Abstract

The connection relationship of a web page is expressed in the form of a graph consisting of multiple nodes including at least one of true, optional, and numeric nodes corresponding to true, optional, and numeric variables used in the reasoning theory of an expert system and multiple connecting lines connecting and any two nodes among multiple nodes. By implementing the connection relationship through script language or form input or anchor, a source code of each web page composing a welfare mall website is automatically generated. In addition, for the already formed welfare mall website, it is possible to obtain the source code by using an HTTP command and then analyze and display the HTTP command in the form of the graph.

Description

WELFARE MALL WEB SITE MANAGEMENT SYSTEM BASED ON THEINFERENCE THEORY OF THE ARTIFICIAL INTELLIGENCE EXPERTSYSTEMS}

The present invention relates to a system and method for managing a welfare mall web site, and in detail, based on the inference theory of an artificial intelligence expert system, the connection relationship between web pages is represented by a visual graph, and the source code of the web page is generated using this. It relates to a system and method for creating and managing a welfare mall web site by automatically generating it.

Expert system refers to artificial intelligence software that embeds the knowledge of field experts and is programmed to apply them to real problems and solves practical problems like a field expert. As a way of expressing in the system, what is called a rule is used. The rules take the form:

IF… (Conditional statement)

THEN… (Act statement)

The method that the expert system uses the expert knowledge of human experts expressed by the rule to solve the actual problem is called inference. Inference is the action statement shown in the THEN clause if the conditional statement shown in the IF clause of the rule is true. Is to do. However, since there are multiple rules rather than one, it is necessary to repeat the execution of the conditional statement and the action statement while connecting the rules to each other.

On the other hand, variables appear in conditional statements or action statements of rules. For example, consider the following set of animal classification rules.

IF "feed the baby" = TRUE

THEN Type 1 = Mammal

IF type 1 = mammal

AND age <5

THEN type 2 = baby mammals

In the above example, "feed the baby", type 1, type 2, age, etc. are called variables, and TRUE, mammals, 5, baby mammals, etc. are called constants. There are three types of variables: true, optional, and numeric. In the example above, the "feed the baby" variable is

It is a true variable that can have TRUE (True) or FALSE (False) as a value, type 1 is an optional variable that can have mammals, birds, etc. as its value, and age is a numeric variable that can have a number as its value. to be.

Now, the software that understands the correlation between these rules and proceeds with inference while asking appropriate questions according to the order and in the form of variables shown in the rules to draw conclusions (answers) is called the Inference Engine. . For example, if you reason about the two rules in the example above, the following dialogue between the reasoning engine and the user will follow.

Is it true to "feed the baby"?

Yes

" How old are you?

3

Conclusion: "Baby mammals".

To express these rules in an easy-to-understand manner, a Rule Diagram is used. A knowledge analysis diagram is a diagram that expresses the knowledge of a human expert in a graph form. It is not only easy to express knowledge, but also maintenance of knowledge is easy because you only need to fix the corresponding part of the graph when knowledge changes. In addition, the knowledge expressed as a graph is automatically converted into rules and can be immediately used for inference by an inference engine.

A knowledge analysis diagram that can generate the rule of the example above is shown in FIG. 1.

If the expert's knowledge changes, either change the value of the node in the graph corresponding to the rule (for example, if you are younger than 3 years old, change "age <5" to "age <3" for baby mammals. .), if a new rule is added, add a node, or change the arc between nodes as needed. In this way, expert knowledge can be easily maintained.

In addition, software that can generate rules like the above example from this knowledge analysis diagram is also possible, and there are actually developed ones (eg, UNIK-LIFT). The rules created in this way are input to an inference engine (eg, UNIK-BWD) and used for inference.

Meanwhile, the welfare mall website is a collection of numerous web pages that are meaningfully connected to each other. This hyperlink between web pages is similar to the reasoning process using the rules of the expert system.

The present invention has been made in light of this point, and aims to provide a method and tool for easily managing and producing a welfare mall web site by showing the connection relationship between web pages in a graph based on the inference theory of an artificial intelligence expert system. .

