the quantity Q is greater than or equal to the preset value 2, the midpoint between the current derivative node and the current derivative position is used as the derivative point, and the field between the derivative point and the current derivative position (including the current derivative keyword) is used as the new derivative keyword corresponding to the current derivative position (updated derivative keyword), and then it is determined whether the new derivative keyword meets the derivation rationality condition. When it is determined that the new derivative keyword meets the derivation rationality condition, the new derivative keyword is used as the new position keyword corresponding to the current derivative position; when it is determined that the new derivative keyword does not meet the derivation rationality condition, the position of the new derivative keyword is used as the new derivative node corresponding to the position keyword corresponding to the current derivative position, and then the quantity Q is re-determined according to the aforementioned steps based on the position keyword and the new derivative node.

[0095] Still Figure 7As shown, when the comparison determines that the number Q is greater than or equal to the preset value 1 and less than the preset value 2, the current derivative node is used as the derivative point, and the field between the derivative point and the current derivative position (including the current derivative keyword) is used as the new derivative keyword corresponding to the current derivative position (updated derivative keyword), and then it is determined whether the new derivative keyword meets the derivation rationality condition. When it is determined that the new derivative keyword meets the derivation rationality condition, the new derivative keyword and the current derivative position are used as the derivative result corresponding to the position keyword; when it is determined that the new derivative keyword does not meet the derivation rationality condition, it is determined whether the result of step 3.4.3.3 exists, and when the result exists, the result of step 3.4.3.3 is used as the information derivative result of the position keyword (including the corresponding position); when the result does not exist, it is determined whether the new derivative keyword belongs to the target category keyword. Further, when the new derivative keyword belongs to the target category keyword, the original position keyword and the position of the original keyword before the start of the process are determined as the derivative result; when the new derivative keyword does not belong to the target category keyword, it is determined that there is no corresponding derivative result for the current derivative position, and the position keyword of the current derivative position is converted into the previous text information related to the next position keyword.

[0096] In an optional embodiment, the document information processing method further includes:

[0097] Step S251, taking any first keyword as the current derived keyword;

[0098] Step S252, deriving and updating the current derived keyword according to the first previous text information corresponding to the current derived keyword and the unit document information of the preset derived quantity, to obtain an updated derived keyword;

[0099] Step S253, determining whether the updated derived keywords meet the derivation rationality condition, and obtaining a fourth determination result;

[0100] Step S254, in response to determining that the updated derived keyword meets the derivation rationality condition according to the fourth judgment result, cyclically derive the current derived keyword and update the current derivation number of the current derived keyword;

[0101] Step S255, in response to determining according to the fourth judgment result that the updated derived keyword does not meet the derivation rationality condition, a derivation result is determined at least according to the current derivation number.

[0102] Another alternative information derivation process can be as follows Figure 8As shown, firstly, the keyword position in the first position information is obtained and the keyword position is used as the current derivative position. Then, the position keyword corresponding to the current derivative position is read and the position keyword is used as the current derivative keyword. Further, the derivative node is extracted from the preprocessing result of the position keyword (at least including the derivative node, previous text information and subsequent text information corresponding to the position keyword) as the current derivative node, and then the document information between the current derivative node and the current derivative position is obtained, and the number of unit document information between the current derivative node and the current derivative position is calculated (recorded as Q). Further, the unit document information of the first preset derivative number (recorded as A) is added forward to the current derivative position as the updated derivative keyword, and the current derivative number is increased once, and it is judged whether the updated derivative keyword meets the derivative rationality condition. When the derivative rationality condition is met, it is judged whether the current derivative number is less than or equal to the number Q. When the current derivative number is less than or equal to the number Q, the derivative keyword and the derivative number are cyclically derived and updated.

[0103] Still Figure 8 As shown, when the updated derived keyword does not meet the derivation rationality condition, the current derivation position is increased forward by the second preset derivation number (denoted as B, where B=AC, 1≤C≤A) of unit document information as the updated derived keyword, and the current derivation number is increased once to determine whether the updated derived keyword meets the derivation rationality condition. When the derivation rationality condition is met, it is determined whether the current derivation number is less than or equal to the number Q. When the current derivation number is less than or equal to the number Q, the derived keyword and the derivation number are cyclically derived and updated.

[0104] Still Figure 8 As shown, when the updated derivative keyword still does not meet the derivation rationality condition, the number of unit document information added to the current derivative position is further reduced by one, and the derivation rationality judgment is still performed according to the above content. When it is judged that the updated derivative keyword meets the derivation rationality condition and the current derivation number is greater than or equal to the value 1, the current updated derivative keyword and the corresponding position are determined as the derivation result. When it is judged that the updated derivative keyword meets the derivation rationality condition and the current derivation number is less than the value 1, it is judged whether the current updated derivative keyword belongs to the target category keyword. When it belongs to the target category keyword, the current updated derivative keyword and the corresponding position are determined as the derivation result; when it does not belong to the target category keyword, it indicates that the current position keyword is not suitable for information derivation, and the current derivative position is deleted from the first position information.

