Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a schematic flow chart of a contract information auditing method according to an embodiment of the present application, and as shown in fig. 1, a main body executing the method is an auditing device, which may be a desktop computer, a notebook computer, a tablet computer, a smart phone, an intelligent wearable electronic device, a server, and the like. The method comprises the following steps:
step 101: acquiring contract information, extracting the contract information to obtain at least one key information in the contract information; wherein the key information comprises money amount information and time information;
step 102: and for each piece of key information, auditing the key information by using a corresponding auditing model to obtain an auditing result.
In step 101, the contract information is a contract of an electronic edition, and if the contract information is a paper contract, the paper edition can be converted into the electronic edition through an optical character recognition OCR technology. Wherein, optical character recognition refers to a process in which an electronic device (e.g., a scanner or a digital camera) checks characters printed on paper, determines the shape thereof by detecting dark and light patterns, and then translates the shape into computer characters by a character recognition method; the method is characterized in that characters in a paper document are converted into an image file with a black-white dot matrix in an optical mode aiming at print characters, and the characters in the image are converted into a text format through recognition software for further editing and processing by word processing software. It is understood that the contract information of the paper edition can be converted into the electronic edition through other technologies.
Because the contract information contains more characters, in order to improve the auditing efficiency, the information of the contract information is extracted, so that the key information contained in the contract information is obtained. It is understood that different types of contract information include different key information. For example: for the lease contract, the key information can be money information and time information, wherein the money information comprises monthly rent, annual rent and the like; the time information includes the rental period and the respective rental periods in the rental period, etc. For the trade contract, the key information may be information including tax unit price, commodity quantity, total price, etc. The specific information extraction method from the common information is described in the following embodiments.
In step 102, after the auditing device extracts the key information in the contract information, each piece of key information is audited. It should be noted that different key information uses different auditing models, and therefore, the corresponding auditing model is selected to audit the key information. If a certain key information is checked and found to be out of specification, an alarm can be given.
According to the embodiment of the application, the contract information is automatically extracted, and each extracted key information is automatically audited, so that manual participation is not needed, human resources are saved, and the auditing efficiency and accuracy are improved.
On the basis of the above embodiment, the extracting information of the contract information to obtain at least one piece of key information in the contract information includes:
and extracting information of each row in the contract information by using a fifth regular expression to obtain at least one piece of key information in the contract information.
In a specific implementation process, the fifth regular expressions may be generated in advance, it is understood that different types of contract information may adopt different fifth regular expressions, and of course, the fifth regular expressions corresponding to different types of contract information may also be fused into one.
When extracting the information of the same information, the same information is firstly segmented, namely the line feed character is used as a segmentation point to be segmented. And then extracting information by using a fifth regular expression for each row.
Assume that the contract information includes "annual rent: 16 days 02 and 2018 to 15 days 02 and 2019, and the rent containing tax 228000 yuan (capital: two-thousand eight-thousand yuan) in the second to fifth years: 16 days 02 and 2023 and 15 days 02 and 2023 in 2019, each year contains tax rent 248720 yuan (capital: Eryifang, Si wan Ba, Qi and Bi Yiyuan). From the above corpus, it can be seen that the amount information is not an isolated value, but a series of information, including:
the money types (including rent, property charge, water charge, deposit and the like), currency types, original currency values, capital amounts, lower case amounts, whether tax is contained, corresponding tax types, rent time types (annual rent, monthly rent and daily rent), rent area types (square meter rent) and rent corresponding lease periods (start time and end time).
The contents that can be analyzed from the above corpus are:
1. the amount type: renting; original currency value: 228000.00, respectively; and (4) upper case amount: two and ten thousand eight yuan; the lower case amount: 228000 yuan; whether tax is contained: is that; rent corresponding to rent period starting time: year 2018, month 2, day 16; rent corresponding to lease period ending time: year 2019, month 02 and day 15.