An object of the present invention is to provide a welfare mall web site management system and method capable of automatically creating a welfare mall web site based on the connection relationship between web pages constituting the welfare mall web site.

Another object of the present invention is to provide a welfare mall web site management system and method capable of displaying a connection relationship between web pages constituting a welfare mall web site in a form that can be easily grasped visually.

Another object of the present invention is to provide a welfare mall web site management system and method capable of extracting connection relationship information between web pages from an already formed welfare mall web site and displaying it in a form that can be easily grasped visually. .

Another object of the present invention is to provide a welfare mall web site management system and method capable of easily correcting the connection relationship between the content of individual web pages constituting the welfare mall web site and web pages.

In the welfare mall web site management system of the present invention for achieving such an object, the user wants to build a graph made of a plurality of nodes and a plurality of connecting lines connecting any two nodes among a plurality of nodes. An authoring interface that allows you to create a connection relationship between web pages of the Welfare Mall website, a storage device that stores information related to a number of nodes and connection lines constituting a graph, and the source of a web page using information expressed in graphs It includes a code generator that automatically generates a code, and the plurality of nodes includes a true type node, a selection type node, and a numeric type node respectively corresponding to the true type, the optional type, and the numeric type variable used in the inference theory of the expert system, The authentic node is a node that can be connected to another node by a value of "Yes" or "No" for a certain question, and an optional node is a node that can be connected to another node by one of a number of predetermined conditions for a certain question. It is a node, and a numeric node can have a number as a value for a certain question, and is a node that can be connected to other nodes by conditional statements on the value, and the connection relationship between web pages is within the source code generated by the code generator. Is implemented using a scripting language, form input, or anchor in the authoring interface, and as node grouping two or more of the nodes in the authoring interface, the source code is generated by the code generator so that the node grouped nodes consist of one web page. As a result of grouping two or more nodes representing the same question among the nodes in the authoring interface as question variables, the source code is generated by the code generator so that the same question is displayed only once on the web page for the question variable grouped nodes.

Here, it may further include a template database that stores a template file including source codes corresponding to the contents of the rest of the web pages excluding reserved words required for connection between nodes among the source codes of the web pages to be automatically generated. At this time, the code generation unit automatically generates the source code of the web page using the information expressed as a graph and the template file stored in the template database.

In addition, code analysis that receives the source code of a web page as input, analyzes the script language, form, and anchor of the input source code to obtain a connection relationship between web pages, and converts the obtained connection relationship into node and connection line information. A part may be further included, and the code analysis unit may store the source code corresponding to the contents of the rest of the web pages in the template database, excluding connection relationship information indicating the connection relationship between web pages among the source codes.

Using the welfare mall web site management system of the present invention, if the connection relationship between web pages constituting the welfare mall web site is expressed in a graph form, it is automatically generated as a web page, so that a welfare mall web site can be developed easily and quickly, and In terms of mall web site management, if the connection relationship is changed, only the graph can be changed and then automatically generated again, making it easy to maintain the welfare mall web site. Also, for the welfare mall website that has already been developed, the connection relationship can be expressed in a graph and used again for management.

In addition, it is possible to implement a web-based reasoning expert system by applying the reasoning theory used by the present invention to the web in reverse. Since the connection relation of the present invention supports all connection relations between variables in inference, the human expert's knowledge is entered in the form of a graph into the welfare mall web site management system according to the present invention, and then the welfare mall web site is automatically generated and the web When uploaded to the server, it becomes a web-based reasoning site as it is.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic diagram showing a method of creating and managing a welfare mall web site using the welfare mall web site management system of the present invention.

The welfare mall web site management system 210 of the present invention directly receives the welfare mall web site information from the outside, or extracts the welfare mall web site information from the welfare mall web site already formed and uses it as input. The first method of creating a welfare mall web site is to receive information on the welfare mall web site from the outside and generate a plurality of corresponding web pages 220. The web page 220 generated in this way is transmitted to the web server 230 and provided to users through the Internet 240. The change of the welfare mall web site may be made by changing the welfare mall web site information stored in the welfare mall web site management system 210. On the other hand, the method of managing the welfare mall web site that has already been created starts by accessing the welfare mall web site through the Internet 240 and then bringing the welfare mall web site information to the welfare mall web site management system 210. . The information obtained from the welfare mall web site is stored in the welfare mall web site management system 210, and through this, the welfare mall web site can be managed in the same manner as the management of the newly created welfare mall web site.