[0105] In an optional embodiment, in step S204, the information collection to be compared includes multiple first information groups, any one of the first information groups is composed of first derivative information and first requirement information, the first derivative information is determined by the derivative result corresponding to any one of the first keywords in the document to be processed, the first requirement information is the requirement information obtained by matching the first derivative information in the first subsequent information corresponding to any one of the first keywords according to the preset matching requirement, the reference information collection includes multiple second information groups, any one of the second information groups is composed of second derivative information and second requirement information, the second derivative information is determined by the derivative result corresponding to any one of the second keywords in the reference document, the second requirement information is the requirement information obtained by matching the second derivative information in the second subsequent information corresponding to any one of the second keywords according to the preset matching requirement, the second subsequent information is determined by the second processing result, and the information collection to be compared is compared with the reference information collection to obtain the target information collection including:

[0106] Step S241, comparing any one of the first derivative information with any one of the second derivative information to obtain a second comparison result, wherein the second comparison result includes a similarity between any one of the first derivative information and any one of the second derivative information;

[0107] Step S242, in response to determining that the similarity is less than or equal to a preset similarity threshold according to the second comparison result, generating a target information collection according to any one of the first derivative information and any one of the second derivative information;

[0108] Step S243, in response to determining that the similarity is greater than a preset similarity threshold according to the second comparison result, compare the first requirement information corresponding to any one of the first information with the second requirement information corresponding to any one of the second derivative information to obtain a third comparison result;

[0109] Step S244, in response to determining that the first requirement information is different from the second requirement information according to the three comparison results, a target information collection is generated according to a first information group corresponding to any one of the first derivative information and a second information group corresponding to any one of the second derivative information.

[0110] In the present invention, after the derived results are obtained through information derivation, the derived information is extracted from the derived results (e.g., the location keyword is "substation", and the derived information is "220VXX substation"), and the subsequent information corresponding to the location keyword is extracted from the keyword preprocessing result. Then, the demand information corresponding to the derived information is matched from the subsequent information according to the user's demand, such as Fig. 9As shown, user requirements may include but are not limited to: numerical matching requirements, content matching requirements, and other matching requirements. Furthermore, the derivative information corresponding to each position keyword and the requirement information are combined into an information group, and the information group is sorted to obtain a data collection corresponding to the document. It should be noted that the sorting basis may be but is not limited to one of the following: numbers, symbols, letters, and Chinese characters.

[0111] When performing information comparison, first compare any first derivative information in the data collection to be compared with any second derivative information in the benchmark data collection to determine whether there is first derivative information that meets the similarity requirements (that is, the similarity is less than or equal to the preset similarity threshold). When there is no second derivative information that meets the similarity requirements in the benchmark data collection, the first derivative information is added to the target information collection.

[0112] When there is second derivative information that meets the similarity requirement in the reference data collection, the first requirement information corresponding to the current first derivative information is further compared with the second requirement information corresponding to the second derivative information. When the first requirement information is the same as the second requirement information, it is determined that there is no difference between the two information groups. Then, the next first derivative information in the data collection to be compared is traversed and the difference is compared. When the first requirement information is different from the second requirement information, the information group consisting of the first derivative information and the first requirement information is added to the target information collection.

[0113] It should be noted that after the target information collection is determined by comparison, the target information collection can be converted into a file in a common format (such as a document, a table, etc.) so that the user can flexibly access it.

[0114] In an embodiment of the present invention, a document to be processed and a benchmark document are first obtained, then the document to be processed is preprocessed to obtain a first processing result, and the benchmark document is preprocessed to obtain a second processing result, wherein the first processing result is at least used to determine a first keyword, which is a keyword to be derived in the document to be processed, and the second processing result is at least used to determine a second keyword, which is a keyword to be derived in the benchmark document, and then information is derived from the first keyword based on the first processing result to obtain an information collection to be compared, and information is derived from the second keyword based on the second processing result to obtain a benchmark information collection, and finally, a difference comparison is performed between the information collection to be compared and the benchmark information collection to obtain a target information collection, wherein the target information collection is used to characterize the difference between the information collection to be compared and the benchmark information collection.

[0115] It is easy to understand that the above method determines the keywords to be derived in the processed document and the benchmark document and the preceding and following information of each derived keyword by performing refined preprocessing operations such as segmentation, keyword matching, and structural division on the processed document and the benchmark document, and then derives information from the derived keywords based on the processing results obtained from the preprocessing to obtain an information collection containing derived information and required information. Then, by performing a difference comparison between the information collection to be compared corresponding to the processed document and the benchmark information collection corresponding to the benchmark document, the purpose of accurately and efficiently processing the document information in a manner that can meet the user's customized needs is achieved, thereby achieving the technical effect of improving the accuracy and efficiency of document information processing and saving costs, and thus solving the technical problems of the prior art in that the document information processing accuracy is poor and the information deriving depends on large artificial intelligence models, resulting in high costs.