2. The amount type: renting; original currency value: 248720.00, respectively; and (4) upper case amount: two eleven eight thousand seven eleven and two eleven and eleven; the lower case amount: 248720 yuan; whether tax is contained: is that; rent corresponding to rent period starting time: year 2019, month 2, day 16; rent corresponding to lease period ending time: 2023, 2 months and 15 days; the rent time type: annual rent.
Each of the fifth regular expressions may be described by the form of the following table. In the following table, the first column indicates a first-level class corresponding to the fifth regular expression, which can also be understood as a large class, the second column indicates a category corresponding to the fifth regular expression, that is, a specific category below the first-level class, the third column is a specific fifth regular expression, and the fourth column is a unit corresponding to the content selected by the fifth regular expression. It can be understood that the regular expressions listed in the following word list are only examples, and the corresponding regular expressions can be written according to actual situations:
after the information of the corpus is extracted through the vocabulary, the following output results can be obtained:
it should be noted that if a long string and a short string are matched at the same time, it is understood that the long string and the short string are relative, the long string refers to a longer character string, and the short string refers to a shorter character string. If two character strings, namely a first character string and a second character string, are matched, if the starting position of the first character string is less than or equal to the starting position of the second character string, the ending position of the first character string is greater than or equal to the ending position of the second character string, namely, the first character string contains the second character string, the first character string is a long string, and the second character string is a short string, at this time, only the long string is output, it should be noted that the case that the starting position of the first character string is equal to the starting position of the first character string, and the ending position of the first character string is equal to the ending position of the first character string is not included here. For example, "second year to fifth year" is matched to both "second year to fifth year" and "second year", "fifth year". Only the "second year to fifth year" is output.
In addition, when matching, the related information may be associated with a lower-case amount or a higher-case amount as an anchor point. The lower case amount is taken as an anchor point as an example as follows:
1) positioning to the position of the lower case amount;
2) from the position of the small amount, the text matching the expression of the following categories, which is closest to the small amount and appears after the previous amount, is found forward:
the categories are: time unit, area unit, time sequence, specific time, electricity charge unit and weight unit; the name of the first class is: the name of the money.
3) From the position of the small writing amount, finding the text which is closest to the small writing amount and is matched by the following expressions in several categories before the next amount:
the categories are: time unit, area unit, electricity charge unit, weight unit; the name of the first class is: the name of the money.
The requirements for the relevant information corresponding to the steps 2) and 3) are as follows:
the expression for each category only outputs the text that matches once. For example, if the nearest information of a category is found from the position of the amount forward, and this information appears after the previous amount, then it is not found backward.
Except for specific time, the position where the information expression related to a certain amount is matched with the text must appear after the previous amount and before the next amount. For example, if one looks forward from the location of the amount to find the nearest one, but this one appears before the previous amount, then one needs to look backward again.
For example, rent per month from 11/19/2021 to 11/18/2023 is one thousand four hundred you ten yuan whole (￥ 114490 yuan), and property fee per month is two thousand six hundred you ten yuan whole (￥ 62969.5 yuan).
The time corresponding to 114490 yuan for rent per month and 62969.5 yuan for property fee per month in the corpus are both from 11/19 th 2021 to 11/18 th 2023. Then this time should be taken as the corresponding specific time for the two amounts.
According to the embodiment of the application, the key information is accurately extracted from the contract information through the fifth regular expression.
On the basis of the above embodiment, the auditing the key information by using the corresponding auditing model to obtain the auditing result includes:
extracting the suspected upper-case money from the at least one piece of key information through a first regular expression;
carrying out numerical value conversion on the suspected capital money;
if no conversion result exists, determining that the suspected capital money is not standard;
if the conversion result exists, matching the suspected upper case sum by using a second regular expression, wherein the second regular expression comprises a plurality of sub-expressions used for checking the non-standard description;
and if the suspected capital-written amount is successfully matched with any sub-expression, determining that the suspected capital-written amount is not standard.