3 is a schematic block diagram showing an example of the internal configuration of the welfare mall web site management system according to the present invention.

The authoring interface 320 is used to create and edit the structure of the welfare mall web site in the form of a graph such as a knowledge analysis diagram that allows a user who wants to create or manage the welfare mall web site to visually easily grasp the structure of the welfare mall web site. To be able to do it. The authoring interface 320 is linked with the welfare mall web site information database 340 that stores node information and connection information of the welfare mall web site created by the user, and has other information such as the screen composition of the web page. It is also linked with the template database 350 storing template files. The HTML code conversion unit 330 connected to the authoring interface 320 converts the structure of the welfare mall web site created by the user in the form of a graph into a corresponding HTML source code through the authoring interface 320.

The HTML code conversion unit 330 is also interlocked with the welfare mall web site information database 340 and the template database 350, and generates an HTML source code using information stored in these databases. In addition, the welfare mall web site management system 210 includes an HTML code analysis unit 310 that receives information from an existing welfare mall web site and analyzes it to be displayed in a graph form to a user. The HTML code analysis unit 310 divides and stores the analyzed information in connection with the welfare mall website information database 340 and the template database 350 into the welfare mall web site information database 340 and the template database 350, respectively. . The information of the welfare mall web site stored in this way is input through the authoring interface 320 and provided so that the user can view or change it, which may be converted into a new HTML code by the HTML code conversion unit 330.

On the other hand, as described above, the concept of variables in reasoning theory used in the expert system allows all possible connection relationships to be expressed, so if this is used, all possible connection relationships between web pages can be expressed. There are three variables used to express this connection: authenticity type, optional type, and numeric type, and the connection between web pages can be indicated by using these three types of variables. For example, moving to another page by clicking on a menu that often appears on a welfare mall website can be understood as a connection by a selective or authentic variable in inference. In addition, after entering the form, the connection to another page by the confirmation button can be identified as a connection by a numeric variable.

Now, the method of displaying the connection by each variable in a graph and the process of generating the corresponding web page will be described.

First, the authentic connection will be described with reference to FIGS. 4 to 6D. 4 is a graph of the authentic connection, and FIG. 5 shows an example of a web page corresponding to the authentic connection of FIG. 4. 6A to 6D show source codes corresponding to each of the web pages of FIG. 5.

As shown in FIG. 4, the authentic connection is a connection that can have a value of "Yes" or "No" for a certain question (variable). Depending on the value of the question, it leads to different conclusions (Conclusion 1, Conclusion 2). In order to create a web page having such a connection, a user can draw a graph as shown in FIG. 4 by using the authoring interface of the welfare mall web site management system of the present invention.

Next, when the web page generation function of the welfare mall web site management system according to the present invention is used, four web pages corresponding to the graph of FIG. 4 are automatically generated as shown in FIG. 5. The source code file name of each web page is, for example, WBI0HTML, WBI1HTML, WBI2HTML, and WBI3HTML. As shown in FIG. 5, it can be seen that each node of the graph of FIG. 4 corresponds to each web page of FIG. 5. In addition, examples of HTML source codes corresponding to each web page of FIG. 5 are as shown in FIGS. 6A to 6D.

First, looking at the source code of the WBI0HTML file corresponding to the title page 510 of FIG. 5 (FIG. 6A), the title of the document ("Decision FT", "Authenticity") is displayed, and then click the "OK" button. It is designed to be able to move to the page WBI1HTML.

The source code of the question page 520, which is the second page of the authentic connection, is as shown in FIG. 6B.

If the answer to the question is "Yes" and "No", it is described using a script language so that it is connected to the corresponding conclusion pages, WBI2HTML and WBI3HTML, and the input method is to use a radio button. In addition to the radio button, the input method can be hyperlinked to the corresponding conclusion page by using the <A> tag in HTML language, and of course, other input methods such as a check box can be used.

