s210, acquiring configuration information for PDF document analysis; the configuration information comprises an analysis template and an analysis rule and a storage rule corresponding to the analysis template.
In the embodiment of the application, a user can configure PDF document analysis through terminal equipment. The parsing template can be a document template which is used by a user in normal operation, and each user can configure the parsing template according to the document template which is used by the user, such as an asset and debt table, a profit list, a debit note or a payment note which are used by the user.
After the user uses the document template as the parsing template, the user may configure parsing rules corresponding to the parsing template, and take the document template shown in fig. 3 as an exemplary description, where the document template is a payment form, and the parsing rules may be configured as: 1) reading the content of the corresponding number of the second row and the second column; 2) reading the content of the third row corresponding to the "date"; 3) reading the content of the corresponding 'payment unit' in the fourth row and the second column; 4) reading the content corresponding to the total sum in the second column of the fifth row; … …, etc., so that the PDF document can be parsed according to the configured parsing rule when being parsed.
In the embodiment of the application, the analysis of format contents can be reduced by configuring the analysis template; for example, in the payment sheet, the "payment unit" in the fourth row and the first column may not be analyzed; the "total amount" in the fifth row and the first column may not be analyzed.
Furthermore, in the embodiment of the application, through the configuration of the parsing rule, some contents which do not need to be parsed can be subjected to non-parsing processing, so that parsing efficiency is improved. For example, in the payment order, the content corresponding to the "summary" in the sixth row and the second column may not be analyzed through configuration.
In the embodiment of the present application, the analysis rule may also be an analysis rule for specific content, for example, when the content read in the form below the 7 th row and the first column "hundred" in the payment order is x, the analysis data may be output as null, and the like.
The parsing rule in the embodiment of the present application may also be various parsing rules for PDF document parsing, which are known by those skilled in the art now and in the future, and will not be described in detail herein.
The storage rule in the embodiment of the present application may be that the analysis data in the corresponding analysis template is configured to be stored in the target location in the target database, for example, after the content of the corresponding "number" in the second row and the second column in the payment order is analyzed, the analysis data is stored in the first column in the database table.
The storage rule in the embodiment of the present application may also be a target database in which the configuration analysis data needs to be stored.
And S220, when the PDF document to be analyzed is received, identifying key information in the PDF document to be analyzed, and calling a target analysis template, a target analysis rule and a target storage rule which are matched with the key information according to the key information.
In this embodiment of the present application, an electronic device (for example, the server/terminal device shown in fig. 1) on which the PDF document parsing method operates may receive a PDF document to be parsed in a wired connection manner or a wireless connection manner. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G/5G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
In the embodiment of the present application, when configuring the parsing template, the user may configure an identifier corresponding to the parsing template, for example, the identifier may be header information of a document template, such as a "payment order" shown in fig. 3; header information of the document template and the size of the document template may also be used, for example, as shown in fig. 3, the identifier corresponding to the parsing template is configured as a "bill of payment" and the document size is configured as a small form. It will be appreciated that document size may also be identified in other suitable, readily distinguishable, forms.
In the embodiment of the application, the identified key information is matched with the identifier of the analysis template, so that the target analysis template, the target analysis rule and the target storage rule which are matched with the key information are obtained.
And S230, analyzing the PDF document to be analyzed according to the analysis rule of the target analysis template to generate analysis data.
In the embodiment of the present application, the parsing rule may be a parsing rule corresponding to a target parsing template, for example, referring to fig. 3, contents corresponding to "numbers" in the second row and the second column are read, and contents of target positions that need to be read in sequence may be configured corresponding to the template of the payment order. The target position can be set by the row and column coordinates or by the key value.
And S240, storing the analysis data into a target database according to the storage rule of the target analysis template.
According to the embodiment of the application, the analysis data are stored in the target database according to the storage rule of the target analysis template, so that the analysis data can be stored according to the data structure desired by a user, and manual format adjustment is not needed. For example, referring to FIG. 3, after reading the corresponding "number" of the second column in the second row, it is stored to the numbered column in the database.
In one embodiment, step S210 includes:
s211, acquiring the identity information of the user.
The user can firstly register an account on the terminal device, the account is bound with identity information for distinguishing different users, and the identity information can be an account name, a user job number or a unit name and a job title of the user.
In one example, the identity information is the name of the user, and the name of the job, so that the staff of the job in the job can use the same configuration information for resolution, and information exchange between different staff of the job is facilitated.
S212, acquiring configuration information bound with the identity information according to the identity information.
In one example, after the user logs in to the account, the user performs configuration, and the configured configuration information is associated with the account, so that the user can directly call the configuration information during subsequent login.
In one example, the authority of the configuration information can be set, the identity of the same entity name and the same job can be set, and only the account name with the configuration authority has the authority of the configuration information.
In one example, any account has the authority to configure information so that the PDF document parsing tool can follow personal preferences.
In one embodiment, step S220 includes:
s221, identifying block elements in the PDF document to be analyzed, wherein the block elements comprise characters, tables or graphs.