In a specific implementation process, firstly, the auditing device uses a first regular expression to extract a suspected upper-case-sum from the extracted key information, wherein the suspected upper-case-sum is a keyword which may be the upper-case-sum in the contract information. Wherein, the first regular expression may be: [ two, three, four, five, six, eight ninety and ten thousand one two three four five land eight Ba Ji Wan Ba Ji 4e00- \ u9fa5] {0,2} [ two, three, four, five, seven ninety and eight ninety zero one two three four land eight Ji Ba Ji Wan Bai Ji Bai Ji 4e00- _9 fa5 {0,2} ([ two, three, five, seven ninety and eight ninety zero ten thousand one two three four land four seven four hundred Ji Bai 4e00- \\\\ u9fa5] {0,2} {0 } element. It should be noted that the first regular expression may be preset according to actual conditions, as long as the keyword suspected to be the capital-written amount can be extracted.
And after the suspected capital-written amount is obtained, carrying out numerical value conversion on the suspected capital-written amount, wherein the conversion can be carried out by adopting a numerical value conversion tool of Microsoft, and if no result is obtained, determining that the suspected capital-written amount is not standard. It will be appreciated that a plurality of suspected upper case amounts may be extracted from a single contract message, and therefore, each suspected upper case amount may need to be converted and then individually reviewed.
And if so, matching the suspected upper case sum with the conversion result by using the second regular expression again. Wherein, the description of the second regular expression is shown in the following table:
for example: if the suspected capital sum of the conversion result is matched with the second regular expression in the table, reporting that the capital sum is not standard: and a warning prompt of mixed use of traditional Chinese medicine and simplified Chinese medicine.
Thus, the first regular expression serves to roughly audit suspected upper case amounts, filter out some apparent non-compliance, and the second regular expression serves to audit in detail and give specific non-compliance reasons when non-compliance is present.
According to the embodiment of the application, the capital-written amount in the contract information is checked through the first regular expression and the second regular expression, and whether the capital-written amount in the contract information is wrong or not can be accurately identified.
On the basis of the above embodiment, the auditing the key information by using the corresponding auditing model to obtain the auditing result includes:
extracting the suspected compound unit lower case amount from the at least one piece of key information through a third regular expression;
matching the suspected compound unit lower case amount by using a fourth regular expression;
if the matching is successful, determining that the suspected compound unit lower case amount identification is wrong;
if the matching is unsuccessful, extracting a character string from the suspected compound unit lower case amount to obtain a first compound unit lower case amount; wherein the string of characters comprises a number;
carrying out numerical value conversion on the suspected compound unit lower case amount to obtain a second compound unit lower case amount;
if the lower-case amount of the first composite unit is consistent with the lower-case amount of the second composite unit, the suspected lower-case amount of the composite unit is standard, otherwise, the suspected lower-case amount of the composite unit is not standard.
In a specific implementation process, the contract information may include a plurality of composite unit lowercase amounts, where a composite unit lowercase amount is a composite of a unit of the lowercase amount and other units. For example, in the rental contract, "85859.76 yuan/month" and "yuan/month" are composite units. The character may be recognized as "85859, 76-month and 7-month" after OCR or corpus recognition, and it can be seen that the numerical value is wrong and the unit is also wrong. Therefore, the auditing device can extract the suspected compound unit lower-case money amount from the key information through the third regular expression. The third regular expression may be: [ \ d ] [ \ d ]? (. [ \ d \ s \ and ]) {0,15} element {0,2} [ month year ], although other expressions capable of identifying the suspected compound unit lower-case amount are possible, and the specific content of the third regular expression is not limited in the embodiment of the present application.
After the suspected compound unit lower case amount is obtained, a fourth regular expression is used for matching the suspected compound unit lower case amount, wherein the fourth regular expression can be as follows: [, ] \ d {0,2} elements. And if the suspected compound unit lower case amount is successfully matched with the fourth regular expression, the suspected compound unit lower case amount is not normalized, and an alarm is given at the moment.