If "Yes" is selected in the question page, the third page 530 is connected to WBI2HTML, and if "No" is selected, the fourth page 540 is connected to WBI3HTML. In each of the conclusion pages 530 and 540, conclusions (Conclusion 1, Conclusion 2) according to each value of the question (variable) of the second page 520 are shown, and the first page 510 by clicking the "Confirm" button. It is connected so that you can return to it.

The second form of connection is optional. 7 and 8 illustrate a graph of a selective connection and an example of a web page corresponding thereto.

As shown in FIG. 7, the optional connection is a connection that can have values such as "Condition 1" and "Condition 2" for certain questions (variables). Depending on the value of the question, it leads to different conclusions (Conclusion 1, Conclusion 2, etc.). In order to create a web page having such a connection, a user can draw a graph as shown in FIG. 7 using the authoring interface of the welfare mall web site management system of the present invention, and accordingly, the web page as shown in FIG. Is automatically generated. The title page 810 and the conclusion pages 830, 840, and 850 are similar to the case of the authentic connection described with reference to FIGS. 4 to 6D. The source code of the second page 820 corresponding to the question page is shown in FIG. 9.

As shown in FIG. 9, it is possible to select and input one of each condition using a radio button, and it is described using a script language so as to connect to a corresponding conclusion page according to the input condition.

The third form of connection is numeric. 10 and 11 respectively show graphs of numerical connections and examples of web pages corresponding thereto.

As shown in FIG. 10, the numerical connection is a connection that can have a number as a value for a certain question (variable). Depending on the value of the question, it leads to different conclusions (Conclusion 1, Conclusion 2). In some cases, special types of numeric concatenation, such as time or date, may be used separately.

In order to create a web page having such a connection, a user can draw a graph as shown in FIG. 10 by using the authoring interface of the welfare mall web site management system of the present invention, and accordingly, the web page as shown in FIG. Is automatically generated. The title page 1110 and the conclusion pages 1130 and 1140 are similar to the case of the authentic connection or the optional connection. The source code of the second page 1120 corresponding to the question page is shown in FIG. 12.

As shown in FIG. 12, the question page 1120 provides an input window to input a value corresponding to the variable a, and is connected to a corresponding conclusion page according to the range of the input value.

Now, a method of creating a welfare mall web site having a connection relationship similar to the knowledge analysis diagram exemplified in FIG. 1 using these three connection methods will be described in detail with reference to FIGS. 13 to 20.

The authoring interface of the welfare mall web site management system of the present invention provides a user interface as shown in FIG. 13. Using such a user interface, the user draws a graph showing the connection between the welfare mall web site consisting of a start node, a truth node, an optional node, a numeric node, and a conclusion node, and creates a web page using the graph. I can. The graph shown in FIG. 13 was created to form a welfare mall web site with contents similar to the knowledge analysis diagram shown in FIG. 1, and expresses the connection relationship between six web pages (animal classification, breastfeeding, age, conclusion). I'm doing it. Here, the first node of the graph is the start node, the “feed the baby” node corresponding to the second node is the authentic node, and the “age” node, which is the third and fourth nodes, corresponds to the numeric node. Each value of the "age" node is connected to the corresponding conclusion node.

A screen leading from the "feeding the baby" page to the "age" web page may be as shown in FIG. 14. That is, one of "Yes" or "No" that may be an answer to a question can be selected by a radio button method, and according to the selection, a corresponding "age" page may be linked. The source code of the web page for implementing the above connection is as shown in FIG. 15. Referring to FIG. 15, when “Yes” is selected, it is connected to “WBI2html”, which is the “age” web page corresponding to “Yes”, and when “No” is selected, the “age” web corresponding to “No” You can see that it is connected to the page "WBI3html".

An example of a "age" web page and its source code are shown in Figs. 16 and 17, respectively. 16 and 17 are screens and source codes connected when “Yes” is selected on the web page of FIG. 14. If you look at the source code, you can see that if the age value entered using JavaScript is less than 5, it is being hyperlinked to the conclusion page "WBI4html". In the case of selecting "No" in the web page of FIG. 14, the generated screen is the same, but the source code is formed to link to another conclusion page corresponding to the case where the age value is less than 1.