S222, identifying key information contained in the block elements, matching the key information with the analysis template, and calling a target analysis template matched with the key information.
In the embodiment of the present application, the block elements in the PDF document to be parsed are identified by using the existing picture identification technology, which is not limited in the embodiment of the present application.
In one example, the block elements may be distinguished according to the spacing of pixel points of the PDF document. After the first block element is identified, two lines are empty lines, and the pixel point of the next line is another block element.
And under the condition that the block element is identified as the character, reading the character content in the character, matching the character content with the analysis template, and calling a target analysis template matched with the character content.
In one example, the target parsing template for textual content may be a universal template.
In one example, the target parsing template of the text content may be a matching target parsing template according to a keyword group in the text content, and a general template is adopted in no matching.
In the embodiment of the present application, the parsing rule of the universal template may be reading characters line by line.
Reading header information in the table in the case that the block element is identified as the table; matching the header information with the analysis template, and calling the target analysis template matched with the header information.
Reading character information or pattern information in the graph under the condition that the block element is identified as the graph; matching the character information or the pattern information with an analysis template, and calling a target analysis template, a target analysis rule or a target storage rule matched with the character information or the pattern information.
In one example, the graph is a data graph, and the text information in the reading graph can be coordinate axis information in the reading graph.
In one example, in the case that the block element is identified as a graph, the parsing rule may be to identify whether a coordinate axis is included in the graph, and in the case that the coordinate axis is included, the coordinate axis information is read, and the target parsing template is matched through the coordinate axis information.
In one example, where the graph is a data graph, the parsing rule may be to read a peak value of the graph, a trough value of the graph, or trend information of the graph (e.g., how much the scale is up or down).
In one example, in the case where no coordinate axes are included in the recognition graph, the parsing rule may be to read RGB values for each pixel point position.
In one embodiment, step S230 includes: reading the content of the target position according to the target position set by the analysis rule, and generating analysis data; and/or the presence of a gas in the gas,
and reading the content of the target position according to the target position and the target processing mode set by the analysis rule, and performing data processing according to the target processing mode to generate analysis data.
In one example, in the PDF document to be analyzed, one block element is identified as a form, header information in the read form is a "payment bill", and the read form is matched with an analysis template in the configuration information, so as to obtain an analysis rule and a storage rule corresponding to the analysis template being the "payment bill".
As an example, the parsing rule may be, for example, referring to fig. 3, reading the content corresponding to the "number" in the second row and the second column, and the content of the target location that needs to be read in sequence may be configured corresponding to the template of the payment slip. The target position can be set by the row and column coordinates or by the key value.
As an example, the parsing rule may also be that, for example, referring to fig. 3, the content of the third row is read as "10/21/2020", and converted into "2020/10/21" to generate the parsing data.
In one embodiment, the reading the content of the target position and performing data processing according to the target processing mode according to the target position and the target processing mode set by the analysis rule, and the generating of the analysis data specifically includes:
and under the condition that the content of the read target position is the option frame, acquiring RGB values of the option frame, determining the state of the option frame according to the RGB values, and generating analysis data.
Specifically, the read content is an option box identifier, and the RGB values of the option box are read to determine whether the value is selected or unselected. For example, if the RGB value of the tab box id is read as (192,192,192), the color of the tab box is gray and the status is selected. And generating the data with the analysis data in the selected state. When the RGB value of the tab box identifier is read to be (255,251,240), the color of the tab box is white and the status is unselected. And generating data with the analysis data in the unselected state.
It should be noted that, in the embodiment of the present application, the value of the option box is determined to be the value in the selected or unselected state according to the RGB values of the option box, and the range of the RGB values may be set by the user according to the personalized requirements.
In an example, the read content is a hierarchical number identifier, and an analysis rule may be configured according to the characteristics of the hierarchical number identifier, for example, the size of the hierarchical number identifier is read, and the larger hierarchical number identifier is the document content of the first hierarchy; the level number identifies moderate document content as a second level; the tier number identifies the smaller document content as a third tier.
In one embodiment, the configuration information further includes a data archiving rule, and as shown in fig. 4, the PDF document parsing method further includes step S250: and archiving or clearing the analytic data in the target database according to the data archiving rule.
In an example, the analysis template may be configured as a document template of a payment order, and the document template is stored in different payment units, that is, the analysis data of the payment unit a is stored in a sub-list of the target database AA.
In one example, a document template with a parsing template of B may be configured and purged from the target database within a week after the parsing data is generated.
In one embodiment, step S220 further includes, before:
s2201, obtaining the format information of the PDF document to be analyzed.
Existing PDF documents can be divided into two formats: one is Acroform published 1997 and one is XFA Forms published 2002.
And S2202, reading the content in the PDF document to be analyzed by adopting a reading mode corresponding to the format information according to the format information.
For an Acroform format PDF document, data is analyzed by reading the content under the target row coordinates and the target column coordinates.