If the matching is not successful, all character strings consisting of numbers, commas (,) and point numbers (·) are extracted from the suspected compound unit lower case money according to the sequence of appearance in the text, and the first compound unit lower case money is obtained. For example:
the contract information is as follows: from 7/1/2012 to 6/30/2013, the rent is 12,000.00 yuan/month, and the first compound unit lower-case amount extracted is: 12,000.00, and then using a microsoft conversion tool to perform numerical conversion on the suspected compound unit lower writing amount which is not successfully matched, so as to obtain a second compound unit lower writing amount. It should be noted that other conversion tools may also be used for conversion, and this is not particularly limited in the embodiments of the present application. If the conversion fails, the suspected compound unit lower case amount is not standard.
It should be noted that for a lower case amount without a decimal, there may be no comma or click in the corresponding suspected compound unit lower case amount, for example: the rent is 1200 Yuan/month, and the lower-case amount of the first compound unit extracted by the rent is as follows: 1200.
if the conversion is successful, comparing the lower-case amount of the first composite unit with the lower-case amount of the second composite unit, if the lower-case amount of the first composite unit is consistent with the lower-case amount of the second composite unit, indicating that the lower-case amount of the suspected composite unit is standard, otherwise, indicating that the lower-case amount of the suspected composite unit is not standard.
According to the embodiment of the application, the lower-case amount in the contract information is checked through the third regular expression and the fourth regular expression, and whether the lower-case amount in the contract information is wrong or not can be accurately identified.
On the basis of the above embodiment, the time information includes a contract period start time, a contract period end time, a contract period start time, and a contract period end time; the auditing the key information by using the corresponding auditing model to obtain an auditing result comprises the following steps:
normalizing the contract period starting time, the contract period ending time, the contract time period starting time and the contract time period ending time; wherein, the contract period refers to the irrevocable contract period specified by the contract; contract time periods refer to respective time periods in the contract term;
sequencing the starting time of the contract time period and the ending time of the contract time period according to time sequence;
determining that the contract information is not standardized if any one of the following is satisfied:
the first contract time period starting time is different from the contract period starting time;
the end time of the last contract time period is different from the end time of the contract period;
in two adjacent contract time periods, the end time of the previous contract time period is not the day before the start time of the next contract time period.
In a specific implementation process, for a contract, the contract information may include information about contract period and contract time period. There may be situations where contract time periods do not match contract periods, such as: the beginning of the contract time period and the result time are not end-to-end, the set of contract time periods is inconsistent with the contract period, and so on. Therefore, it is necessary to check the contract period and the contract time period. In the contract information, some time information is specific year, month and day, and some time information is not year, month and day, taking a lease contract as an example: : the lease period is "11/2015/2/10/2018/a" third lease year "means" 11/2017/2/10/2018 ". Therefore, the third lease year needs to be normalized to obtain the corresponding year, month and day.
Wherein the time normalization can be achieved by the expression in the following table:
it should be noted that $1 refers to taking the content in the first parenthesis; and $2 means that the contents in the second parenthesis are taken out and converted into numerical values.
For example, the key information extracted from the contract information of the lease contract has the expressions { ' price ': ￥ 1028572.55 Yuan ', ' title _ price ': one Bai, zero two Ba Qiawu Qi Shi two Yuan Wu Yuan Wu, type _ of _ fe ': rent ', ' unit _ of _ time ': year ', ' sequence _ of _ time ': third lease year '.
Expression matching is performed for the sequence _ of _ time (time series) output in the amount information entry according to the above table. And obtaining the information that the sequence time is a time period/time point, a numerical value, a time unit and the like. And (4) directly analyzing the specific time according to the lease start-stop date for the sequence time of the characteristic time point. And 3 of the numerical value 'third lease year' is taken firstly, and then calculation is carried out on the basis of lease start-stop dates to obtain the specific time. For sequence time characterizing the rental period, there are two cases:
1) the numerical value in time indicates the length of time. Such as the first three years and the last five years. The time length is obtained, and the specific time is calculated.
2) The values in time represent the start and end of time. Such as "first year to fifth year" and "second year and third year". The values of the time start and the time end are obtained, and the specific time is calculated.