However, in some cases, it may be necessary to link to another page based on the result of simultaneously inputting various values.

For example, in the example above, you may need to automatically generate a web page that asks two questions about "feeding a baby" and "age" at the same time. In this case, the automatically generated screen should be as shown in FIG. 18.

To express these points in a graph, we use the concept of "node grouping". In other words, it indicates that the grouped nodes should appear on one screen by grouping two or more nodes constituting the graph. In the graph shown in Fig. 13, "to the pups

If you select "Yes" for the question of "feeding the baby" and the question of "feeding the baby", if you group the "age" page on the left, that is, "node grouping", a web page as shown in FIG. 18 In other words, in the authoring interface as shown in Fig. 13, when the user selects the “feed the baby” page and the “age” page on the left, and then selects the node grouping function of the menu, the two pages become nodes. In Fig. 13, it can be seen that the "feeding the baby" page is marked 1:1 in front of the title, and the "age" page on the left is marked 1:2 in front of the title. The first 1 represents the group identifier, indicating that the two pages belong to the same group.

By the way, even if you select "No" for the question of "feeding a baby", you still have to proceed to the question of asking "age". In the graph of FIG. 13, three pages including the "age" page on the right are displayed as one. Should be grouped.

However, when three pages are grouped and displayed as a group, the automatically generated web page is the same as that of FIG. 19. That is, the question of "age" appears twice. In order to avoid such a problem, the present invention uses the concept of "question variable grouping". That is, not only simple merging of web pages by "node grouping", but also "question variable grouping" is to group the same questions in order to express the question only once because the same question is repeated. That is, when the user selects the left page "age" and the right page "age" in the authoring interface as shown in FIG. 13 and then selects the question variable grouping function of the menu, the two pages of questions are grouped into one. In FIG. 13, it can be seen that both "age" pages are marked as 1:2 in front of the titles, of which the latter 2 represents a question identifier, indicating that the questions on both pages belong to the same question group. In this case, the script part of the automatically generated source code is as shown in FIG. 20.

JavaScript or VBScript can be used as a scripting language used in the automatically generated source code, and the web server side environment can be any HTML or DHTML generation environment such as ASP, PHP, Oracle PL/SQL, etc., not HTML. That is, the present invention does not specify the input method, script language, server-side environment, or the like.

Meanwhile, in the welfare mall web site management system of the present invention, the configuration of the welfare mall web site that has already been created in a process opposite to that described so far can be expressed in the form of a graph and managed through this. For this, the HTML code analysis unit of the welfare mall website management system is used.

For example, suppose there is an HTML file as shown in FIG. 21. The URL of this file is http://misntgsnuackr/~yusong/WBI1html. If you analyze this file, you can see that a file called "WBI2html" is hyperlinked in the "Yes" section. In other words, by analyzing the <A> tag or <FORM> tag of the HTML or DHTML file, and the script language, one completed graph can be extracted from the web pages connected to each other, and this process is the opposite of the above process. Done.

The problem here is to obtain an HTML or DHTML file of the web page source code constituting the welfare mall web site, which is possible by implementing an agent system using HTTP (HyperText Transfer Protocol). In the welfare mall web site management system according to the present invention, an agent system for obtaining the source code of a web page constituting the welfare mall web site is implemented in the HTML code analysis unit. This repeats the process of obtaining the source code of the web page using the URL of the web page corresponding to the root node, and then following the hyperlink expressed in the source code to obtain the source codes of the connected web page again. It is a method of obtaining the source code of the URL by sending an HTTP command to the URL.

That is, when the HTTP command as shown in FIG. 22 is sent to the misntgsnuackr web server, the misntgsnuackr web server responds by sending an HTTP Response including the WBI2html source code. Therefore, the agent according to the present invention can obtain the WBI2html source code. Next, if you analyze the source code of the "WBI2html" file again, you can find the next hyperlink. In the case of connection by optional or numeric variable, the URL of the hyperlinked site can be found by analyzing the <FORM> tag and the script language, and the source code can be obtained again by HTTP. Accordingly, in the welfare mall web site management system of the present invention, information on the welfare mall web site can be obtained from the welfare mall web site already formed and displayed in the form of a graph.