After the normalization process is completed, the rental period start time and the rental period end time are sorted, for example: the lease period is as follows: 1/6/2015 to 31/5/2017; the lease time periods are respectively as follows: two lease time periods, a first lease time period [2015 year 6 month 1 day to 2016 year 5 month 31 day ] and a second lease time period [2016 year 6 month 1 day to 2017 year 5 month 31 day ], which are ordered to yield: 1/6/2015, 31/5/2016, 1/6/2016, and 31/5/2017.
The first rental period start time refers to the start time of the first rental period in the rental period, i.e., the first rental period start time on day 1 of 6 months on 2015. Day 1 of 6 months of 2015 is also the start time of the rental period.
The last rental period end time is the end time of the last rental period in the rental period. I.e., 5 months and 31 days in 2017. The end time of the lease period is 2017, 5 and 31.
If the lease period and the lease time period do not meet any one of the conditions, the contract information is not specified, and an alarm is given.
According to the embodiment of the application, the accurate examination and verification of the contract period and the contract time period are realized through the preset conditions, and the problem that the contract period does not correspond to the dates of the contract time periods is solved.
On the basis of the above embodiment, the auditing the key information by using the corresponding auditing model to obtain the auditing result includes:
obtaining a plurality of money information in the same contract time period from at least one piece of key information, wherein each money information comprises an original currency value, a time type, an area type and a tax-containing type;
comparing the time type, the area type and the tax-containing type in the amount information to determine different types;
normalizing the original coin values of different types to obtain the original coin value of the same type;
and comparing the original currency values of the plurality of money information under the same type, and if the original currency values are different, determining that the contract information is not standard.
In the specific implementation process, taking a lease contract as an example: the corresponding units may be different for the amount of money in the contract information, such as: daily rent, monthly rent, annual rent, rent corresponding to total area, rent corresponding to unit area, and the like. The review of whether the rent amount conversion is consistent may include the following:
1) and in the same lease time period, whether the rent amount conversion of different time types is consistent or not.
The time types of rent here refer to annual rent, monthly rent, daily rent. If the daily rent is 100 yuan, the monthly rent should be 3000 yuan, and the annual rent should be 36000 yuan.
2) And in the same lease time period, whether the conversion of the rent amounts of different area types is consistent, namely whether the rent amount and the area with the square meter as a unit are consistent with the conversion of the rent amount.
If the house area is: 200 square meters, the monthly rent is 20000 yuan, and the monthly rent per square meter is 100 yuan.
3) And in the same lease time period, whether the conversion between the rent and the tax rate of different tax-containing types in the same time type is correct or not is judged.
If the tax free rent is 10000 Yuan and the tax rate is 6%, the tax containing rent should be 10600 Yuan.
When the auditing is carried out, a plurality of money amount information in the same leasing time period is obtained from the key information, and each money amount information comprises an original currency value, a time type, an area type and a tax-containing type. For example: from 7/1/2012 to 6/30/2013, the house daily rent is 100 yuan, i.e. 3000 yuan/month. Note: the tax rate specified by the contract is 6%. The house area is 50 square meters.
The extracted amount information is:
| original currency value | Rental period | Time type | Area type | Type of tax |
| 100 | 2012-7-1～2016-6-30 | Daily rent | Rent of non-square meters | No tax |
| 3000 | 2012-7-1～2016-6-30 | Monthly rent | Rent of non-square meters | No tax |
As can be seen from the above table, the time types in the two pieces of money information are different, and at this time, the original coin value corresponding to the daily rent can be normalized to the original coin value of the monthly rent, taking 30 days as an example for one month: the normalization formula is as follows: the daily rent amount is 30, which is the monthly rent amount; thus, a daily rental fee is 100 dollars, and a monthly rental fee is 3000 dollars. It is understood that the normalized formula between monthly rent and annual rent is: monthly rent amount 12 is the annual rent amount.
It can be understood that the above embodiment only gives the normalization method with different time types, and for the original currency values with different area types, the normalization formula is: the non-square-meter rent amount is the square-meter rent amount and the rent area. For original currency values with different tax types, the normalization formula is as follows: no tax rent (1+ rent tax rate).
After normalization is complete, a comparison of the original monetary values is made, for example: and comparing the original currency value obtained after the daily rent is normalized with the original currency value which is originally the monthly rent, if the original currency value is consistent with the original currency value, determining that the contract information is standard, and otherwise, determining that the contract information is not standard.
According to the embodiment of the application, the original coin values of different types are normalized into the original coin value of the same type, and whether rent amount conversion in the audit information is consistent or not is judged.
On the basis of the above embodiment, the key information further includes money amount change information, and the money amount information includes a basic money amount and a changed money amount; the auditing the key information by using the corresponding auditing model to obtain an auditing result comprises the following steps:
calculating to obtain the expected changed amount according to the basic amount and the amount change information;
and comparing the estimated changed amount with the changed amount, and if the estimated changed amount is not consistent with the changed amount, determining that the contract information is not standard.
In a specific implementation process, the amount change information can be understood as the floating or descending of the rent, for example, the rent of the first rental year is three thousand two thousand eight earth ten seven two ten seven three yuan two corner eight score (￥ 932867.28 yuan), the rent of the second rental year is gradually increased by 5% year by year on the basis of the last rental year standard, namely the rent of the second rental year is two thousand ten yuan two corner five score (￥ 1028572.55 yuan), the rent of the fourth rental year is one two thousand ten two corner five score (￥ 1080053.01 yuan), the rent of the fifth rental year is two hundred thousand ten thousand three hundred three corner zero three one score three score four month five score four year (￥ 1080053.01 yuan), the rent of the fifth rental year is three hundred thousand ten thousand three score four year (￥ 1080053.01 yuan, the last three score four year ten hundred thousand ten score three score (367) information is the information of the last half three score 30 year, the last three score, the last year, the last three score, the last.
From the analysis of the rent change, the following results are known:
results 1: (the second year)
Variation time: 1/8/2017-31/7/2018; the variation mode is as follows: increment, interval:1 y; variation width: 5 percent; the monthly rent (no tax) value of the currency: 81625.89.
results 2: (third year)
Variation time: 1/8/2018-31/7/2019; the variation mode is as follows: increment, interval:1 y; variation width: 5 percent; the monthly rent (no tax) value of the currency: 85707.18, respectively; other results were slight.
Taking result 1 as an example, the starting time is 2017, 8 and 1 days, the ending time is 2018, 7 and 31 days, the original currency values of the money amounts at the corresponding time are respectively compared, and if the money amounts are consistent (rounding up to two digits after keeping decimal point), the rent change situation is consistent with the rent description. Otherwise, the statement is inconsistent, and the statement of the rent change situation of the review and approval point is inconsistent with the corresponding rent statement.
It should be noted that before the comparison is consistent, the time information and the money amount information need to be normalized, and the normalization may be performed according to the regular expression in the following table:
wherein s denotes a rental period start date; e refers to the rental period end date; the $1 means that the contents which are regularly matched in the first bracket are taken out and the numerical value normalization is carried out; and $2 means take the content that is regularly matched in the second bracket and normalize the value. The variation mode includes attributes of two dimensions, one is variation trend and one is variation frequency. The trend dimension includes: creating, creating and fixed; the variation frequency includes: 1 year (1 y in the example), 2 years, etc. For example, the variation of "increment, interval:1 y" is gradually increased year by year; the variation mode of the increment, once or the decrement, once is one-time variation; the "fixed" is changed in a constant manner; "amount" means varied by amount; "percent" means varying by percentage.
For example: from the second year to the fourth year, the rent is increased by 8 percent year by year on the basis of the rent of the previous year. Note: lease period is from 6/2010 to 20/2015 to 6/2015 to 19/19.
The start time of the variable time is the start time of the rental period + [2 (second year) -1], i.e., 2011, 6 months and 20 days. The end time of the variable time is the start time of the rental period +4 (fourth year), i.e., 6 months and 20 days 2014.
It should be noted that the normalization method of the amount information is consistent with the above embodiment, and is not described here again.
According to the embodiment of the application, whether the changed amount in the identical information is correct or not is checked through the basic amount and the amount change information, and errors in calculation of the changed amount are prevented.