Important elements in a web page include the visual design and content of web pages in addition to the connection relationship between web pages.

Therefore, it is also important to manage content such as visual design or content of each web page separately from the connection relationship between web pages. To this end, the automatic web page generation system according to the present invention uses the concept of a template. In other words, the connection part displays only the connection required by a predetermined reserved word, and the other part uses a template file that has the contents of the web page as it is, and the web page automatic generation system expresses the connection only for the part that needs to be connected, and the rest By leaving it as it is, it does not change the contents of the web page. For example, the template file used in the examples so far is as shown in FIG. 23.

In the template file shown in FIG. 23, <!WGBRANCH> and <!WGINPUTFORM "check" 3 ALIGN=CENTER> indicate that a connection expression is required. The web page automatic generation system according to the present invention does not change the contents of the web page because only this part is changed for connection expression and the rest of the template file is left as it is. In addition, the template file does not necessarily have to be one, and different template files can be placed for each web page, and these various template files are stored and managed in a template database. Therefore, connection and management between web pages with completely different contents can also be achieved by expressing each web page as a template file. In particular, in the case of managing the existing welfare mall web site described above, the contents of the web pages can be maintained intact by changing only the connection part in the HTML or DHTML file obtained by HTTP as a reserved word for connection and then saving the remaining part as a template file.

Reserved words such as <!WGBRANCH> and <!WGINPUTFORM "check" 3 ALIGN=CENTER> shown in FIG. 23 are examples for convenience of description, and the present invention does not specify a specific name or format of these reserved words.

Meanwhile, in order to perform the functions as described above, the welfare mall web site management system must memorize all information related to the graph. Hereinafter, a method of storing graph information and stored data will be described. Since the contents stored in the file and the contents stored in the main memory are very similar, they will be described without distinction.

As described above, the graph is composed of a node and an arc connecting each node. Nodes and connection lines are each stored in an array as shown in FIG. 24.

The information about each node, which is an element of the node array, includes information about the node itself and information about the branch. Information about nodes includes the following.

i) Type of node: Classification of starting node, authentic node, optional node, numeric node, conclusion node, etc.

ii) Node location: coordinates on the screen

iii) Node grouping information: Node group number (ID)

v) Question variable grouping information: Question variable group number (ID)

vi) Template file name

vii) Output file name

viii) Information by node type

-Start and conclusion nodes: title

-Authentic and optional nodes: question, question type (check box, radio button, hyperlink, etc.)

-Numerical node: question, variable name

viii) Other output control information: line break, font and color of text, background color, etc.

Meanwhile, since there are several branches per node, branch information is stored in the form of an array for each node. For example shown in Figure 13

In this example, node 1 (which feeds the baby) has two branches, so it is divided as shown in Figure 25.

Save the information. Each branch information includes the following contents.

i) Type of node to which the branch belongs: Classification of start node, authentic node, optional node, numeric node, conclusion node, etc.

ii) Quarterly type information

-Branch of the starting node: Description

-Branch of authentic node: Answer

-Branch of optional node: Answers (to enable multiple selection)

-Branch of numeric node: branch conditional statement

-Branch of conclusion node: Explanation

iii) Other output control information: line break, font and color of text, background color, etc.

Next, the following are stored as information on the connection line.

i) Type of connection line: Classification of straight line, angled line, etc.

ii) Information about the connection

-Front node: Address of the front node (when saving the main memory device) or ID (when saving a file)

-Previous branch: Address of the previous branch (when saving the main memory device) or ID (when saving a file)

-Rear node: Address of the rear node (when saving the main memory device) or ID (when saving a file)

iii) Other output control information: line color, etc.

Meanwhile, the above-described storage method is only an example for explaining the present invention, and information may be stored in various forms.

Until now, the present invention has been described in detail with reference to preferred embodiments, but this embodiment has been presented for the purpose of understanding the present invention, and the scope of the present invention is not limited to this embodiment.
